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 his or her 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 his or her 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

Requests to clarify the source of materials, equipment, suppliers, or any other matter that does not modify, change, increase, 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.

2. BID PRICES: Bid prices must include everything necessary for the completion of the work including, but not limited to, providing the materials, equipment, tools, plant and other facilities, and the management, superintendence, labor and services, and bonds. Bid prices must include allowance for federal, state, and local taxes. In the event of a difference between a price quoted in words and a price quoted in figures for the same quotation, the words are the amount bid. In the event that the product of a unit price and an estimated quantity does not equal the extended amount quoted, the unit price governs, and the correct product of the unit price and the estimated quantity is deemed to be the amount bid. If the sum of two or more items in a bidding schedule does not equal the total amounts quoted, the individual item amounts govern, and the correct total is deemed to be the amount bid.

3. BIDDER'S SIGNATURE AND AUTHORITY: If the bid is made by an individual, his or her name, signature, and post office address must be shown; if made by a

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31

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.

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.

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.

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

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
64 OF 91
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.

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.

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00

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 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 full-size 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.

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 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.

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
67 OF 91
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 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.

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
68 OF 91
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 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.

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 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.

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
70 OF 91
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 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

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
71 OF 91
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 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.

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:

1. Coverage shall be at least as broad as:

Commercial General Liability (CGL): Insurance Services Office (ISO) Form CG 00 01 covering CGL on an “occurrence” basis, including products and completed operations, property damage, bodily injury and personal & advertising injury with limits no less than $5,000,000 per occurrence. If a general aggregate limit applies, either the general aggregate limit shall apply separately to this project/location (ISO CG 25 03 or 25 04) or the general aggregate limit shall be twice the required occurrence limit. The required insurance must be maintained until final acceptance of the work and must continue for a period of 365 calendar days after the final acceptance of the work.
b. Automobile Liability: Insurance Services Office Form CA 0001 covering Code 1 (any auto), with limits no less than $5,000,000 per accident for bodily injury and property damage.

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”. 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:

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
75 OF 91

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 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

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
76 OF 91
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.

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

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
77 OF 91
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, or assigned Calendar day milestones and completion dates; and the Contractor agrees to pay the liquidated 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.

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00

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, including completing the work within the time prescribed.

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.

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
79 OF 91

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 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

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
80 OF 91
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.

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.

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
81 OF 91
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 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,

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
82 OF 91
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.

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

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
83 OF 91
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.
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.

4. 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.

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.

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
84 OF 91
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.

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

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
85 OF 91
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.

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

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
86 OF 91
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 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.

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
87 OF 91

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 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.

When equipment is used on the extra work for less than five days, hourly rates will be used. Less than 30 minutes of operation is considered one-half hour of operations.

When equipment is used on the extra work for more than five days, daily rates apply. In that case, less than four hours of operation is considered to be one-half day of operation.

6. PROFESSIONAL SERVICES: Professional services are included in "actual necessary expense" provided that the Owner has determined that such services are necessary and that the Construction Manager has authorized in writing the provision of such services.

7. OTHER COSTS: Charges for items not included in paragraphs 7.02 F.1 through 6 may be included as "actual necessary expense" if such additional items are authorized in advance and in writing by the Construction Manager.

7.03 CHARGES TO CONTRACTOR
Everything charged to the Contractor under the terms of this contract must be paid by the Contractor to the Owner on demand. Such charges may be deducted by the Owner from money due or to become due to the Contractor under the contract. The Owner may recover such charges from the Contractor or from its surety.

7.04 COMPENSATION TO OWNER FOR TIME EXTENSION
The Owner, in exchange for granting an extension of time for avoidable delay, must be compensated by the Contractor for the actual costs to the Owner of engineering, inspection, general supervision, and overhead expenses that are directly chargeable to the work and accrue during the period of such extension. The actual costs do not include charges for final inspection and preparation of the final estimate by the Owner.

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. The Contractor will acknowledge receipt of the acceptance notice in writing, indicating acceptance of all of its terms and provisions.

Upon receipt of the Contractor's acknowledgment letter, the Owner will take possession of the work or portion of the work and put it into its intended service. The date that the work or

BEACHFRONT PARK TOLOWA CULTURAL TRAIL
CONTRACT 2025-1002.31
DIVISION 00
89 OF 91
portion of the work is put into service will become the date of substantial completion. Unless otherwise specified, warranties will begin on the date of substantial completion.

Subsequent to the substantial completion date, the Owner may exclude the Contractor from the work during such periods when construction activities might interfere with the operation of the project. The Owner, however, will allow the Contractor reasonable access for completion or correction of incomplete punch list items.

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.

If, after reviewing the Contractor's final application for payment, including all documentation required, the Construction Manager determines that the work is complete, then the Construction Manager will recommend that final payment, including all retainages, be made by the Owner. The final payment will be due and payable by the Owner within 30 days after any legal notice periods have expired.

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.

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.

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.

3.7 STRUCTURAL BACKFILL
Do not place backfill until structure footings or other portions of structure of facility have been inspected by the City’s representative and approved for backfilling. Do not deposit backfill material against back of concrete retaining walls, foundations or reinforced concrete structures until concrete has developed strength of not less than 75% of full strength using specified test procedures. Place backfill in horizontal layers, moistened and thoroughly tamped, rolled or otherwise compacted. Water settling will not be permitted. Place backfill such that no additional unbalanced loading may occur during placement.

3.8 TRENCH BACKFILL
A. The pipe bedding is defined as the portion of the trench between the trench subgrade and the bottom of the pipe. After compacting the bedding, the Contractor shall perform a final trim using a string line for establishing grade, such that each pipe section when first laid shall be continually in contact with the bedding along the extreme bottom of the pipe.

Excavation for pipe bells and welding shall be made as required.

B. After pipe has been properly laid, exterior joints grouted and inspected, backfilling shall be commenced. Compaction method or methods used shall result in obtaining the compaction of the backfill in the various specified zones and within the maximum lifts specified. Compaction methods used shall not damage pipe, adjacent ground, existing improvements, or improvements installed as part of Work.

C. If a moveable trench shield is used during excavation, pipe installation, and backfill operations, the shield shall be moved by lifting the shield free of the trench bottom or backfill and then moving the shield horizontally. The Contractor shall not drag trench shields along the trench causing damage or displacement to the trench sidewalls, the pipe or the bedding and backfill.

D. Water settling may be used in pipe zone and trench zone in lieu of mechanical compaction, only where material being backfilled is sufficiently sandy and permeable so that specified compaction is achieved. Compaction by saturation shall be accomplished by inserting a pipe, through which water is being supplied under pressure, to the bottom of the lift of material to be consolidated and applying to each square yard or lesser surface area in this manner sufficient water to completely saturate the backfill, there over and cause obvious settlement.

1. Vibrating compacting equipment may be necessary to supplement water saturation process where required densities cannot be attained by saturation alone.

2. If water does not readily drain from trench, it shall be removed by sump pump.

E. Trench Backfill by Zones: Backfill shall be constructed by zones, regardless of compaction method used. The compaction requirements for each zone shall be as follows, unless otherwise specified.

1. Pipe Zone Backfill: Backfill from below pipe to less than 12 inches above top of pipe.

The pipe shall be backfilled with the specified material per Section 2.1 F. to 90% compaction. The Contractor shall exercise care to prevent damage to the pipeline coating, cathodic bonds, and the pipe itself during the installation and backfill

operations. Backfill shall be placed in layers simultaneously on each side of the pipe for full trench width. In placing and compacting backfill give particular attention to underside of pipe and fittings to provide firm support along full pipe length.

2. Trench Zone Backfill: Backfill in pipe trench above pipe zone and below Surface Zone.

The zone shall be backfilled with the specified material per Section 2.1 F to 90% compaction. Backfill may be either mechanical compaction or water settling, based on characteristics of material.

3. Surface Zone Backfill: Upper 12 inches of trench to finish surface. Zone shall be backfilled with the specified material per Section 2.1 F. If finish surface is in unimproved or landscape area, 80% compaction is sufficient. If finish surface is within travel way compaction shall be 90%. If finish surface is to be paved, compaction shall be 95%.

3.9 FIELD TESTING
Compaction testing method for pipelines shall be per the Standard Specifications. Compaction testing method for structural foundation shall be per the five (5) layer test ASTM Standard D557 of the latest edition. Compaction test will be performed by the Water Company as required.

The Contractor shall pay all costs for any retesting of work not conforming to the Specifications and the Contract Drawings.
