Subject: Approval of Plans and Specifications and Authorization to Advertise for Bids for the Sewer Pipeline Rehabilitation 2022 Project

Districts: 1, 2 and 3

Recommended Action
Adopt a resolution approving the plans and specifications and authorizing the City Clerk to advertise for bids for the Sewer Pipeline Rehabilitation 2022 Project, Capital Improvement Program No. 5503-21.

Executive Summary
The repair and rehabilitation of sewer mains that have a high risk of failure is an integral component of a well-managed sewer collection system. The city’s Sewer System Rehabilitation and Replacement Program ensures that wastewater is conveyed efficiently and effectively to the treatment plant, helps maintain high levels of service to customers, reduces sewer spills and protects the public health and the environment.

Every few years, this program repairs or replaces sewer mains throughout the system that are identified through condition assessments as having a high risk of failure. This project uses trenchless pipe rehabilitation technologies in approximately 5,300 lineal feet of sewer mains at various locations that have a high of risk defects, as shown on the map on Exhibit 2 and the list on Exhibit 3.

City Council approval of these plans and specifications is required under Carlsbad Municipal Code Section 3.28.080(E) because the expected value for this work is greater than $200,000.

Staff recommend that the City Council approve the plans and specifications and authorize the City Clerk to advertise and receive project bids.

Discussion
The Utilities Department is focused on managing assets in a way that maintains the integrity of the sewer collection system and keeps wastewater in the system as it is conveyed to the April 19, 2022

treatment plant. The Wastewater Division of the Utilities Department has developed a comprehensive condition assessment program using closed circuit TV inspections to identify defects in sewer mains. A multiyear program, Sewer System Rehabilitation and Replacement, has been developed to rehabilitate or repair sewer mains that are determined during routine condition assessments to have significant defects and a high risk of failure. Funding was identified in the 2019 Asset Management Master Plan, which was approved by the City Council in September 2019.

The Utilities Department prioritizes the rehabilitation of sewer mains throughout the collections system using business risk scores that are numerical values assigned to each sewer main segment. The business risk score is determined by combining two scores:
• Likelihood of failure is calculated based on the number and severity of pipeline defects found during CCTV condition assessments that are performed, reviewed and coded by certified operators within the Utilities Department
• Consequence of failure is pre-determined for each sewer main based on parameters such as location, volume of wastewater and potential impact of a failure on the environment and the public, and does not change based on inspections
Higher risk scores indicate that the sewer main has a higher likelihood of failure and/or a higher consequence of failure so the risk that the city is assuming is higher, and the pipes with higher scores are prioritized first for rehabilitation or replacement.

Sewer mains are exposed to gases and other elements that can corrode the pipe or create breaks or cracks. The purpose of the program is to use data to identify and prioritize sewer main rehabilitation and replacement to minimize the risk exposure to the city, as well as to protect public health and the environment.

The program’s programmatic nature allows the Utilities Department to put together larger rehabilitation projects every few years and take advantage of potentially lower construction costs associated with higher volumes of work. Sewer mains with severe structural defects that are in imminent danger of failure are fixed as quickly as possible using smaller contracts, but the overall intent of the program is to minimize severe risk by regularly rehabilitating and replacing sewer mains before they fail completely.

The project will rehabilitate approximately 5,300 lineal feet of clay sewer mains in the city’s sewer service area by lining the mains with either cured-in-place pipe technology or a spiral wound liner. No excavations will be necessary as these are trenchless pipe rehabilitation technologies and the liners are inserted into the existing mains using manholes for access.

Trenchless methods reduce construction cost, construction duration and impacts to the community when compared to conventional dig and replace methods of repair.

The project’s construction contract will contain general performance standards, technical specifications, sequencing and notification requirements to minimize disruptions, and include a five-year warranty period. Retention will be withheld from each progress payment until final acceptance. The construction is expected to last approximately one year, and the contract April 19, 2022

states that the city may assess liquidated damages1 for each day in excess of the time specified for completion of the work.

Options
Staff provide the following options for the City Council’s consideration:

1. Adopt a resolution approving the plans and specifications and authorizing the City Clerk to advertise for bids for the project
Pros
• Addresses known deficiencies in the sewer collection system • There is adequate funding in Capital Improvement Program Project No. 5503-21 • Minimizes the risk of further sewer condition deterioration and increased costs due to inflation
Cons
• None identified

2. Do not adopt a resolution approving the plans and specifications and authorizing the City Clerk to advertise for bids for the project
Pros
• None identified
Cons
• The sewer main deficiencies identified in the scope of work would continue to deteriorate, with a potential for pipe failures, sewer spills, loss of service and harm to the environment
• Work deferred to a future date could result in an overall project cost increase due to document rework and future construction cost increases due to inflation • Work deferred to a future date would also delay work that has been identified for future years, causing an overall decrease in the condition of the sewer collection system
Staff recommend Option 1: Adopt a resolution approving the plans and specifications and authorizing the City Clerk to advertise for bids for the project.

Fiscal Analysis
No additional funding is being requested. The engineer’s estimate of the construction cost of the project is $641,200. The total project cost of $987,400 includes the construction contract, a contingency for change orders, construction management and inspection; and engineering and administrative support for contractor shop drawings, requests for information, meetings and community outreach.

1 Liquidated damages are an estimate of otherwise intangible or hard-to-define losses to one of the parties in as contract. Having them in a contract allows for the payment of a specified sum should one of the parties be in breach of the contract.

Bidders are further urged to review sections 2 -3 SUBCONTRACTS of the General Provisions.

CAUTIONS This form will be used by the Agency to determine the percentage of work that the Bidder proposes to perf orm. Bidders are cautioned that failure to provide complete and correct information may result in rejection of the bid as non -responsive. Any bid that proposes perfor- mance of more than 50 percent of the work by subcontractors or otherwise to be p erformed by forces other than the Bidder’s own organizat ion will be rejected as non -responsive. Specialty items of work that may be so designated by the Engineer on the “Contractor’s Proposal” are not included in computing the percentage of work proposed to be performed by the Bidder.

INSTRUCTIONS The Bidder shall set forth the name and location of business of each and every subcontractor whom the Bidder proposes to perform work or labor or render service in or about the work or improvement, and every subcontractor licensed as a contractor by the State of Cali- fornia whom the Bidder proposes to specially fabricate and install any portion of the work or im- provement according to detailed drawings contained in the plans and specifications in excess of one-half of one percent (0.5%) of the Bidder’s total bid or, in the case of bids or offers for the construction of streets and highways, including bridges, in excess of one -half of one percent (0.5%) or ten thousand dollars ($10,000) whichever is greater. Said name(s) and lo cation(s) of business of subcontractor(s) shall be set forth and included as an integral part of the bid offer.

The Designation of Subcontractors form must be submitted as a part of the Bidder’s sealed bid.

Failure to provide complete and correct informat ion may result in rejection of th e bid as non - responsive.

Suppliers of materials from sources outside the limits of work are not subcontractors. The value of materials and transport of materials from sources outside the limits of work, as shown on the plans, shall be assigned to the Cont ractor or the Subcontractor as the case may be, that the Bidder proposes as installer of said materials. The value of material incorporated in any Subcon- tractor-installed bid item that is supplied by the Bidder shall be included as a part of the work that the Bidder proposes to be performed by the Subcontractor installing said item.

When a Subcontractor has a Carlsbad business license, the number must be entered on the proper form. If the Subcontractor does not have a valid business license, enter “NONE” in the appropriate space.

When the Bidder proposes using a Subcontractor to construct or install less than 100 percent of a bid item, the Bidder shall attach an explanation sheet to the Designation of Subcontractor form.

The explanation sheet shall clearly apprise the City of the specific facts that show the Bidder proposes to perform no less than fifty percent (50%) of the work with its own forces.

Determination of the subcontract amounts for purposes of award of the contr act shall be deter- mined by the City Council in conformance with the provisions of the contract documents and the various supplemental provisions. The decision of the City Council shall be final.

Revised 6/12/18 Contract No. 5503-21 Page 23 of 122

Any assignment of money shall be subject to all proper withholdings in favor of the Agency and to all deductions provided for in the Contract. All money withheld, whether as- signed or not, shall be subject to being used by the Agency for completion of the Work, should the Contractor be in default.

2-3 SUBCONTRACTS.

2-3.1 General. Each Bidder shall comply with the Chapter of the Public Contract Code including Sections 4100 through 4113. The following excerpts or summaries of some of the requirements of this Chapter are included below for information:

The Bidder shall set forth in the Bid, as provided in 4104:

“(a) The name and location of the place of business of each subcontractor who will perform work or labor or render service to the prime contractor in or about the construction of the work or improvements, or a subcontractor licensed by the State of California who, under subcontract to the p rime contractor, specially fabricates and installs a portion of the work or improvement according to detailed drawings contained in the plans and specifications, in an amount in excess of one-half of 1 percent of the prime contractor’s total bid, or, in the case of bids or offers for the construction of streets or highways, including bridges, in excess of one -half of 1 percent of the prime contractor’s total bid or ten thousand dollars ($10,000), which- ever is greater.”

“(b) The portion of the work which will be done by each such subcontractor under this act. The prime contractor shall list only one subcontractor for each such portion as is defined by the prime contractor in his bid.”

If the Contractor fails to specify a Subcontractor, or specifies more than one Subcontractor for the same portion of the work to be performed under the Contract (in excess of one-half of 1 percent of the Contractor’s total Bid), the Contractor shall be qualif ied to perform that portion itself, and shall perform that portion itself, except as otherwise provided in the Code.

As provided in Section 4107, no Contractor whose Bid is accepted shall substitute any person as Subcontractor in place of the Subcontracto r listed in the original Bid, except for causes and by procedures established in Section 4107.5. This section provides procedures to correct a clerical error in the listing of a Subcontractor.

Section 4110 provides that a Contractor violating any of the provisions of the Chapter violates the Contract and the Board may exercise the option either to cancel the Contract or assess the Con- tractor a penalty in an amount of not more than 10 percent of the subcontract involved, after a public hearing.

Revised 6/15/17 Contract No. 5503-21 Page 55 of 122

Should the Contractor fail to adhere to the provisions requiring the Contractor t o complete 50 percent of the contract price with its own organization, the Agency may at its sole discretion elect to cancel the contract or deduct an amount equal to 10 percent of the value of the work performed in excess of 50 percent of the contract price by other than the Contractor’s own organization. The Board shall be the sole body for determination of a violation of these provisions. In any proceed- ings under this section, the prime contractor shall be entitled to a public hearing before the Board and shall be notified ten (10) days in advance of the time and location of said hearing. The deter- mination of the City Council shall be final.

2-3.2 Additional Responsibility. The Contractor shall give personal attention to the fulfillment of the Contract and shall keep the Work under its control.

The Contractor shall perform, with its own organization, Contract work amounting to at least 50 percent of the Contract Price except that any designated “Specialty Items” may be performed by subcontract, and the amount of any such “Specialty Items” so performed may be deducted from the Contract Price before computing the amount required to be performed by the Contractor with its own organization. “Specialty Items” will be identified by the Agency in the Bid or Proposal.

Where an entire item is subcontracted, the value of work subcontracted will be based on the Contract Unit Price. When a portion of an item is subcontracted, the value of work subcontracted will be based on the estimated percentage of the Contract Unit Price. This will be determined from information submitted by the Contractor, and subject to approval by the Engineer.

Before the work of any Subcontractor is started, the Contractor shall submit to the Engineer for approval a written statement showing the work to be subcontracted giving the name and business of each Subcontractor and description and value of each portion of the work to be so subcon- tracted.

2-3.3 Status of Subcontractors. Subcontractors shall be considered employees of the Con- tractor, and the Contractor shall be responsible for their work.

2-4 CONTRACT BONDS. Before execution of the Contract, the Bidder shall file surety bonds with the Agency to be approved by the Board in the amounts and for the purposes noted below.

Bonds issued by a surety, who is authorized to issue bonds in California, and whose bonding limitation shown in said circular is sufficient to provide bonds in the amount required by the Con- tract shall be deemed to be approved unless specifically rejected by the Agency. Bonds from all other sureties shall be accompanied by all of the documents enumerated in Code of Civil Proce- dure 995.660 (a). The Bidder shall pay all bond premiums, costs, and incidentals.

Each bond shall incorporate, by reference, the Contract and be signed by both the Bidder and Surety and the signature of the authorized agent of the Surety shall be notarized.

The Contractor shall provide a faithful performance/warranty bond and payment bond (labor and materials bond) for this contract. The faithful performance/warranty bond shall be in a sum not less than one hundred percent of the tot al amount payable by the terms of this contract. The Contractor shall provide bonds to secure payment of laborers and materials suppliers in a sum not less than one hundred percent of the total amount payable by the terms of this contract.

Both bonds shall extend in full force and effect and be retained by the Agency during this project until they are released according to the provisions of this section.

Revised 6/15/17 Contract No. 5503-21 Page 56 of 122

The faithful performance/warranty bond will be reduced to 25 percent of the original amount 30 days after recordation of the Notice of Completion and will remain in full force and effect for the one year warranty period and until all warranty repairs are completed to the satisfaction of the Engineer. The bonds to secure payment of laborers and materials suppliers shall be released six months plus 30 days after recordation of the Notice of Completion if all claims have been paid.

All bonds are to be placed with a surety insurance carrier admitted and authorized to transact the business of insurance in California and whose assets exceed their liabilities in an amount equal to or in excess of the amount of the bond. The bonds are to contain the following documents:

1. An original, or a certified copy, of the un-revoked appointment, power of attorney, by laws, or other instrument entitling or authorizing the person who executed the bond to do so.

2. A certified copy of the certificate of authority of the insurer issued by the insurance com- missioner.

If the bid is accepted, the Agency may require a financial statement of the assets and liabilities of the insurer at the end of the quarter calendar year prior to 30 days next preceding the date of the execution of the bond. The financial statement shall be made by an officer's certificate as defined in Section 173 of the Corporations Code. In the case of a foreign insurer, the financial statement may be verified by the oath of the principal officer or manager residing within the United States.

Should any bond become insufficient, the Contractor shall renew the bond withi n 10 days after receiving notice from the Agency.

Should any Surety at any time be unsatisfactory to the Board, notice will be given the Contractor to that effect. No further payments shall be deemed due or will be made under the contract until a new Surety shall qualify and be accepted by the Board.

Changes in the Work or extensions of time, made pursuant to the Contract, shall in no way release the Contractor or Surety from its obligations. Notice of such changes or extensions shall be waived by the Surety.

SECTION 3 – CHANGES IN WORK

3-1 CHANGES REQUESTED BY THE CONTRACTOR.

3-1.1 General. Changes in the Plans and Specifications, requested in writing by the Contractor, which do not materially affect the Work and which are not detrimental to the Work or to the inter- ests of the Agency, may be granted by the Engineer. Nothing herein shall be construed as grant- ing a right to the Contractor to demand acceptance of such changes.

3-1.2 Payment for Changes Requested by the Contractor. If such changes are granted, they shall be made at a reduction in cost or no additional cost to the Agency.

3-2 CHANGES INITIATED BY THE AGENCY.

3-2.1 General. The Agency may change the Plans, Specifications, character of the work, or quantity of work provided the total arithmetic dollar value of all such changes, both additive and deductive, does not exceed 25 percent of the Contract Price. Should it become necessary to exceed this limitation, the change shall be by written Supplemental Agreement between the Con- tractor and Agency, unless both parties agree to proceed with the change by Change Order.

Change Orders shall be in writing and state the dollar value of the change or established method of payment, any adjustment in contract ti me of completion, and when negotiated prices are in- volved, shall provide for the Contractor’s signature indicating acceptance.

3-2.2 Payment.

3-2.2.1 Contract Unit Prices. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does not involve substantial change in character of the work from that shown on the Plans or specified in the Specifications, then an adjustment in payment will be made. This adjustment will be based upon the increase or decrease in quantity and the Contract Unit Price.

If the actual quantity of an item of work covered by a Contract Unit Price and constructed in con- formance with the Plans and Specifications varies from the Bid quantity by 5 0 percent or less, payment will be made at the Contract Unit Price. If the actual quantity of said item of work varies from the Bid quantity by more than 50 percent, payment will be made per Section 3-2.2.2 or 3-

2.2.3 as appropriate.

If a change is ordered in an item of work covered by a Contract Unit Price, and such change does involve a substantial change in the character of the work from that shown on the Plans or specified in the Specifications, an adjustment in payment will be made per Section 3-2.4.

3-2.2.2 Increases of More Than 50 Percent. Should the actual quantity of an item of work cov- ered by a Contract Unit Price and constructed in conformance with the Plans and Specifications, exceed the Bid quantity by more than 50 percent, payment for the quantity in excess of 150 per- cent of the Bid quantity will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3. The Extra Work per Section 3-3, basis of payment, shall not include fixed costs. Fixed costs shall be deemed to have been recovered by the Contractor through payment for 150 percent of the Bid quantity at the Contract Unit Price.

Revised 6/15/17 Contract No. 5503-21 Page 68 of 122

3-2.2.3 Decreases of More Than 5 0 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price, and constructed in conformance with the Plans and Specifica- tions, be less than 5 0 percent of the Bid quantity, an adjustment in payment will not be made unless so requested in writing by the Contractor. If the Contrac tor so requests, payment will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Enginee r, on the basis of Extra Work per Section 3-3; however, in no case will payment be less than would be made for the actual quantity at the Con- tract Unit Price nor more than would be made for 50 percent of the Bid quantity at the Contract Unit Price.

3-2.3 Stipulated Unit Prices. Stipulated Unit Prices are unit prices established by the Agency in the Contract Documents as distinguished from Contract Unit Prices submitted by the Contrac- tor. Stipulated Unit Prices may be used for the adjustment of Contract changes when so specified in the Special Provisions.

3-2.4 Agreed Prices. Agreed Prices are prices for new or unforeseen work, or adjustments in Contract Unit Prices per Section 3-2.2, established by mutual agreement between the Contractor and the Agency. If mutual agreement cannot be reached, the Engineer may direct the Contractor to proceed on the basis of Extra Work in accordance per with Section 3-3, except as otherwise specified in Sections 3-2.2.2 and 3-2.2.3.

3.2.4.1 Schedule of Values. Prior to construction, within 14 calendar days, Contractor shall pro- vide a schedule of values for all lump sum bid items that shall be used for the purpose of progress payments. The prices shall be valid for the purpose of change orders to the project.

3.2.5 Eliminated Items. Should any Bid item be eliminated in its entirety, payment will be made to the Contractor for its actual costs incurred in connection with the eliminated item prior to notifi- cation in writing from the Engineer so stating its elimination. If material conforming to the Plans and Specifications is ordered by the Contractor for use in the eliminated item prior to the date of notification of elimination by the Engineer, and if the order for that material cannot be canceled, payment will be made to the Contractor for the actual cost of the material. In this case, the material shall become the property of the Agency. Payment will be made to the Contractor for its actual costs for any further handling. If the material is returnable, the material shall be returned and payment will be made to the Contractor for the actual cost of cha rges made by the supplier for returning the material and for handling by the Contractor. Actual costs, as used herein, shall be computed on the basis of Extra Work per Section 3-3.

3-3 EXTRA WORK.

3-3.1 General. New or unforeseen work will be classified as “extra work” when the Engineer determines that it is not covered by Contract Unit Prices or stipulated unit prices.

3-3.2 Payment.

3-3.2.1 General. When the price for the extra work cannot be agreed upon, the Agency will pay for the extra work based on the accumulation of costs as provided herein.

Revised 6/15/17 Contract No. 5503-21 Page 69 of 122
3-3.2.2 Basis for Establishing Costs.

(a) Labor. The costs of labor will be the actual cost for wages of workers performing the extra work at the time the extra work is done, plus employer payments of payroll taxes, workers com- pensation insurance, liability insurance, health and welfare, pension, vacation, apprenticeship funds, and other direct costs, resulting from Federal, State, or local laws, as well as assessments or benefits required by lawful collective bargaining agreements.

The use of a labor classification which would increase the extra work cost will not be permitted unless the Contractor establishes the necessity for such additional costs. Labor costs for equip- ment operators and helpers shall be reported only when such costs are not included in the invoice for equipment rental. The labor cost for foremen shall be proportioned to all of their assigned work and only that applicable to extra work will be paid.

Nondirect labor costs, including superintendence, shall be considered part of the markup of Sec- tion 3-3.2.3 (a).

(b) Materials. The cost of materials reported shall be at invoice or lowest current price at which such materials are locally available and delivered to the job site in the quanti ties involved, plus sales tax, freight, and delivery.

The Agency reserves the right to approve materials and sources of supply, or to supply materials to the Contractor if necessary for the progress of the Work. No markup shall be applied to any material provided by the Agency.

(c) Tool and Equipment Rental. No payment will be made for the use of tools which have a replacement value of $200 or less.

Regardless of ownership, the rates and right-of-way delay factors to be used in determining rental and delay costs shall be the edition of the, “Labor Surcharge and Equipment Rental Rates” pub- lished by CALTRANS, current at the time of the actual use of the tool or equipment. The right-of- way delay factors therein shall be used as multipliers of the rental rates for determining the value of costs for delay to the Contractor and subcontractors, if any. The labor surcharge rates published therein are not a part of this contract.

The rental rates paid shall include the cost of fuel, oil, lubrication, supplies, small tools, necessary attachments, repairs and maintenance of any kind, depreciation, storage, insurance, and all inci- dentals. Necessary loading and transportation costs for equipment used on the extra work shall be included.

If equipment is used intermittently and, when not in use, could be returned to its rental source at less expense to the Agency than holding it at the Work site, it shall be returned, unless the Con- tractor elects to keep it at the Work site, at no expense to the Agency.

All equipment shall be acceptable to the Engineer, in good working condition, and suitable for the purpose for which it is to be used. Manufacturer’s ratings and approved modifications shall be used to classify equipment and it shall be powered by a unit of at least the minimum rating rec- ommended by the manufacturer.

Revised 6/15/17 Contract No. 5503-21 Page 70 of 122
The reported rental time for equipment already at the Work site shall be the duration of its use on the extra work. This time begins when equipment is first put into actual operation on the extra work, plus the time required to move it from its previous site and back, or to a closer site.

(d) Other Items. The Agency may authorize other items which may be required on the extra work, including labor, services, material, and equipment. These items must be diff erent in their nature from those required for the Work, and be of a type not ordinarily available from the Con- tractor or Subcontractors.

Invoices covering all such items in detail shall be submitted with the request for payment.

(e) Invoices. Vendors’ invoices for material, equipment rental and other expenditures shall be submitted with the request for payment. If the request for payment is not substantiated by invoices or other documentation, the Agency may establish the cost of the item involved at the lowest price which was current at the time of the report.

3-3.2.3 Markup.

(a) Work by Contractor. The following percentages shall be added to the Contractor's costs and shall constitute the markup for all overhead and profits:

1. Labor …………………………..…. 20

2. Materials …………………………. 15

3. Equipment Rental ………………. 15

4. Other Items and Expenditures … 15

To the sum of the costs and markups provided for in this section, 1 percent shall be added as compensation for bonding.

(b) Work by Subcontractor. When all or any part of the extra work is performed by a Sub- contractor, the markup established in Section 3-3.2.3(a) shall be applied to the Subcontractor's actual cost of such work. A markup of 10 percent on the first $5,000 of the subcontracted portion of the extra work and a markup of 5 percent on work added in excess of $5,000 of the subcon- tracted portion of the extra work may be added by the Contractor.

3-3.3 Daily Reports by Contractor. When the price for the extra work cannot be agreed upon, the Contractor shall submit a daily report to the Engineer on forms approved by the Agency.

Included are applicable delivery tickets, listing all labor, materials, and equipment involved for that day, and other services and expenditures when authorized. Payment for extra work will no t be made until such time that the Contractor submits completed daily reports and all supporting doc- uments to the Engineer. Failure to submit the daily report by the close of the next working day may waive any rights for that day. An attempt shall be made to reconcile the report daily, and it shall be signed by the Engineer and the Contractor. In the event of disagreement, pertinent notes shall be entered by each party to explain points which cannot be resolved immediately. Each party shall retain a signed copy of the report. Reports by Subcontractors or others shall be submitted through the Contractor.

The report shall:

1. Show names of workers, classifications, and hours worked.

2. Describe and list quantities of materials used.

Revised 6/15/17 Contract No. 5503-21 Page 71 of 122

3. Show type of equipment, size, i dentification number, and hours of operation, including loading and transportation, if applicable.

4. Describe other services and expenditures in such detail as the Agency may require.

3-4 CHANGED CONDITIONS. The Contractor shall promptly notify the Engineer of the fol- lowing Work site conditions (hereinafter called changed conditions), in writing, upon their discov- ery and before they are disturbed:

1. Subsurface or latent physical conditions differing materially from those represented in the Contract;

2. Unknown physical conditions of an unusual nature differing materially from those ordinarily encountered and generally recognized as inherent in work of the character being per- formed; and

3. Material differing from that represented in the Contract which the Contractor believes may be 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.

The Engineer will promptly investigate conditions which appear to be changed conditions. If the Engineer determines that conditions are changed conditions and they will materially affect perfor- mance time, the Contractor, upon submitting a written request, will be granted an extension of time subject to the provisions of 6-6.

If the Engineer determines that the conditions do not justify an adjustment in compensation, the Contractor will be notified in writing. This notice will also advise the Contractor of its obligation to notify the Engineer in writing if the Contractor disagrees.

The Contractor’s failure to give notice of changed conditions promptly upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection therewith.

The Contractor shall not be entitled to the payment of any additional compensation for any act, or failure to act, by the Engineer, including failure or refusal to issue a change order, or for the hap- pening of any event, thing, occurrence, or other cause, unless the Contractor shall have first given the Engineer due written notice of potential claim as hereinafter specified. Compliance with this section shall not be required as a prerequisite to notice provisions in Section 6-7.3 Contract Time Accounting, nor to any claim that is based on differences in measurement or errors of computation as to contract quantities. The written notice of potential claim for changed conditions shall be submitted by the Contractor to the Engineer upon their discovery a nd prior to the time that the Contractor performs the work giving rise to the potential claim. The Contractor’s failure to give written notice of potential claim for changed conditions to the agency upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection therewith.

The Contractor shall provide the City with a written document containing a description of the par- ticular circumstances giving rise to the potential claim, the reasons for which the Contractor be- lieves additional compensation m ay be due and nature of any and all costs involved within 20 working days of the date of service of the written notice of potential claim for changed conditions.

Verbal notifications are disallowed.

The potential claim shall include the following certification relative to the California False Claims Act, Government Code Sections 12650-12655.

Revised 6/15/17 Contract No. 5503-21 Page 72 of 122
“The undersigned certifies that the above statements are made in full cognizance of the California False Claims Act, Government Co de Sections 12650 -12655. The undersi gned further under- stands and agrees that this potential claim, unless resolved, must be restated as a claim in re- sponse to the City’s proposed final estimate in order for it to be further considered.”

Date: _________________________________

Company Name: ______________________________________________________________

The Contractor’s estimate of costs may be updated when actual costs are known. The Contractor shall submit substantiation of its actual costs to the Engineer within 20 working days after the affected work is completed. Failure to do so shall be sufficient cause for denial of any claim sub- sequently filed on the basis of said notice of potential claim.

It is the intention of this section that differences between the parties arising under and by virtue of the contract be brought to the attention of the Engineer at the earliest possible time in order that such matters be settled, if possible, or other appropriate action promptly taken.

3-5 DISPUTED WORK. The Contractor shall give the agency written notice of potential claim prior to commencing any disputed work. Failure to give said notice shall constitute a waiver of all claims in connection therewith. If the contractor and the agency are unable to reach agreement on disputed work, the Agency may direct the contractor to proceed with the work.

Prior to proceeding with dispute resolution pursuant to Public Contract Code provisions specified hereinafter, the contractor shall attempt to resolve all disputes informally through the following dispute resolution chain of command:

1. Project Inspector

2. Construction Manager

3. Deputy City Engineer, Construction Management & Inspection

4. City Engineer

5. City Manager

The Contractor shall s ubmit a complete report within 20 working days after completion of the disputed work stating its position on the claim, the contractual basis for the claim, along with all documentation supporting the costs and all other evidentiary materials. At each level of claim or appeal of claim the City will, within 10 working days of receipt of said claim or appeal of claim, review the Contractor’s report and respond with a position, request additional information or re- quest that the Contractor meet and present its report. When additional information or a meeting is requested the City will provide its position within 10 working days of receipt of said additional information or Contractor’s presentation of its report. The Contra ctor may appeal each level’s position up to the City Manager after which the Contractor may proceed under the provisions of the Public Contract Code.

The authority within the dispute resolution chain of command is limited to recommending a reso- lution to a claim to the City Manager. Actual approval of the claim is subject to the change order provisions in the contract.

(E) This section does not preclude a public entity from requiring arbitration of disputes under pri- vate arbitration or the Public Works Contract Arbitration Program, if mediation under this section does not resolve the parties’ dispute.
(3) Failure by the public entity to respond to a cla im from a contractor within the time periods described in this subdivision or to otherwise meet the time requirements of this section shall result in the claim being deemed rejected in its entirety. A claim that is denied by reason of the public entity’s failure to have responded to a claim, or its failure to otherwise meet the time requirements of this section, shall not constitute an adverse finding with regard to the merits of the claim or the responsibility or qualifications of the claimant.
(4) Amounts not paid in a timely manner as required by this section shall bear interest at 7 percent per annum.

(5) If a subcontractor or a lower tier subcontractor lacks legal standing to assert a claim against a public entity because privity of contract does not exist, the contractor may present to the public entity a claim on behalf of a subcontractor or lower tier subcontractor. A subcontractor may re- quest in writing, either on his or her own behalf or on behalf of a lower tier subcontractor, that the contractor present a claim for work which was performed by the subcontractor or by a lower tier subcontractor on behalf of the subcontractor. The subcontractor requesting that the claim be pre- sented to the public entity shall furnish reasonable documentation to support the claim. Within 45 days of receipt of this written request, the contractor shall notify the subcontractor in writing as to whether the contractor presented the claim to the public entity and, if the original contractor did not present the claim, provid e the subcontractor with a statement of the reasons for not having done so.

(e) The text of this section or a summary of it shall be set forth in the plans or specifications for any public works project that may give rise to a claim under this section.

(f) A waiver of the rights granted by this section is void and contrary to public policy, provided, however, that (1) upon receipt of a claim, the parties may mutually agree to waive, in writing, mediation and proceed directly to the commencement of a civil action or binding arbitration, as applicable; and (2) a public entity may prescribe reasonable change order, claim, and dispute resolution procedures and requirements in addition to the provisions of this section, so long as the contractual provisions do not conflict with or otherwise impair the timeframes and procedures set forth in this section.

(g) This section applies to contracts entered into on or after January 1, 2017.

(h) Nothing in this section shall impose liability upon a public entity that ma kes loans or grants available through a competitive application process, for the failure of an awardee to meet its con- tractual obligations.

(i) This section shall remain in effect only until January 1, 2020, and as of that date is repealed, unless a later enacted statute, that is enacted before January 1, 2020, deletes or extends that date.

In addition, all claims by Contractor for $375,000 or less shall be resolved in accordance with the procedures in the Public Contract Code, Division 2, Part 3, Chapter 1, Article 1.5 (commencing with Section 20104) which is set forth below

SECTION 4 – CONTROL OF MATERIALS

4-1 MATERIALS AND WORKMANSHIP.

4-1.1. General. All materials, parts, and equipment furnished by the Contractor in the Work shall be new, high grade, and free from defects. Quality of work shall be in accordance with the gener- ally accepted standards. Material and work quality shall be subject to the Engineer’s approval.

Materials and work quality not conforming to the requirements of the Specifications shall be con- sidered defective and will be subject to rejection. Defective work or material, whether in place or not, shall be removed immediately from the site by the Contractor, at its expense, when so di- rected by the Engineer.

If the Contractor fails to replace any defective or damaged work or material after reasonable no- tice, the Engineer may cause such work or materials to be replaced. The replacement expense will be deducted from the amount to be paid to the Contractor.

Used or secondhand materials, parts, and equipment may be used only if permitted by the Spec- ifications.

4-1.2 Protection of Work and Materials. The Contractor shall provide and maintain storage facilities and employ such measures as will preserve the specified quality and fitness of materials to be used in the Work. Stored materials shall be reasonably accessible for inspection. The Con- tractor shall also adequately protect n ew and existing work and all items of equipment for the duration of the Contract.

The Contractor shall not, without the Agency’s consent, assign, sell, mortgage, hypothecate, or remove equipment or materials which have been installed or delivered and which may be neces- sary for the completion of the Contract.

4-1.3 Inspection Requirements.

4-1.3.1 General. Unless otherwise specified, inspection is required at the source for such typical materials and fabricated items as bituminous paving mixtures, structural concrete, metal fabrica- tion, metal casting, welding, concrete pipe manufacture, protective coating application, and similar shop or plant operations.

Steel pipe in sizes less than 18 inches and vitrified clay and cast iron pipe in all sizes are accepta- ble upon certification as to compliance with the Specifications, subject to sampling and testing by the Agency. Standard items of equipment such as electric motors, conveyors, elevators, plumbing fixtures, etc., are subject to inspection at the job site only. Special items of equipment such as designed electrical panel boards, large pumps, sewage plant equipment, etc., are subject to in- spection at the source, normally only for performance testing. The Specifications may require inspection at the source for other items not typical of those listed in this section.

The Contractor shall provide the Engineer free and safe access to any and all parts of work at any time. Such free and safe access shall include means of safe access and egress, ventilation, lighting, shoring, dewatering and all elements pertaining to the safety of persons as contained in the State of California, California Code of Regulations, Title 8, Industrial Relations, Chapter 4, Division of Industrial Safety, Subchapter 4, Construction Safety Orders and such other safety

Revised 6/15/17 Contract No. 5503-21 Page 79 of 122
regulations as may apply. Contractor shall furnish Engineer with such information as may be nec- essary to keep the Engineer fully informed regarding progress and manner of work and character of materials. Inspection or testing of the whole or any portion of the work or materials incorporated in the work shall not relieve Contractor from any obligation to fulfill this Contract.

4-1.3.2 Inspection of Materials Not Locally Produced. When the Contractor intends to pur- chase materials, fabricated products, or equipment from sources located more than 50 miles out- side the geographical limits of the Agency, an inspector or accredited testing laboratory (approved by the Engineer), shall be engaged by the Contractor at its expense, to inspect the materials, equipment or process. This approval shall be obtained before producing any material or equip- ment. The inspector or representative of the testing laboratory shall judge the materials by the requirements of the Plans and Specifications. The Contractor shall forward reports required by the Engineer. No material or equipment shall be shipped nor shall any processing, fabrication or treatment of such materials be done without proper inspection by the approved agent. Approval by said agent s hall not relieve the Contractor of responsibility for complying with the Contract requirements.

4-1.3.3 Inspection by the Agency. The Agency will provide all inspection and testing laboratory services within 50 miles of the geographical limits of the Agency. For private contracts, all costs of inspection at the source, including salaries and mileage costs, shall be paid by the permittee.

4-1.4 Test of Material. Before incorporation in the Work, the Contractor shall submit samples of materials, as the Engi neer may require, at no cost to the Agency. The Contractor, at its ex- pense, shall deliver the materials for testing to the place and at the time designated by the Engi- neer. Unless otherwise provided, all initial testing will be performed u nder the direction of the Engineer, and at no expense to the Contractor. If the Contractor is to provide and pay for testing, it will be stated in the Specifications. For private contracts, the testing expense shall be borne by the permittee.

The Contractor shall notify the Engineer in writing, at least 15 days in advance, of its intention to use materials for which tests are specified, to allow sufficient time to perform the tests. The notice shall name the proposed supplier and source of material.

If the notice of intent to use is sent before the materials are available for testing or inspection, or is sent so far in advance that the materials on hand at the time will not last but will be replaced by a new lot prior to use on the Work, it will be the Contractor’s responsibility to renotify the Engineer when samples which are representative may be obtained.

Except as specified in these Provisions, the Agency will bear the cost of testing of locally produced materials and/or on-site workmanship where the results of such tests meet or exceed the require- ments indicated in the Standard Specifications, Technical Specification, and any Supplemental Provisions. The cost of all other tests shall be borne by the Contractor.

At the option of the Engineer, the source of supply of each of the materials shall be approved by the Engineer before the delivery is started. All materials proposed for use may be inspected or tested at any time during their preparation and use. If, after incorporating such materials into the Work, it is found that sources of supply that have been approved do not furnish a uniform product, or if the product from any source proves unacceptable at any time, the Contractor shall furnish approved material from other approved sources. If any produc t proves unaccept able after im- proper storage, handling or for any other reason it shall be rejected, not incorporated into the work and shall be removed from the project site all at the Contractor’s expense.

Revised 6/15/17 Contract No. 5503-21 Page 80 of 122

Compaction tests may be made by the Engineer and all costs for tests that meet or exceed the requirements of the specifications shall be borne by the Agency. Said tests may be made at any place along the work as deemed necessary by the Engineer. The costs of any retests made nec- essary by noncompliance with the specifications shall be borne by the Contractor.

4-1.5 Certification. The Engineer may waive materials testing requirements of the Specifica- tions and accept the manufacturer’s written certification that the materials to be supplied meet those requirements. Material test data may be required as part of the certification.

4-1.6 Trade Names or Equals. The Contractor may supply any of the materials specified or offer an equivalent. The Engineer shall determine whether the material offered is equivalent to that specified. Adequate time shall be allowed for the Engineer to make this determination.

Whenever any particular material, process, or equipment is indicated by patent, proprietary or brand name, or by name of manufacturer, such wording is used for the purpose of facilitating its description and shall be deemed to be follow ed by the words or equal. A listing of materials is not intended to be comprehensive, or in order of preference. The Contractor may offer any mate- rial, process, or equipment considered to be equ ivalent to that indicated. The substantiation of offers shall be submitted as provided in the contract documents.

The Contractor shall, at its expense, furnish data concerning items offered by it as equivalent to those specified. The Contractor shall have the material tested as required by the Engineer to determine that the quality, strength, physical, chemical, or other characteristics, including durabil- ity, finish, efficiency, dimensions, service, and suitability are such that the item will fulfill its i n- tended function.

Test methods shall be subject to the approval of the Engineer. Test results shall be reported promptly to the Engineer, who will evaluate the results and determine if the substitute item is equivalent. The Engineer’s findings shall be fi nal. Installation and use of a substitute item shall not be made until approved by the Engineer.

If a substitute offered by the Contractor is not found to be equal to the specified material, the Contractor shall furnish and install the specified material.

The specified Contract completion time shall not be affected by any circumstance developing from the provisions of this section.

The Contractor is responsible for the satisfactory performance of substituted items. If, in the sole opinion of the Engineer, the substitution is determined to be unsatisfactory in performance, ap- pearance, durability, compatibility with associated items, availability of repair parts and suitability of application the Contractor shall remove the substituted item and replace it w ith the originally specified item at no cost to the Agency.

4-1.7 Weighing and Metering Equipment. All scales and metering equipment used for propor- tioning materials shall be inspected for accuracy and certified within the past 12 months by the State of California Bureau of Weights and Measures, by the County Director or Sealer of Weights and Measures, or by a scale mechanic registered with or licensed by the County.

Revised 6/15/17 Contract No. 5503-21 Page 81 of 122
The accuracy of the work of a scale service agency, except as stated herein, shall meet t he standards of the California Business and Professions Code and the California Code of Regula- tions pertaining to weighing devices. A certificate of compliance shall be presented, prior to oper- ation, to the Engineer for approval and shall be renewed whenev er required by the Engineer at no cost to the Agency.

All scales shall be arranged so they may be read easily from the operator’s platform or area. They shall indicate the true net weight without the application of any factor. The figures of the scales shall be clearly legible. Scales shall be accurate to with in 1 percent when tested with the plant shut down. Weighing equipment shall be so insulated against vibration or moving of other oper- ating equipment in the plant area that the error in weighing with the entire plant running will not exceed 2 percent for any setting nor 1.5 percent for any batch.

4-1.8 Calibration of Testing Equipment. Testing equipment, such as, but not limited to pres- sure gages, metering devices, hydraulic systems, force (load) measuring instruments, and strain- measuring devices shall be calibrated by a testing agency acceptable to the Engineer at intervals not to exceed 12 months and following repairs, modification, or relocation of the equipment. Cal- ibration certificates shall be provided when requested by the Engineer.

4-1.9 Constructi on Materials Dispute Resolution (Soils, Rock Materials, Concrete, Mortar and Related Materials, Masonry Materials, Bituminous Materials, Rock Products, and Mod- ified Asphalts). In the interest of safety and public value, whenever credible evidence arises to contradict the test values of materials, the Agency and the Contractor will initiate an immediate and cooperative investigation. Test values of materials are results of the materials’ tests, as de- fined by these Specifications or by the special provisions, required to accept the Work. Credible evidence is process observations or test values gathered using industry accept ed practices. A contradiction exists whenever test values or process observations of the same or similar materials are diverse enough such that the work acceptance or performance becomes suspect. The inves- tigation shall allow access to all test results, pr ocedures, and facilities relevant to the disputed work and consider all available information and, when necessary, gather new and additional in- formation in an attempt to determine the validity, the cause, and if necessary, the remedy to the contradiction. If the cooperative investigation reaches any resolution mechanism acceptable to both the Agency and the Contractor, the contradiction shall be considered resolved and the co- operative investigation concluded. Whenever the cooperative investigation is unable to reach res- olution, the investigation may then either conclude without resolution or continue by written noti- fication of one party to the other requesting the implementation of a resolution process by com- mittee. The continuance of the investigation shall be contingent upon recipient’s agreement and acknowledged in writing within 3 calendar days after receiving a request. Without acknowledge- ment, the investigation shall conclude without resolution. The committee shall consist of three State of California Registered Civil Engineers. Within 7 calendar days after the written request notification, the Agency and the Contractor will each select one engineer. Within 14 calendar days of the written request notification, the two selected engineers will select a third engineer. The goal in selection of the third member is to complement the profess ional experience of the first two engineers. Should the two engineers fail to select the third engineer, the Agency and the Con- tractor shall each propose 2 engineers to be the third member within 21 calendar days after the written request notification. The first two engineers previously selected shall then select one of the four proposed engineers in a blind draw. The committee shall be a continuance of the coop- erative investigation and will re -consider all available information and if necessary, gather new and additional information to determine the validity, the cause, and if necessary, the remedy to the contradiction. The committee will focus upon the performance adequacy of the material(s) using standard engineering principles and practices and to ensure public value, the committee

Revised 6/15/17 Contract No. 5503-21 Page 82 of 122
may provide engineering recommendations as necessary. Unless otherwise agreed, the commit- tee will have 30 calendar days from its formation to complete their review and submit their find- ings. The final resolution of the committee shall be by majority opinion, in writing, stamped and signed. Should the final resolution not be unanimous, the dissenter may attach a written, stamped, and signed minority opinion. Once started, the resolution process by committee shall continue to full conclusion unless:

1. Within 7 days of the formation of the committee, the Agency and the Contractor reach an acceptable resolution mechanism; or

2. Within 14 days of the formation of the committee, the initiating party withdraws its written notification and agrees to bear all investigative related costs thus far incurred; or

3. At any point by the mutual agreement of the Agency and the Contractor. Unless otherwise agreed, the Contractor shall bear and maintain a record for all the investigative costs until resolution. Should the investigation discover assignable causes for the contradiction, the assignable party, the Agency or the Contractor, shall bear all costs associated with the investigation. Should assignable causes for the contradiction extended to both parties, the investigation will assign costs cooperatively with each party or when necessary, equally.

Should the investigation substantiate a contradiction without assignable cause, the inves- tigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation be unable to substantiate a contradiction, the initiator of the investigation shall bear all investigative costs. All claim notification requirements of the contract pertain- ing to the contradiction shall be suspended until the investigation is concluded.

4-2 MATERIALS TRANSPORTATION, HANDLING AND STORAGE. The Contractor shall order, purchase, transport, coordinate delivery, accept delivery, confirm the quantity and quality received, prepare storage area(s), store, handle, protect, move, relocate, remove and dispose excess of all materials used to accomplish the Work. Materials shall be delivered to the site of the work only during working hours, as defined in Section 6-7.2, and shall be accompanied by bills of lading that shall clearly state for each delivery: the name of the Contractor as consignee, the project name and number, address of delivery and name of consignor and a description of the material(s) shipped. Prior to storage of any materials which have been shipped to or by the Contractor to any location within the Agency’s boundaries the Contractor shall provide the Engi- neer a copy of lease agreements for each property where such materials are stored. The lease agreement shall clearly state the term of the le ase, the description of materials allowed to b e stored and shall provide for the removal of the materials and restoration of the storage site within the time allowed for the Work. All such storage shall conform to all laws and ordinances that may pertain to the materials stored and to preparation of the storage site and the location of the site on which the materials are stored. Loss, damage or deterioration of all stored materials shall be the Contractor’s responsibility. Conformance to the requirements of this section, both within and outside the limits of work are a part of the Work. The Engineer shall have the right to verify the suitability of materials and their proper storage at any time during the Work.

Revised 6/15/17 Contract No. 5503-21 Page 83 of 122
SECTION 5 – UTILITIES

5-1 LOCATION. The Agency and affected utility companies have, by a search of known rec- ords, endeavored to locate and indicate on the Plans, all utilities which exist within the limits of the work. However, the accuracy and/or completeness of the nature, size and/or location of utili- ties indicated on the Plans is not guaranteed.

Where underground main distribution conduits such as water, gas, sewer, electric power, tele- phone, or cable television are shown on the Plans, the Contractor shall assume that every prop- erty parcel will be served by a service connection for each type of utility.

As provided in Section 4216 of the California Government Code, at least 2 working days prior to commencing any excavation, the Contractor shall contact the regional notification center (Under- ground Service Alert of Southern California) and obtain an inquiry identification number.

The California Department of Transportation is not required by Section 4216 to become a member of the regional notification center. The Contractor shall contact it for lo cation of its subsurface installations.

The Contractor shall determine the location and depth of all utilities, including service connections, which have been marked by the respective owners and which may affect or be affected by its operations. If no pay item is provided in the Contract for this work, full compensation for such work shall be considered as included in the prices bid for other items of work.

5-2 PROTECTION. The Contractor shall not interrupt the service function or disturb the sup- port of any utility without authority from the owner or order from the Agency. All valves, switches, vaults, and meters shall be maintained readily accessible for emergency shutoff.

Where protection is required to ensure support of utilities located as shown on th e Plans or in accordance with Section 5-1, the Contractor shall, unless otherwise provided, furnish and place the necessary protection at its expense.

Upon learning of the existence and location of any utility omitted from or shown incorrectly on the Plans, the Contractor shall immediately notify t he Engineer in writing. When authorized by the Engineer, support or protection of the utility will be paid for as provided in Section 3-2.2.3 or 3-3.

The Contractor shall immediately notify the Engineer and the utility owner if any utility is disturbed or damaged. The Contractor shall bear the costs of repair or replacement of any utility damaged if located as noted in Section 5-1.

When placing concrete around or contiguous to any non-metallic utility installation, the Contractor shall at its expense:

1. Furnish and install a 2 inch cushion of expansion joint material or other similar resilient material; or

2. Provide a sleeve or other opening which will result in a 2 inch minimum -clear annular space between the concrete and the utility; or

3. Provide other acceptable means to prevent embedment in or bonding to the concrete.

Revised 6/15/17 Contract No. 5503-21 Page 84 of 122
Where concrete is used for backfill or for structures which would result in embedment, or partial embedment, of a metallic utility installation; or where the coating, bedding or other cathodic pro- tection system is exposed or damaged by the Contractor’s operations, the Contractor shall notify the Engineer and arrange to secure the advice of the affected utility owner regarding the proce- dures required to maintain or restore the integrity of the system.

5-3 REMOVAL. Unless otherwise specified, the Contractor shall remove all interfering por- tions of utilities shown on the Plans or indicated in the Bid documents as “abandoned” or “to be abandoned in place”. Before starting removal operations, the Contractor shall ascertain from the Agency whether the abandonment is complete, and the costs involved in the removal and disposal shall be included in the Bid for the items of work necessitating such removals.

5-4 RELOCATION. When feasible, the owners responsible for utilities within the area affected by the Work will complete their necessary installations, relocations, repairs, or replacements be- fore commencement of work by the Contractor. When the Plans or Specifications indicate that a utility installation is to be relocated, altered, or constructed by others, the Agency will conduct all negotiations with the owners and work will be done at no cost to the Contractor, except for man- hole frame and cover sets to be brought to grade as provided in the Standard Specifications for Public Works Construction, Section 301-1.6, 2006 current Edition. Utilities which are relocated in order to avoid interference shall be protected in their position and the cost of such protection shall be included in the Bid for the items of work necessitating such relocation.

After award of the Contract, portions of utilities which are found to interfere with the Work will be relocated, altered or reconstructed by the owners, or the Engineer may order changes in the Work to avoid interference. Such changes will be paid for in accordance with Section 3-2.

When the Plans or Specifications provide for the Contractor to alter, relocate, or reconstruct a utility, all costs for such work shall be included in the Bid for the items of work necessitating such work. Temporary or permanent relocation or alteration of utilities requested by the Contractor for its convenience shall be its responsibility and it shall make all arrangements and bear all costs.

The utility owner will relocate service connecti ons as necessary within the limits of the Work or within temporary construction or slope easements. When directed by the Engineer, the Contractor shall arrange for the relocation of service connections as necessary between the meter and prop- erty line, or between a meter and the limits of temporary construction or slope easements. The relocation of such service connections will be paid for in accordance with provisions of Section 3-

3. Payment will include the restoration of all existing improvements which ma y be affected thereby. The Contractor may agree with the owner of any utility to disconnect and reconnect in- terfering service connections. The Agency will not be involved in any such agreement.

In conformance with Section 5-6 the Contractor shall coordinate the work with utility agencies and companies. Prior to the installation of any and all utility structures within the limits of work by any utility agency or company, or its contractor, the Contractor shall place all curb or curb and gutter that is a part of the work and adjacent to the location where such utility structures are shown on the plans and are noted as being located, relocated or are otherwise shown as installed by others.

In order to minimize delays to the Contractor caused by the failure of other parties to relocate utilities that interfere with the construction, the Contractor, upon the Engineer’s approval, may be permitted to temporarily omit the portion of work affected by the utility. If such temporary omission is approved by the Engineer the Contractor shall place survey or other physical control markers sufficient to locate the curb or curb and gutter to the satisfaction of the utility agency or company .

Such temporary omission shall be for the Contractor’s convenience and no additional compensa- tion will be allowed therefore or for additional work, materials or delay associated with the tempo- rary omission. The portion thus omitted shall be constructed by the Contractor immediately fol- lowing the relocation of the utility involved unless otherwise directed by the Engineer.

5-5 DELAYS. The Contractor shall notify the Engineer of its construction schedule insofar as it affects the protection, removal, or relocation of utilities. Said notification shall be included as a part of the construction schedule required in Section 6-1. The Contractor shall notify the Engineer in writing of any subsequent changes in the construction schedule which will affect the time avail- able for protection, removal, or relocation of utilities.

The Contractor will no t be entitled to damages or additional payment for delays attributable to utility relocations or alterations if correctly located, noted, and completed in accordance with Sec- tion 5-1.

The Contractor may be given an extension of time for unforeseen delays attributable to unrea- sonably protracted interference by utilities in performing work correctly shown on the Plans.

The Agency will assume responsibility for the timely removal, relocation, or protection of existing main or trunkline utility facilities within the area affected by the Work if such utilities are not iden- tified in the Contract Documents. The Contractor will not be assessed liquidated damages for any delay caused by failure of Agency to provide for the timely removal, relocation, or protection of such existing facilities.

If the Contractor sustains loss due to delays attributable to interferences, relocations, or altera- tions not covered by Section 5-1, which could not have been avoided by the judicious handling of forces, equipment, or plant, there shall be paid to the Contractor such amount as the Engineer may find to be fair and reasonable compensation for such part of the Contractor’s actual loss as was unavoidable and the Contractor may be granted an extension of time.

5-6 COOPERATION. When necessary, the Contractor shall so conduct its operations as to permit access to the Work site and provide time for utility work to be accomplished during the progress of the Work.

SECTION 6 – PROSECUTION, PROGRESS,

AND ACCEPTANCE OF THE WORK

6-1 CONSTRUCTION SCHEDULE AND COMMENCEMENT OF WORK. Except as other- wise provided herein and unless otherwise prohibited by permits from other agencies as may be required by law the Contractor shall begin work within ten (10) calendar days after receipt of the "Notice to Proceed".

6-1.1 Pre-Construction Meeting. After, or upon, notification of contract award, the Engineer will set the time and location for the Preconstruction Meeting. Attendance of the Contractor’s man- agement personnel responsible for the management, administration, and execution of the project is mandatory for the meeting to be convened. Failure of the Contractor to have the Contractor’s responsible project personnel attend the Preconstruction Meeting will be grounds for default by Contractor per Section 6-4. No separate payment will be made for the Contractor’s attendance at the meeting. The notice to proceed will only be issued on or after the completion of the precon- struction meeting.

6-1.1.1 Baseline Construction Schedule Submittal. The Contractor shall submit the Baseline Construction Schedule per the submittal requirements of Section 2-5.3. The submittal of the Base- line Construction Schedule shall include each item and element of Sections 6-1.2 through 6-1.2.9 and shall be on hard (paper) copy and electronic media conforming to Section 6-1.3.3 Electronic Media.

6-1.2 Preparation and Review of the Baseline Construction Schedule. The Contractor shall prepare the Baseline Construction Schedule as a Critical Path Method (CPM) Schedule in the precedence diagram method (activity-on-node) format. The Baseline Construction Schedule shall depict a workable plan showing the sequence, duration, and interdependence of all activities re- quired to represent the complete performance of all project work as well as periods where work is precluded. The Baseline Construction Schedule shall begin with the projected date of issuance of the notice to proceed and conclude with the date of final completion per the contract duration.

The Baseline Construction Schedule shall include detail of all project phasing, staging, and se- quencing, including all milestones necessary to define beginning and ending of each phase or stage.

6-1.2.1 Time-Scaled Network Diagram. As a part of the Baseline Construction Schedule the Contractor shall prepare and submit to the Engineer a com plete time-scaled network diagram showing all of the activities, logic relationships, and milestones comprising the schedule.

6-1.2.2 Tabular Listing. As a part of the Baseline Construction Schedule the Con tractor shall prepare and submit to the Engineer a tabular listing of all of the activities, showing for each activity the identification number, the description, the duration, the early start, the early finish, the late start, the late finish, the total f loat, and all predecessor and successor activitie s for the activity described.

6-1.2.3 Bar Chart. As a part of the Baseline Construction Schedule the Contractor shall prepare and submit to the Engineer a chart showing individual tasks and their durations arranged with the tasks on the vertical axis and duration on the horizontal axis. The bar chart shall use differing texture patterns or distinctive line types to show the critical path.

Revised 6/15/17 Contract No. 5503-21 Page 87 of 122
6-1.2.4 Schedule Software. The Contractor shall use commercially available software equal to the Windows compatible “Suretrak” program by Primavera or “Project” program by Microsoft Cor- poration to prepare the Baseline Construction Schedule and all updates thereto. The Contractor shall submit source files and PDFs electronically to the Agency in a format readable by a Microsoft Windows 10 system.

6-1.2.5 Schedule Activities. Except for submittal activities, activity durations shall not be shorter than 1 working day nor longer than 15 working days, unless specifically and individually allowed by the Engineer. The Baseline Construction Schedule shall include between 100 and 500 activi- ties, including submittals, interfaces between utility companies and other agencies, project mile- stones and equipment and material deliveries. The n umber of activities will be sufficient, in the judgment of the Engineer, to communicate the Contracto r’s plan for project execution, to accu- rately describe the project work, and to allow monitoring and evaluation of progress and of time impacts. Each activity’s description shall accurately define the work planned for the activity and each activity shall have recognizable beginning and end points.

6-1.2.6 Float. Float or slack time within the schedule is available without charge or compensation to whatever party or contingency first exhausts it.

6-1.2.7 Restraints to Activities. Any submittals, utility interfaces, or any furnishing of Agency supplied materials, equipment, or services, which may impact any activity’s construction shall be shown as a restraint to those activities. Time periods to accommodate the review and correction of submittals shall be included in the schedule.

6-1.2.8 Late Completion. A Baseline Construction Schedule showing a project duration longer than the specified contract duration will not be acceptable and will be grounds for determination of default by Contractor, per Section 6-4.

6-1.2.9 Early Completion. The Baseline Construction Schedule will show the Contractor’s plan to support and maintain the project for the entire contractual time span of the project. Should the Contractor propose a project duration shorter than contract duration, a complete Baseline Con- struction Schedule must be submitted, reflecting the shorter duration, in complete accordance with all schedule requirements of Section 6-1. The Engineer may choose to accept the Contrac- tor’s proposal of a project duration shorter than the duration specified; provided the Agency is satisfied the shortened Baseline Construction Schedule is reasonable and the Agency and all other entities, public and private, which interface with the project are able to support the provisions of the shortened Baseline Construction Schedule. The Agency’s acceptance of a shortened du- ration project will be confirmed through the execution of a cont ract change order revising the project duration and implementing all contractual requirements includi ng liquidated damages in accordance with the revised duration.

6-1.2.10 Engineer’s Review. The Construction Schedule is subject to the review of the Engineer.

The Engineer’s determination that the Baseline Construction Schedule proposed by the Contrac- tor complies with the requirements of these supplemental provisions shall be a condition prece- dent to issuance of the Notice to Proceed by the Engineer. If the Engineer determines that the Construction Schedule does not meet the requirements of these specifications the Contractor shall correct the Construction Schedule to meet these specifications and resubmit it to the Engi- neer. Failure of the Contractor to obtain the Engineer’s determination that the initial Construction Schedule proposed by the Contractor complies with the requirements of these supplemental pro- visions within thirty (30) working da ys after the date of the preconstruction meeting shall be

Revised 6/15/17 Contract No. 5503-21 Page 88 of 122
grounds for termination of the contract per Section 6-4. Days used by the Engineer to review the initial Construction Schedule will not be included in the 30 working days.

The Engineer will review and return to the Contractor, with any comments, the Baseline Construc- tion Schedule within 15 working days of submittal. The Baseline Construction Schedule will be returned marked as per Sections 6-1.2.10.1 through 6-1.2.10.3.

6-1.2.10.1 “Accepted.” The Contractor may proceed with the project work upon issuance of the Notice to Proceed and will receive payment for the schedule in accordance with Section 6-1.8.1.

6-1.2.10.2 “Accepted with Comments.” The Contractor may proceed with the project work upon issuance of the Notice to Proceed. The Contractor must resubmit the schedule incorporating the comments prior to receipt of payment per Section 6-1.8.1.

6-1.2.10.3 “Not Accepted.” The Contractor must resubmit the schedule incorporating the cor- rections and changes of the comments prior to receipt of payment per Section 6-1.8.1. The Notice to Proceed will not be issued by the Engineer if the changes of the comments are not submitted as required hereinbefore and marked “Accepted” or “Accepted with Comments” by the Engineer.

The Contractor, at the sole option of the Engineer, may be considered as having defaulted the contract under the provisions of Section 6-4 DEFAULT BY CONTRACTOR if the changes of the comments are not submitted as required hereinbefore and marked “Accepted” by the Engineer.

6-1.3 Preparation of Schedule Updates and Revisions. The Contractor shall meet with the Engineer during the last week of each month to agree upon each activity’s schedule status and shall submit monthly updates of the Baseline Construction Schedule confirming the agreements no later than the fifth working day of the following month. The most recent version of the schedule shall be provided at each Project Meeting. The monthly update will be submitted on hard (paper) copy and electronically per the submittal requirements of Section 2-5.3 and will include each item and element of Sections 6-1.2 through 6-1.2.9 and 6-1.3.1 through 6-1.3.6. Acceptable updates to the Baseline Construction schedule shall be a condition of payment.

6-1.3.1 Actual Activity Dates. The actual dates each activity was started and/or completed dur- ing the month. After first reporting an actual date, the Contractor shall not change that actual date in later updates without specific notification to the Engineer with the update.

6-1.3.2 Activity Percent Complete. For each activity underway at the end of the month, the Contractor shall report the percentage determined by the Engineer as complete for the activity.

6-1.3.3 List of Changes. A list of all changes made to the activities or to the interconnecting logic, with an explanation for each change.

6-1.3.4 Change Orders. Each monthly update will include the addition of the network revisions reflecting the change orders approved in the previous month. The network revisions will be as agreed upon during the review and acceptance of the Contractor’s change orders.

6-1.3.5 Bar Chart. Each monthly update will include a chart showing individual tasks and their durations arranged with the tasks on the vertical axis and duration on the horizontal axis. The bar chart shall use differing texture patterns or distinctive line types to show the critical path.

6-1.4 Engineer’s Review of Updated Construction Schedule. The Engineer will review and return the Updated Construction Schedule to the Contractor, with any comments, within 5 working

Revised 6/15/17 Contract No. 5503-21 Page 89 of 122
days of submittal. The Updated Construction Schedule will be returned marked as per Sections 6-1.4.1 through 6-1.4.3. Any Updated Construction Schedule marked “Accepted with Comments” or “Not Accepted” by the Engineer will be returned to the Contractor for correction. Upon resub- mittal the Engineer will review and return the resubmitted Updated Construction Schedule to the Contractor, with any comments, within 5 working days. Failure of the Contractor to submit a monthly updated construction schedule will invoke the same consequences as the Engineer re- turning a monthly updated construction schedule marked “Not Accepted”.

6-1.4.1 “Accepted.” The Contractor may proceed with the project work and will receive payment for the schedule in accordance with Section 6-1.8.2.

6-1.4.2 “Accepted with Comments.” The Contractor may proceed with the project work. The Contractor must resubmit the Updated Construction Schedule to the Engineer incorporating the corrections and changes noted in the Engineer’s comments prior to receipt of payment per Sec- tion 6-1.8.2.

6-1.4.3 “Not Accepted.” The Contractor must resubmit the Updated Construction Schedule to the Engineer incorporating the corrections and changes noted in the Engineer’s comments prior to receipt of payment per Section 6-1.8.2. The Contractor, at the sole option of the Engineer, may be considered as having defaulted the contract under the provisions of Section 6-4 DEFAULT BY CONTRACTOR if the changes of the comments are not submitted and marked “Accepted” by the Engineer before the last day of the month in which the Updated Construction Schedule is due. If the Contractor fails to submit the correc ted Updated Construction Schedule as required herein the Contractor may elect to proceed with the project at its own risk. Should the Contractor elect not to proceed with the project, any resulting delay , impact, or disruption to the project will be the Contractor’s responsibility.

6-1.5 Late Completion or Milestone Dates. Should the Schedule Update indicate a completion or contractually required milestone date later than the properly adjusted contract or milestone duration, the Agency may withhold Liquidated Damages for the number of days late. Should a subsequent “Accepted” Schedule Update remove all or a portion of the delay, all or the allocated portion of the previously held Liquidated Damages shall be released in the monthly payment to the Contractor immediately following the “Accepted” schedule.

6-1.6 Interim Revisions. Should the actual or projected progress of the work become substan- tially different from that depicted in the Project Schedule, independently of and prior to the next monthly update, the Contractor will submit a revised Baseline Construction Schedule, with a list and explanation of each change made to the schedule. The Revised Construction Schedule will be submitted per the submittal requirements of Section 2 -5.3 and per the schedule review and acceptance requirements of Section 6-1, including but not limited to the acceptance and payment provisions. As used in this section “substantially different” means a time variance greater than 5 percent of the number of days of duration for the project.

6-1.7 Final Schedule Update. The Contractor shall prepare and submit a final schedule update when one hundred percent of the construction work is completed. The Contractor’s Final Sched- ule Update must accurately represent the actual dates for all activities. The final schedule update shall be prepared and reviewed p er Sections 6-1.3 Preparation of Schedule Updates and Revi- sions and 6-1. 4 Engineer’s Review of Updated Construction Schedule. Acceptance of the final schedule update is required for completion of the project and release of any and all funds retained per Section 9-3.2.

6-1.8 Measurement and Payment.

6-1.8.1 Measurement and Payment of Construction Schedule. The Contractor’s preparation, revision and maintenance of the Construction Schedule are incidental to the work and no separate payment will be made therefor.

6-2 PROSECUTION OF WORK. To minimize public inconvenience and possible hazard and to restore street and other work areas to their original condition and state of usefulness as soon as practicable, the Contractor shall diligently prosecute the Work to completion. If the Engineer determines that the Contractor is failing to prosecute the Work to the proper extent, the Contractor shall, upon orders from the Engineer, immediately take steps to remedy the situation. All costs of prosecuting the Work as described herein shall be included in the Contractor’s Bid. Should the Contractor fail to take the necessary steps to fully accomplish said purposes, after orders of the Engineer, the Engineer may suspend the work in whole or part, until the Contractor takes said steps.

As soon as possible under the provisions of the Specifications, the Contractor shall backfill all excavations and restore to usefulness all improvements existing prior to the start of the Work.

If Work is suspended through no fault of the Agency, all expenses and losses incurred by the Contractor during such suspensions shall be borne by the Contractor. If the Contractor fails to properly provide for public safety, traffic, and protection of the Work during periods of suspension, the Agency may elect to do so, and deduct the cost thereof from monies due the Contractor. Such actions will not relieve the Contractor from liability.

6-2.1 Order of Work. The work to be done shall consist of furnishing all labor, equipment and materials, and performing all operations necessary to complete the Project Work as shown on the Project Plans and as specified in the Specifications. The work includes rehabilitation of sewer pipeline, including installation of cured-in-place pipe (CIPP) and spiral wound lining systems, re- instatement of laterals, traffic control plans and traffic control devices, and other miscellaneous related work items. Refer to Appendix B for detailed information.

6-2.2 Project Meetings. The Engineer will establish the time and location of weekly Project Meetings. The Contractor’s Representative and any key subcontractors shall attend each Project Meeting. The Contractor is to provide a 3-week look ahead of work to be performed. The Project Representative shall be the individual determined under Sect ion 7-6, “The Contractor’s Repre- sentative”. No separate payment for attendance of the Contractor, the Contractor’s Representa- tive or any other employee or subcontractor or subcontractor’s employee at these meetings will be made. The Contractor shall provide the most recent construction schedule and a 3-week look ahead update at each Project Meeting.

6-3 SUSPENSION OF WORK.

6-3.1 General. The Work may be suspended in whole or in part when determined by the Engi- neer that the suspension is necessary in the interest of the Agency. The Contractor shall comply immediately with any written order of the Engineer. Such suspension shall be without liability to the Contractor on the part of the Agency except as otherwise specified in Section 6-6.3.

6-3.2 Archaeological and Paleontological Discoveries. If discovery is made of items of ar- chaeological or paleontological interest, the Contractor shall immediately cease excavation in the

Revised 6/15/17 Contract No. 5503-21 Page 91 of 122
area of discovery and shall not continue until ordered by the Engineer. When resumed, excavation operations within the area of discovery shall be as directed by the Engineer.

Discoveries which may be encountered may include, but not be limited to, dwelling sites, stone implements or other artifacts, animal bones, human bones, and fossils.

The Contractor shall be entitled to an extension of time and compensation in accordance with the provisions of Section 6-6.

6-4 DEFAULT BY CONTRACTOR. If the Contractor fails to begin delivery of material and equipment, to commence the Work within the t ime specified, to maintain the rate of delivery of material, to execute the Work in the manner and at such locations as specified, or fails to maintain the Work schedule which will insure the Agency’s interest, or, if the Contractor is not carrying out the intent of the Contract, the Agency may serve written notice upon the Contractor and the Surety on its Faithful Performance Bond demanding satisfactory compliance with the Contract.

The Contract may be canceled by the Board without liability for damage, w hen in the Board’s opinion the Contractor is not complying in good faith, has become insolvent, or has assigned or subcontracted any part of the Work without the Board’s consent. In the event of such cancellation, the Contractor will be paid the actual amount due based on Contract Unit Prices or lump sums bid and the quantity of the Work completed at the time of cancellation, less damages caused to the Agency by acts of the Contractor. The Contractor, in having tendered a Bid, shall be deemed to have waived any and all claims for damages because of cancellation of Contract for any such reason. If the Agency declares the Contract canceled for any of the above reasons, written notice to that effect shall be served upon the Surety. The Surety shall, within five (5) days, assume control and perform the Work as successor to the Contractor.

If the Surety assumes any part of the Work, it shall take the Contractor’s place in all respects for that part and shall be paid by the Agency for all work performed by it in a ccordance with the Contract. If the Surety assumes the entire Contract, all money due the Contractor at the time of its default shall be payable to the Surety as the Work progresses, subject to the terms of the Contract.

If the Surety does not assume control and perform the Work within 5 days after receiving notice of cancellation, or fails to continue to comply, the Agency may exclude the Surety from the prem- ises. The Agency may then take possession of all material and equipment and complete the Work by Agency forces, by letting the unfinished Work to another Contractor, or by a combinati on of such methods. In any event, the cost of completing the Work shall be charged against the Con- tractor and its Surety and may be deducted from any money due or becoming due from the Agency. If the sums due under the Contract are insufficient for complet ion, the Contractor or Surety shall pay to the Agency within 5 days after the completion, all costs in excess of the sums due.

The provisions of this section shall be in addition to all other rights and remedies available to the Agency under law.

6-5 TERMINATION OF CONTRACT. The Board may terminate the Contract at its own dis- cretion or when conditions encountered during the Work make it impossible or impracticable to proceed, or when the Agency is prevented from proceeding with the Contract by act of God, by law, or by official action of a public authority.

Revised 6/15/17 Contract No. 5503-21 Page 92 of 122
6-6 DELAYS AND EXTENSIONS OF TIME.

6-6.1 General. If delays are caused by unforeseen events beyond the control of the Contractor, such delays will entitle the Contractor to an extension of time as provided herein, but the Contrac- tor will not be entitled to damages or additional payment due to such delays, except as provided in 6 -6.3. Such unforeseen events may include: war, government regulations, labor disputes, strikes, fires, floods, adverse weather or elements necessitating cessation of work, inability to obtain materials, labor or equipment, required extra work, or other specific events as may be further described in the Specifications.

If delays beyond the Contractor’s control are caused by events other than those mentioned above, the Engineer may deem an extension of time to be in the best interests of the Agency. The Con- tractor will not be entitled to damages or additional payment due to such delays, except as pro- vided in Section 6-6.3.

If delays beyond the Contractor’s control are caused solely by action or inaction by the Agency, such delays will entitle the Contractor to an extension of time as provided in Section 6-6.2.

6-6.2 Extensions of Time. Extensions of time, when granted, will be based upon the effect of delays to the Work. They will not be granted for noncontrolling delays to minor po rtions of the Work unless it can be shown that such delays did or will delay the progress of the Work.

6-6.3 Payment for Delays to Contractor. The Contractor will be compensated for damages incurred due to delays for which the Agency is responsible. Such actual costs will be determined by the Engineer. The Agency will not be liable for da mages which the Contractor could have avoided by any reasonable means, such as judicious handling of forces, equipment, or plant. The determination of what damages the Contractor could have avoided will be made by the Engineer.

6-6.4 Written Notice and Report. The Contractor shall provide written notice to the Engineer within two hours of the beginning of any period that the Contractor has placed any workers or equipment on standby for any reason that the Contractor has determined to be caused by the Agency or by any organization that the Agency may otherwise be obligated by.

The Contractor shall incorporate the dates, areas and types of work prohibited in this section in the Construction Schedule required by Section 6.1. No additional payment, adjustment of bid prices or adjustment of contract time of completion will be allowed as a consequence of the pro- hibition of work being performed within the dates, areas and/or types of work prohibited in this section.

6-7.3 Contract Time Accounting. The Engineer will make a daily determination of each work- ing day to be charged against the Contract time. These determinations will be discussed and the Contractor will be furnished a periodic statement showing allowable number of working days of Contract time, as adjusted, at the beginning of the reporting period. The statement will also indi- cate the number of working days charged during the reporting period and the number of working days of Contract time remaining. If the Contractor does not agree with the statement, it shall file a written protest within 15 days after receipt, setting forth the facts of the protest. Otherwise, the statement will be deemed to have been accepted.

6-8 COMPLETION, ACCEPTANCE, AND WARRANTY. The Work will be inspected by the Engineer for acceptance upon receipt of the Contractor’s written assertion that the Work has been completed.

The Engineer will not accept the Work or any portion of the Work before all of the Work is com- pleted and all outstanding deficiencies that may exist are corrected by the Contractor and the Engineer is satisfied that all the materials and workmanship, and all other features of the Work, meet the requirements of all of the specifications for the Work. Use, temporary, interim or perma- nent, of all, or portions of, the Work does not constitute acceptance of the Work. If, in the Engi- neer’s judgment, the Work has been completed and is ready for acceptance the Engineer will so certify to the Board. Upon such certification by the Engineer the Board may accept the completed Work. Upon the Board’s acceptance of the Work the Engineer will cause a “Notice of Completion” to be filed in the office of the San Dieg o County Recorder. The date of recordation shall be the date of completion of the Work.

All work shall be warranted for one (1) year after recordation of the "Notice of Completion" and any faulty work or materials discovered during the warranty period shall be repaired or replaced by the Contractor, at its expense. Twenty-five percent of the faithful performance bond shall be retained as a warranty bond for the one year warranty period. The Contractor shall replace or repair any such defective work in a manner satisfactory to the Engineer, after notice to do so from the Engineer, and within the time specified in the notice.

4. Any liner that does not meet the specified strength and/or thickness requirements, regardless of the amount below the specified requirements, shall be corrected by the CONTRACTOR in a manner approved by the ENGINEER at no additional cost to the AGENCY. The ENGINEER’s decision on how to correct deficient CIPP installations shall be final.

Options for correcting deficient liners that may be considered by the ENGINEER include removing the liner and re-lining the sewer, or excavating and replacing the sewer from manhole to manhole, or providing the AGENCY with a credit. The primary option that will be considered will be to re-line the sewer. Credits will only be authorized for CIPP that does not meet required thickness. If a credit is acceptable to the AGENCY, the credit shall be calculated by multiplying the bid price by the percent that the liner thickness is below the required installed thickness as follows: Credit = (1- Installed CIPP Thickness/Required CIPP Thickness) x Bid Price.
