INSTRUCTIONS TO BIDDERS

1.01 INSPECTION OF SITE
Bidders are required to inspect the site of the work to satisfy themselves by personal examination or by such other means as they may prefer, of the location of the proposed work, and of the actual conditions of and at the site of work. Bidders should plan to inspect the site of the work during the pre-bid meeting and can schedule additional time by special arrangement with the Owner.

Entrance by bidders to the site of the work for purposes of making exploratory excavations will be by special arrangement with the Owner and under conditions established by the Owner. If, during the course of its examination, a bidder finds facts or conditions which appear to be in conflict with the letter or spirit of the project manual, he or she may apply to the Owner, in writing, for additional information and explanation before submitting a bid.

Submission of a bid by the bidder is an acknowledgment that, if awarded the contract, bidder has relied and is relying on bidder’s own examination of (1) the site of the work, (2) access to the site, and (3) all other data and matters requisite to the fulfillment of the work and on their own knowledge of existing facilities on and in the vicinity of the site of the work to be constructed under the contract.

The information provided by the Owner is not intended to be a substitute for, or a supplement to the independent verification by the bidder to the extent such independent investigation of site conditions is deemed necessary or desirable by the bidder. Bidder acknowledges that he or she has not relied upon Owner-furnished information regarding site conditions in preparing and submitting a bid.

1.02 EXAMINATION OF PROJECT MANUAL
Each bidder must thoroughly examine and be familiar with those contract documents contained in the project manual. Submission of a bid constitutes acknowledgment, upon which the Owner may rely, that the bidder has thoroughly examined and is familiar with the project manual. Failure or neglect of a bidder to examine any of the contract documents contained in the project manual in no way relieves bidder from any obligation with respect to his bid or to the contract. No claim for additional compensation will be allowed that is based upon a lack of knowledge of the contract documents or the work.

1.03 INTERPRETATION OF PROJECT MANUAL
Bidders, prospective subcontractors, manufacturers, and suppliers may request interpretation of the project manual prior to bid opening. Requests for interpretation must be directed in writing to David Yeager, Director of Public Works, [email protected], 377 J Street, Crescent City, CA 95531 (707) 464-9506. Requests to clarify the source of materials, equipment, suppliers, or any other matter that does not modify, change, increase,

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
10 OF 86
or decrease the scope of work, requires no action by the Owner other than a response to the bidder requesting the clarification. Requests to clarify possible ambiguous, conflicting, or incomplete statements or designs, or any other clarification that modifies, changes, increases or decreases the scope of work, requires issuance of an addendum by the Owner for the interpretation to become effective.

Reference information has been made available on the City’s website that includes information used by the Engineer to prepare the Contract. The information provided on the website is for use by bidder during preparation of the bid and execution of the Contract. The Owner disclaims responsibility for the interpretation by bidders of the reference information.

In some cases, the information was prepared for design purposes and is not intended to provide all the information required by the bidder to tender a bid, construct the system, and provide start up and commissioning services. Reference information is available on the City’s website https://www.crescentcity.org/rfp_bid.html and includes:

3. BIDDER'S SIGNATURE AND AUTHORITY: If the bid is made by an individual, the bidder’s name, signature, and post office address must be shown; if made by a firm or partnership, the name and post office address of the firm or partnership, a list of the partners, and the signature of at least one of the general partners must be shown; if made by a corporation, the bid must show the name of the state under the laws of which the corporation is chartered, the name and post office address of the corporation, and the title of the person who signs on behalf of the corporation. If the bid is made by the corporation, a certified copy of the bylaws or resolution of the Board of Directors of the corporation must be furnished, showing the authority of the officer signing the bid to execute contracts on behalf of the corporation. If the bid is made by a joint venture, the bid must be signed by a representative of one of the joint venture firms. Additionally, the bid must include a copy of the resolution or agreement empowering the representative to execute the bid and bind the joint venture.

4. BID IRREGULARITIES: Each bid and the information requested, bound in the project manual, must be enclosed in a sealed envelope, and labeled as specified in the Invitation to Bid. Bidders are warned against making erasures or alterations of any kind, and bids containing omissions, erasures, or irregularities of any kind may be rejected. No oral, telegraphic, or telephonic bids or modifications will be considered.

5. MODIFICATION OF BID: Modification of a bid already received will be considered only if the modification is received prior to the time established for receiving bids.

Modifications must be made in writing, executed, and submitted in the same form and manner as the original bid.

6. WITHDRAWAL OF BIDS: Within five business days after the opening of bids, a bidder may withdraw his or her bid, if he or she establishes to the Owner's satisfaction that a mistake was made in preparing the bid. A bidder who wants to withdraw must give written notice to the Owner, specifying, in detail, how the mistake occurred and how the mistake made the bid materially different than it was intended to be. Withdrawal is not permitted for mistakes resulting from errors in judgment or carelessness in inspecting the site of the work or in reading the project manual.

7. MAJOR EQUIPMENT ITEMS: Certain items of major equipment to be provided under this contract are shown on the plans. The bidder must provide the name of the manufacturer of the equipment to be provided for all major equipment. Only one manufacturer may be indicated for each item. By so indicating, the bidder warrants that equipment manufactured and/or supplied by the named manufacturer will be provided on the project unless review of submittal information or performance under tests reveals that the manufacturer is unresponsive to the contract. Failure to indicate a manufacturer for any equipment may render the bid unresponsive to the invitation to bid and may be a basis for rejection of the bid.

The arrangements specified on the drawings are based on a particular manufacturer's equipment. Where the Contractor selects a manufacturer whose equipment arrangement is different than specified, the total amount listed in the bid must provide for a complete operating installation for each equipment item listed, including any and all changes and additions in structure, piping, buildings, mechanical, electrical and control systems and

accessories required to accommodate the listed manufacturer's equipment. The bid must also include the preparation and submission of detailed drawings, calculations, and manufacturer's data to allow evaluation of the proposed equipment and to show all modifications to the work as necessary to accommodate the proposed manufacturer's equipment.

In the event that the Owner, at its sole discretion, determines that the equipment of the manufacturer listed by the Contractor and submitted for review does not meet the requirements of the contract, the Contractor must select and submit for review equipment of another manufacturer which does meet the contract, and no increase in the total amount of the contract will be allowed.

B. ALTERNATIVE MATERIALS AND EQUIPMENT:

The bidder may offer a deductive price to the Owner for supplying alternative or substitute equipment or material for items specified or shown in the plans by listing the specification section, item description, manufacturer, and deductive amount as a supplement to the bid. The bid must be based on supplying equipment or material from manufacturers or suppliers specified or shown on the plans. Alternative or substitute equipment or material will be considered by the Owner after contract award and will not be used in determining the basis of award. Selection of any offered alternate or substitution will be at the Owner’s sole discretion and will be accomplished by issuing a deductive change order for an amount agreed upon.

Manufacturers or suppliers of materials and equipment may offer an alternative product to the Contractor and request that alternatives to specified products be considered equal. Inclusion of such alternatives in the bid is the responsibility of the Contractor.

Inclusion should only be considered if the Contractor believes the offered alternative is equal in quality to the specified product. After award of contract, such offers of alternative products will be reviewed and processed as a substitution provided under paragraph 00 72 00-4.05.

C. BID GUARANTY:

The bid form must be accompanied by a bid guaranty bond provided by a guaranty company authorized to carry on business in the State of California for payment to the Owner in the sum of at least ten (10) percent of the total amount of the bid price, or, alternatively, by a certified or cashier's check, payable to the Owner in the sum of at least ten (10) percent of the total amount of the bid price.

D. DEVIATION FROM CONTRACT:

Neither the Contractor nor the Owner may make an alteration or variation in, addition to, or deviation or omission from the terms of this contract without the written consent of the other party.

E. DIFFERING SITE CONDITIONS:

Pursuant to Public Contract Code Section 7104, the Contractor must promptly, and before such conditions are disturbed, notify the Owner in writing of:

1. Material that the Contractor believes may be material that is hazardous waste, as defined in Section 25117 of the Health and Safety Code, that is required to be removed to a Class I, Class II, or Class III disposal site in accordance with provisions of existing law.

2. Subsurface or latent physical conditions at the site differing from those indicated by information about the site made available to bidders prior to the deadline for submitting bids.

3. Unknown physical conditions at the site, of an unusual nature, differing materially from those both ordinarily encountered and generally recognized as inhering in work of the character provided for in this contract.

The Owner must promptly investigate the conditions, and if Owner finds that such conditions do materially differ, or do involve hazardous waste and cause an increase or decrease in the Contractor's cost of, or the time required for, performance of any part of the

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
60 OF 88
work under this contract, whether or not the work is changed as a result of such conditions, an equitable adjustment will be made, and the contract modified in writing accordingly.

In the event that a dispute arises between the Owner and the Contractor whether the conditions materially differ, or involve hazardous waste, or cause a decrease or increase in the contractor’s cost of, or time required for, performance of any part of the work, the contractor shall not be excused from any scheduled completion date provided for by the contract, but shall proceed with all work to be performed under the contract. The contractor shall retain any and all rights provided either by contract or by law which pertain to the resolution of disputes and protests between the contracting parties.

No claim by the Contractor under this clause is allowed unless the Contractor has given the notice required, except that the Owner may extend the prescribed time.

APPEALS TO THE OWNER'S REPRESENTATIVE: In the event the Contractor disagrees with any determination or decision of the Construction Manager, the Contractor may, within 15 calendar days of the date of such determination or decision, appeal the determination or decision to the Owner's Representative. The Owner's Representative must review the appeal and transmit a decision in writing to the Contractor within 30 calendar days from the receipt of the appeal. Any failure of the Contractor to appeal the decision or the determination of the Construction Manager within the 15-day period constitutes a waiver of the Contractor's right thereafter to assert a claim resulting from such determination or decision.

3. ARBITRATION: All claims, counterclaims, disputes and other matters in question between the Owner and the Contractor that are not resolved between the Owner's Representative and the Contractor will be decided by arbitration if the parties mutually agree, or in a court of competent jurisdiction within the state in which the Owner is located.

PART 3 – SPECIFICATIONS AND DRAWINGS

3.01 INTERPRETATION OF SPECIFICATIONS AND DRAWINGS
A. GENERAL:

The specifications and drawings are intended to be explanatory of each other. Work specified on the drawings and not in the specifications, or vice versa, must be executed as if it were specified in both.

B. REQUEST FOR CLARIFICATION:

In the event the work to be done or matters related to the work are not sufficiently detailed or explained in the contract documents, the Contractor must apply to the Construction Manager for further explanations as may be necessary and must conform thereto so far as may be consistent with the terms of the contract. In the event of doubt or question arising respecting the true meaning of the specifications or drawings, reference must be made to the Construction Manager for a decision. Should the Contractor disagree with the Construction Manager's decision, the Contractor may appeal to the Owner's Representative in accordance with paragraph 00 72 00-2.05 F.2.

3.02 DIVISION OF SPECIFICATIONS AND DRAWINGS
Specifications and drawings are divided into groups for the convenience of the Owner and Construction Manager. These divisions are not for the purpose of apportioning work or responsibility for work among subcontractors, suppliers, and manufacturers.

3.03 DISCREPANCIES IN SPECIFICATIONS AND DRAWINGS
A. ERRORS AND OMISSIONS:

If the Contractor, in the course of the work, becomes aware of any claimed errors or omissions in the contract documents or in the Owner's field work, the Contractor must immediately inform the Construction Manager in writing. The Construction Manager must promptly review the matter and if it is found that finds an error or omission has been made; the Construction Manager must then determine the corrective actions and advise the Contractor accordingly. If the corrective work associated with an error or omission increases or decreases the amount of work called for in the contract, the Owner must issue an appropriate change order. After discovery of an error or omission by the Contractor, related work performed by the Contractor is done at the Contractor’s risk unless authorized by the Construction Manager. In the event the Contractor disagrees with the determination of the Construction Manager under this provision, the Contractor may appeal to the Owner's Representative in accordance with paragraph 00 72 00-2.05 F.2.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
62 OF 88
B. CONFLICTING PROVISIONS:

In cases of conflict between the specifications and drawings, the more stringent governs. Figure dimensions on drawings govern over scale dimensions and detail drawings govern over general drawings. In the event an item of work is described differently in two or more locations on the drawings and in the specifications, the Contractor must request a clarification from the Construction Manager.

C. UTILITIES:

The Owner has endeavored to determine the existence of utilities at the site of the work from the records of the owners of known utilities in the vicinity of the work. The positions of these utilities as derived from such records are shown on the drawings. No excavations were made to verify the locations shown for underground utilities. The service connections to these utilities are not shown on the drawings. It is the responsibility of the Contractor to determine the exact location of utilities and service connections thereto. The Contractor must make its own investigations, including exploratory excavations, to determine the locations and type of existing utilities, including service connections, prior to commencing any work that could result in damage to those utilities. The Contractor must immediately notify the Construction Manager as to any utility discovered by him in a different position than shown on the drawings or that is not shown on the drawings.

Work on utilities must be performed and paid for as follows:

1. Known utilities. The Contractor must provide all labor, equipment, materials, and services necessary to remove, relocate or maintain utilities specified on the drawings. The work on each utility must be performed in a manner satisfactory to the utility owner. The utility owner has the option of doing such work with its own forces at the Contractor's expense or permitting the work to be performed by the Contractor.

2. Service connections. Locations of service connections are not specified on the drawings. The Contractor must provide all labor, equipment, and material to remove, relocate or maintain service connections. The work on service connections must be performed in a manner satisfactory to the service connection owner. The service connection owner has the option of doing such work with its own forces at the Contractor's expense or permitting the work to be performed by the Contractor.

3. Unknown utilities. When a utility is not specified on the drawings, or it is located in a position different from that specified on the drawings, and interferes with the work, a change order based on changed site conditions will be issued in accordance with paragraph 00 72 00-7.02.

Interference with the work is defined as a utility that crosses or projects

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
63 OF 88
into the plane of the work at an elevation between the top and bottom of the work. If it is necessary to remove, relocate, or temporarily maintain the utility, that work must be included in the change order.

The utility owner has the option of doing such work at the Contractor's expense or permitting the work to be performed by the Contractor. In either case, the cost of the work will be included in the change order.

No representations are made that the obligations to move or temporarily maintain the utility and to pay the cost thereof is or is not required to be borne by the owner of such utility, and it is the responsibility of the Contractor to investigate to find out whether or not the cost is required to be borne by the owner of the utility.

The right is reserved to governmental agencies and to owners of utilities to enter upon streets, alleys, rights-of-way or easements for the purpose of making changes in their property made necessary by the work and for the purpose of maintaining and making repairs to their property.

3.04 SUBMITTALS
Where required by the specifications, the Contractor must submit specified information that will enable the Construction Manager to advise the Owner whether the Contractor's proposed materials, equipment or methods of work are in general conformance to the design concept and in compliance with the drawings and specifications. The requirements for submittals are specified in Part B of the project manual.

3.05 CONTRACTOR'S COPIES OF PROJECT MANUALS
Within 10 business days after notice to proceed, the Owner will furnish to the Contractor 4 sets of project manuals including 2 sets of half-size drawings, and 2 sets of fullsize drawings. The Contractor is advised that revisions incorporating changes by addenda will not be incorporated into the reduced or full-size drawings furnished under the provisions of this paragraph. Additional copies of the project manual, if required by the Contractor, will be furnished by the Owner at cost. The Contractor must keep at the construction site at least one set of the project manual and one set of full-size drawings.

PART 4 – MATERIAL, EQUIPMENT AND WORKMANSHIP

4.01 GENERAL
Unless otherwise specifically stated in the contract documents, the Contractor must provide and pay for materials, labor, tools, equipment, water, light, power, transportation, supervision, and temporary construction of any nature, and other services, and facilities of any nature, to execute, complete, and deliver the work within the specified time. Material and equipment must be new and of a quality at least equal to that specified. Equipment offered must be current models which have been in successful regular operation under comparable conditions. This requirement does not apply to minor details, nor to thoroughly

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
64 OF 88
demonstrated improvements in design or in materials of construction. All construction work must be executed in conformity with the standard practice of the relevant trade.

4.02 PRODUCT DATA
Where required by the specifications, the Contractor must provide product data, which is a submittal furnished for information only. The information and data furnished is required by the Owner for inspecting, testing, operating, and maintaining parts of the work.

The requirements for product data are specified in Part B of the project specifications.

4.03 QUALITY
Where the contract requires that materials or equipment be provided or that construction work be performed, and detailed specifications of such materials, equipment or construction work are not set forth, the Contractor must perform the work using materials and equipment of the best grade in quality and workmanship obtainable in the market, from firms of established good reputations, and must follow standard practices in the performance of construction work. The work performed must be in conformity and harmony with the intent to secure the highest standard of construction and equipment of work as a whole and in part.

4.04 MATERIAL AND EQUIPMENT SPECIFIED BY NAME
When material or equipment is specified by reference to two or more patents, brand names, or catalog numbers, it is understood that this is referenced for the purpose of defining the performance or other salient requirements, and that other materials or equipment, of equal capacities, quality and function will be considered by the Owner upon the Contractor's request for substitution. Requests for substitution must be made in accordance with paragraph 00 72 00-4.05.

4.05 REQUESTS FOR SUBSTITUTION
The Contractor may offer material or equipment of equal or better quality and performance in substitution for those specified. The Owner will consider offers for substitution only from the Contractor and will not acknowledge or consider such offers from suppliers, distributors, manufacturers, or subcontractors. The Contractor's offers of substitution must be made in writing to the Construction Manager and must include sufficient data to enable the Construction Manager to assess the acceptability of the material or equipment for the particular application and requirements.

If the offered substitution necessitates changes to or coordination with other portions of the work, the data submitted must include drawings and details showing such changes.

Contractor agrees to perform these changes as part of the substitution of material or equipment at no additional cost to the Owner. Within 30 calendar days after receipt of the offer of substitution, the Construction Manager will review the material submitted by the

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
65 OF 88
Contractor and advise the Contractor of objections, if any, to the proposed substitution or if further information is required. Upon notification by the Construction Manager, the Contractor must either provide material or equipment that complies with project specifications or if requested, furnish additional information. Although the Construction Manager may not take any objections to the proposed substitution, that will not relieve the Contractor from responsibility for the efficiency, sufficiency, quality and performance of the substitute material or equipment, in the same manner and degree as the material and equipment specified by name. Any cost difference associated with a substitution must be reflected in the offer and the contract documents must be modified by a change order.

4.06 DEMONSTRATION OF COMPLIANCE WITH CONTRACT REQUIREMENTS A. INSPECTION:

To demonstrate Contractor’s compliance with the contract requirements, the Contractor must assist the Construction Manager in the performance of inspection work.

The Contractor must grant the Construction Manager access to the work and to the site of the work, and to the places where work is being prepared, or whence materials, equipment or machinery are being obtained for the work. The Contractor must provide information requested by the Construction Manager in connection with inspection work.

If the contract documents, laws, ordinances, or any public regulatory authority require parts of the work to be specially inspected, tested or approved, the Contractor will give the Construction Manager adequate prior written notice of the availability of the subject work for examination.

If parts of the work are covered in contravention of the Construction Manager's directive, the cost of exposing the work for inspection and closing must be borne by the Contractor regardless of whether or not the work is found to be in compliance with the contract.

If any work is covered in the absence of the Construction Manager's directive to the contrary, the Contractor must, if directed to do so by the Construction Manager, uncover, expose or otherwise make available for inspection, portions of covered work. If it is found that such work is defective, the Contractor must bear the expense of uncovering and reconstructing. If the work is found to be in compliance with the contract, the Contractor will be allowed an increase in the contract price, or an extension in the contract time, or both. A change order will be issued to document the increase, extension, or both.

B. SAMPLES OF MATERIALS:

In cases where compliance with contract requirements for materials to be incorporated in the work requires laboratory examination or special testing, the Contractor must provide samples or specimens as requested by the Construction Manager. Such samples or specimens must be provided in ample time to permit making proper test analysis and examinations before incorporating the material into the work. Tests of material will be

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
66 OF 88
conducted in accordance with the technical specifications. In the absence of a specific test requirement, the Construction Manager will determine the appropriate standard test to be used.

C. CERTIFICATION:

In cases where compliance of materials or equipment to contract requirements is not readily determinable through inspection and tests, the Construction Manager will request that the Contractor provide properly authenticated documents, certificates, or other satisfactory proof of compliance. These documents, certifications, and proofs must include performance characteristics, materials of construction and the physical or chemical characteristics of materials.

D. INSPECTION AT POINT OF MANUFACTURING:

If Owner’s inspection and testing of materials or equipment in the vicinity of the work is not practicable, the specifications may require that the inspection and testing or witnessing of tests take place at the point of manufacture. In this case and in the event the remote inspection and testing is not specified and is requested by the Owner, the required travel, subsistence, and labor expenses will be paid by the Owner. If the Contractor requests the Owner to inspect and test material or equipment at the point of manufacture, then the additional cost to the Owner for travel, subsistence, and labor expenses must be paid by the Contractor.

4.07 STORAGE OF MATERIALS AND EQUIPMENT
Materials and equipment must be stored so as to insure the preservation of their quality and fitness for the work. Stored equipment and materials must be located so as to facilitate inspection. The Contractor is responsible for damages that occur in connection with the care and protection of materials and equipment until final acceptance of the work.

4.08 MANUFACTURER'S DIRECTIONS
Manufactured articles and materials and equipment must be applied, installed, connected, erected, adjusted, tested, operated, and maintained as recommended by the manufacturer, unless otherwise specified. Manufacturer's installation instructions and procedures must be provided or obtained prior to installation of the manufactured articles, material, and equipment. Conflicts between manufacturer’s installation instructions and these specifications require the Contractor to make a request for information (RFI).

4.09 DEFECTIVE WORK
A. CORRECTION OF DEFECTIVE WORK:

When, and as often as the Construction Manager determines through his or her inspection procedures to be the case, material, equipment or workmanship incorporated in the project do not meet the requirements of the contract, the Construction Manager will give

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
67 OF 88
written notice of the noncompliance to the Contractor. Within five days from the receipt of the notice, the Contractor must undertake the work necessary to correct the deficiencies, and to comply with the contract. If the Contractor disagrees with the Construction Manager's determination and believes that the corrective work should be covered by a change order, the Contractor must immediately notify the Owner's Representative, in writing, setting forth the Contractor’s position. Within five days after receipt of the Contractor's notification, the Owner's Representative will review the matter and notify the Contractor, in writing, of his or her determination. If the Owner's Representative determines that the corrective work is required to comply with the contract, the Contractor must proceed with that work. As a condition precedent to the Contractor's request for either additional compensation or time extension, or both, resulting from the performance of the corrective work, the Contractor must, within 15 calendar days after receipt of the Owner's Representative's determination, notify the Owner's Representative in writing of the Contractor’s intent to claim additional compensation, time or both. The Contractor must document the cost information associated with the corrective work with daily records in accordance with paragraph 00 72 00-7.02 F and provide that information to the Construction Manager monthly. Receipt of the cost data by the Construction Manager will not be construed to be an acceptance of the corrective work, or an authorization for a change order to cover the corrective work.

B. RETENTION OF DEFECTIVE WORK:

Prior to acceptance of the project, the Owner may, at its option, retain work which is not in compliance with the contract if the Owner determines that such defective work is not of sufficient magnitude or importance to make the work dangerous or undesirable. The Owner also may retain defective work, if, in the opinion of the Construction Manager, and with concurrence of the Owner's Representative, removal of that work is impractical or will create conditions that are dangerous or undesirable. Just and reasonable value for such defective work will be judged by the Owner and appropriate deductions will be made in the payments due, or to become due to the Contractor. Final acceptance does not act as a waiver of the Owner's right to recover from the Contractor an amount representing the deduction for retention of defective work.

4.10 GUARANTEE
The guarantee period is 365 days from the Notice of Completion. During the guarantee period, the Contractor must, upon the receipt of notice in writing from the Owner, promptly make all repairs arising out of defective materials, workmanship or equipment. The Owner is hereby authorized to make such repairs, if ten days after giving of such notice to the Contractor, the Contractor has failed to make or undertake the repairs with due diligence.

In case of an emergency where, in the opinion of the Owner, delay could cause serious loss or damage, repairs may be made without notice to the Contractor and the expenses in connection with those repairs are chargeable to the Contractor.

For the purpose of this paragraph, "acceptance of the work" means the acceptance of the project by the Owner, in accordance with paragraph 00 72 00-7.07. "Acceptance of the work" does not extinguish any covenant or agreement on the part of the Contractor to

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
68 OF 88
be performed or fulfilled under this contract that has not, in fact, been performed or fulfilled at the time of such acceptance. All covenants and agreements continue to be binding on the Contractor until they have been fulfilled.

The Owner and the Contractor agree that guarantee on the equipment possessed and used by the Owner in accordance with paragraph 00 72 00-7.06 will commence on the date that the Owner takes possession of the equipment and so notifies the Contractor in writing. Owner and Contractor further agree that such taking possession and use will not be deemed as substantial completion or acceptance of any part of the work. Takeover of equipment will be at the Owner's option and will not be made until the equipment can be put into routine service on a permanent basis.

PART 5 – LIABILITY AND INSURANCE

5.01 LIABILITY OF CONTRACTOR
The Contractor is liable for any and all losses or damages from whatever cause that, prior to final acceptance, may occur on or to any part of the work. The Contractor is not liable for losses or damages caused solely by the act of the Owner.

The Contractor is liable for damages and injury to persons owning property, on or in the vicinity of the work, or which occur to a person, persons, or any property whatsoever, arising out of the Contractor's performance of this contract. The Contractor's liability is not dependent upon whether or not such damage or injury be caused by the negligence of the Contractor, and whether or not such damage or injury is caused by the inherent nature of the work as specified.

The Contractor must indemnify and hold the Owner, the Construction Manager, the design engineer, and their officers, principals, agents, subcontractors, and employees, harmless from any and all loss, defense cost, expense, claims, demand or liability whatsoever, arising from allegations of injuries to persons or damage to property related to the performance of this contract, regardless of concurrent negligence on the part of such indemnitees. This indemnification obligation is not limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for the Contractor or any subcontractor under workers compensation acts, disability benefit acts, or another employee benefit act.

In case any suit or legal proceeding is brought against the Owner, the Construction Manager, the design engineer, or their officers, principals, agents, subcontractors, or employees, on account of loss or damage sustained by person, or persons, or property, as a result of the performance of the work covered by this contract, the Contractor agrees to assume the cost of defense of that action, and to pay the expenses connected therewith, and the judgments that may be obtained against the Owner, the Construction Manager, the design engineer, or their officers, principals, agents, subcontractors, or employees, in such suits. In the event that a lien is placed against the property of the Owner, the Construction Manager, the design engineer, or their officers, principals, agents, subcontractors, or

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
69 OF 88
employees, as a result of such suits, the Contractor agrees immediately to cause the same to be dissolved and discharged by giving bond or otherwise. This agreement to defend and to pay the related expenses exists whether or not the alleged injuries or damage are due to the negligence of the Contractor, and whether or not the alleged injuries or damage are caused by the inherent nature of the work, as specified.

The mention of specific duties or liabilities imposed on the Contractor are not a limitation or restriction of general duties or liabilities imposed upon the Contractor by the contract. Reference to specific duties or liabilities is made herein, merely for the purpose of explanation.

5.02 BONDS
The Contractor must provide two bonds, each in the amount of 100 percent of the contract price. One bond will serve as security for the faithful performance of the work and the other as security for the faithful payment and satisfaction of the persons furnishing materials and performing labor on the work. The bonds must be issued by a corporation duly and legally licensed to transact surety business in the State of California. The two bonds must remain in force throughout the period required to complete the work, and thereafter for a period of 365 calendar days after final acceptance of the work. The bonds must be executed by a duly licensed surety company that is listed in the latest Circular 570 of the United States Treasury Department as being acceptable as surety on federal bonds.

No surety's liability on the bonds may exceed the underwriting limitations for the respective surety specified in Circular 570. The scope of the bonds or the forms thereof prescribed in these contract documents in Sections 00 61 05 and 00 61 10 in no way affect or alter the liabilities of the Contractor to the Owner.

5.03 INSURANCE
A. GENERAL:

1. EVIDENCE OF INSURANCE: Prior to execution of the contract, the Contractor must file, with the Owner, evidence of insurance from the insurer, certifying to the coverage of the insurance required herein. The evidence of insurance must be certified by a properly authorized officer, agent, general agent, or qualified representative of the insurer, and must certify the names of the insured, the type and amount of insurance, the location and operations to which the insurance applies, and the expiration date. The evidence must include the agreement of the insurer to give, by certified mail, notice to the Owner at least 30 calendar days prior to the effective date of cancellation, lapse, or material change in the policy.

This Certificate of Insurance is not an insurance policy and does not amend, extend, or alter the coverage afforded by the policies listed herein. Notwithstanding any requirement, term, or condition of the contract with respect to which this certificate is issued, the insurance afforded by the policies described herein is subject to the terms, exclusions, and conditions of such policies.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
70 OF 88

2. CANCELLATION OF INSURANCE: The Contractor must deliver to the Owner policies of insurance and the receipts for payment of premiums thereon. Should the Contractor neglect to obtain and maintain in force such insurance and deliver such policy or policies and receipts to the Owner, then Owner may obtain and maintain such insurance.

The Contractor hereby appoints the Owner as its true and lawful attorney, to do the things necessary for this purpose. Money expended by the Owner under the provisions of this paragraph for insurance premiums will be charged to the Contractor. Failure of the Owner to obtain such insurance in no way relieves the Contractor of his responsibilities under this contract.

3. ACCEPTABILITY OF INSURERS. Insurance is to be placed with insurers authorized to conduct business in the State of California with a current A.M. Best rating of no less than A: VII, unless otherwise approved by the Owner.

B. MINIMUM SCOPE AND LIMIT OF INSURANCE:

4. Contractor hereby agrees to waive rights of subrogation which any insurer of Contractor may acquire from Contractor by virtue of the payment of any loss.

Contractor agrees to obtain any endorsement that may be necessary to affect this waiver of subrogation. The Workers’ Compensation policy shall be endorsed with a waiver of subrogation in favor of the Owner for all work performed by the Contractor, its employees, agents, and subcontractors.

PART 6 – PROGRESS AND COMPLETION

6.01 NOTICE TO PROCEED
After execution of the contract by the Owner, written notice to proceed will be given by the Owner to Contractor. Notwithstanding other provisions of the contract, the Contractor is not obligated to perform work and the Owner is not obligated to accept or pay for work performed by the Contractor prior to date of the notice to proceed. The Owner's knowledge of work being performed prior to date of the notice to proceed does not obligate the Owner to accept or pay for such work.

6.02 CONTRACT TIME
A. GENERAL:

Time is of the essence of the contract. The Contractor must promptly start the work after the date of the notice to proceed and must prosecute the work so that the project is complete within the time specified in paragraph 1.01 of Section 01 21 43 “Time Allowances”.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
72 OF 88
During periods when weather or other conditions are unfavorable for construction, the Contractor will pursue only such portions of the work as will not be damaged thereby. No portions of the work where acceptable quality or efficiency will be affected by unfavorable conditions may be constructed while those conditions exist. It is expressly understood and agreed by and between the Contractor and the Owner that the contract time for completion of the work is reasonable, taking into consideration the average climatic and economic conditions and other factors prevailing in the locality of the work.

B. CONSTRUCTION SCHEDULE:

The Contractor must provide a construction schedule and reports for scheduling and coordinating the work within the contract time. Contract time extensions must be incorporated into updated schedules, reflecting their effect at the time of occurrence. Failure of the Contractor to comply with these requirements for submittal of the construction schedule and reports may be cause for delay in review of progress payments by the Construction Manager.

C. CONSTRUCTION PROGRESS:

The Contractor must furnish such manpower, materials, facilities, and equipment as may be necessary to insure the prosecution and completion of the work in accordance with the accepted schedule. If work falls behind the accepted construction schedule, the Contractor agrees that he will take some or all of the following actions to return the project to the accepted schedule. These actions may include the following:

1. Increase manpower in quantities and crafts;

2. Increase the number of working hours per shift, shifts per working day, working days per week, or the amount of equipment, or any combination of the foregoing; and/or

3. Reschedule activities.

If requested by the Construction Manager, the Contractor must prepare a proposed schedule revision demonstrating a plan to make up the lag in progress and insure completion of the work within the contract time. The proposed revision must be submitted to the Construction Manager in accordance with Section 01 33 00. Upon receipt of an acceptable proposed schedule, the revision to the construction schedule must be made in accordance with Section 01 33 00 Paragraph 4. All actions to return the project to the accepted schedule are at the Contractor's expense.

The Contractor must pay all costs incurred by the Owner that result from the Contractor's action to return the project to its accepted schedule. Contractor agrees that Owner may deduct such charges from payments due the Contractor. It is further understood and agreed that none of the services performed by the Construction Manager in monitoring, reviewing, and reporting project status and progress operate to relieve the Contractor of

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
73 OF 88
responsibility for planning and managing construction work in conformance with the construction schedule.

D. DELAYS:

1. NOTICE OF DELAYS: When the Contractor foresees a delay in the prosecution of the work and, in any event, immediately upon the occurrence of a delay that the Contractor regards as unavoidable, he or she must notify the Construction Manager in writing of the probability of the occurrence of the delay, the extent of the delay, and its probable cause. The Contractor must take immediate steps to prevent, if possible, the occurrence or continuation of the delay. If this cannot be done, the Construction Manager must determine how long the delay is likely to continue and to what extent the prosecution and completion of the work are being delayed. The Construction Manager must also determine whether the delay is to be considered avoidable or unavoidable and notify the Contractor of his or her determination. The Contractor agrees that no claim is allowed for delays the causes of which are not called to the attention of the Construction Manager at the time of their occurrence or as soon thereafter as Contractor becomes aware of them.

2. AVOIDABLE DELAYS: Avoidable delays in the prosecution of the work include delays that could have been avoided by the exercise of care, prudence, foresight, and diligence on the part of the Contractor or its subcontractors. Avoidable delays include:
a. Delays which may in themselves be unavoidable, but which affect only a portion of the work and do not necessarily prevent or delay the prosecution of other parts of the work nor the completion of the whole work within the contract time.
b. Time associated with the reasonable interference of other contractors employed by the Owner which do not necessarily prevent the completion of the whole work within the contract time.

3. UNAVOIDABLE DELAYS: Unavoidable delays in the prosecution or completion of the work include delays that result from causes beyond the control of the Contractor and could not have been avoided by the exercise of care, prudence, foresight, and diligence on the part of the Contractor or its subcontractors. Delays in completion of the work of other contractors employed by the Owner will be considered unavoidable delays insofar as they interfere with the Contractor's completion of the work. Delays due to normal weather conditions are not regarded as unavoidable because the Contractor agrees to plan its work with prudent allowances for interference by normal weather conditions. Delays caused by Acts of God, fire, unusual storms, floods, tidal waves, earthquakes, strikes, labor disputes, freight embargoes and shortages of materials are considered unavoidable delays if they prevent the Contractor from proceeding with at least seventy-five percent (75%) of the normal labor and equipment force for at least five hours per day toward completion of the current controlling item on the accepted critical path schedule.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
74 OF 88
If abnormal conditions prevent the work from beginning at the usual starting time, or prevent the Contractor from proceeding with seventy-five percent (75%) of the normal labor and equipment force for a period of at least five hours per day, and the crew is dismissed as a direct consequence, Contractor will not be charged for a working day whether or not conditions change so that the major portion of the day could be considered to be suitable for work on the controlling item.

E. EXTENSION OF TIME:

1. AVOIDABLE DELAYS: If the work is not completed in the accepted construction schedule, including any extension of time that may have been granted for unavoidable delays, the Contractor will be assessed damages for those costs incurred by the Owner that are attributable to the fact that the work was not completed on schedule.

The Owner may grant an extension of time for avoidable delay if he or she deems it in its best interest. If the Owner grants an extension of time for avoidable delay, the Contractor agrees to pay actual costs, including charges for engineering, inspection, and administration, as specified in Section 00 72 00 Paragraph 7.04, incurred during the extension.

2. UNAVOIDABLE DELAYS: For delays that the Contractor considers to be unavoidable, he must submit to the Construction Manager complete information demonstrating the effect of the delay on the controlling operation in the accepted construction schedule. The submission must be made within 30 calendar days of the occurrence that is claimed to be the cause of the unavoidable delay. The Construction Manager will review the Contractor's submission and determine the number of days of unavoidable delay and the effect of any unavoidable delay on controlling operations of the work. The Owner agrees to grant an extension of time to the extent that unavoidable delays affect controlling operations in the construction schedule. During such extension of time, neither extra compensation, nor engineering inspection and administration, nor damages for delay will be charged to the Contractor. It is understood and agreed by the Contractor and Owner that time extensions due to unavoidable delays will be granted only if such unavoidable delays involve controlling operations which would prevent completion of the whole work within the specified contract time.

3. LIQUIDATED DAMAGES: It is agreed by the parties to the contract that in case all the work called for under the contract in all parts and requirements is not finished or completed within the number of calendar days as set forth in Section 01 21 43 “Time Allowances,” damage will be sustained by the Owner, and that it is and will be impracticable and extremely difficult to ascertain and determine the actual damage which the Owner will sustain in the event of and by reason of the delay; and it is therefore agreed that the Contractor will pay to the Owner, the sum of One Thousand dollars ($1,000.00) per day for each and every calendar day's delay in finishing the work in excess of the number of working days prescribed; and the Contractor agrees to pay the liquidated

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
75 OF 88
damages herein provided for, and further agrees that the Owner may deduct the amount thereof from any moneys due or that may become due the Contractor under the contract.

6.03 SUSPENSION PROCEDURES
The Owner may, at its convenience and at any time and without cause, suspend, delay, or interrupt all or any part of the work for a period of not more than 90 days by notice in writing to the Contractor. The Owner must specify the date on which the work must be resumed. The work must be resumed by the Contractor within 10 days after receiving written notice from the Owner to do so. The Contractor will be allowed an increase in the contract price or an extension of contract time, or both, directly attributable to any suspension if he makes a claim therefore as provided in the paragraphs related to change of contract price and change of contract time.

6.04 DEFAULT PROCEDURES
A. EVENTS OF DEFAULT:

The Owner may declare the Contractor in default of the contract if any one or more of the following events occurs:

1. Contractor is bankrupt or insolvent.

2. Contractor makes a general assignment for the benefit of creditors.

3. A trustee or receiver is appointed for Contractor, or for any of Contractor's property.

4. Contractor files a petition to take advantage of any debtor's act, or to reorganize under any bankruptcy chapter or law.

5. Contractor repeatedly fails to make prompt payments to subcontractors or others for labor, materials, or equipment.

6. Contractor disregards laws, ordinances, rules, regulations, or orders of any public body having jurisdiction.

7. Contractor disregards the authority of Construction Manager.

8. Contractor violates in any substantial way the provisions of the contract documents by failing, neglecting, or refusing to proceed according to and in full compliance with the provisions and covenants of the contract documents.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
76 OF 88
B. NOTICE OF DEFAULT AND OPPORTUNITY TO CURE:

In the event the Owner declares the Contractor be in default, the Owner will must give written notice of default to the Contractor’s Representative either personally or by certified mail to the business address of the Contractor. Notice will be given as of the date of personal service or the date of delivery of the certified mail. Except for emergencies, the Contractor will have ten (10) days to cure the default after the date of the notice. If the default cannot be reasonably cured within ten (10) days, then Contractor must commence to cure the breach within ten (10) days and diligently and continuously prosecute such cure to completion within a reasonable amount of time, which in no event may be later than twentyone (21) days after receipt of the notice.

C. REMEDIES FOR DEFAULT:

In the event that the Contractor fails to cure any default declared by Owner within the time period set forth above, then the Owner may pursue any remedies available under law or equity, including, without limitation, the following:

1. Invoke Performance Bond. The Owner may, with or without terminating the contract and reserving to itself all rights to damages related thereto, exercise its right under the performance bond.

2. Suspend the Contract. The Owner may, without terminating the contract and reserving to itself all rights to damages related thereto, suspend all or any portion of this contract for as long a period of time as the Owner determines, in its sole discretion, appropriate, in which event the Owner will have no obligation to adjust the contract price or contract time, and will have no liability to Contractor for damages if the Owner directs Contractor to resume work.

3. Perform and Withhold. The Owner may, without terminating the contract, engage others to perform the work or portion of the work that has not been performed by Contractor and withhold the cost thereof to the Owner from future payments to Contractor, reserving to itself all rights to damages related thereto.

4. Delete Certain Services. The Owner may, without terminating the contract, delete certain portions of the work, reserving to itself all rights to damages related thereto.

5. Terminate the Contract. The Owner may terminate all or any part of this contract for default in accordance with the provisions below, reserving to itself all rights to damages related thereto.

6. Additional Provisions. All of Owner’s rights and remedies under this contract are cumulative and in addition to those rights and remedies

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
77 OF 88
available in law or in equity. Designation in the contract of certain breaches as material may not be construed as implying that other breaches not so designated are not material nor may such designations be construed as limiting Owner’s right to terminate the contract, or the exercise of its other rights or remedies for default, to only material breaches. Owner’s determination of whether there has been noncompliance with the contract so as to warrant exercise by Owner of its rights and remedies for default under the contract, will be binding on all parties. No termination or action taken by Owner after such termination will prejudice any other rights or remedies of Owner provided by law or equity or by the contract upon such termination; and Owner may proceed against Contractor to recover all damages, liquidates or otherwise, suffered by Owner.

6.05 TERMINATION PROCEDURES
A. TERMINATION FOR DEFAULT:

1. The Owner may terminate the contract upon 7 days’ written notice to Contractor and to Contractor’s surety whenever the Contractor is declared to be in default and fails to timely cure the default. Notice will be given as of the date of personal service or the date of delivery of the certified mail.

2. After termination of the contract for default, the Owner may exclude the Contractor from the site and take possession of the work and all of the Contractor's tools, appliances, construction equipment, and machinery at the site and use the same to the full extent they could be used by the Contractor. The Owner may incorporate in the work all materials stored at the site or for which the Owner has paid the Contractor and that are stored elsewhere. In such case, the Contractor is not entitled to receive any further payment until the work is finished.

3. If the unpaid balance of the contract price exceeds the direct and indirect cost of the completed work, including compensation for additional professional services, the excess must be paid to the Contractor. If such costs exceed such unpaid balance, the Contractor must pay the difference to the Owner. The costs incurred by the Owner will be verified by the Construction Manager and incorporated into a change order, but in finishing the work, the Owner will not be required to obtain the lowest figure for work performed.

4. Where the Contractor's services have been so terminated by the Owner, the termination does not affect any rights of the Owner against the Contractor for damages then existing or that may thereafter accrue.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
78 OF 88
Any retention or payment of monies due the Contractor by the Owner will not release the Contractor from liability for said damages.

5. If the Owner terminates this contract for default, and it is thereafter determined that the Contractor had not failed to perform its obligations or defaulted in any way, the termination will then be deemed to have been effected for the convenience of the Owner. In that event, any adjustment of compensation to Contractor must be in accordance with paragraph 00 72 00-6.05 B.

B. TERMINATION BY OWNER FOR OTHER THAN DEFAULT:

1. The Owner may, without prejudice to any other remedy it may have under the provisions of the contract, terminate this contract, in whole or in part, at any time by giving written notice to Contractor or its representative either personally or by certified mail. Termination is effective upon receipt of the notice by Contractor. Contractor must immediately discontinue work and take all reasonable steps with its suppliers and subcontractors to minimize cancellation charges and other costs.

2. In the event of termination for reasons other than default of Contractor, Contractor is entitled to recover all reasonable costs incurred in connection with performance of the work, plus any cost and expense reasonably and necessarily incurred in connection with the termination, plus a percentage of the profit based on the percentage of completion of the work.

C. TERMINATION BY CONTRACTOR:

If the work is stopped by order of a court, a public authority, or the Owner for a period of 90 calendar days or more, through no act or fault of the Contractor or anyone employed by him or his subcontractors, then the Contractor may terminate the contract upon 10 calendar days’ written notice to the Owner either by personal delivery or certified mail, effective upon receipt. The Owner must implement procedures as set forth in paragraph 00 72 00-6.05 B.

PART 7 – MEASUREMENT AND PAYMENT

7.01 PAYMENTS TO CONTRACTOR
A. BREAKDOWN OF CONTRACT PRICES:

If the Contractor disagrees with the Measurement and Payment section of Part B and except in cases where unit prices form the basis for payment under the contract, the Contractor must, within 20 days of receipt of the notice to proceed, submit a breakdown of

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
79 OF 88
the contract price showing the value assigned to each part of the work including an allowance for profit and overhead. In submitting the breakdown, the Contractor certifies that it is not unbalanced and that the value assigned to each part of the work represents its estimate of the actual cost, including profit and overhead, of performing that part of the work.

The breakdown must be sufficiently detailed to permit its use by the Construction Manager as one of the bases for evaluating requests for payment.

B. PROJECT STATUS REVIEW:

Contractor and Construction Manager will meet each month prior to the Contractor submitting the progress payment request for the previous month. The purpose of the meeting is to review project status in relation to the construction schedule; review value of work completed during the previous month; and, if applicable, review Contractor's plans to return project status to that required by the schedule. Within 5 days following this meeting, the Contractor must submit a written progress report comprising:

1. A copy of the current construction schedule marked up to indicate percent complete, actual completion or start dates since the previous review, and the estimated remaining duration for each activity in progress.

2. Reasons any activities are behind schedule and a description of the corrective steps being taken.

C. PROGRESS PAYMENTS:

1. PAYMENT REQUEST PROCEDURES: By the 5th day of each
month, the Contractor must submit to the Construction Manager a partial-payment estimate, filled out and signed by the Contractor, covering acceptable work performed during the previous month or since the last partial payment estimate was submitted. If requested by the Construction Manager, the Contractor must provide additional data to support the payment estimate. Additional data may include satisfactory evidence of payment for equipment, materials, and labor including payments to subcontractors and suppliers.

Requests for payment for delivered equipment and material must be accompanied by certified invoices by the suppliers. Such equipment and material must be suitably and safely stored at the site of the work.

2. REVIEW PROCEDURES: Within 7 days after receipt of the partial payment estimate, the Construction Manager will review the estimate and either (a) indicate in writing to the Owner's Representative his or her concurrence with the estimate and the Construction Manager’s recommendation that payment be made or (b) indicate in writing to the Contractor his or her reasons for not concurring with the estimate. If the Construction Manager recommends payment and the Owner's Representative concurs, the Owner will, within 30 calendar days after receipt of the Construction Manager's recommendation, pay the Contractor a progress payment on the basis of the approved partial-payment estimate.

The payments will take into account the retention provisions provided for herein.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
80 OF 88
In the event the Construction Manager does not concur with the estimate, the Contractor may make the changes necessary to obtain the Construction Manager's concurrence and resubmit the partial-payment estimate or submit the original progresspayment estimate directly to the Owner's Representative, indicating in writing his or her reasons for refusing to make the changes necessary to obtain concurrence.

3. RETENTION: The Owner will retain a percentage of each payment except as specified below, in accordance with Public Contract Code Section 7201. The retained amount is available for the protection and payment of the person, or persons, mechanics, subcontractors, or material men who perform labor or work under the contract, and persons who supply such person, persons or subcontractors with components and supplies for carrying on such work.

The Owner will retain five (5) percent of each progress payment.

Under no circumstances may any provision of this section be construed to limit the ability of the Owner to withhold 150 percent of the value of any disputed amount of work from the final payment, as provided for in Section 7107 of the Public Contract Code. In the event of a good faith dispute, nothing in this section may be construed to require the Owner to pay for work that is not approved or accepted in accordance with the proper plans or specifications.

4. WITHHOLDING: The Construction Manager may refuse to
recommend the whole or any part of any payment if, in the Construction Manager's opinion, it would be incorrect to make such recommendation to the Owner. The Construction Manager may also refuse to recommend any payment, or because of subsequently discovered evidence or the result of any tests, may nullify any payment previously recommended to such extent as may be necessary in the Construction Manager's opinion to protect the Owner from loss as a result of:
a. Defective or damaged work.
b. A deductive change order.
c. Persistent failure of the Contractor to perform the work in accordance with the contract documents, including failure to maintain the progress of the work in accordance with the construction schedule. Persistent failure to maintain the progress of the work means that for a period of two consecutive months following a written notice from the Construction Manager, the Contractor fails to correct a behind-schedule condition at a rate that would reasonably indicate that he will finish the project on schedule.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
81 OF 88
d. Disregard of authority of the Construction Manager or the laws of any public agency having jurisdiction.
e. Failure to submit required Labor Compliance documentation for the Contractor and/or subcontractor(s).

The Owner may refuse to make payment of the full amount recommended by the Construction Manager because of claims made against the Owner on account of Contractor's performance or furnishing of the work or because liens have been filed in connection with the work or because there are other items entitling Owner to reduce the amount recommended. In such case, the Owner will give Contractor prompt written notice with a copy to the Construction Manager stating the reasons for each action.

3. STOP PAYMENT NOTICES: The Owner, by and through the
Construction Manager or other authorized officers, may at its option and at any time retain out of any amounts due the Contractor, sums sufficient to cover claims filed pursuant to Section 3179, et seq., of the Civil Code of the State of California.

4. PROMPT PAYMENT: Contractor understands and agrees that Owner is relying on progress payments from City of Crescent City and Bureau of Reclamation to provide the funds for payment of Contractor progress payment requests.

Owner has been advised that it may take 45-60 days for such progress payments to be received by Owner. Owner understands that the payment requirements of Public Contracts Code Section 20104.50 apply, and that interest will be payable upon request of Contractor on progress payments made after the 37th day after Owner receipt of the proper payment request from Contractor.

D. FINAL PAYMENT:

On the condition that no liens or claims are outstanding, and all required labor compliance documentation has been received to the satisfaction of the City, Owner will make final payment to the Contractor in the manner provided by law following the expiration of 35 calendar days after acceptance of the work and filing of the notice of completion by the Owner. Final payment must include the entire sum found to be due under this contract after deducting previous payments and such other lawful amounts as the terms of this contract describe. Prior estimates and payments, including those relating to extra work or work omitted, are subject to correction by the final payment.

Acceptance by the Contractor of final payment acts as a release to the Owner of all claims by and all liability to the Contractor other than claims in stated amounts that may be specifically excepted by the Contractor for things done or furnished in connection with this work and for every act and neglect of the Owner and others relating to or arising out of this work. Payment by the Owner does not release the Contractor or its surety from any obligation under the contract or under the performance bond and payment bonds.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
82 OF 88

7.02 CHANGE ORDERS
A. GENERAL:

The Owner may, at any time, without notice to the sureties, by written order designated or indicated to be a change order, make any change in the work within the general scope of the contract, including but not limited to the following changes:

1. In the specifications (including drawings and designs).

2. In the method or manner of performance of the work.

3. In the Owner-furnished facilities, equipment, materials, services, or site.

4. Directing acceleration in the performance of the work.

Any other written order or an oral order (which terms as used in this paragraph include direction, instruction, interpretation, or determination) from the Owner, that causes any such change, must be treated as a change order under this clause, if the Contractor gives the Owner written notice stating the date, circumstances, and source of the order and if the Contractor regards the order as a change order.

Except as provided in this clause, no order, statement, or conduct of the Owner is or may be treated as a change order under this clause nor does it entitle the Contractor to an equitable adjustment.

If any change under this clause causes an increase or decrease in the Contractor's cost of, or the time required for, the performance of any part of the work under this contract, whether or not changed by any order, an equitable adjustment must be made and the contract modified in writing accordingly. However, except for claims based on defective specifications, claims will not be allowed for any costs incurred more than 20 days before the Contractor gives written notice as required. Also, in the case of defective specifications for which the Owner is responsible, the equitable adjustment includes any increased cost reasonably incurred by the Contractor in attempting to comply with such defective specifications.

If the Contractor intends to assert a claim for an equitable adjustment under this clause, the Contractor must, within 30 days after receipt of a written change order or the furnishing of a written notice, submit to the Owner a written statement setting forth the general nature and monetary extent of such claim, unless the Owner extends this period.

The statement of claim hereunder may be included in the notice.

A claim by the Contractor for an equitable adjustment will not be allowed if it is asserted after final payment under this contract.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
83 OF 88
B. EXTRA WORK:

Extra work means providing materials and equipment and performing work not directly or by implication called for by the contract. Changes in measured quantity under a unit price contract or item are not extra work. If the Owner requires extra work, the Owner may (1) do it itself, (2) employ others to do it, (3) direct the Contractor to perform the extra work at unit bid price or a combination of such items, (4) direct the Contractor to perform the extra work at a mutually agreed upon lump sum, or (5) direct the Contractor to perform the extra work on a time and expense basis.

C. OMITTED WORK:

The Owner may, by written order to the Contractor, omit work, equipment, and material to be provided under the contract, and the value of the omitted work, equipment and material will be deducted from the contract price. The deducted value will be a lump sum or unit bid price agreed upon in writing by the Contractor and Owner based on the breakdown and cost information submitted by the Contractor.

D. UNIT BID PRICE CHANGE:

Increases or decreases in the quantity of a contract item of work that was bid on a unit basis will be made by comparing the total pay quantity of such item of work with the Construction Manager's estimate. When changes in quantities exceed 25 percent of the original bid quantity and the total dollar change of that bid item is significant, the Owner will review the unit price to determine if a new unit price should be negotiated. Methods for Changed Quantity Payment Adjustments shall be those specified in the Caltrans Standard Specifications, latest edition
E. LUMP SUM CHANGES:

Whenever the Contractor is directed to perform extra work on a lump-sum basis, changes in contract price resulting from the extra work will be based on a mutually agreed upon lump-sum price. The Contractor's proposal for such changes must include a detailed breakdown of labor and materials costs for the extra work to be performed by its forces and the forces of its subcontractors or material suppliers as may be required. The breakdown must include any labor surcharge and any sales- or use-tax cost. Whenever the Owner requests that the Contractor prepare a lump-sum price in connection with a change order, the Contractor is entitled to the costs incurred in the preparation of that price whether or not the lump-sum amount is finally accepted by the Owner. Those costs will be incorporated in the lump-sum amount.

Compensation for the extra work will be based on the direct costs as listed in the detailed proposal, plus a mutually agreed upon percent of direct costs for overhead and profit, plus one percent (1%) of those direct costs for bond. The allowance for overhead and profit must include full compensation for overhead, including superintendence, and

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
84 OF 88
additional overhead attributable to a time extension granted because of the change order and no separate charge may be made for overhead.

When the change order involves work omitted, the reduction of the contract price will be based on the direct costs listed in the detailed proposal submitted by the Contractor. An additional reduction may be made of an amount that is identified as reduced overhead costs attributable to the work omitted. No reduction will be made for profit originally attributable to the omitted work.

F. TIME AND EXPENSE CHANGES:

1. GENERAL: Whenever the Contractor is directed to perform extra work on a time and expense basis, the Contractor must maintain accurate records. Each day a record of labor, materials, and equipment costs will be submitted to the Construction Manager for verification. These records will reflect the actual and necessary expenses pertaining to the extra work and will be available for audit. Audits conducted under this provision must be in accordance with generally accepted auditing standards and established procedures and guidelines of the reviewing or audit agency(ies).

Payment to the Contractor for extra work performed on a time-and-expense basis will consist of the actual necessary expense for doing the extra work, plus an allowance of 15 percent of labor, material and equipment rental for overhead, general superintendence, and profits, plus one percent (1%) of those direct costs for bond. This basis of payment applies to work done directly by the Contractor and to work done by a subcontractor, except the one percent (1%) allowance for bond does not apply to work performed by a subcontractor. When the work is done by a subcontractor, the Contractor may add five percent (5%) to the subcontractor's charges to cover overhead and profit and one percent (1%) for bond.

In determining time-and-expense compensation, the term "actual necessary expense" means the sum of (1) materials and equipment, (2) labor, (3) supervision, (4) construction equipment, (5) professional services, and (6) other costs. “Charges” for such items means the actual cost whether incurred by the Contractor, a subcontractor or others.

The items making up "actual necessary expense" are defined as follows:

2. MATERIALS AND EQUIPMENT: Materials and equipment means costs for materials and equipment provided by the Contractor and necessarily used in the work includes applicable taxes.

3. LABOR: The cost of labor will be the sum of actual wages paid, labor surcharge, and subsistence and travel allowances. Actual wages paid include employer payments to or on behalf of the worker for health and welfare, pension, vacation, and similar purposes. The labor surcharge includes applicable labor-related taxes, Workers Compensation Insurance premiums, public liability and property damage insurance premiums, and other legally required costs directly related to labor. Where subsistence and

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 00
85 OF 88
travel allowance are required for performance of extra work, the charges include the actual amount paid to each worker for these items.

4. SUPERVISION: If, in the Owner's judgment, full-time supervision of the extra work is required, it will be authorized in writing by the Construction Manager and charges for that supervision will be included as an actual necessary expense. Charges for supervision of the extra work by the Contractor's representative are not part of actual necessary expense.

5. CONSTRUCTION EQUIPMENT: Charges for the use of construction equipment required in the performance of extra work will be based on rental rates set forth in the State of California then-current official published document covering rental of equipment used on force account work. For equipment not listed in that document, the rental rate will be as listed by the local section of the Associated General Contractors. If the equipment is not listed by the Associated General Contractors, the rental rate will be mutually agreed upon in writing between the Contractor and Owner prior to the use of the unlisted equipment. The reasonable cost of moving equipment onto and off the job site will be included, but equipment rental will not be paid when the equipment is inoperative due to breakdowns. Individual pieces of equipment or small tools having a replacement value of $100 or less are considered expendable and no payment will be made for these.

7.05 SUBSTANTIAL COMPLETION
The Contractor, on considering the work to be substantially complete and ready for its intended use, must so notify the Construction Manager in writing. The notification must include an itemized list of remaining incomplete work. If the Construction Manager determines that the work is not substantially complete, he will so notify the Contractor in writing identifying the reasons for such a determination. If the Construction Manager finds the work substantially complete, he will meet with the Contractor to; (1) prepare a punch list of incomplete items of work; (2) define the division of responsibility between Owner and Contractor with respect to security, operation, maintenance, utilities, insurance, and warranties; and (3) describe any other issues related to acceptance of the substantially completed work. Upon reaching agreement with the Contractor, the Construction Manager will write to the Owner, certifying that the work is substantially complete, listing the items of incomplete work, stating the date for completion of incomplete work, defining the division of responsibilities, and setting forth any other terms related to acceptance.

The Owner, who has sole discretion for determination of substantial completion, will review the Construction Manager's certification that the work is substantially complete and concurring with that certification, will notify the Contractor, in writing, that the work is accepted as substantially complete. Except for any portion(s) of work specified for early completion or required by the Owner for early possession (paragraph 00 72 00-7.06), substantial completion will not occur for any work until the entire project is ready for possession and use. The acceptance notice will include a punch list of incomplete work items, set the date for their completion, describe the division of responsibility between the Owner and Contractor, and describe any other terms of acceptance.

7.06 POSSESSION OF PORTIONS OF THE PROJECT
Should the Contractor fail to meet any date specified for substantial completion of the work or any portion of the work requiring early possession and use by the Owner, the Owner may, after a 10-day written notice to the Contractor, take over such portion or all of the work that is behind schedule. In such case, the Construction Manager will prepare a punch list of incomplete work. The Owner may allow the Contractor reasonable access to the work at such times that the operation of the project will not be affected or that the Contractor may complete the work his or herself after giving the Contractor notice of its intention to do so.

The cost of Owner's work will be charged to and deducted from amounts due to the Contractor. The substantial completion date will be established as the date when the Owner actually begins using the project or portion of the project for its intended purpose. Division of responsibilities between Owner and Contractor, beginning of warranties, and any other issues relating to substantial completion will be as specified in paragraph 00 72 00-7.05.

7.07 ACCEPTANCE OF THE PROJECT
Upon completion of the work, including portions of the work previously accepted as substantially complete, the Contractor must notify the Construction Manager, in writing, that the work is complete. Upon receipt of the notification, the Construction Manager will determine if the work conforms to the terms of the contract. If the Construction Manager finds materials, equipment, or workmanship that do not meet the terms of the contract, then the Construction Manager will prepare a punch list of non-conforming items and submit it to the Contractor. Following completion of the corrective work by the Contractor, the Construction Manager must notify the Owner that the work has been completed in accordance with the contract. Final determination of the acceptability will be made by the Owner. Upon acceptance of the project, the Owner will immediately file a notice of completion. For portions of the project not previously accepted as substantially complete, the conditions of guarantee commence on the date that the Owner files a notice of completion.

The final application for payment must be accompanied by all required documentation called for in the contract, including complete and legally effective releases or waivers of liens in a form acceptable to Owner. Subject to prior approval of Owner, Contractor may submit in lieu of the lien releases and waivers: (1) receipts of releases in full; (2) an affidavit that the releases and receipts cover all labor, services, materials, and equipment for which a lien could be filed and that all payrolls, materials, and equipment bills and other indebtedness connected with the work for which Owner or Owner's property might in any way be responsible have been paid or otherwise satisfied; and (3) consent of the surety, if any, to final payment. If any subcontractor or supplier fails to furnish a release or receipt in full, Contractor may furnish a bond or other collateral satisfactory to Owner to indemnify Owner against any lien. The final application for payment must also include all Labor Compliance documentation including all payrolls, forms, and outstanding restitution payments have been made and submitted to Owner’s satisfaction.

SUBMITTALS

1.0 GENERAL
Submittals covered by these requirements include manufacturers' information, shop drawings, test procedures, test results, samples, requests for substitutions, and miscellaneous work-related submittals. Submittals shall also include, but not be limited to, mechanical, electrical, and electronic equipment and systems, materials, reinforcing steel, fabricated items, and piping and conduit details. The Construction Superintendent shall furnish all drawings, specifications, descriptive data, certificates, samples, tests, methods, schedules, and manufacturer's installation and other instructions as specifically required in the contract documents to demonstrate fully that the materials and equipment to be furnished and the methods of work comply with the provisions and intent of the contract documents.

The Contractor and his designees will be set up as users in the City’s Virtual Project Manager (VPM). VPM is a cloud-based system that will be used to process all payments, RFI’s, submittal, reports, and will act as a file for all other project documents. If a Contractor is unable to scan documents or provide digital submittals, the City will digitize and upload the documents required as part of this Contract at the Contractor’s expense. These expenses will be billed to the Contractor on a monthly basis.

For the convenience of the Design Consultant, Owner’s Representative and Contractor, Contractor’s submittals for the Project shall be made through transmission of electronic files by email (or on USB flash drive for files exceeding 20 MB), unless hard copies are otherwise specified in the Contract Documents.

Electronic files shall be scanned in or converted to (.pdf) file format using Adobe Acrobat Version 7.0 or higher. AutoCad 2004 (or higher) drawing files shall also be in (.pdf) file format.

When specifically requested by the Design Consultant, AutoCad 2004 (or higher) files shall be made available to the Design Consultant in (.dwg) file format, transmitted on CD.

Each submittal shall be converted to a PDF document (PDF file) and submitted to Owner’s Representative for review. Drawings or other graphics converted to .PDF format shall be incorporated into the single PDF document. Pages that must be viewed in landscape format shall be rotated to the appropriate position for easy reading on screen.

Owner’s Representative, Design Consultant and Contractor will make use of certificates for electronic signatures to process all submittals and RFIs. The electronic signatures and their certificates will be developed using the Adobe Acrobat Digital Signature plug-ins. Only designated Contractor personnel will be able to sign the submittal transmittal sheet and the RFI form.

2.0 CONSTRUCTION SUPERINTENDENT'S RESPONSIBILITIES
The Construction Superintendent shall be responsible for the accuracy and completeness of the information contained in each submittal and shall assure that the material, equipment, or

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 01
16 OF 56
method of work shall be as described in the submittal. The Construction Superintendent shall verify that all features of all products conform to the specified requirements. Submittal documents shall be clearly edited to indicate only those items, models, or series of equipment, which are being submitted for review. All extraneous materials shall be crossed out or otherwise obliterated. The Construction Superintendent shall ensure that there is no conflict with other submittals and notify the Engineer in each case where his submittal may affect the work of another contractor. The Construction Superintendent shall coordinate submittals among his subcontractors and suppliers including those submittals complying with unit responsibility requirements and applicable technical sections.

The Construction Superintendent should coordinate submittals with the work so that work will not be delayed. He should coordinate and schedule different categories of submittals, so that one will not be delayed for lack of coordination with another.

The Construction Superintendent should not proceed with work related to a submittal until the submittal process is complete. This requires that submittals for review and comment shall be returned to the Construction Superintendent stamped "No Exceptions Taken" or "Make Corrections Noted." The Construction Superintendent shall certify on each submittal document that he has reviewed the submittal, verified field conditions, and complied with the contract documents.

3.0 CATEGORIES OF SUBMITTALS
A. GENERAL
Submittals fall into two general categories; submittals for review and comment, and submittals which are primarily for information only. Submittals which are for information only are generally specified as PRODUCT DATA in Part 2 of applicable specification sections.

Shop Drawings and engineering data (submittals) covering all equipment and all fabricated components and building materials which will become a permanent part of the Work under this Contract shall be submitted to Owner’s Representative for review. Submittals shall verify compliance with the Contract Documents and shall include drawings and descriptive information in sufficient detail to show the kind, size, arrangement, and the operation of component materials and devices; the external connections, anchorages, and supports required; the performance characteristics; and dimensions needed for installation and correlation with other materials and equipment. When an item consists of components from several sources, Contractor’s initial submittal shall be complete including all components.

All submittals, regardless of origin, shall be stamped with the approval of Contractor and identified with the name and number of this Contract, Contractor’s name, and references to applicable specification paragraphs and Contract Drawings. Each submittal shall indicate the intended use of the item in the Work. When catalog pages are submitted, applicable items shall be clearly identified, and inapplicable data crossed out. The current revision, issue number, and date shall be indicated on all drawings and other descriptive data.

Contractor shall be solely responsible for the completeness of each submittal.

Contractor’s stamp of approval is a representation to Owner’s Representative and Design Consultant that Contractor accepts sole responsibility for determining and verifying all quantities,

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 01
17 OF 56
dimensions, field construction criteria, materials, catalog numbers, and similar data, and that Contractor has reviewed and coordinated each submittal with the requirements of the Work and the Contract Documents.

Designation of work "by others," if shown in submittals, shall mean that the work will be the responsibility of Contractor rather than the subcontractor or supplier who prepared the submittals. Contractor shall insure that there is no conflict with other submittals and notify Owner’s Representative in each case where its submittal may affect the work of another contractor or the Owner. Contractor shall insure coordination of submittals among the related crafts and subcontractors. Contractor accepts the responsibility and expense for additional costs and delays which may result from Work performed without favorably reviewed submittals.

All deviations from the Contract Documents shall be identified as deviations on each submittal and shall be tabulated in Contractor’s letter of transmittal. Such submittals shall, as pertinent to the deviation, indicate essential details of all changes proposed by Contractor (including modifications to other facilities that may be a result of the deviation) and all required piping and wiring diagrams. The review of the shop drawing shall not constitute acceptance of deviations from the Contract Documents that are not clearly called out on the submittal.

Owner’s Representative will not accept submittals from anyone but Contractor. Submittals shall be consecutively numbered in direct sequence of submittal and without division by subcontracts or trades. Facsimile (fax) copies will not be acceptable.

B. SUBMITTALS FOR REVIEW AND COMMENT
All submittals except where specified to be submitted as product data for information only shall be submitted by the Construction Superintendent to the Engineer for review and comment.

C. SUBMITTALS (PRODUCT DATA) FOR INFORMATION ONLY
Where specified, the Construction Superintendent shall furnish submittals (product data) to the Engineer for Information only. If required, submittal requirements for operation and maintenance manuals, which are included in this category, are specified elsewhere.

4.0 TRANSMITTAL PROCEDURE
A. GENERAL
Contractor must use VPM for submittal. If Contractor is unwilling or unable to use VPM, then follow the following procedure. Submission via email will be accepted at no charge. City will charge Contractor for digitization and uploading of all paper submittals.

Unless otherwise specified, submittals regarding material and equipment shall be accompanied by Transmittal Form 01300-A specified in Section 00 62 00. Submittals for operation and maintenance manuals, information, and data shall be accompanied by Transmittal Form 01730-A specified in Section 01999. A separate form shall be used for each specific item, class of material, equipment, and items specified in separate, discrete sections, for which the submittal is required.

Submittal documents common to more than one piece of equipment shall be identified with all the

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 01
18 OF 56
appropriate equipment numbers. Submittals for various items shall be made with a single form when the items taken together constitute a manufacturer's package or are so functionally related that expediency indicates checking or review of the group or package as a whole.

A unique number, sequentially assigned, shall be noted on the transmittal form accompanying each item submitted. Original submittal numbers shall have the following format:
"XXX"; where "XXX" is the sequential number assigned by the Construction Superintendent.

Resubmittals shall have the following format: "XXX-Y"; where "XXX" is the originally assigned submittal number and "Y" is a sequential letter assigned for resubmittals, i.e., A, B, or C being the 1st, 2nd, and 3rd resubmittals, respectively. Submittal 25B, for example, is the second resubmittal of submittal 25.

B. DEVIATION FROM CONTRACT
Contractor shall utilize VPM for this process.

If the Construction Superintendent proposes to provide material, equipment, or method of work which deviates from the project manual, he shall indicate so under "deviations" on the transmittal form accompanying the submittal copies.

C. SUBMITTAL COMPLETENESS
Submittals which do not have all the information required to be submitted, including deviations, are not acceptable and will be returned without review.

5.0 REVIEW PROCEDURE
A. GENERAL
Submittals are specified for those features and characteristics of materials, equipment, and methods of operation which can be selected based on the Construction Superintendent's judgment of their conformance to the specified requirements. Other features and characteristics are specified in a manner which enables the Construction Superintendent to determine acceptable options without submittals. The review procedure is based on the Construction Superintendent's guarantee that all features and characteristics not requiring submittals conform as specified. Review shall not extend to means, methods, techniques, sequences, or procedures of construction, or to verifying quantities, dimensions, weights or gages, or fabrication processes (except where specifically indicated or required by the project manual) or to safety precautions or programs incident thereto.

Review of a separate item, as such, will not indicate approval of the assembly in which the item functions.

When the contract documents require a submittal, the Construction Superintendent shall submit using VPM. Upon Construction Manager’s or Owner’s request, the Contractor shall provide:

1. Four (4) copies of all submitted information plus one reproducible original of all information shall be transmitted with submittals for review and comment.

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 01
19 OF 56

2. Unless otherwise specified, 2 copies of all submitted information shall be transmitted with submittals (Product Data) for information only.

B. SUBMITTALS FOR REVIEW AND COMMENT:

Comments will normally be returned through VPM. If VPM is not able to be used for whatever reason, then the following procedure will apply.

Contractor’s submittals will be reviewed to determine if the equipment and materials proposed by Contractor are in general conformity with the requirements of the Contract Documents. The review is not intended to be a complete check of quantities, dimensions, fabrication details, materials, etc. indicated on the shop drawings, does not extend to Contractor’s means and methods, nor constitute a Change Order. Design Consultant’s or Owner’s Representative’s review shall not relieve Contractor of sole responsibility for errors, omissions, or deviations in the drawings and data, nor of Contractor’s sole responsibility for compliance with the Contract Documents, safety requirements and all other requirements of Applicable Law.

Unless otherwise specified, within 20 calendar days after receipt of a submittal for review and comment, the Engineer shall review the submittal and return 2 copies of the marked-up reproducible original noted in 1 above. The reproducible original will be retained by the Engineer.

The returned submittal shall indicate one of the following actions:

Color Selection: Contractor shall submit samples of colors and finishes for all accepted products before Owner’s Representative will coordinate the selection of colors and finishes with Owner. Design Consultant will prepare a schedule of finishes that include the colors and finishes selected for both manufactured products and for surfaces to be field painted or finished and will furnish this schedule to Contractor within 30 days after the date of acceptance of the last color or finish sample.

After review by the Design Consultant Owner’s Representative will return submittal review comments to Contractor via electronic files.

1. If the review indicates that the material, equipment, or work method complies with the project manual, submittal copies will be marked "NO EXCEPTIONS TAKEN." In this event, the Construction Superintendent may begin to implement the work method or incorporate the material or equipment covered by the submittal.

2. If the review indicates limited corrections are required, copies will be marked "MAKE CORRECTIONS NOTED." The Construction Superintendent may begin implementing the work method or incorporating the material and equipment covered by the submittal in accordance with the noted corrections.

Where submittal information will be incorporated in O&M data, a corrected copy shall be provided.

3. If the review reveals that the submittal is insufficient or contains incorrect data, copies will be marked "AMEND AND RESUBMIT." Except at his own risk, the

SURGE TANK PROJECT
CONTRACT 2025-1080
DIVISION 01
20 OF 56
Construction Superintendent shall not undertake work covered by this submittal until it has been revised, resubmitted, and returned marked either "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED."

4. If the review indicates that the material, equipment, or work method does not comply with the project manual, copies of the submittal will be marked "REJECTED - SEE REMARKS." Submittals with deviations which have not been identified clearly may be rejected. Except at his own risk, the Construction Superintendent shall not undertake the work covered by such submittals until a new submittal is made and returned marked either "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED."
C. SUBMITTALS (PRODUCT DATA) FOR INFORMATION ONLY:

Such information is not subject to submittal review procedures and shall be provided as part of the work under this contract and its acceptability determined under normal inspection procedures.

6.0 EFFECT OF REVIEW OF CONSTRUCTION SUPERINTENDENT'S SUBMITTALS Review of contract drawings, methods of work, or information regarding materials or equipment the Construction Superintendent proposes to provide, shall not relieve the Construction Superintendent of his responsibility for errors therein and shall not be regarded as an assumption of risks or liability by the Engineer, or by any officer or employee thereof, and the Construction Superintendent shall have no claim under the contract on account of the failure, or partial failure, of the method of work, material, or equipment so reviewed. A mark of "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED" shall mean that the Engineer has no objection to the Construction Superintendent, upon his own responsibility, using the plan or method of work proposed, or providing the materials or equipment proposed.

Contractor shall provide all pipe necessary to accommodate any vertical alignment of the pipeline and said pipe shall be represented by the net horizontal constructed length.

D. Pipeline Alignment

1. All pipelines shall be constructed with no basic variation in horizontal alignment as shown by the Drawings or as specified by the City. Pipelines may be constructed by the use of pulled joints, short joints, bevels, bends, and elbows, provided pipelines are constructed as specified.

2. In all non-critical areas and subject to the City’s approval, pipelines may be constructed at variance with vertical alignment as shown by the construction drawings by the use of pulled joints, short joints, bevels, bends, and elbows provided pipelines are constructed as specified at pipeline connections and underground interferences, and where pipeline cover is limited. The City will not approve any variation in vertical alignment until it has determined that proposed alignment is proper and modifications are in order.

E. Pipeline Tolerances

1. With regard to vertical alignment, pipelines shall be constructed so that actual flow line elevations, measured at pipe joints, are within 0.1 foot of design flow line elevations.

Pipelines, when installed, shall have continuous slope upgrade or downgrade, corresponding with design slope, without any high spots.

2. With regard to horizontal alignment, pipelines shall be constructed so that actual pipeline centerlines, measured at pipe joints, are within 0.1 foot of design pipeline

centerlines. Pipelines, when installed, shall closely follow specified horizontal alignment.

3. Pipeline construction shall conform with Construction Drawings and layout, shop, fabrication, installation, or laying drawings (design drawings which show flow line elevations and pipeline centerlines) in accordance with the above specified tolerances.

Contractor shall make or assist the City in making all necessary measurements, as determined by the City, to confirm or verify compliance with construction tolerances.

F. Pipeline Cover

1. Pipeline cover as shown by the Construction Drawings is hereby defined as design cover over pipeline. If field conditions determined during construction staking show that pipe grade changes are required to provide design cover, Contractor shall, at his expense, make required changes in pipeline grade and construct pipeline accordingly.

2. Pipeline cover from top of pipe to ground surface over pipeline shall not be less than 36 inches. Where future ground surface elevation over pipeline has been established and where actual ground surface is greater, pipeline cover shall be referenced to future (established) ground surface elevation, not actual ground surface elevation.

3.2 SURVEY MONUMENTS AND CONSTRUCTION STAKES
A. Contractor shall not disturb or destroy any existing monuments or benchmarks. If any survey monuments or benchmarks need to be removed and replaced, Contractor shall have all necessary services performed by a registered civil engineer or a licensed land surveyor. If Contractor fails to comply, the City will have said services performed at Contractor’s expense.

B. Before removing any monuments in preparation for construction, Contractor shall have a registered civil engineer or licensed land surveyor set at least four ties for each monument to be removed and replaced; after construction Contractor shall have the same registered civil engineer or licensed land surveyor replace each monument using the aforementioned ties and file a comer record for each replaced monument.

C. Unless specified otherwise, Contractor shall use construction stakes and cut sheets for pipeline construction and the City will use them for construction inspection. All construction stakes shall be set by a registered civil engineer or licensed land surveyor.

The City must approve cut sheets before actual construction. Contractor shall protect all construction stakes set for construction and he shall restore any construction stakes destroyed or disturbed. If Contractor fails to comply, the City will have services performed at Contractors expense.

3.3 UNDERGROUND UTILITIES (SUBSURFACE INSTALLATIONS)
A. Where underground utility facilities (conductors or conduits for water, gas, sewer, telephone, electric power, cable television, or other utilities) are shown on construction drawings, Contractor shall assume that service facilities (services or laterals for water gas, sewer, telephone, electric power, cable television, or other utilities) extend from each utility facility to each parcel or property whether or not service facilities are shown.

B. At least two working days but no more than fourteen calendar days before commencing any excavation on the Work, Contractor shall request Underground Service Alert (1-800- 227-2600) and non-member companies or utilities to mark or otherwise indicate the

locations of their subsurface facilities including, but not limited to, structures including vaults, main conductors or conduits, and service connections or facilities.

C. Contractor shall comply with applicable laws pertaining to subsurface installations, especially with respect to excavations and permits. Contractor shall specifically comply with applicable provisions of Sections 4215 through 4216.9 of the Government Code.

Contractor shall take all actions necessary to maintain a valid inquiry identification number during the Work.

D. At least ten days in advance, or 1,000 feet minimum ahead of pipeline trenching, Contractor shall excavate, expose, and determine (“pothole”) the exact locations, depths, and dimensions of each and every potential interference, including, but not limited to, all facilities shown specifically (depth and location) on construction drawings, or which have been marked by their respective Owner.

E. Upon learning of the existence or location of any utility facility omitted from or shown incorrectly on construction drawings, or improperly marked or otherwise indicated, Contractor shall immediately notify the City, providing full details as to depth, location, size, and function. Contractor shall immediately notify utility having jurisdiction over facility.

F. Contractor shall not interrupt or disturb any utility facility without written permission from the Utility or written order from the City. Where protection is required to ensure integrity of utility facilities located as shown on construction drawings or visible to Contractor or marked or otherwise indicated as stated herein, Contractor shall, unless otherwise provided, furnish and place all necessary protection at his expense.

G. Contractor is advised that the City has no knowledge or information about trench backfill conditions of utility facilities adjacent to or parallel with pipeline being constructed pursuant to these Specifications; therefore, Contractor shall protect against adjacent or parallel trench backfill failure. If adjacent or parallel trench fails, Contractor shall, at his expense, remove and replace said backfill material in accordance with trench backfill requirements herein and remove and replace asphalt concrete pavement and any other improvements damaged in connection therewith.

3.4 TRENCH EXCAVATION
A. Unless specified otherwise, pipelines and appurtenances shall be installed in open trench excavations to the depth and in the direction specified by the construction drawings and the City’s Standard Specifications and Drawings. Excavation for trenches shall include removal of all material of any nature as required for installation of pipe, fittings, or appurtenances and shall include blasting, either sloping or shoring, and all necessary dewatering, if any, all at Contractor’s expense. Contractor is advised that unsuitable earth may be encountered during trenching operations. Where such material is encountered, Contractor shall, at his expense, remove such material, discard it at legal disposal site(s), and thereafter replace it with approved backfill material.

B. Excavation Safety Drawings: Before excavating any earth or soil to a depth of five (5) feet or more, Contractor shall, pursuant to Labor Code Section 6705, submit to the City detailed drawings (hereafter referred to as excavation safety drawings) showing design of shoring, bracing, sloping, or other provisions to be made for worker, individual, or property protection.

Contractor at his expense, who shall affix his signature and seal to each sheet of said excavation safety drawings. Contractor shall not excavate until the City has received and acknowledged properly certified excavation safety drawings. Contractor shall comply with all other applicable requirements of Labor Code Section 6705 and, as therein provided, no requirements of that Section shall be construed to impose tort liability on City or City’s representatives, including City’s Engineer.

C. Trench and Bell Hole Sloping or Shoring: Trenches and bell holes shall be adequately sloped or shored so that earth will not slide or settle into trench, so that all existing improvements and utilities (above and below ground) will be fully protected from damage, and so that workers and individuals are protected from injury. At minimum, Contractor shall keep toe of trench spoil at least 5 feet from top of trench. Contractor shall assume full responsibility for all damages caused by inadequate sloping or shoring. Contractor shall make all necessary repairs or perform all reconstruction at his expense, and he shall bear all other expenses resulting from such damages.

D. Unless specified otherwise, all pipeline trenches within pipe zone shall, wherever possible, have vertical sides and minimum widths as specified on the standard drawings, however, trenches shall be sloped or shored as required for worker, individual, and property protection.

E. Whenever maximum allowable trench width, as shown by the Drawings, is exceeded for any reason, the City may, at its discretion, require Contractor, at his expense, to cradle pipe (Class B Portland cement concrete) or to provide higher class bedding to support pipe as required to limit load on pipe to allowable supporting strength. The City shall approve method of support prior to its use.

F. Trenches shall be excavated to depths specified by or shown on construction drawings or as otherwise directed by the City. If trench excavation is carried below grade without direction or permission, Contractor shall, at his expense, refill trench to proper grade with moist clean sand, sand and gravel, or other suitable material as approved by the City, tamped in place to 90% relative compaction minimum. Excess excavated material shall be incorporated in backfill or discarded at legal disposal site(s) by Contractor at his expense.

3.5 WELDED STEEL PIPE INSTALLATION
A. Pipe Installation

1. Pipe manufacturer, fitting manufacturer, and material supplier, in addition to the City and the City’s representative, shall have access to the Work during installation.

Contractor shall use assistance provided by either manufacturer or supplier where required for proper installation of pipe, fittings, or materials; however, Contractor shall limit role of either manufacturer or supplier to advisory service.

2. Contractor shall not move pipe using dozer blades, backhoe buckets, or the like (sharp metal surfaces). Contractor shall use nylon chokers or straps, not steel slings, in moving, placing, or setting pipe. Nylon chokers or straps shall be placed at third points (one-third length of pipe from each end).

3. All out-of-round pipe shall be rejected and removed from the Work site immediately.

Rejected pipe shall be replaced immediately. Contractor shall not use hammers, bars, wrenches, or other tools to modify pipe ends to accommodate installation.

5. All pipe and fittings shall be laid true to line and grade and at the locations shown by the construction drawings or as specified. Pipe and fittings shall be installed in accordance with applicable sections of AWWA M11, “Steel Pipe Manual”. Bell ends shall be placed uphill unless otherwise permitted.

6. All flanges shall be fully welded to pipe on both faces, one pass minimum on the inside and two passes minimum on the outside. Pipe linings shall extend to mating faces of flanges and pipe coatings shall extend to backs of flanges, tapered as necessary for installation of bolts and nuts. All exposed steel shall be field coated with an approved bitumastic material.

7. Special care shall be taken to avoid damaging lining or coating during lowering of pipe into trench and making of field joints. Unless specified otherwise, field joints shall be bell and spigot rubber gasket joints, continuity bonded (two evenly spaced bonding clips per joint minimum). Flanged joints, welded joints, and mechanical joints may be required for particular applications.

8. After pipe has been set in trench, exterior of spigot and interior of bell shall be thoroughly cleaned. Lubricant as recommended by pipe manufacturer and as approved by the City shall be applied to rubber gasket and said gasket shall then be snapped into place and excess lubricant removed. Lubricant shall be water soluble, nontoxic, shall impart no objectionable taste or odor to water, shall have no deteriorating effects on the rubber gaskets, and shall not support the growth of bacteria.

9. Before inserting spigots into bells, to make joints, bells shall be hand mortared with quick setting non-shrink commercial grout mixed with an approved bonding agent.

Once spigots have been inserted into bells, joints shall be gauged to ensure that gaskets have been properly seated.

10. For pipe 24 inches and larger, Contractor shall relieve (equalize) gaskets before laying to prevent gaskets from being tight on one side of pipe and slack on the other side, and adversely affecting seal. Contractor shall lift gaskets with a round blunt tool (like the shaft of a screwdriver) and roll it around the circumference of the spigot end at least once and preferably twice.

11. For pipe less than 24 inches in diameter, sufficient quantities of moist cement mortar shall be placed on interior joining ends of pipe to completely fill space between respective mortar linings. Moist mortar shall be placed only after respective mortar linings have been properly wetted. Moist mortar shall not be placed against dry mortar linings. Excess mortar shall be removed by drawing an approved pipe cleaning tool through the pipe after joints have been made (pipe sections have been joined). For fully welded joints, pipe sections shall be pulled together and restrained with come along devices, or hoists with chains and slings, and mortar shall be allowed to set for twenty minutes before welding joint. Once joint has been pulled closed and cleaning tool has been drawn through pipe sections, pipe alignment shall not be adjusted, nor shall pipe be bounced or hammered. Come along devices, or hoists with chains and slings, shall be removed only after joint has been fully welded.

12. For pipe 24 inches in diameter and larger, cement mortar shall be placed on interior joining ends from inside pipe after it has been set. Moist mortar shall be applied only after mortar linings have been properly wetted. Moist mortar shall not be placed against dry mortar linings. Excess mortar and debris shall be removed by hand or by other means acceptable to and approved by the City.

13. For cement mortar coated pipe, joint exteriors shall be coated with cement mortar utilizing a joint diaper. Said diaper shall be furnished by pipe manufacturer and shall be

CONTRACT 2025-1080
33 11 13 – PIPELINES AND APPURTENANCES
15 of 18
centered over joint and securely fastened to pipe. Cement mortar joint mix consisting of one part Portland cement to two parts (by weight) clean, sharp sand, shall contain just enough water to allow mix to be poured into diaper and flow around circumference of joint. Said mix shall be allowed to set prior to backfilling around joint.

14. Joints shall be completed to provide continuous interior lining and exterior coating.

Field lining and coating must equal or exceed shop lining and coating when completed with respect to strength, uniformity, and density and there shall be no voids between lining or coating and steel cylinder.

15. If cement mortar lining has to be removed, Contractor shall scribe, chisel, and remove the lining using appropriate tools. If cement mortar coating has to be removed, Contractor shall first scribe, then saw cut said coating 3/4 of its thickness, and then remove coating using a chisel driven by a hammer, chipping gun, or other suitable tool.

Impact shall be applied parallel with pipe barrel, not perpendicular thereto.

16. At the end of each day’s work, all openings in the pipeline shall be plugged with watertight, expandable plugs or approved equal. Said plugs shall be secured in place so that they cannot be removed by children or animals.

B. Field Welding

1. Whenever field welding is required, Contractor shall attach welding machine ground to pipe only with clamps or other means acceptable to the City unless an alternative means is specified.

2. Unless specified otherwise, field welded or thrust restrained joints shall consist of flanged joints or fully welded joints. All flanges shall be fully welded to pipe on both faces, one pass minimum on the inside and two passes minimum on the outside.

Welded joints shall be made with pipe having ends belled for welding, or alternatively, ends belled for rubber gasket joints, provided pipe manufacturer furnished filler rods of proper diameter, length, and curvature are installed in accordance with pipe manufacturer’s recommendations, as approved by City. Belled ends shall not be deformed to accomplish fully welded joints. Full welds for all joints shall be accomplished with two welding passes (beads) minimum.

C. Field Cement Mortar Lining and Cement Mortar Coating: Whenever field cement mortar lining and cement mortar coating is permitted by the City for either repair or fabrication, Contractor shall comply with the following procedures:

1. Cement Mortar Lining
a. Contractor shall square the edge of the remaining lining, leaving no feather edge, and shall clean metal surfaces with a stiff wire brush. b. Contractor shall apply approved bonding agent to both steel area and edges of adjacent lining. Cement mortar shall then be applied to the area being patched and worked and finished with a trowel until smooth. Contractor shall brush on approved curing compound over the surface of the patch to prevent rapid evaporation of moisture. Otherwise, Contractor shall keep the patched mortar moist by covering it with wet burlap. The pipe shall not be moved until the cement mortar achieves its initial set, not less than three hours.
c. Cement mortar shall consist of not less than one part cement to three parts sand, thoroughly mixed before any water addition. Cement mortar may be approved commercial, packaged dry mortar mix. Cement mortar shall be mixed separately for each area to be patched. Quantity of water shall be just sufficient so that when mortar is firmly compressed into a ball, it will hold its shape without slump.
