ACCEPTABILITY OF INSURERS
Insurance is to be placed with insurers authorized to conduct business in the state with a current Best rating of no less than A: VII, unless otherwise acceptable to the City of Vallejo.

WAIVER OF SUBROGATION
Contractor hereby agrees to waive rights of subrogation which any insurer of Contractor may acquire from Contractor by virtue of the payment of any loss. Contractor agrees to obtain any endorsement that may be necessary to affect this waiver of subrogation. The Workers’ Compensation policy shall be endorsed with a waiver of subrogation in favor of the City of Vallejo for all work performed by the Contractor, its employees, agents and subcontractors.

VERIFICATION OF COVERAGE
Contractor shall furnish the City of Vallejo with original Certificates of Insurance including all required amendatory endorsements (or copies of the applicable policy language effecting coverage required by this clause) and a copy of the Declarations and Endorsement Page of the CGL policy listing all policy endorsements to City of Vallejo before work begins. However, failure to obtain the required documents prior to the work beginning shall not waive the Contractor’s obligation to provide them. The City of Vallejo reserves the right to require complete, certified copies of all required insurance policies, including endorsements, required by these specifications, at any time. Failure to exercise this right shall not constitute a waiver of right to exercise later. All verification of coverage and other insurance documents shall be mailed to the following address:

City of Vallejo
Attn: Risk Manager
555 Santa Clara Street
Vallejo, CA 94590

SUBCONTRACTORS
Contractor shall require and verify that all subcontractors maintain insurance meeting all requirements stated herein, and Contractor shall ensure that City of Vallejo is an additional insured on insurance required from subcontractors. For CGL coverage, subcontractors shall provide coverage with a form at least as broad as CG 20 38 04 13.

City of Vallejo will withhold payments to Contractor if the certificates of insurance and endorsements required in this exhibit are canceled or Contractor otherwise ceases to be insured as required herein. 7-1.12B(4) ENFORCEMENT
The City of Vallejo may take any steps as are necessary to assure Contractor's compliance with its obligations.

Should any insurance policy lapse or be canceled during the Contract period the Contractor shall, within thirty (30) days prior to the effective expiration or cancellation date, furnish the City of Vallejo with evidence of

CITY OF VALLEJO 209 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
renewal or replacement of the policy. Failure to continuously maintain insurance coverage as herein provided is a material breach of Contract. In the event the Contractor fails to maintain any insurance coverage required, the City of Vallejo may, but is not required to, maintain this coverage and charge the expense to the Contractor or terminate Contractor’s control over the work. The required insurance shall be subject to the review and acceptance of City of Vallejo, but any acceptance of insurance certificates by the City of Vallejo shall in no way limit or relieve the Contractor of the Contractor's duties and responsibilities under the Contract to indemnify, defend and hold harmless the City of Vallejo, its officers, agents, and employees. Insurance coverage in the minimum amounts set forth herein shall not be construed to relieve the Contractor for liability in excess of such coverage, nor shall it preclude the City of Vallejo from taking other actions as is available to it under any other provision of the Contract or law. Failure of the City of Vallejo to enforce in a timely manner any of the provisions of this section shall not act as a waiver to enforcement of any of these provisions at a later date. 7-1.12B(5) SELF-INSURANCE
Self-insurance programs and self-insured retentions in insurance policies are subject to separate annual review and acceptance by the City of Vallejo of evidence of the Contractor's financial capacity to respond. Additionally, self-insurance programs or retentions must provide the City of Vallejo with at least the same protection from liability and defense of suits as would be afforded by first-dollar insurance. 7-1.12B(6) MISCELLANEOUS
Nothing contained in the Contract is intended to make the public or any member thereof a third party beneficiary of the Insurance or Indemnity provisions of these Standard Specifications, nor is any term, condition or other provision of the Contract intended to establish a standard of care owed to the public or any member thereof.

CITY OF VALLEJO 210 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
7-1.13 DISPOSAL OF MATERIAL OUTSIDE THE PUBLIC RIGHT OF WAY If the Contractor elects to dispose of materials at locations other than those where arrangements have been made by the City of Vallejo, or, if material is to be disposed of and the City of Vallejo has not made arrangements for disposal of the material, the Contractor shall make arrangements for disposing of the materials outside the public right of way and shall pay all costs involved. Arrangements shall include, but not be limited to, entering into agreements with property owners and obtaining necessary permits, licenses and environmental clearances. Before disposing of any material outside the public right of way, the Contractor shall furnish to the Engineer satisfactory evidence that the Contractor has entered into agreements with the property owners of the site(s) involved and has obtained the appropriate permits, licenses and clearances.

When any material is to be disposed of outside the public right of way, and the City of Vallejo has not made arrangements for disposal of the material, the Contractor shall first obtain written authorization from the property owner on whose property the disposal is to be made and the Contractor shall file with the Engineer the authorization or a certified copy thereof together with a written release from the property owner absolving the City of Vallejo from any and all responsibility in connection with the disposal of material on the property.

Before any material is disposed of on the property, the Contractor shall obtain written permission from the Engineer to dispose of the material at the location designated in the authorization.

When material is disposed of as above provided and the disposal location is visible from public view, the Contractor shall dispose of the material in a neat and uniform manner to the satisfaction of the Engineer.

Where the City of Vallejo has made arrangements with owners of land in the vicinity of a project for the disposal of materials on an owner's property, the arrangements are made solely for the purpose of providing all Bidders an equal opportunity to dispose of the materials on the property. Bidders or Contractors may, upon written request, inspect the documents evidencing the arrangements between property owners and the City of Vallejo.

The Contractor may, if the Contractor so elects, exercise any rights that have been obtained, which may be exercised by a Contractor under the arrangements, subject to and upon the conditions hereinafter set forth.

Such arrangements are not a part of the Contract and it is expressly understood and agreed that the City of Vallejo assumes no responsibility to the Bidder or Contractor whatsoever in respect to the arrangements made with the property owner to dispose of materials thereon and that the Contractor shall assume all risks in connection with the use of the property, the terms upon which the use shall be made, and there is no warranty or guaranty, either express or implied, as to the quantity or types of materials that can be disposed of on the property, or that any material can be disposed of on the property.

In those instances in which the City of Vallejo has compiled "Materials Information" as referred to in Section 2-1.03, "Examination of Plans, Specifications, Contract, and Site of Work," the compilation will include the documents setting forth the arrangement made with some of the property owners for the disposal of material on those owners' properties. The inclusion of the documents therein shall not in any respect operate as a waiver of any of the provisions in this Section 7-1.13 concerning the documents.

The Bidder or Contractor shall make such independent investigation and examination as the Bidder or Contractor deems necessary to be satisfied as to the quantity and types of materials which may be disposed of on the property (if any) and the rights, duties and obligations acquired or undertaken under the arrangement with the property owner.

Notwithstanding that the Contractor may elect to dispose of materials on any such property owner's property, no material may be disposed of on that property unless the Contractor has first either:

A. Executed a document that will guarantee to hold the owner harmless from all claims for injury to persons or damage to property resulting from the Contractor's operations on the property owner's premises and also agree to conform to all other provisions set forth in the arrangement made between the City of Vallejo and the property owner, or

CITY OF VALLEJO 211 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
B. Entered into an agreement with the owner of the disposal site on any terms mutually agreeable to the owner and the Contractor; provided that the Contractor shall furnish to the Engineer a release, in a form satisfactory to the Engineer, executed by the owner, relieving the City of Vallejo of any and all obligations under the City of Vallejo's arrangement with the owner.

If the Contractor elects to dispose of material under (1), the use of the site shall be subject to the terms, conditions and limitations of the arrangement made between the property owner and the City of Vallejo and the Contractor shall pay those charges that are provided for in the arrangement made by the City of Vallejo with the property owner, and deductions will be made from any moneys due or that may become due the Contractor under the Contract sufficient to cover the charges for the material disposed of.

If the Contractor elects to dispose of material under (2), the Contractor shall pay those charges that are provided for in the agreement between the owner and the Contractor and deductions will not be made from any moneys due or that may become due the Contractor under the Contract to cover the charges.

Before acceptance of the Contract, the Engineer may require the Contractor to submit written evidence that the owner of the disposal site is satisfied that the Contractor has satisfactorily complied with the provisions of either - (1), the arrangement between the City of Vallejo and the owner, or (2), the agreement between the owner and the Contractor, as the case may be.

Full compensation for all costs involved in disposing of materials as specified in this Section 7-1.13, including all costs of hauling, shall be considered as included in the price paid for the Contract item of work involving the materials and no additional compensation will be allowed therefor. 7-1.14 COOPERATION
Should construction be under way by other forces or by other Contractors within or adjacent to the limits of the work specified or should work of any other nature be under way by other forces within or adjacent to those limits, the Contractor shall cooperate with all the other Contractors or other forces to the end that any delay or hindrance to their work will be avoided. The City reserves the right to perform, or to have performed, other or additional work at or near the site (including material sources) at any time, by the use of other forces, without changing the character of the work.

When 2 or more Contractors are employed on related or adjacent work, or obtain materials from the same material source, as provided in Section 6-2.02, "Possible Local Material Sources," or Section 6-2.03, "Mandatory Local Material Sources," each shall conduct their operations in such a manner as not to cause any unnecessary delay or hindrance to the other.

Each Contractor shall be responsible to the other for all damage to work, to persons or property caused to the other by their operations, and for loss caused the other due to unnecessary delays or failure to finish the work within the time specified for completion.
7-1.15 RELIEF FROM MAINTENANCE AND RESPONSIBILITY
Upon request of the Contractor, the Director, or the Director’s designated representative, may relieve the Contractor of the duty of maintaining and protecting certain portions of the work as described below, which have been completed in all respects in accordance with the requirements of the Contract and to the satisfaction of the Engineer, and thereafter except with the Contractor's consent, the Contractor will not be required to do further work thereon. In addition, the action by the Director will relieve the Contractor of responsibility for injury or damage to those completed portions of the work resulting from use by public traffic or from the action of the elements or from any other cause but not from injury or damage resulting from the Contractor's own operations or from the Contractor's negligence.

CITY OF VALLEJO 212 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
However, nothing in this Section 7-1.15 providing for relief from maintenance and responsibility will be construed as relieving the Contractor of full responsibility for making good any defective work or materials found at any time before the formal written acceptance of the entire Contract by the Director. Furthermore, nothing in this section shall obligate the Director to relieve the Contractor for responsibility for any portion of the work and the Director may refuse to relieve the Contractor from responsibility for any reason, at the Director’s (or his delegee’s) sole discretion.
7-1.16 CONTRACTOR'S RESPONSIBILITY FOR THE WORK AND MATERIALS The Contractor shall be completely responsible for the care and condition of the project improvements in their entirety until completion of the maintenance period and acceptance by the City. The Contractor shall provide all watchmen, guards, and security devices, as he/she deems necessary.

Until the acceptance of the Contract, the Contractor shall have the charge and care of the work and of the materials to be used therein (including materials for which the Contractor has received partial payment as provided in Section 9-1.06, "Partial Payments," or materials which have been furnished by the City of Vallejo) and shall bear the risk of injury, loss or damage to any part thereof by the action of the elements or from any other cause, whether arising from the execution or from the non-execution of the work, except as provided in Sections 7-1.08, "Public Convenience," and 7-1.15, "Relief From Maintenance and Responsibility." The Contractor shall rebuild, repair, restore, and make good all injuries, losses or damages to any portion of the work or the materials occasioned by any cause before its completion and acceptance and shall bear the expense thereof, except as otherwise expressly provided in Section 7-1.165, "Damage by Storm, Flood, Tsunami or Earthquake," and in Section 19-2.04, "Slides and Slipouts," and except for those injuries, losses, or damages that are directly and proximately caused by acts of the Federal Government or the public enemy.

Where necessary to protect the work or materials from damage, the Contractor shall, at the Contractor's expense, provide suitable drainage of the roadway and erect those temporary structures that are necessary to protect the work or materials from damage. The suspension of the work from any cause whatever shall not relieve the Contractor of the responsibility for the work and materials as herein specified. If ordered by the Engineer, the Contractor shall, at the Contractor's expense, properly store materials which have been partially paid for by the City of Vallejo or which have been furnished by the City of Vallejo. Storage by the Contractor shall be on behalf of the City of Vallejo and the City of Vallejo shall at all times be entitled to the possession of the materials, and the Contractor shall promptly return the materials to the site of the work when requested.

The Contractor shall not dispose of any of the materials so stored except on written authorization from the Engineer.
7-1.165 DAMAGE BY STORM, FLOOD, TSUNAMI OR EARTHQUAKE
Attention is directed to Section 7-1.16, "Contractor's Responsibility for the Work and Materials." In the event damage to the work is caused by a storm, flood, tsunami, earthquake or other natural disaster which constitutes an "Occurrence," as hereinafter defined, the provisions in this Section 7-1.165 shall be applicable, and the Contractor may apply in writing to the Engineer for the City of Vallejo to pay or participate in the cost of repairing damage to the work from that cause or, in lieu thereof, and at the sole discretion of the City of Vallejo, terminate the Contract and relieve the Contractor of further obligation to perform the work, subject to the following:

A. Occurrence - "Occurrence" shall include tsunamis, earthquakes in excess of a magnitude of 3.5 on the Richter Scale, and storms, floods and other natural disasters as to which the Governor has proclaimed a state of emergency when the damaged work is located within the territorial limits to which the proclamation is applicable or, which were, in the opinion of the Engineer, of a magnitude at the site of the work sufficient to have caused such a proclamation had they occurred in a populated area or in an area in which such a proclamation was not already in effect.

B. Application by Contractor - The Contractor's written request for the City of Vallejo to pay or to participate in the cost of rebuilding, repairing, restoring or otherwise remedying the damage to the work

caused by the Occurrence shall be submitted to the Engineer before performing any work other than emergency work, including emergency work necessary to provide for passage of public traffic.

C. Protecting the Work from Damage - Nothing in this section shall be construed to relieve the Contractor of the responsibility to protect the work from damage. The Contractor shall bear the entire cost of repairing damage to the work caused by the Occurrence which the Engineer determines was due to the failure of the Contractor to comply with the requirements of the Contract Documents, take the best measures to protect the work or exercise the best engineering and construction practices in the conduct of the work, and those repair costs shall be excluded from consideration under the provisions of this section.

D. Repair Work - Repair of damaged work under the provisions of this section shall be pursuant to a Contract Change Order issued hereunder and specifying the repair work to be performed on the damaged facility. The repair work shall consist of restoring the in-place construction (for the purposes of this section erected falsework and formwork shall be considered in-place construction) to the same state of completion to which the work had advanced prior to the Occurrence. Emergency work which the Engineer determines would have been part of the repair work if it had not previously been performed, will be considered to be part of the repair work.

The City of Vallejo reserves the right to make changes in the drawings and Specifications applicable to the portions of the work to be repaired, and if those changes will increase the cost of repairing the damage over the Engineer's estimate of the cost of repair without the changes, the Contractor will be paid for the increased costs in accordance with Subsection E and the increased cost amount shall not be considered in determining the cost of repair to be borne by the Contractor under Subsection F.

Nothing in this section shall be construed to relieve the Contractor of full responsibility for the risk of injury, loss or damage to materials not yet incorporated in the work and to materials, tools and equipment (except erected falsework and formwork) used to perform the work, or to relieve the Contractor of responsibility under Section 7-1.12, "Indemnification and Insurance." The provisions of this section shall not be applicable to the repair of damage caused by an Occurrence to any portion of the work as to which the Contractor has been granted relief from maintenance and responsibility pursuant to Section 7-1.15, "Relief From Maintenance and Responsibility," or to the removal of slides and slipouts or the repair and restoration of damage to the work resulting from slides and slipouts pursuant to Section 19-2.04, "Slides and Slipouts." E. Determination of Costs - Unless otherwise agreed between the Engineer and the Contractor, the cost of the work performed pursuant to this Section 7-1.165 will be determined in conformance with the provisions in Section 9-1.03, "Force Account Payment," except there shall be no markup allowance pursuant to Section 9-1.03A, "Work Performed by Contractor," unless the Occurrence that caused the damage was a tsunami or earthquake. The cost of emergency work, which the Engineer determines would have been part of the repair work if it had not previously been performed, will be determined in the same manner as the authorized repair work. The cost of repairing damaged work which was not in compliance with the requirements of the drawings and Specifications shall be borne solely by the Contractor, and those costs shall not be considered in determining the cost of repair under this Subsection E.

F. Payment for Repair Work - BLANK
G. Termination of Contract - If the City of Vallejo elects to terminate the Contract, the termination and the determination of the total compensation payable to the Contractor shall be governed by the provisions of Section 8-1.11, "Termination of Contract."
7-1.17 ACCEPTANCE OF CONTRACT

Upon satisfactory completion of the Work and following the written acceptance of the Work as such by the Director or the Director’s designated representative, the Engineer shall recommend the acceptance of the Contract to the City Council. Upon acceptance of the Contract as complete by the City Council, the said Council shall cause a Notice of Completion to be filed and recorded in the records of the Solano County Recorder's Office. 7-1.18 PROPERTY RIGHTS IN MATERIALS
Nothing in the Contract shall be construed as vesting in the Contractor any right of property in the materials used after they have been attached or affixed to the work or soil or after partial payment has been made as provided in Section 9-1.06, "Partial Payments," for material delivered on the ground or stored subject to or under the control of the City of Vallejo and unused. All the material shall become the property of the City of Vallejo upon being so attached or affixed or upon payment for materials delivered on the ground or stored subject to or under the control of the City of Vallejo and unused, as provided in Section 9-1.06. 7-1.19 RIGHTS IN LAND AND IMPROVEMENTS
Nothing in these Contract Documents shall be construed as allowing the Contractor to make any arrangements with any person to permit occupancy or use of any land, structure, or building within the limits of the Contract for any purpose whatsoever, either with or without compensation, in conflict with any agreement between the City of Vallejo and any owner, former owner, or tenant of the land, structure, or building.

The Contractor shall not occupy City of Vallejo-owned property outside the right of way as shown on the drawings or maps, unless the Contractor enters into a rental agreement with the City of Vallejo. The agreement will be based on fair rental values.
7-1.20 PERSONAL LIABILITY
Neither the Director, the Engineer nor any other officer or authorized employee of the City of Vallejo, nor any officer or employee of any county, city or district shall be personally responsible for any liability arising under or by virtue of the Contract.

SECTION 8: PROSECUTION AND PROGRESS
8-1.01 SUBCONTRACTING
The Contractor shall give personal attention to the fulfillment of the Contract and shall keep the work under the Contractor's control.

No subcontractor will be recognized as such, and all persons engaged in the work of construction will be considered as employees of the Contractor and the Contractor will be held responsible for their work, which shall be subject to the provisions of the Contract Documents.

The Contractor shall perform, with the Contractor's own organization, Contract work amounting to not less than 50 percent of the original total Contract price, except that any designated "Specialty Items" may be performed by subcontract and the amount of any designated "Specialty Items" performed by subcontract may be deducted from the original total Contract price before computing the amount of work required to be performed by the Contractor with the Contractor's own organization. When items of work in the Engineer's Estimate are preceded by the letters (S) or (S-F), those items are designated as "Specialty Items." Where an entire item is subcontracted, the value of work subcontracted will be based on the Contract item bid price. When a portion of an item is subcontracted, the value of work subcontracted will be based on the estimated percentage of the Contract item bid price, determined from information submitted by the Contractor, subject to acceptance by the Engineer.

Subcontracts shall include provisions that the Contract between the City of Vallejo and the Contractor is part of the subcontract, and that all terms and provisions of the Contract are incorporated in the subcontract.

Subcontracts shall also contain certification by the subcontractor that the subcontractor is experienced in and qualified to do, and knowledgeable about, the subcontracted work. Copies of subcontracts shall be available to the Engineer upon written request, and shall be provided to the Engineer within three (3) days of the Engineer’s request.

Pursuant to the provisions of Section 6109 of the Public Contract Code, the Contractor shall not perform work on a public works project with a subcontractor who is ineligible to perform work on the public works project pursuant to Section 1777.1 or 1777.7 of the Labor Code.

When a portion of the work which has been subcontracted by the Contractor is not being prosecuted in a manner satisfactory to the City of Vallejo, the subcontractor shall be removed immediately on the request of the Engineer and shall not again be employed on the work.

The roadside production of materials produced by other than the Contractor's forces shall be considered as subcontracted. Roadside production of materials shall be construed to be production of aggregates of all kinds with portable, semi portable or temporary crushing or screening, proportioning and mixing plants established or reopened for the purpose of supplying aggregate or material for a particular project or projects. The erection, establishment or reopening of the plants and the operation thereof in the production of materials for use on the work shall conform to the requirements relating to labor set forth in these Specifications and in the special provisions.

When any portion of the work which has been subcontracted by the Contractor is not being prosecuted in a satisfactory manner, the subcontract for such work shall be terminated immediately by the Contractor upon written notice from the Engineer, and the subcontractor shall not again be employed on the type of work in which his or her performance was unsatisfactory.

In no case shall the use of subcontractors in any way alter the position of the Contractor or Contractor's sureties with relation to this Contract. When a subcontractor is used, the responsibility for every portion of the work shall still remain with the Contractor.

CITY OF VALLEJO 216 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
The Contractor shall pay, when due, all valid claims of subcontractors, suppliers, and workmen with respect to the project.

The mention herein of any specific duty or responsibility imposed upon the Contractor shall not be construed as a limitation or restriction of any other responsibility or duty imposed upon the Contractor by the Contract, said reference being made herein merely for the purpose of explaining the specific duty or responsibility. 8-1.02 ASSIGNMENT
The performance of the Contract may not be assigned, except upon the written consent of the Director.

Consent will not be given to any proposed assignment which would relieve the original Contractor or the Contractor's surety of their responsibilities under the Contract nor will the Director consent to any assignment of a part of the work under the Contract.

The Contractor may assign moneys due or to become due the Contractor under the Contract and the assignment will be recognized by the City of Vallejo, if given proper notice thereof, to the extent permitted by law, but any assignment of moneys shall be subject to all proper set-offs in favor of the City of Vallejo and to all deductions provided for in the Contract and particularly all money withheld, whether assigned or not, shall be subject and subordinate to claims of the City of Vallejo. 8-1.03 BEGINNING OF WORK
The Contractor shall begin work within 10 calendar days after the first working day stated on the Notice to Proceed and shall diligently prosecute the same to completion within the time limit provided in the Notice to Contractors.

The Contractor shall notify the Engineer, in writing, of the Contractor's intent to begin work at least 72 hours before work is begun. The notice shall be delivered to the Engineer and shall specify the date the Contractor intends to start. If the project has more than one location of work, a separate notice shall be given for each location.

Should the Contractor begin work in advance of receiving written Notice to Proceed, any work performed by the Contractor in advance of the date of Notice to Proceed shall be considered as having been done by the Contractor at the Contractor's own risk and as a volunteer.

The Notice to Proceed shall constitute authority for the Contractor to enter upon the site of the work and to begin operations, upon condition that the Contractor has strictly complied with all requirements of these Contract Documents, including but not limited to, furnishing all required documentation and certificates of insurance. If Contractor has not provided City of Vallejo with all documents required by these Contract Documents as of the date of the Notice to Proceed, Contractor shall not be allowed on the site of the work or allowed to start work on the Project, notwithstanding the issuance of a Notice to Proceed.

When the Contractor has started work on the Project, the Contractor shall diligently prosecute the work to completion within the time limit provided in the Contract Documents.

The counting of working days shall begin on the date stated as the first working day on the Notice to Proceed, whether or not Contractor is allowed on the work site due to Contractor's failure to furnish City of Vallejo with all documentation required by these Contract Documents. In no event shall there be a period of time greater than thirty (30) days, from the time the Contract forms are first received by the Contractor and the commencement of the contract time, regardless of the receipt or lack thereof by City of Vallejo of all documents required by these Contract Documents. The Contractor shall, on commencing operations, take all precautions required for public safety and shall observe all the provisions in these Specifications and the special provisions.

The Maintenance Inspector shall be present before, during, and after the tie-in is completed, to ensure that the trench is completely back filled before the water is turned on. If the Contractor fails to coordinate the tie-in with the Maintenance Inspector, the said tie-in will not be accepted.

B. If the Contractor schedules a tie-in with the Maintenance Inspector and is not ready for the tiein on the scheduled date, the contractor will be charged for the Maintenance Inspector's time, unless the Contractor cancels the inspection 24 hours in advance.

7. As-Built Drawings
The Contractor shall always keep an up to date complete and accurate set of record prints, which shall be corrected regularly, showing every change from the Contract Documents, including all addendums, Change Orders, RFIs, etc. Upon completion of the work, a set of as-built prints shall be made by the Contractor after consultation with the Engineer and all changes noted. All changes shall be neatly and legibly drawn to scale on the set of prints using standard architectural or engineering drafting practices.

8. Hazardous Waste in Excavation
If the Contractor encounters material which the contractor has reason to believe may be hazardous waste as defined by Section 25117 of the Health and Safety Code, the contractor shall immediately so notify the Engineer in writing. All work in the immediate area of the suspected hazardous material shall be suspended until the Engineer authorizes it to be resumed. If such suspension delays the current controlling work by more than one (1) working day, the Contractor shall be granted an extension of time as provided in Section 8-1.07, “Liquidated Damages,” of the General Provisions.

The City reserves the right to use other forces for exploratory work to identify and determine the extent of hazardous material and for removing such material.

9. Changed Conditions
a. Differing Site Conditions
The requirements specified in Section 4-1.06 of the State Standard Specifications for differing site conditions apply to this project.
b. Suspensions of Work Ordered by the Engineer
If the performance of all or any portion of the work is suspended or delayed by the engineer in writing for an unreasonable period of time (not originally anticipated, customary, or inherent to the construction industry) and the contractor believes that additional compensation and/or contract time is due as a result of such suspension or delay, the contractor shall submit to the engineer in writing a request for adjustment within 7 calendar days of receipt of the notice to resume work. The request shall set forth the reasons and support for such adjustment.

Upon receipt, the engineer will evaluate the contractor's request. If the engineer agrees that the cost and/or time required for the performance of the contract has increased as a result of such suspension and the suspension was caused by conditions beyond the control of and not the fault of the contractor, its suppliers, or subcontractors at any approved tier, and not caused by weather, the engineer will make an adjustment (excluding profit) and modify the contract in writing accordingly. The contractor will be notified of the engineer's determination whether an adjustment of the contract is warranted.

CITY OF VALLEJO 219 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
No contract adjustment will be allowed unless the contractor has submitted the request for adjustment within the time prescribed.

No contract adjustment will be allowed under this clause to the extent that performance would have been suspended or delayed by any other cause, or for which an adjustment is provided or excluded under any other term or condition of this contract.
c. Significant Changes in the Character of Work
The engineer reserves the right to make, in writing, at any time during the work, such changes in quantities and such alterations in the work as are necessary to satisfactorily complete the project. Such changes in quantities and alterations shall not invalidate the contract nor release the surety, and the contractor agrees to perform the work as altered.

If the alterations or changes in quantities significantly change the character of the work under the contract, whether such alterations or changes are in themselves significant changes to the character of the work or by affecting other work cause such other work to become significantly different in character, an adjustment, excluding anticipated profit, will be made to the contract. The basis for the adjustment shall be agreed upon prior to the performance of the work. If a basis cannot be agreed upon, then an adjustment will be made either for or against the contractor in such amount as the engineer may determine to be fair and equitable.

If the alterations or changes in quantities do not significantly change the character of the work to be performed under the contract, the altered work will be paid for as provided elsewhere in the contract.

The term “significant change” shall be construed to apply only to the following circumstances:
 When the character of the work as altered differs materially in kind or nature from that involved or included in the original proposed construction; or
 When a major item of work, as defined elsewhere in the contract, is increased more than 125 percent, or decreased below 75 percent of the original contract quantity. Any allowance for an increase in quantity shall apply only to that portion more than 125 percent of the original contract item quantity, or in case of a decrease below 75 percent, to the actual amount of work performed. 8-1.05 TEMPORARY SUSPENSION OF WORK
The Engineer shall have the authority to suspend the work wholly or in part, for any time period as the Engineer deems necessary, due to unsuitable weather, or to such other conditions considered unfavorable for the suitable prosecution of the work, or for any time period as the Engineer deems necessary due to the failure on the part of the Contractor to carry out orders given, or to perform any provision of the Contract, or for any other reason. The Contractor shall immediately comply with the written order of the Engineer to suspend the work wholly or in part. The suspended work shall be resumed when conditions are favorable and methods are corrected, as ordered or accepted in writing by the Engineer, or as directed by the Engineer.

In the event that a suspension of work is ordered as provided above, and should that suspension be ordered by reason of the failure of the Contractor to carry out orders or to perform any provision of the Contract; or by reason of weather conditions being unsuitable for performing any item or items of work, which work, in the sole opinion of the Engineer, could have been performed prior to the occurrence of the unsuitable weather conditions had the Contractor diligently prosecuted the work when weather conditions were suitable; the Contractor, at the Contractor's expense, shall do all the work necessary to provide a safe, smooth, and unobstructed passageway through construction for use by public traffic during the period of that suspension as provided in Sections 7-1.08, "Public Convenience," and 7-1.09, "Public Safety," and as specified in the special provisions for the work. In the event that the Contractor fails to perform the work above specified, the City of Vallejo will perform that work and the cost thereof will be deducted from moneys due or to become due the Contractor.

CITY OF VALLEJO 220 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
In the event that a suspension of work is ordered by the Engineer due to unsuitable weather conditions, and in the sole opinion of the Engineer, the Contractor has prosecuted the work with energy and diligence prior to the time that operations were suspended, the cost of providing a smooth and unobstructed passageway through the work will be paid for as extra work as provided in Section 4-1.03D or, at the option of the Engineer, that work will be performed by the City of Vallejo at no cost to the Contractor.

If the Engineer orders a suspension of all of the work or a portion of the work which is the current controlling operation or operations, due to unsuitable weather or to other conditions considered unfavorable to the suitable prosecution of the work, the days on which the suspension is in effect shall not be considered working days as defined in Section 8-1.06, "Time of Completion." If a portion of work at the time of the suspension is not a current controlling operation or operations, but subsequently does become the current controlling operation or operations, the determination of working days will be made on the basis of the current controlling operation or operations.

If a suspension of work is ordered by the Engineer, due to the failure on the part of the Contractor to carry out orders given or to perform any provision of the Contract, the days on which the suspension order is in effect shall be considered working days if those days are working days within the meaning of the definition set forth in Section 8-1.06, "Time of Completion."
No Contract adjustment will be allowed under the provisions specified in this section to the extent that performance would have been suspended or delayed by any other cause, or for which an adjustment is provided for or excluded under any term or condition of this Contract.

Any Contract adjustment warranted due to suspension of work ordered by the Engineer will be made in the same manner as provided for right of way delays in Section 8-1.09, "Right of Way Delays." In the event of a suspension of work under any of the conditions set forth in this Section 8-1.05, the suspension of work shall not relieve the Contractor of the responsibilities as set forth in Section 7, "Legal Relations and Responsibility."
8-1.06 TIME OF COMPLETION
The Contractor shall complete all or any designated portion of the work called for under the Contract Documents in all parts and requirements within the time set forth in the Contract Documents.

A working day is defined as any day, except as follows:

A. Saturdays, Sundays and legal holidays;
B. Days on which the Contractor is prevented by inclement weather or conditions resulting immediately therefrom adverse to the current controlling operation or operations, as determined by the Engineer, from proceeding with at least 75 percent of the normal labor and equipment force engaged on that operation or operations for at least 60 percent of the total daily time being currently spent on the controlling operation or operations; or
C. Days on which the Contractor is prevented, by reason of requirements in "Maintaining Traffic" of the special provisions, from working on the controlling operation or operations for at least 60 percent of the total daily time being currently spent on the controlling operation or operations.

Should the Contractor prepare to begin work at the regular starting time of any day on which inclement weather, or the conditions resulting from the weather, or the condition of the work, prevents the work from beginning at the usual starting time and the crew is dismissed as a result thereof and the Contractor does not proceed with at least 75 percent of the normal labor and equipment force engaged in the current

CITY OF VALLEJO 221 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
controlling operation or operations for at least 60 percent of the total daily time being currently spent on the controlling operation or operations, the Contractor will not be charged for a working day whether or not conditions should change thereafter during that day and the major portion of the day could be considered to be suitable for those construction operations.

The current controlling operation or operations is to be construed to include any feature of the work (e.g., an operation or activity, or a settlement or curing period) considered at the time by the Engineer and the Contractor, which, if delayed or prolonged, will delay the time of completion of the Contract.

Determination that a day is a non-working day by reason of inclement weather or conditions resulting immediately therefrom, shall be made by the Engineer. The Contractor will be allowed 15 days from the issuance of the weekly statement of working days in which to file a written protest setting forth in what respects the Contractor differs from the Engineer; otherwise, the decision of the Engineer shall be deemed to have been accepted by the Contractor as correct. The Engineer will furnish the Contractor a weekly statement showing the number of working days charged to the Contract for the preceding week, the number of working days of time extensions being considered or accepted, the number of working days originally specified for the completion of the Contract and the number of working days remaining to complete the Contract and the extended date for completion thereof, except when working days are not being charged in conformance with the provisions in Section 8-1.05, "Temporary Suspension of Work." 8-1.07 LIQUIDATED DAMAGES
It is agreed by the parties to the Contract that in case all the work called for under the Contract in all parts and requirements is not completed within the number of working days as set forth in the Contract Documents, damage will be sustained by the City of Vallejo, and that it is and will be impracticable and extremely difficult to ascertain and determine the actual damage which the City of Vallejo will sustain in the event of and by reason of the delay; and it is therefore agreed that the Contractor will pay to the City of Vallejo, the sum set forth in the Contract Documents per day for each and every calendar day's delay in completing the work in excess of the number of working days prescribed; and the Contractor agrees to pay the liquidated damages herein provided for, and further agrees that the City of Vallejo may deduct the amount thereof from any moneys due or that may become due the Contractor under the Contract.

The Contractor will be granted an extension of time and will not be assessed with liquidated damages or the cost of engineering and inspection for any portion of the delay in completion of the work beyond the time named in the Contract Documents for the completion of the work caused by acts of God or of the public enemy, fire, floods, tsunamis, earthquakes, epidemics, quarantine restrictions, strikes, labor disputes, shortage of materials and freight embargoes, provided that the Contractor shall notify the Engineer in writing of the causes of delay within 3 days from the beginning of that delay. The Engineer shall ascertain the facts and the extent of the delay, and the Engineer's findings thereon shall be final and conclusive.

No extension of time will be granted for a delay caused by a shortage of materials unless the Contractor furnishes to the Engineer documentary proof that the Contractor has made every effort to obtain the materials from all known sources in a diligent and timely manner, and further proof in the form of supplementary progress schedules, as required in Section 8-1.04, "Progress Schedule," that the inability to obtain the materials when originally planned, did in fact cause a delay in final completion of the entire work which could not be compensated for by revising the sequence of the Contractor's operations. The term "shortage of materials," as used in this section, shall apply only to materials, articles, parts or equipment which are standard items and are to be incorporated in the work. The term "shortage of materials," shall not apply to materials, parts, articles or equipment which are processed, made, constructed, fabricated or manufactured to meet the specific requirements of the Contract. Only the physical shortage of material will be considered under these provisions as a cause for extension of time. Delays in obtaining materials due to priority in filling orders will not constitute a shortage of materials.

CITY OF VALLEJO 222 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
Except for the additional compensation provided for in Section 8-1.09, "Right of Way Delays," the Contractor shall have no claim for damage or compensation for any delay or hindrance.

It is the intention of the above provisions that the Contractor shall not be relieved of liability for liquidated damages or engineering and inspection charges for any period of delay in completion of the work in excess of that expressly provided for in this Section
8-1.08 TERMINATION OF CONTROL
Whenever, in the opinion of the City of Vallejo, the Contractor has failed to supply an adequate force of labor, equipment, or materials of proper quality, or has failed in any other respect to prosecute the work with the diligence specified in the Contract; or if Contractor should refuse or fail to comply with laws, ordinances, or directions of the Engineer; or if Contractor should fail to make prompt payments to subcontractors or for labor or materials; or otherwise be in breach of this Contract; the City of Vallejo may give written notice of at least five (5) calendar days to the Contractor and Contractor's sureties that if the defaults are not remedied within a time specified in such notice, the Contractor's control over the work will be terminated.

If the Contractor should be adjudged a bankrupt, or make an assignment for the benefit of Contractor's creditors, or if a receiver should be appointed on account of Contractor's insolvency, the City of Vallejo may declare the Contractor's control over the work terminated, and so notify the Contractor and Contractor's sureties.

Upon such termination, the City of Vallejo may take possession, and use all or any part, of the Contractor's materials, tools, equipment, and appliances upon the premises to complete the work; the City of Vallejo assuming responsibility for the final relinquishment of such equipment at the conclusion of the work, or sooner, at its option, in as good condition as when it was taken over, reasonable wear and tear excepted; and the City of Vallejo agrees to pay for such materials and the use of said equipment at a reasonable compensation.

Upon such termination or the City of Vallejo's declaration that the Contractor is in default, the City of Vallejo may direct the surety to complete, or cause to be completed, the Contract work, or the City of Vallejo may direct that all or any part of the work be completed by day labor, or by employment of other contractors on informal contracts, or both. If the City of Vallejo directs the surety to complete or cause to be completed, the Contract work, Contractor's performance bond surety agrees to immediately undertake to complete or cause to be completed, all Contract work. If surety fails or refuses to immediately complete or cause to be completed, all Contract work, surety agrees that damage will be sustained by the City of Vallejo, and that it is and will be impracticable to determine the actual amount of damage by reason of such acts; and the Contractor and surety agree that in addition to any other damages City of Vallejo may sustain and may be recovered pursuant to these Contract Documents, including but not limited to, other liquidated damages for delay, or actual damages, the sum of FIVE HUNDRED DOLLARS ($500.00) is a reasonable amount to be charged as liquidated damages for each day surety fails or refuses to complete or cause to be completed, all Contract work, and it is therefore agreed that the Contractor and surety will pay to the City of Vallejo this sum, for each and every calendar day surety fails or refuses to complete or cause to be completed, the Contract work; and the Contractor and surety further agree that the City of Vallejo may deduct and retain the amount thereof from any monies due the Contractor under the Contract.

If the Contractor's control over the work is terminated as provided above, the Contractor is not entitled to receive any portion of the amount to be paid under the Contract until it is fully completed. After completion, if the unpaid balance exceeds the sum of the amount expended by the City of Vallejo in finishing the work, plus all damages sustained, or to be sustained, by the City of Vallejo, plus any unpaid claims on account of labor, materials, tools, equipment, or supplies contracted for by the Contractor for the work herein contemplated, the excess not otherwise required by these Contract Documents to be retained shall be paid the Contractor. If the sum so expended exceeds the unpaid balance, the Contractor and Contractor's surety

CITY OF VALLEJO 223 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
are liable to the City of Vallejo for the amount of such excess. If the surety completes the Contract work as provided above, such surety shall be subrogated to money due under the Contract, and to money which shall become due in the course of completion by the surety. However, Contractor and surety agree that any subrogation rights of surety are subordinate to and inferior to rights of City of Vallejo.

The City of Vallejo reserves the right to terminate the work for its convenience upon written notice to Contractor. In such event, the Contractor shall be paid its reasonable costs for that portion of the work performed to the date of termination, reasonable costs associated with demobilization, plus fifteen percent (15%) of all such costs for overhead and profit.
8-1.09 RIGHT OF WAY DELAYS
If, through the failure of the City of Vallejo to acquire or clear right of way, the Contractor sustains loss which could not have been avoided by the judicious handling of forces, equipment and plant, there shall be paid to the Contractor that amount that the Engineer may find to be a fair and reasonable compensation for that part of the Contractor's actual loss, that, in the opinion of the Engineer, was unavoidable, determined as follows:

Compensation for idle time of equipment will be determined in the same manner as determinations are made for equipment used in the performance of extra work paid for on a force account basis, as provided in Section 9-1.03A(3), "Equipment Rental," with the following exceptions:

A. The right of way delay factor for each classification of equipment shown in the State Department of Transportation publication entitled Labor Surcharge And Equipment Rental Rates, which is a part of the Contract, will be applied to that equipment rental rate.

B. The time for which the compensation will be paid will be the actual normal working time during which the delay condition exists, but in no case will exceed 8 hours in any one day.

C. The days for which compensation will be paid will be the calendar days, excluding Saturdays, Sundays and legal holidays, during the existence of the delay, except that when rental of equipment is paid for under the provisions in Section 9-1.03A (3b), "Equipment not on the Work," no payment will be made for right of way delays in conformance with the provisions in this Section 8-1.09.

Actual loss shall be understood to include no items of expense other than idle time of equipment and necessary payments for idle time of workers, cost of extra moving of equipment and cost of longer hauls.

Compensation for idle time of equipment will be determined as provided in this Section 8-1.09 and compensation for idle time of workers will be determined as provided in Section 9-1.03A(1), "Labor," and no markup will be added in either case for overhead and profit. The cost of extra moving of equipment and the cost of longer hauls will be paid for as extra work as provided in Section 4-1.03D.

If performance of the Contractor's work is delayed as the result of the failure of the City of Vallejo to acquire or clear right of way, an extension of time determined pursuant to the provisions in Section 8-1.07, "Liquidated Damages," will be granted.
8-1.10 UTILITY AND NON-HIGHWAY FACILITIES
It is anticipated that some or all of the utility and other non-highway facilities, both above ground and below ground, that are required to be rearranged (as used herein, rearrangement includes installation, relocation, alteration or removal) as a part of the highway improvement will be rearranged in advance of construction operations. Where it is not anticipated that the rearrangement will be performed prior to construction, or where the rearrangement must be coordinated with the Contractor's construction operations, the existing

CITY OF VALLEJO 224 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
facilities that are to be rearranged will be indicated on the drawings or in the special provisions. Where a rearrangement is indicated on the drawings or in the special provisions, the Contractor will have no liability for the costs of performing the work involved in the rearrangement. The Contractor shall not be reimbursed for the costs for coordinating with the utility, railroad and non-highway facilities.

The right is reserved to the City of Vallejo and the owners of facilities, or their authorized agents, to enter upon the highway right of way for the purpose of making those changes that are necessary for the rearrangement of their facilities or for making necessary connections or repairs to their properties. The Contractor shall cooperate with forces engaged in this work and shall conduct operations in such a manner as to avoid any unnecessary delay or hindrance to the work being performed by the other forces. Wherever necessary, the work of the Contractor shall be coordinated with the rearrangement of utility or other non-highway facilities, and the Contractor shall make arrangements with the owner of those facilities for the coordination of the work.

Attention is directed to the possible existence of underground facilities and utilities not indicated in the Contract Documents and to the possibility that utilities may be in a location different from that which is indicated in the Contract Documents. The Contractor shall ascertain the exact location of all utilities , the location of their service laterals or other appurtenances, and of existing service lateral or appurtenances of any other underground facilities prior to doing work.

If the Contractor cannot locate an underground facility or utility whose presence is indicated in the Contract Documents after a diligent search and investigation, the Contractor shall immediately so notify the Engineer in writing. If the facility for which the notice is given is in a substantially different location from that indicated on the drawings or in the special provisions, the additional cost of locating the facility will be paid for as extra work as provided in Section 4-1.03D.

If the Contractor discovers utilities not indicated in the Contract Documents, the Contractor shall immediately give the Engineer and the Utility Company written notification of the existence of those facilities.

The utilities shall be located and protected from damage as directed by the Engineer, and the cost of that work will be paid for as extra work as provided in Section 4-1.03D. The Contractor shall, if directed by the Engineer, repair any damage which may occur to the utilities. The cost of that repair work, not due to the failure of the Contractor to exercise reasonable care or to comply with the terms of the Contract Documents, will be paid for as extra work as provided in Section 4-1.03D. Damage due to the Contractor's failure to exercise reasonable care or comply with the Contract Documents shall be repaired at the Contractor's cost and expense.

Where it is determined by the Engineer that the rearrangement of an underground facility is essential in order to accommodate the highway improvement and the drawings and Specifications do not provide that the facility is to be rearranged, the Engineer will provide for the rearrangement of the facility by other forces or the rearrangement shall be performed by the Contractor and will be paid for as extra work as provided in Section 4-1.03D.

When ordered by the Engineer in writing, the Contractor shall rearrange any utility or other non-highway facility necessary to be rearranged as a part of the highway improvement, and that work will be paid for as extra work as provided in Section 4-1.03D.

Should the Contractor desire to have any rearrangement made in any utility facility, or other improvement, for the Contractor's convenience in order to facilitate the Contractor's construction operations, which rearrangement is in addition to, or different from, the rearrangements indicated on the drawings or in the special provisions, the Contractor shall make whatever arrangements are necessary with the owners of the utility or other non-highway facility for the rearrangement and bear all expenses in connection therewith.

The Contractor shall immediately notify the Engineer of any delays to the Contractor's operations as a direct result of underground main or trunk line facilities which were not indicated on the drawings or in the special provisions or were located in a position substantially different from that indicated on the drawings or in the special provisions, or as a direct result of utility or other non-highway facilities not being rearranged as

CITY OF VALLEJO 225 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
herein provided (other than delays in connection with rearrangements made to facilitate the Contractor's construction operations or delays due to a strike or labor dispute). These delays will be considered right of way delays within the meaning of Section 8-1.09, "Right of Way Delays," and compensation for the delay will be determined in conformance with the provisions in Section 8-1.09. The Contractor shall be entitled to no other compensation for that delay.

Any delays to the Contractor's operations as a direct result of utility or other non-highway facilities not being rearranged as provided in this Section 8-1.10, due to a strike or labor dispute, will entitle the Contractor to an extension of time as provided in Section 8-1.07, "Liquidated Damages." The Contractor shall be entitled to no other compensation for that delay.
8-1.11 TERMINATION OF CONTRACT
The Contract may be terminated by the Director when termination is authorized by Section 7-1.125, "Legal Actions Against the City of Vallejo," Section 7-1.165, "Damage by Storm, Flood, Tsunami or Earthquake," or by other provisions of the Contract which authorize termination. The City of Vallejo also reserves the right to terminate the Contract at any time upon a determination by the Director that termination of the Contract is in the best interest of the City of Vallejo.

If the Director elects to terminate the Contract, the termination of the Contract and the total compensation payable to the Contractor shall be governed by the following:

A. The Engineer will issue the Contractor a written notice signed by the Director, specifying that the Contract is to be terminated. Upon receipt of the written notice, the Contractor will be relieved of further responsibility for damage to the work (excluding materials) as specified in Section 7-1.16, "Contractor's Responsibility for the Work and Materials," and, except as otherwise directed in writing by the Engineer, the Contractor shall:

1. Stop all work under the Contract except that specifically directed to be completed prior to acceptance.

2. Perform work the Engineer deems necessary to secure the project for termination.

3. Remove equipment and plant from the site of the work.

4. Take action that is necessary to protect materials from damage.

5. Notify all subcontractors and suppliers that the Contract is being terminated and that their Contracts or orders are not to be further performed unless otherwise authorized in writing by the Engineer.

6. Provide the Engineer with an inventory list of all materials previously produced, purchased or ordered from suppliers for use in the work and not yet used in the work, including its storage location, and such other information as the Engineer may request.

7. Dispose of materials not yet used in the work as directed by the Engineer. It shall be the Contractor's responsibility to provide the City of Vallejo with good title to all materials purchased by the City of Vallejo hereunder, including materials for which partial payment has been made as provided in Section 9-1.06, "Partial Payments," and with bills of sale or other documents of title for those materials.

8. Subject to the prior written acceptance of the Engineer, settle all outstanding liabilities and all claims arising out of subcontracts or orders for materials terminated hereunder. To the extent directed by the Engineer, the Contractor shall assign to the City of Vallejo all the

CITY OF VALLEJO 226 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
right, title and interest of the Contractor under subcontracts or orders for materials terminated hereunder.

9. Furnish the Engineer with the documentation required to be furnished by the Contractor under the provisions of the Contract including, on projects as to which Federal funds are involved, all documentation required under the Federal requirements included in the Contract.

10. Take other actions directed by the Engineer.

B. Acceptance of the Contract as hereinafter specified shall not relieve the Contractor of responsibility for damage to materials. The Contractor shall continue to be responsible for damage to materials after issuance of the Notice of Termination, except as follows:

1. The Contractor's responsibility for damage to materials for which partial payment has been made as provided in Section 9-1.06, "Partial Payments," and for materials furnished by the City of Vallejo for use in the work and unused shall terminate when the Engineer certifies that those materials have been stored in the manner and at the locations the Engineer has directed.

2. The Contractor's responsibility for damage to materials purchased by the City of Vallejo subsequent to the issuance of the notice that the Contract is to be terminated shall terminate when title and delivery of those materials has been taken by the City of Vallejo.

When the Engineer determines that the Contractor has completed the work under the Contract directed to be completed prior to termination and such other work as may have been ordered to secure the project for termination, the Engineer will recommend that the Director formally accept the Contract.

C. Termination of the Contract shall not relieve the Contractor or surety of their obligation for any claims arising out of the work performed.

D. The total compensation to be paid to the Contractor shall be determined by the Engineer on the basis of the following:

1. The reasonable cost to the Contractor, without profit, for all work performed under the Contract, including mobilization, demobilization and work done to secure the project for termination. In determining the reasonable cost, deductions will be made for the cost of materials to be retained by the Contractor, amounts realized by the sale of materials, and for other appropriate credits against the cost of the work. Deductions will also be made, when the Contract is terminated under the authority of Section 7-1.165, "Damage by Storm, Flood, Tsunami or Earthquake," for the cost of materials damaged by the "occurrence." When, in the opinion of the Engineer, the cost of a Contract item of work is excessively high due to costs incurred to remedy or replace defective or rejected work, the reasonable cost to be allowed will be the estimated reasonable cost of performing that work in compliance with the requirements of the Contract Documents and the excessive actual cost shall be disallowed.

2. A reasonable allowance for profit on the cost of the work performed as determined under Subsection (1), provided the Contractor establishes to the satisfaction of the Engineer that it is reasonably probable that the Contractor would have made a profit had the Contract been completed and provided further, that the profit allowed shall in no event exceed 4 percent of the cost.

CITY OF VALLEJO 227 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025

3. The reasonable cost to the Contractor of handling material returned to the vendor, delivered to the City of Vallejo or otherwise disposed of as directed by the Engineer.

4. A reasonable allowance for the Contractor's administrative costs in determining the amount payable due to termination of the Contract.

All records of the Contractor and the Contractor's subcontractors, necessary to determine compensation in conformance with the provisions in this Section 8-1.11, shall be open to inspection or audit by representatives of the City of Vallejo at all times after issuance of the notice that the Contract is to be terminated and for a period of 3 years, thereafter, and those records shall be retained for that period.

After acceptance of the work by the Director, the Engineer may make payments on the basis of interim estimates pending issuance of the Final Estimate in conformance with the provisions in Section 9-1.07B, "Final Payment and Claims," when, in the Engineer's opinion, the amount thus paid, together with all amounts previously paid or allowed, will not result in total compensation in excess of that to which the Contractor will be entitled. All payments, including payment upon the Final Estimate shall be subject to deduction for prior payments and amounts, if any, to be kept or retained under the provisions of the Contract.
8-2.00 SCOPE OF WORK
The Project is located in various streets throughout the City of Vallejo. The work embraced herein will be done in accordance with the Contract Drawings and Specifications, the 2023 Standard Plans and Specifications of the California Department of Transportation, and the City of Vallejo Standard Specifications and Standard Plans dated December 2011.

SECTION 9: MEASUREMENT AND PAYMENT
9-1.01 MEASUREMENT OF QUANTITIES (NOT USED)
9-1.015 FINAL PAY ITEMS
When an item of work is designated as (F) or (S-F) in the Engineer's Estimate, the estimated quantity for that item of work shall be the final pay quantity, unless the dimensions of any portion of that item are revised by the Engineer, or the item or any portion of the item is eliminated. If the dimensions of any portion of the item are revised, and the revisions result in an increase or decrease in the estimated quantity of that item of work, the final pay quantity for the item will be revised in the amount represented by the changes in the dimensions, except as otherwise provided for minor structures in Section 5.1-1.22, "Measurement." If a final pay item is eliminated, the estimated quantity for the item will be eliminated.

The estimated quantity for each item of work designated as (F) or (S-F) in the Engineer's Estimate shall be considered as approximate only, and no guarantee is made that the quantity which can be determined by computations, based on the details and dimensions shown on the drawings, will equal the estimated quantity. No allowance will be made in the event that the quantity based on computations does not equal the estimated quantity.

In case of discrepancy between the quantity shown in the Engineer's Estimate for a final pay item and the quantity or summation of quantities for the same item shown on the drawings, payment will be based on the quantity shown in the Engineer's Estimate.

Under no circumstances will Contractor be entitled to payment for any final pay quantity that is greater than the unit quantity price for the final pay quantity item set forth in the proposal form. 9-1.02 SCOPE OF PAYMENT

The provisions in Section 9-1.03A(1), "Labor," shall not apply to operators of rented dump trucks.

CITY OF VALLEJO 234 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025

To the total of the rental costs for fully maintained and operated dump trucks, including labor, there will be added a markup of 15 percent. An additional markup of 5 percent will be added by reason of performance of the work by a subcontractor. No separate markup will be made for labor.

The provisions in Section 9-1.03A(3c), "Owner-Operated Equipment," shall not apply to dump truck rentals. 9-1.03B WORK PERFORMED BY SPECIAL FORCES OR OTHER SPECIAL SERVICES When the Engineer and the Contractor, by agreement, determine that a special service or an item of extra work cannot be performed by the forces of the Contractor or those of any of the Contractor's subcontractors, that service or extra work item may be performed by a specialist. 9-1.03C RECORDS
The Contractor and all subcontractors shall maintain records in such a manner as to provide a clear distinction between the direct costs of extra work paid and the costs of other operations.

From the above records, the Contractor shall furnish the Engineer completed daily extra work reports, either on forms furnished by the City of Vallejo or on computerized facsimiles of the City of Vallejo's forms acceptable to the Engineer, for each day's extra work to be paid for on a force account basis.

The daily extra work reports shall provide names, identifications, and classifications of all workers, the hourly rate of pay and hours worked, and the size, type and identification number of equipment, and hours operated.

Material charges shall be substantiated by valid copies of vendor's invoices. The invoices shall be submitted with the daily extra work reports, or if not available, the invoices shall be submitted within 30 days after the submittal of the daily extra work report or 30 days after the date of delivery of the material, whichever occurs first. Contractor waives payment for material charges not substantiated by valid copies of vendor’s invoices submitted within the times provided.

Daily extra work reports shall be signed by the Contractor or the Contractor's authorized representative and shall be submitted to the City on the day the work is performed, or within 24 hours if authorized by the Engineer. Daily extra work reports shall be signed by the designated representative of the City to acknowledge the labor hours, materials, and equipment used to perform the work. Signature by the City’s representative does not constitute approval for payment. All daily extra work reports are subject to review and approval by the Engineer for conformance to the Contract Documents prior to payment. The City reserves the right to adjust the amount to be paid for extra work based upon daily extra work reports at any time prior to project acceptance, even if payment has been made under a progress payment. Contractor waives payment for that portion of Force Account work in which a daily extra work report has not been signed by the City’s designated representative and/or submitted to the City within the time specified above.

The Engineer will compare the Engineer's records with the completed daily extra work reports furnished by the Contractor and make any necessary adjustments. When these daily extra work reports are agreed upon and signed by both parties, the reports shall become the basis of payment for the work performed but shall not preclude subsequent adjustment based on a later audit by the City of Vallejo.

The Contractor's and all subcontractors’ records pertaining to the Project shall be open to inspection or

CITY OF VALLEJO 235 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
audit by representatives of the City of Vallejo, during the life of the Contract and for a period of not less than 3 years after the date of acceptance thereof, and the Contractor and all subcontractors shall retain those records for that period. Where payment for materials or labor is based on the cost thereof to forces other than the Contractor, the Contractor shall make every reasonable effort to ensure that the cost records of those other forces will be open to inspection and audit by representatives of the City of Vallejo on the same terms and conditions as the cost records of the Contractor. If an audit is to be commenced more than 60 days after the acceptance date of the Contract, the Contractor will be given a reasonable notice of the time when the audit is to begin.

9-1.04 (BLANK)
9-1.05 STOP NOTICES
The City of Vallejo may at its option and at any time retain out of any amounts due the Contractor, sums sufficient to cover claims filed pursuant to Section 3179 et seq. of the Civil Code. In cases where the contractor chooses to Bond around the Stop Notice, the Bond shall be of a form approved by the City. 9-1.06 PARTIAL PAYMENTS
The City of Vallejo, once in each month, shall cause an estimate in writing to be made by the Engineer.

The estimate shall include the total amount of work done and acceptable materials furnished, provided the acceptable materials are listed as eligible for partial payment as materials in the special provisions and are furnished and delivered by the Contractor on the ground and not used or are furnished and stored for use on the Contract, if the storage is within the City of Vallejo and the Contractor furnishes evidence satisfactory to the Engineer that the materials are stored subject to or under the control of the City of Vallejo, to the time of the estimate, and the value thereof. The estimate shall also include any amounts payable for mobilization. Daily extra work reports furnished by the Contractor less than 5 calendar days, not including Saturdays, Sundays and legal holidays, prior to the preparation of the monthly progress estimate shall not be eligible for payment until the following month's estimate.

The amount of any material to be considered in making an estimate will in no case exceed the amount thereof which has been reported by the Contractor to the Engineer on City of Vallejo-furnished forms properly filled out and executed, including accompanying documentation as therein required, less the amount of the material incorporated in the work to the time of the estimate. Only materials to be incorporated in the work will be considered. The estimated value of the material established by the Engineer will in no case exceed the Contract price for the item of work for which the material is furnished.

The application for payment shall be prepared in a form acceptable to Engineer and shall contain itemized amounts in accordance with the Contract Documents. The applications for payment shall not include requests for payment on account of changes which have not been authorized by Change Orders, or for amounts Contractor does not intend to pay a subcontractor because of a dispute or other reason.

If requested by the City of Vallejo, an application for payment shall be accompanied by a summary showing payment that will be made to subcontractors covered by such application, and unconditional waivers and releases of claims and stop notices, from each subcontractor listed in the preceding application for payment covering sums disbursed pursuant to that preceding application for payment.

Contractor warrants that upon submittal of an application for payment, all work has been performed in strict compliance with the Contract Documents, and all work for which certificates of payment have been previously issued and payment has been received from City of Vallejo, shall be free and clear of all claims, stop notices, security interests, and encumbrances in favor of Contractor, subcontractors or other persons or firms entitled to make claims by reason of having provided labor, materials, or equipment related to the work.

Payment of all, or any part, of an application for payment may be withheld, a certificate of payment may be withheld, all or part of a previous certificate for payment may be nullified and that amount withheld from a current certificate for payment, or the City of Vallejo may withhold from payment, on account of any of the following:
 Defective work not remedied.
 Third-party claims against Contractor or City of Vallejo arising from the acts or omissions of Contractor or subcontractors.
 Stop notices.
 Failure of Contractor to make timely payments due to subcontractors for material or labor.  A reasonable doubt that the work can be completed for the balance of the Contract price then unpaid.
 Damage to the City of Vallejo or others for which Contractor is responsible.  Reasonable evidence that the work cannot be completed within the Contract time, and the unpaid balance of the Contract price would not be adequate to complete the work and cover City of Vallejo's damages for the anticipated delay.
 Failure of Contractor to maintain, update, and submit record documents.  Failure of Contractor to submit schedules or their updates as required by the Contract Documents.  Performance of the work by Contractor without properly processed shop drawings.  Liquidated damages assessed.
 Any other failure of the Contractor to perform its obligations under the Contract Documents.

Contractor understands and agrees that Contractor will be paid only from this special fund and if for any reason this fund is not sufficient to pay Contractor, Contractor will not be entitled to payment. The availability of money in this fund, and City of Vallejo's ability to draw from this fund, are conditions precedent to City of Vallejo's obligation to make payments to Contractor.

Within thirty (30) days of receipt of an approved certificate for payment, properly executed by the Contractor, City of Vallejo’s Engineer and Director, City of Vallejo agrees to pay Contractor, subject to all of the terms and conditions of these Contract Documents, an amount equal to ninety five percent (95%) of the sum of the following (less any amounts withheld as permitted by the Contract Documents):

The Contractor shall be the beneficial owner of any securities substituted for moneys withheld and shall receive any interest thereon. Upon satisfactory completion of the Contract, the securities shall be returned to the Contractor.

Alternatively, upon the Contractor's request, the City of Vallejo will make payment of retentions earned directly to the escrow agent. The Contractor may direct the investment of the payments into securities, and the Contractor shall receive the interest earned on the investments upon the same terms provided for securities deposited by the Contractor. Upon satisfactory completion of the Contract, the Contractor shall receive from the escrow agent all securities, interest and payments received by the escrow agent from the City of Vallejo.

Upon written request of an escrow agent that has not been approved by the City of Vallejo under subdivision (c) of Section 10263 of the Public Contract Code, the City of Vallejo will provide written notice to that escrow agent within 10 business days of receipt of the request indicating the reason or reasons for not approving that escrow agent. The payments will be deposited in a trust account with a Federally chartered bank or savings association within 24 hours of receipt by the escrow agent. The Contractor shall not place any retentions with the escrow agent in excess of the coverage provided to that escrow agent pursuant to subdivision (b) of Section 17314 of the Financial Code. In all respects not inconsistent with subdivision (c) of Section 10263 of the Public Contract Code, the remaining provisions of Section 10263 of the Public Contract Code shall apply to escrow agents acting pursuant to subdivision (c) of Section 10263 of the Public Contract Code.

Securities eligible for investment shall include those listed in Section 16430 of the Government Code, bank or savings and loan certificates of deposit, interest-bearing demand deposit accounts, standby letters of credit or any other security mutually agreed to by the Contractor and the City of Vallejo.

The Claims procedures set forth in this section 9-1.07C are in addition to any claims procedures or rights available to Contractor pursuant to California Public Contract Code section 20104-20104.6 or California Public Contract Code section 9204 and Contractor’s exhaustion of its administrative remedies pursuant to this section 9-1.07C is a condition precedent to Contractor pursuing any claim pursuant to California Public Contract Code section 20104-20104.6 or California Public Contract Code section 9204 A. General. A “Claim” means a written demand or written assertion by Contractor to adjust, alter, modify, or otherwise change the Contract price or the Contract time, or both. All claims filed hereunder shall strictly comply with all requirements of the Contract Documents.

In order to qualify as a “Claim,” the written demand must state that it is a claim submitted under Section 9-

1.07C of the Contract Documents. A letter, voucher, invoice, payment application, or other routine or authorized form of request for payment is not a Claim under the Contract Documents. If such a request is disputed as to liability or amount, then the disputed portion of the submission may be converted to a Claim under the Contract Documents by submitting a separate claim in compliance with claim submission requirements.

A Claim must be stated with specificity, including identification of the event or occurrence giving rise to the Claim, the date of the event, and the asserted affect on the Contract price and the Contract time, if any.

The Claim shall include adequate supporting data. Adequate supporting data for a Claim for an adjustment of the Contract time shall include scheduling data demonstrating the impact of the event on the controlling operation and completion of the Project. Adequate supporting data for a Claim for an adjustment in the Contract price shall include a detailed cost breakdown of items included within the Claim and documentation supporting each item of cost.

Notwithstanding and pending the resolution of any Claim, the Contractor shall diligently prosecute the disputed work to final completion of the work. Contractor shall impose the Claim notice and documentation requirements in this Contract on Contractor’s subcontractors of all tiers, and require them to submit to the Contractor all Claims against Contractor and/or City within the times and containing the documentation required by these provisions. The Claim notice and documentation procedure described in these provisions applies to all claims and disputes arising under the Contract Documents, whether or not specifically referred to in any specific portion of the Contract.

If additional information or details are required by the Engineer to determine the basis and amount of any Claims, the Contractor shall furnish additional information or details so that the additional information or details are received by the Engineer no later than the fifteenth day after receipt of the written request from the Engineer. If the fifteenth day falls on a Saturday, Sunday or legal holiday, then receipt of the information or details by the Engineer shall not be later than close of business of the next business day. Contractor understands and agrees that failure to submit the information and details to the Engineer within the time specified shall be result in Contractor waiving that Claim.

The Contractor and all subcontractors shall keep full and complete records of the costs and additional time incurred for any work for which a Claim for additional compensation is made. The Engineer or any designated claim investigator or auditor shall have access to those records and any other records as may be required by the Engineer to determine the facts or contentions involved in the claims. Contractor agrees that failure to permit access to those records waives Contractor’s Claims.

The City of Vallejo, or its authorized representatives, shall have access, upon reasonable notice, during normal business hours, to Contractor and subcontractors' books, documents and accounting records, including but not limited to, bid worksheets, bids, subcontractor bids and proposals, estimates, cost accounting data, accounting records, payroll records, time sheets, canceled checks, profit and loss statements, balance sheets, project correspondence including but not limited to all correspondence between Contractor and its sureties and subcontractors/vendors, project files, scheduling information, and

CITY OF VALLEJO 240 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
other records of the Contractor and all subcontractors directly or indirectly pertinent to the work, original as well as change and claimed extra work, to verify and evaluate the accuracy of cost and pricing data submitted with any change order, prospective or completed, or any claim for which additional compensation has been requested or claim has been tendered. Such access shall include the right to examine and audit such records, and make excerpts, transcriptions, and photocopies at City of Vallejo's cost.

The parties agree that in the event Contractor or any subcontractor fails to comply with this section, it would be difficult for the City of Vallejo to determine its actual damages; therefore, Contractor agrees to pay City of Vallejo, as liquidated damages, the sum of Two hundred fifty dollars ($250.00), which Contractor agrees is reasonable under the circumstances, for each and every calendar day which Contractor or a subcontractor fails or refuses to provide the City of Vallejo, access to the documents, records and materials specified in this section.

B. Disputes
Contract Interpretation Disputes: Should it appear to the Contractor that the work is to be performed or any of the matters relative to the Contract Documents are not satisfactorily detailed or explained therein, or should any questions arise as to the meaning or intent of the Contract Documents, the Contractor shall give written notice to the City of Vallejo. The Contractor shall bear all costs incurred in the giving of such notice.

All issues regarding the interpretation of the drawings or specifications shall be referred to the City for interpretation. The City shall have the right but not the obligation to affirm or disaffirm any interpretation of the drawings or specifications, which affirmance or disaffirmance shall be final. If the Contractor should disagree with the City’s decision, the Contractor’s sole and exclusive remedy is to file a Claim in accordance with these provisions.

Work Disputes: Should any dispute arise under the Contract Documents respecting the true value of any work performed, the implementation of the Work required by the Contract Documents, any Work omitted, any extra work which the Contractor may be required to perform or time extensions, respecting the size of any payment to the Contractor during the performance of the Contract Documents, or of compliance with Contract Documents procedures, the dispute shall be decided by the City of Vallejo and its decision shall be final and conclusive. If the Contractor disagrees with the City’s decision, the Contractor’s sole and exclusive remedy is to file a claim in accordance with these provisions.

C. Delays. As used herein, the following terms shall have the following meanings:
"Excusable Delay" means any delay of the completion of the Project beyond the expiration of the Contract time caused by conditions beyond the control and without the fault or negligence of the Contractor such as strikes, embargoes, fire, unavoidable casualties, unusual delays in transportation, national emergency, and stormy and inclement weather conditions in which the work cannot continue. The financial inability of the Contractor or any subcontractor and default of any subcontractor, without limitation, shall not be deemed conditions beyond the Contractor's control. An Excusable Delay may entitle the Contractor to an adjustment in the Contract time.
"Compensable Delay" means any delay of the completion of the work beyond the expiration date of the Contract time caused by the gross negligence or willful acts of the City of Vallejo, and which delay is unreasonable under the circumstances involved, and not within the contemplation of the parties. A Compensable Delay may entitle the Contractor to an extension of the Contract time and/or Contract price.

Except as provided herein, the Contractor shall have no claim for damage or compensation for any delay, interruption, hindrance, or disruption.
"Unexcusable Delay" means any delay of the completion of the Project beyond the expiration of the Contract time resulting from causes other than those listed above. An Unexcusable Delay shall not entitle the Contractor to an extension of the Contract time or an adjustment of the Contract price.

The Contractor may make a Claim for an extension of the Contract time, for an Excusable Delay or a

CITY OF VALLEJO 241 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
Compensable Delay, subject to the following:

1. If an Excusable Delay and a Compensable Delay occur concurrently, the maximum extension of the Contract time shall be the number of days from the commencement of the first delay to the cessation of the delay which ends last.

2. If an Unexcusable Delay occurs concurrently with either an Excusable Delay or a Compensable Delay, the maximum extension of the Contract time shall be the number of days, if any, by which the Excusable Delay or the Compensable Delay exceeds the Unexcusable Delay.

3. If an Unexcusable Delay occurs concurrently with both an Excusable Delay and a Compensable Delay, the maximum extension in the Contract time shall be the number of days, if any, by which the number of days determined pursuant to Subparagraph (a) exceeds the number of days of the Unexcusable Delay.

4. For a Compensable Delay, the Contractor shall only be entitled to an adjustment in the Contract Sum in an amount equal to: (1) the actual additional labor costs, material costs, and unavoidable equipment costs incurred by the Contractor as a result of the Compensable Delay, plus the actual additional wages or salaries and fringe benefits and payroll taxes of supervisory and administrative personnel necessary and directly employed at the Project site for the supervision of the work during the period of Compensable Delay; or (2) the Contractor’s Daily Delay Damages set forth in the Bid Form, whichever is less. Except as provided herein, the Contractor shall have no claim for damage or compensation for any delay, interruption, hindrance, or disruption. There shall be no Compensable Delay unless the event or occurrence giving rise to the Compensable Delay extends the actual completion of the Project past the Contract time.

The parties agree that the City of Vallejo's exercise of its right to order changes in the work, regardless of the extent and number of changes, or to suspend the work, is within the contemplation of the parties and shall not be the basis for any Claim for Compensable Delay. The rights of the Contractor to adjustments of the Contract time and the Contract sum, based on changes ordered in the work or suspension of the work, shall be governed by this provision.

Notwithstanding the making of any Claim or the existence of any dispute regarding any Claim, Contractor shall not cause any delay, cessation, or termination in or of Contractor's performance of the work but shall diligently proceed with performance of the work in accordance with the Contract Documents.

Contractor agrees that the daily Contractor Daily Delay Damages as set forth in the Proposal Form shall be full compensation to Contractor, all subcontractors and anyone for whom they may be legally responsible, for each day of delay that may be caused by City of Vallejo or anyone for whom City of Vallejo is legally responsible, including but not limited to, extended field costs, extended home overhead costs, impact, inefficiency, unabsorbed home office overhead, underabsorbed home office overhead, hindrance, disruption or any other damage arising from delay, no matter how characterized and regardless of the cause, extent or duration of the delay. Inclusion of Contractor Daily Delay Damages within the Proposal Form is solely for the purpose of determining the low Bidder and establishing the City of Vallejo’s maximum daily liability as a result of City of Vallejo delays to Contractor, if any, and City of Vallejo has no obligation to pay any Contractor Daily Delay Damages except as provided for in these Contract Documents for Compensable Delays. In the event that City of Vallejo becomes liable to Contractor for compensable delays, City of Vallejo agrees to pay Contractor the Daily Delay Damages set forth in the Proposal Form or Contractor’s actual daily delay damages, whichever is less, for each day of Compensable Delay as provided for by these Contract Documents.

D. Claim Procedures. Should any clarification, determination, action or inaction by the City, Work, or any event, in the opinion of the Contractor, exceed the requirements of or not comply with the Contract Documents, or otherwise result in the Contractor seeking additional compensation in time or money for any reason (collectively “Disputed Work”), then the Contractor and the City shall make good faith attempts to resolve informally any and all such issues and/or disputes. The Contractor

CITY OF VALLEJO 242 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
must file a written Notice of Potential Claim with the City on the form provided in the Contract Documents before commencing the Disputed Work, or within seven (7) calendar days after Contractor’s first knowledge of the Disputed Work, whichever is earlier, stating clearly and in detail its objection and reasons for contending the Work or interpretation is outside the requirements of the Contract Documents. If a written Notice of Potential Claim is not filed within this time period, or if the Contractor proceeds with the Disputed Work without first having filed the notice required by these provisions, the Contractor shall waive any rights to further claim on the specific issue.

The City will review the Contractor’s timely Notice of Potential Claim and provide a decision. The City may require supplemental information from the Contractor to clarify that contained in the Notice of Potential Claim. If, after receiving the City’s decision, the Contractor disagrees with the decision, the Contractor shall so notify the City, in writing, within seven (7) calendar days after receiving the decision, that a formal Claim will be filed. The Contractor shall submit the Claim in the form specified herein and all arguments, justification, costs or estimates, schedule analyses, and detailed documentation supporting the Contractor’s position within thirty (30) calendar days after receiving the City’s decision on the Notice of Potential Claim.

The Contractor’s failure to furnish notification within seven (7) calendar days and all justifying documentation within thirty (30) calendar days will result in the Contractor waiving all rights to the subject Claim.

If Disputed Work persists longer than thirty (30) calendar days after receiving the City’s decision on the Notice of Potential Claim, then the Contractor shall, every thirty (30) calendar days until the Disputed Work ceases, submit to the City a document titled “Claim Update” which shall update and quantify all elements of the Claim as completely as possible. The Contractor’s failure to submit a Claim Update or to quantify all costs and impacts every thirty (30) days shall result waiver of that portion of the Claim for that thirty (30) day period. Claims or Claim Updates stating that damages will be determined at a later date shall not comply with the requirements of these provisions and shall result in the Contractor waiving such Claim(s) and/or Claim Updates.

All Claims must be submitted to Engineer before the issuance of the final estimate. Contractor hereby expressly waives all Claims not submitted, in complete and proper form, on or before the date of issuance of the final estimate.

Upon receipt of the Contractor’s formal Claim including all arguments, justifications, costs or estimates, schedule analyses, and documentation supporting the Contractor’s position as previously stipulated, the City or its designate will review the Claim and render a final determination. If the Contractor’s Claims at project completion total less than $375,000, then claims resolution shall proceed in the manner prescribed by Article 1.5, Chapter 1, Part 3 of Division 2 of the California Public Contract Code.

Claims shall be calculated in the same manner as extra work using the procedures set forth in Section 9-

1.03 “Force Account Payment.” This method applies in all cases of Claims, regardless of type, whether in negotiation, arbitration, litigation, and even applies in the event of fault, negligence, strict liability, or tort claims of all kinds, including strict liability or negligence. No other costs arising out of or connected to with the performance of Claims, of any nature, may be recovered by the Contractor. Except where provided by law, or elsewhere in these Contract Documents (if applicable), the City shall not be liable for special or consequential damages, and Claims shall not include special or consequential damages. Contractor shall be limited in its recovery on Claims to the calculations set forth in Section 9-1.03 of these provisions.

Pull boxes located in ramp construction areas shall be removed and replaced and set to finished grade at same location, unless otherwise directed by the Engineer.

H. Placing and Finishing
Contractor shall maintain records for placement of all concrete. Concrete shall be placed in dry conditions; keep excavations free of water, ice, loose soil or debris. There shall not be additional water added to the mix without the written permission from the Engineer and Testing Laboratory.

Do not place concrete if rain is forecasted for less than 12 hours after the pour; concrete damaged by rain shall be removed and replaced at the Contractor’s expense, including any other work that needs to be redone as a consequence of this replacement.

Contractor shall handle concrete from mixer to place of deposit as rapidly as possible; using methods to prevent separation or loss of ingredients. Deposit in final position; avoid re-handling or flowing. Contractor shall neither place partially hardened concrete nor wheel placement containers directly on top of reinforcing steel. The concrete shall be deposited on a moist grade in such a manner as to require as little re-handling as possible. Workmen shall not be allowed to walk in the freshly mixed concrete with boots or shoes coated with earth or foreign substances.

Contractor shall place concrete continuously between predetermined expansion, contraction, and construction joints. Contractor shall not break or interrupt placement of concrete in a manner that causes cold joints to occur. All low areas shall be filled during screeding and floating operations; do not add material after the concrete has begun to set.

Any light pole, fire hydrant, or vertical pole footings exposed from lowering adjacent concrete grades related to placement of ramp shall be neatly formed and finished and not leave a rough unfinished surface and shall be included in this bid item.

Before final finishing is completed and before the concrete has taken its initial set, the edges shall be carefully finished with the radius shown on the plans or a radius to match the existing construction.

Concrete shall be thoroughly consolidated against and along the faces of all forms and adjacent concrete. After the forms are removed, excess concrete below the form surface shall be removed to be flush with the form face.

All new concrete shall match existing facilities in texture, color, and appearance. Sidewalk shall have a medium broom finish cross-wise to the direction of travel. Curbs and gutters shall have a light wood float finish. The Contractor shall clean at his expense all discolored concrete. The concrete may be cleaned by abrasive blast cleaning or other methods approved by the Engineer.

Repairs shall be made by removing and replacing the entire unit between scoring lines or joints.

Contractor shall thoroughly work concrete around reinforcement, embedded components and into corners of forms, consolidate concrete by internal vibration, only. Contractor shall not puddle, tamp or vibrate concrete which has already taken initial set or continue long enough cause segregation of material.

Contractor shall consolidate concrete slabs on grade by spading and puddling and internal vibration. Contractor shall consolidate concrete in forms with high-speed internal vibrators.

J. Concrete Protection
The Contractor shall always have materials available to protect the surface of the fresh concrete against rain. These materials shall consist of burlap, curing paper, or plastic sheeting. If plastic sheeting is used, it shall not be allowed to contact finished concrete surfaces.

The Contractor shall also protect the concrete against traffic and vandalism. If the concrete is damaged or vandalized, the Contractor shall make the necessary repairs at its own expense. The repair procedure for damaged or vandalized concrete shall be approved in advance by the Engineer.

K. Curing
Concrete shall be cured by protecting it against loss of moisture, rapid temperature change, and mechanical injury for at least three days after placement through impervious membrane means.

White or clear liquid membrane compound shall be used. After finishing operations have been completed, the entire surface of the newly placed concrete shall be covered by the curing medium.

The edges of the concrete exposed by the removal of forms shall be protected immediately to provide these surfaces with continuous curing treatment. The concrete shall be allowed to cure for seventy-two hours prior to placing adjacent asphalt concrete.

L. Joints
New sidewalk, curb or gutter shall be connected to adjacent existing concrete using 12-inch long by 1/2-inch diameter steel dowels (#4 rebar is acceptable) in tight fitting holes drilled into the existing concrete (approximately 6 inches into adjacent sidewalk, curb and gutter, or 4” into the back of curb).

Half inch-thick expansion joints shall be placed on both sides of driveway approaches, curb and sidewalk return points, fixed structures (including storm drain inlets), and at approximately 24 feet on center. An expansion joint shall also be placed between the back of the sidewalk or driveway approach and any driveway walkway or foundation poured against it. Weakened plane joints shall be placed at all inside corners (including tree wells and parkway strips), both sides of utility boxes and wherever shrinkage would concentrate stresses, and otherwise at no more than 12 feet on centers.

Expansion joint material shall completely separate the concrete all the way to the forms and down to the base material, and it shall be cut to match curved surfaces. Expansion joints within sidewalk, curb and gutter shall have steel dowels joining the concrete on both sides of the joint. These dowels shall be smooth, or on one side of the joint shall have the dowels wrapped with sleeves to allow them to move.

One quarter inch deep by one quarter inch radius score lines in sidewalks shall be evenly spaced at approximately 4 feet apart or as directed by the Engineer. In addition, a similar score mark shall be placed 6 inches back from the face of curb where curb and sidewalk are poured monolithically.

Work covered by this section includes grinding of the existing pavement with various thicknesses. Work shall be in conformance with Section 42-3, “Grinding,” of the Caltrans Standard Specifications.

Wedge grinding and conform grinding as shown on the plans and as directed by the City to accommodate actual field conditions.

Existing asphalt concrete pavement shall be removed at the locations and to the dimensions shown on the plan and disposed of as specified herein.

Pavement removal shall be performed with a pavement grinder. No other construction equipment will be allowed on the subgrade unless approved by the Engineer. No rubber tired equipment shall be allowed on the subgrade. Contractor shall exercise due caution when grinding or removing existing asphalt concrete around existing utility castings, or manholes. Following grinding of the asphalt concrete adjacent to castings or manholes, the contractor shall use hand working tools as necessary to remove any remaining asphalt concrete.

The depth, width and shape of the cut shall be indicated on the typical cross-sections, details or as directed by the Engineer. The final cut shall result in a uniform surface conforming to the typical cross-sections and details. The outside lines of the planed area shall be neat and uniform. Planing asphalt concrete pavement operations shall be performed without damage to the surfacing to remain in place.

When transverse joints are made in the pavement at conform lines; no drop-off shall remain between the existing pavement and planed area when the pavement is opened to public traffic. If asphalt concrete has not been placed to the level of existing pavement before the pavement is to be opened public traffic, a temporary asphalt concrete taper shall be constructed. Asphalt concrete for temporary tapers shall be placed to the level of the existing pavement and tapers on a slope of 30:1, or flatter, to the level of the planed area.

The depth, width and shape of the cut shall be indicated on the typical cross-sections, details or as directed by the Engineer. The final cut shall result in a uniform surface conforming to the typical cross-sections and details. The outside lines of the planed area shall be neat and uniform. Planing asphalt concrete pavement operations shall be performed without damage to the surfacing to remain in place.

Asphalt concrete for temporary tapers shall be constructed of commercial quality asphalt concrete or cold mix asphalt concrete and may be spread and compacted by any method that will produce a smooth riding surface. Temporary asphalt concrete tapers shall be maintained continuously and when no longer needed completely removed, including the removal of all loose material from the underlying surface, before placing the permanent surfacing. Such removed material shall be dispose of in accordance with Section 6-1.20 "Disposal of Material Outside the Highway Right of Way," of the General Provisions.

CITY OF VALLEJO 291 STREETS OVERLAY/PAVEMENT MAINTENANCE & REHABILITATION MEASURE P PROJECT – MP2025
The Contractor shall note that there are trees, shrubs and vegetation near areas intended for asphalt removal. The Contractor's operation, including the size of the grinding equipment, shall be such, so as to ensure that existing trees are not damaged. Where limited clearance under the trees prevents the use of a grinder, excavation shall be performed by an alternate method as approved by the Engineer. Alternate methods may include jackhammering and removal of existing pavement and base materials by hand, or by use of smaller grinding equipment.

The material planed from the roadway surface, including material deposited in existing gutters or on the adjacent traveled way, shall be removed and disposed of outside the highway right-of-way in accordance with Section 6-1.20 "Disposal of Material Outside the Highway Right of Way," of the General Provisions.

Removal operations of cold-planed material shall be concurrent with planning operations and follow within 50 feet of the planer, unless otherwise directed by the Engineer. The Contractor shall provide sediment control measures to prevent sediment from entering the storm drain system.

Materials
The wedge grinding machine shall have a cutter head at least 5 feet in width and have automatic controls that accurately establish or maintain existing profile grades at each edge of the cutter by referencing from the existing pavement or an independent grade reference. The planning machine shall be operated in such a way so as not to produce smoke or fumes.

Execution
Unless otherwise shown on the plans, standard edge grinding for the various conditions shall be per the project details.

The outside lines of the planed area shall be neat and uniform. The roadway surface to remain in place shall not be damaged in any way. The Contractor shall replace the teeth on the planning machine when necessary, in order to provide a final cut with uniform grooves and ridges. The final cut shall result in a uniform surface and meet the approval of the City.

Contractor shall place and maintain warning signs and temporary AC patch material to serve as “ramps” at all pedestrian and vehicular crossings over the entire length of grinding.

It is the Contractor’s responsibility to ascertain the location of, and avoid damage to, all manholes, water valves, water meter boxes, utility boxes, utility vaults, gas valves, anode covers, handhole covers, survey monument covers and adjacent concrete improvements. All improvements damaged by the grinding operation shall be replaced at the Contractor’s expense.

The material ground from the roadway surface, including material deposited in existing gutters or on the adjacent travel way, shall be immediately removed from the work site and disposed of in a legal and proper manner. The planer shall pick up the material as it progresses, or a removal crew shall follow within 50 feet of the grinding operations to pick up the material. All grinding work, including standard wedge cut, shall be done on an as-needed basis, and as directed by the City. The nature of this work is that grinding and wedge cut work cannot always be predetermined. Regardless of whether grinding work is shown or not shown on the plans, the City shall have the right to increase or decrease scope of work for this contract item.

All existing pavement shall be trimmed as required to provide a smooth face to abut the new pavement.

The ground areas shall be smooth and have a dry and properly prepared surface prior to the start of paving operations. It shall be free from all loose screening and other loose or foreign material.
