SECTION 2 – SCOPE AND CONTROL OF THE WORK2-1 AWARD AND EXECUTION OF CONTRACTAward and execution of contract will be as specified in the Bidding Requirements. 2-2 ASSIGNMENT OF PAYMENT Contractor agrees she/he will not assign the payment of any monies due him/her from the City under the terms of this contract to any other individual(s), corporation(s), or entity(s). The City retains the right to pay any and all monies due Contractor directly to Contractor. 2-3 SUBCONTRACTS As provided in Sections 4100 to 4114, inclusive of the California Public Contract Code, each bidder shall file with his/her bid the name and location of the place of business of each Subcontractor who will perform Work or labor or render service to the Contractor in or about the construction of the Work or improvement, or a subcontractor licensed by the State of California who, under subcontract to the prime contractor, specially fabricates and installs a portion of the work or improvement according to detailed drawings contained in the plans and specifications, in an amount in excess of one-half of one percent of the amount of the total bid or, in the case of bids or offers for the construction of streets or highways, including bridges, in excess of one-half of one percent (0.5%) of the Contractor’s total bid or ten thousand dollars ($10,000), whichever is greater. Only one Subcontractor shall be listed for each portion of the Work, which portion shall be defined in the Proposal. In each instance, the nature and extent of the Work to be sublet or subcontracted shall be described. The failure of the bidder to specify a Subcontractor, or the listing of more than one Subcontractor for the same portion of the Work, constitutes an agreement by the bidder that she/he is fully qualified to perform that portion himself/herself, and that, if awarded the contract, she/he shall perform that portion himself/herself. The Contractor shall not substitute any subcontractor in place of the Subcontractors designated in the original bid, without the consent of the City.

Violation of any of the above provisions is a violation of the contract, and the City may cancel the contract or assess the Contractor a penalty of not more than ten percent (10%) of the subcontract involved. Notice and hearing shall be afforded the Contractor as required by Section 4110 of the California Public Contract Code.

No extra charges or compensation will be allowed for grade variation or discrepancies except by written agreement before construction begins. Initiation of Work shall indicate Contractor's verification of existing grade elevations and acceptance of existing Site surface characteristics. While it is intended that information pertaining to physical conditions which may affect the cost of the proposed work will be shown on the Plans or indicated in the Specifications, the City does not warrant the completeness or accuracy of such information. It is the Contractor's responsibility to ascertain the existence of any such conditions affecting the cost of the Work which would have been disclosed by reasonable examination of the Site.No test, investigation, statement or estimate of a factual situation incorporated, or not incorporated, in the contract shall be relied on by the Contractor. Any test, investigation statement or estimate of fact incorporated in the contract shall be considered by the Contractor to be a suggestion only and she/he shall request access to the underlying or background informative material or source and shall arrive at his/her own opinion thereon, including his/her determination of how reliable might be any conclusion appearing in (or inferred from) the contract. When the Contractor has obtained or actually viewed any "As-Built" or similarly final or accepted drawing or map of any facility constructed for and under inspection by the City, the Contractor may rely upon the drawing or map. No drawing or map obtained from, through or by the City of any facility installed on or off of public property by a private Person or Utility, and not by and for-the City, may be relied on by the Contractor; the accuracy of such documents must be questioned. For convenience, these Specifications are arranged in the several sections indicated, but such separation shall not be considered as the limits of the Work required of any separate trade. The terms and conditions of such limitations are wholly between the Contractor and his/her Subcontractors. In general, the drawings will indicate dimensions, position and kind of construction, and the written Specifications will indicate qualities and methods. Any Work indicated on the drawings and not mentioned in the written Specifications, or vice versa, shall be furnished as though fully set forth in both. Work not particularly detailed, marked or specified, shall be as similar parts that are detailed, marked or specified. Figured dimensions on the scale drawings and the full size details shall govern.
City of Fresno Dept. of Public Works2-5A9 May 2024
Contractor represents to City that prior to submitting its bid and in a timely manner to allow for resolution by an addendum, Contractor (i) exercised due diligence in performing a constructability review of the Contract Documents in accordance with industry standards; (ii) submitted on the Bid Question Form in the Instruction to Bidders, for resolution by addendum, a request for clarification and stating in detail any lack of definition and all errors, omissions, conflicts and insufficiencies in the Contract Documents discovered during such constructability review; and (iii) obtained written assurances from each of his/her Subcontractors that they exercised the same due diligence in performing such a constructability review and submitted a Bid Question Form in accordance with the foregoing, either directly or through the Contractor. Prior to the commencement of the Work, the Contractor and each of his/her Subcontractors shall submit to the Engineer a written, signed report stating in detail any lack of definition, errors, omissions, conflicts and insufficiencies in the Contract Documents discovered since said constructability review and not reasonably discoverable in such a review. The report covering any subdivision of Work assigned to a Subcontractor shall be prepared and submitted by such Subcontractor through the Contractor, who shall execute on such report his/her approval thereof and shall submit it to the Engineer with the Contractor's report. If no deficiencies were discovered by the Contractor or any Subcontractor, a report shall be filed nevertheless, stating that fact. It shall be the duty of the Contractor to require each Subcontractor to comply with this subparagraph.After receipt of the reports required by the subparagraph above, the Engineer shall promptly deliver his/her written instructions to the Contractor, resolving all deficiencies mentioned in the reports. The Contractor shall not proceed with any Work affected by any such deficiency prior to receipt by the Contractor of said written instructions. If, during the course of the Work, any further errors, omissions, conflicts or insufficiencies in the Contract Documents shall be discovered by the Contractor or any Subcontractor, it shall be the Contractor's duty to report them promptly in writing to the Engineer and obtain his/her written instructions resolving such deficiencies before proceeding further with the Work affected thereby. If the Contractor shall proceed with any Work affected by any deficiency required to be reported pursuant to this paragraph, after the discovery thereof and prior to receipt of or without complying with the Engineer's written instructions resolving such deficiency, the Contractor shall make any and all corrections in or replacement of such Work, and shall repair all damage to other Work caused by such correction or replacement, as shall be required, in the Engineer's opinion and at his/her order, to bring the Work into compliance with the Contract Documents as amended by the Engineer's written instructions, without claim against the City for additional compensation or additional time for completion of the entire Work. Failure of the Contractor or any Subcontractor to diligently discover and report, in the manner required by this section, any deficiency in the Contract Documents affecting the Work which would necessarily have been discovered had either Contractor City of Fresno Dept. of Public Works2-6A9 May 2024
fulfilled its obligation under the contract to have carefully reviewed all of the Contract Documents prior to submitting the bid, or Contractor prosecuted the Work in the required thorough and first-class manner, shall not relieve the Contractor of responsibility. Any Work proceeded with under any deficient specification after the time when, in the exercise of the required diligence as aforesaid, such deficiency should have been discovered, the Contractor shall be liable for the correction or replacement thereof and the repair of any damage caused thereby to the same extent and subject to the same terms as for Work corrected or replaced under the subparagraph next above.The Engineer will furnish additional details where necessary to more fully explain the Work, and same shall be considered a part of the contract. Full-size details shall take precedence over scale drawings. Any Work done before receipt of such details, if not in accordance with same, shall be removed and replaced or adjusted, as directed, without expense to the City. Should any such details be, in the opinion of the Contractor, more elaborate than scale drawings and written Specifications warrant, written notice thereof shall be given to the Engineer within five Days of receipt of same. The notice will then be considered, and if justified, in the opinion of the Engineer, the details will be amended or the extra work authorized. 2-5.2 Precedence of Contract Documents If any differences or conflicts within or between the Contract Documents were not called to the City’s attention by the Contractor prior to submission of bids, interpretations will be based on the following order of precedence of documents: a) Rules and Regulations of Federal Agencies relating to the source of funds for the project b) Permits from agencies as may be required by law. c) Supplemental Agreements, Change Orders, or contract the one dated later having precedence over another dated earlier. d) Special Conditions. e) Plans, Specifications and City Standard Drawings. f) State Standard Drawings. g) Rules and Regulations of Federal Agencies relating to the source of funds for the project. Change orders, supplemental agreements and approved revisions to Plans, City Standard Drawings and Specifications will take precedence over documents listed above.
City of Fresno Dept. of Public Works2-7A9 May 2024
Whenever any conflict appears in any portions of the contract, it shall be resolved by application of the order of precedence. As indicated above, the Plans and Specifications are to be of equal priority and the City Standard Specifications and City Standard Drawings are to be of equal priority. In the event of any internal inconsistency in either the Plans, Specifications or City standard Drawings, or with each other, the appropriate method of performing the Work, in the event of the above mentioned inconsistency, shall be determined by City. Figures take precedence over physical scale measurements. Large scale details take precedence over smaller scale details. Plans take precedence in regard to dimensions, when in conflict with mechanical and structural drawings, except for the size of the structural members.Specifically titled Plans and City Standard Drawings, and specifically titled sections of the Specifications take precedence over indication of the item in a collateral way. For dimensions, existing conditions take precedence over Plans, Specifications, City Standard Drawings and State Standard Drawings. In the event of inconsistencies within any other particular Contract Document, Contractor shall (i) provide the better quality or greater quantity of Work, or (ii) comply with the more stringent requirement; either or both in accordance with the City’s interpretation. Work not covered in the Contract Documents will not be required unless it is consistent therewith and is reasonably inferable therefrom as being necessary to produce the intended results. For purpose of this provision, “reasonably inferable” shall include any change resulting in no more than non-material additional costs to the Contractor, minor submittals by the Contractor without additional design, and minor changes in sequencing and scheduling. 2-5.3 Shop Drawings When shop drawings are required by the Specifications or requested by the Engineer, they shall be prepared in accordance with modern engineering practice at the Contractor's expense. Unless otherwise specified, six copies of shop drawings shall be submitted to the Engineer for approval or correction at least 30 Days before approved drawings will be required for the Work. One set will be returned to the Contractor marked "approved" or "approved as corrected". If changes are required, 6 copies of corrected shop drawings shall be delivered to the Engineer. Shop drawings shall be of a size and scale to clearly show all necessary details. For items requiring shop drawings, no materials shall be furnished or Work done before approval of the drawings. Approval of shop drawings by the Engineer is interpreted to mean that there is substantial and acceptable conformance with the contract Plans, but details of design may not necessarily be checked for adequacy or accuracy. Such approval shall not relieve the Contractor from the responsibility for errors or omissions in the shop drawings or from deviations from the Contract Documents unless such errors, omissions, or deviations were specifically called to the attention of the Engineer. The City of Fresno Dept. of Public Works2-8A9 May 2024
Contractor shall be responsible for the correctness of the shop drawings, for shop fits and field corrections, and for the results obtained by use of such shop drawings.2-6 WORK TO BE DONEThe Contractor shall perform all Work necessary to complete the contract in a first class manner and satisfactory to City. Unless otherwise provided, the Contractor shall furnish all materials, equipment, tools, labor and incidentals necessary to complete the Work. 2-7 SUBSURFACE DATA All soil and test hole data, water table elevations, and soil analyses shown on the drawings or included in the Specifications apply only at the location of the test holes and to the depths indicated. Soil test reports for test holes which have been drilled are available for inspection at the office of the Engineer. Any additional subsurface exploration shall be done by bidders or the Contractor at their own expense.The indicated elevation of the water table is that existing at the date the test hole data was determined. It is the Contractor’s responsibility to determine and allow for the elevation of ground water at the date of performing the Work. A difference in elevation between ground water shown in soil boring logs and ground water actually encountered during construction will not be considered as a basis for extra work.See subsection 2-5.1 concerning reliance on data, tests and analyses. 2-8 RIGHT-OF-WAY Right-of-ways or easements for the improvement as shown on the Plans will be provided by the City. Unless otherwise provided, the Contractor shall make his/her own arrangements, pay for, and assume all responsibility for acquiring, using, and disposing of additional Work areas and facilities temporarily required by him/her. She/He shall indemnify and hold the City harmless from all claims for damages occasioned by such actions. The Contractor shall notify all property owners in writing along the public right-of-way 96 hours in advance of construction as to when, how, and how long they will be affected. The Letter of Notification shall also give the name of the person representing the Contractor and his/her telephone number. The letter shall be prepared and delivered by the Contractor. 2-9 SURVEYING 2-9.1 Permanent Survey Markers The Contractor shall notify the Engineer at least 7 Days before starting Work in order that the Engineer may take necessary measurements to ensure the preservation of City of Fresno Dept. of Public Works2-9A9 May 2024
permanent survey monuments and bench marks. The Contractor shall not disturb permanent survey monuments or bench marks without the consent of the Engineer, and shall bear the expense of replacing any that may be disturbed without permission. Replacement shall be done only by the Engineer. When a change is made in the finished elevation of the pavement of any Roadway in which a permanent survey monument is located, the Engineer will adjust the monument cover to the new grade unless otherwise specified. 2-9.2 Lot Stakes The Contractor shall preserve property line and corner survey markers except where their destruction is unavoidable, and the Contractor is proceeding in accordance with accepted practice. Markers that otherwise are lost or disturbed by his/her operations shall be replaced at the Contractor's expense by a registered civil engineer allowed to reset property corners or by a licensed land surveyor. 2-9.3 Survey Services Surveying adequate for construction will be done by the Engineer except for private contracts. The Contractor shall be responsible for preserving construction survey stakes and marks for the duration of their usefulness. If any construction survey stakes are lost or disturbed and need to be replaced, such replacement shall be by the Engineer at the expense of the Contractor. The Contractor shall notify the Engineer at least 2 working days before she/he will require survey services in connection with laying out of any portion of the Work. The Contractor shall dig all holes necessary for line and grade stakes. Normally, stakes will be set and stationed by the Engineer for curbs, headers, Sewers, Storm Drains, structures, and rough grade and a corresponding cut or fill to finished grade (or flow line) indicated on a grade sheet. 2-9.4 Private Engineers Surveying by private engineers on work under the control of the City shall conform to the quality and practice required by the Engineer. The Engineer shall be notified before the stakes are set. Private engineers are required to furnish cut sheets to the Engineer immediately upon the setting of the grades. 2-9.5 Line and Grade All Work upon completion shall conform to the lines, elevations and grades shown on the Plans. Three consecutive points set on the same slope shall be used together so that any variation from a straight grade can be detected. Any such variation shall be reported City of Fresno Dept. of Public Works2-10 A9 May 2024
to the Engineer. In the absence of such report, the Contractor shall be responsible for any error in the grade of the finished Work. Grades for underground conduits will be set at the surface of the ground. The Contractor shall transfer them to the bottom of the trench. 2-10 CITY SUPERVISION AND INSPECTION The Work will be done under the Supervision of the Engineer. The Engineer may specify the Work sequence to the extent necessary to obtain the best results and to protect the City's interests. The Contractor shall promptly comply with instructions from the Engineer or his/her authorized representative. The Engineer's approval of construction schedule will be given only if she/he is satisfied that the Contractor's construction schedule is sufficiently detailed to show clearly the Work to be completed during each month and, if adhered to, will be substantially sufficient to assure the completion of the Work within the time for completion set forth in the Specifications, and only if, in his/her opinion, the cost breakdown fairly apportions the Contract Price to the value of the Work and is in sufficient detail to provide a workable basis for progress payments. When the specific conditions require, the Contractor's construction schedule, in the form and content as finally approved by the Engineer, shall be incorporated in and be thereafter a part of the Specifications, and shall be the schedule on which the Work shall progress, and all progress payments shall be computed on the basis of the cost breakdown therein. The Contractor agrees to complete each monthly segment of the Work no later than the date specified in the construction schedule for completion thereof and the Contractor agrees not to deviate from said schedule without having first obtained the written approval of the Engineer. All Work and materials are subject to inspection and approval of the Engineer. The Contractor shall notify the Engineer before noon of the working day before inspection is required. Unless otherwise authorized, Work shall be done only in the presence of the Engineer or his/her authorized representatives. Any Work done without proper inspection will be subject to rejection. The Engineer and his/her authorized representatives shall at all times have access to the Work during its construction at shops and yards as well as the project Site. The Contractor shall provide every reasonable facility for ascertaining that the materials and workmanship are in accordance with these Specifications.Inspection of the Work shall not relieve the Contractor of the obligation to fulfill all conditions of the Contract.No oral or telephonic agreement or conversation with any officer, agent, or employee of the owner or the Engineer, or with the Engineer, either before or after execution of the Contract, shall affect or modify any of the terms or obligations contained in any of the Contract Documents.The Contractor shall pay the City for all overtime inspection direct costs, unless the charges for such inspection have been expressly waived in the Special Conditions.Overtime inspection charges will be made for all inspections on Saturdays, Sundays, City of Fresno Dept. of Public Works2-11 A9 May 2024
and City holidays, and hours worked by the City inspector other than those of the normal City working day. 2-11 MATERIALS ACCEPTANCE TESTINGAcceptance testing of materials provided during construction of improvements within the City right-of-way and City-owned facilities is a key activity to protect the City’s interests. The purpose of acceptance testing is to demonstrate that the materials provided by contract will perform as designed, resulting in the proper function, design life and maintainability of the various improvements that are constructed. Firms that perform acceptance testing within the City right-of-way are subject to all labor and business practices requirements which include, but are not limited to, prevailing wage requirements, OSHA standards, and workers’ compensation requirements. The following requirements are to be utilized in conducting materials acceptance testing for soils, aggregate materials and asphalt concrete. 2-11.1 Pre-Project Approval of Testing Firms Only firms with qualified personnel and well maintained equipment can be utilized to provide acceptance testing. To assist in selecting qualified firms, the City will maintain a list of qualified local firms that can be utilized. However, for smaller projects, a procedure to provide temporary approval of non-local firms to provide acceptance testing for individual projects is provided. a) Approval of Local Firms The City Public Works Department will maintain a list of qualified local firms that can be utilized by public agencies and private enterprises to provided acceptance testing. The City Public Works Department has a procedure to evaluate minimum standards for qualified personnel and supervision, testing equipment and facilities, and professional liability insurance. The Engineer reserves the right to add or remove firms based on the results of this evaluation and/or project performance. Acceptance testing provided by firms that are not included on the approved list, or are removed for poor performance, or do not meet the requirements for a temporary approval will not be allowed. Firms can apply to be included on the Approved Local Testing Firm List by contacting the Construction Management Office (559-621-5600) and submitting to the approval process. Developers and Contractors can obtain the updated list by contacting the Construction Management Office (559-621-5600). b) Single Project Temporary Acceptance City of Fresno Dept. of Public Works2-12 A9 May 2024
A procedure for Developers and Contractors to utilize non-local firms to provide testing for single projects will be provided. Methods used to evaluate the firm’s qualifications can include any or all of the following at the discretion of the Engineer:1. Reciprocity to certification programs such as AASHTO R18 or CALTRANS METS for the appropriate materials; 2. Reciprocity in a similar local agency’s testing qualification program; and 3. Adequate Statement of Qualifications submittal. 2-11.2 Pre-Construction If it is determined by the City Public Works Department that acceptance testing is required, the City Construction Management Division will require a letter from an approved testing firm stating: a) The “Firm” has been retained by “Owner” to provide acceptance testing on the “Project.” b) The firm will provide acceptance testing that meets or exceeds the minimum requirements provided in the latest edition of the City Standard Specifications; c) The firm accepts the responsibility to provide the level of service required to make the conclusion that the soils and materials used to construct the project met minimum City standards and/or improvement Plans approved by the City Public Works Department at the completion of the project; d) The letter will be required to be signed by the registered professional engineer of record responsible for the testing This letter designating the qualified firm will be required prior to approval of the Street Work permit by the Engineer. 2-11.3 Execution of Acceptance Testing The Developer/Owner, or designated representative, will coordinate testing services, verify that testing is being conducted, respond to remedy sub-standard materials test results, and provide payment for testing services. The approved testing firm will provide qualified personnel to conduct tests, maintained accurate materials testing equipment, and provide prompt test results to the Developer/Owner, Contractor, and City representatives. The following sections describe the scope of acceptance testing required, the minimum frequency of tests, and the methods approved for use. The following sections provide the approved test methods and the minimum frequency of tests.

One test per 500 feet must be in the pipe zone bedding. One test per 24 inches of depth must be provided for trenches shorter than 150 feet. In the upper 2 feet, at least one test per 50 lineal feet shall be conducted. Where multiple Sewer laterals are installed, a minimum of one in-place density test every two laterals shall be taken between the main and the right-of-way boundary. Also, for manhole backfill, at least one in-place density test per 24 inches of depth shall be taken (i.e. for 7 foot deep manhole, 14 tests will be required). Moisture/Density relationship curves shall be conducted for each different material encountered. A minimum of one check point test per 1,000 lineal feet of Roadway shall be conducted to verify that materials are consistent, or as needed if soil conditions change. As-Graded R-Value Tests City of Fresno Dept. of Public Works2-14 A9 May 2024
Prior to fine grading for pavement subgrade and after all underground Utilities are installed, R-values shall be collected from the materials representative of the fine graded condition. These tests are required to be conducted to verify that the subgrade solid are consistent with the design R-value used for pavement thickness reported on the Plans. R-Value samples representative of the subgrade materials shall be collected at a rate of one test per 100,000 square feet of planned pavement, two tests minimum for 50,000 to 100,000 square feet of pavement, and one test for planned pavement areas less than 50,000 square feet. An R-value sample shall be collected at each location where a residential Street intersects a Collector or Arterial. The locations of the R-value must be approved by a City Construction Management Division representative prior to collecting samples and conducting the tests. The R-value results shall be reported to the City Construction Management Division including a map noting sample locations, comparison to the design R-value, and conclusions about the adequacy of the design R-value based on the results. If any R-value result is less than that used for the design, the pavement subgrade elevation and AB section thickness shall be adjusted based on the actual subgrade R-value results in accordance with the flexible pavement design procedure provided in Chapter 600 of the CALTRANS Highway Design Manual. Subgrade for Pavement, Curb/Gutter and Sidewalk The minimum frequency of in-place density tests for subgrade soils are as follows: Curb and Gutter: One 6-inch deep in-place density test per 250 lineal feet Sidewalk: One 6-inch deep in-place density test per 250 lineal feet Pavement: One 6-inch deep in-place density test per 250 lineal feet per 12 foot wide lane (includes park lanes) Moisture/Density relationship curves shall be conducted for each different material encountered.

SECTION 3–CHANGES IN WORK3-1 CHANGES REQUESTED BY THE CONTRACTOR Changes in methods of construction previously proposed and accepted by City, or contained in the Specifications, may be made at the Contractor's request upon written approval of the Engineer.Changes in the Plans and Specifications, requested in writing by the Contractor, which do not materially affect the Work and which are not detrimental to the Work or to the interests of the City, may be granted to facilitate the Work, when approved in writing by the Engineer. Contractor’s request shall include a detail of any cost savings anticipated by the requested change. 3-1.1 Payment for Changes Requested by the Contractor If such changes are granted, they shall be made at a reduction in cost, or at no additional cost to the City, as determined by the City. Nothing herein shall be construed as granting a right to the Contractor to demand acceptance of such changes. 3-2 CHANGES INITIATED BY THE CITY At any time during the progress of the Work, and without in any way rendering void the Contract, the City may order alterations in and additions to or deductions from, the Work, and, when so ordered in writing, the Contractor shall proceed with the changes directed in such order. The Contractor shall not be entitled to any extension of time for the completion of the Work by virtue of any change order unless, with respect to a change order executed by the Contractor, the change order specifically provides therefor, or, with respect to a change order not so executed, the Contractor, within five Days after receipt of the order, files a written claim therefor with the Engineer, in which event she/he shall be entitled to a reasonable extension of time as determined by the Engineer. 3-2.1 Payment for Changes Initiated by the City 3-2.1.1 Agreed Prices The Contractor and the City may agree upon Contract Unit Prices or lump sums which shall be used to increase or decrease the Contract Price on account of any change ordered. In the absence of any such agreement the Contract Price shall be adjusted as hereinafter provided.
City of Fresno Dept. of Public Works3-2A9 May 2024
3-2.1.2 Unit PricesWhenever an item of Work or materials is specified in the contract by a Contract Unit Price and is changed by not more than twenty-five percent of the Engineer's estimate as contained in the Specifications, then the Contract Price shall be increased or decreased by the application of the Contract Unit Price so specified.Contract Unit Prices shall govern not only for alterations in, and additions to or deductions from, the Work in connection with the structures and installations covered by the written Specifications and drawings, but also for other Work incidental or necessary to the use of such structures and installations for which written Specifications and drawings may be later prepared. Whenever said change exceeds said twenty-five percent, the addition or subtraction from the Contract Price shall be established under subsection 3-2.1.3. 3-2.1.3 Formula for Prices With respect to each change ordered for which no adjustment in Contract Price has been agreed upon, and for which Contract Unit Prices are not applicable, the Contractor shall keep, and submit to the Engineer at such intervals as the Engineer may direct, an accurate and complete account and record, certified and verified in such manner as the Engineer shall direct, of each of the following to the extent that they are directly the result of the change ordered: a) The actual cost of all direct labor performed (including the pro-rata cost of foremen continuously employed on the Work, but not the salary, or any part thereof, of the Contractor's superintendent), and all materials and equipment furnished and incorporated in the Work, less all available cash, trade, and other discounts. b) The actual cost of rental for the use of such items of equipment as have an individual value in excess of three hundred dollars, provided that the use of such equipment and the rental rate therefor, shall first have been authorized and approved by the City in writing. c) The actual cost of all royalties and permit fees. In determining the net increase or decrease in the Contract Price as the result of the change ordered, the Engineer shall compute the total amount, if any, of the actual costs specified in (1), (2), and (3) above to the extent that they are accurately reflected in the account and record of the Contractor, and the Engineer shall estimate the amount, if any, by which any change ordered would result in a decrease in any of the items of cost specified in (1) , (2) , and (3) above, and to the net difference between these two amounts she/he shall add a sum equal to twenty per cent thereof for all overhead and profit. If the net amount so determined represents an addition in cost, it shall be added to the Contract Price, and if it represents a decrease in cost, it shall be deducted therefrom, and, in either case, City of Fresno Dept. of Public Works3-3A9 May 2024
it shall constitute compensation in full for the addition or full settlement of the amount to be deducted, as the case may be, for the change ordered.3-2.1.4 Limited City PowerThe Contractor recognizes that the City is a public agency and that it can act only through its duly authorized agents, and in this regard agrees that only written change orders, executed as specifically authorized by the Council, shall be valid.The Engineer shall have no authority to issue a change order unless so specifically authorized, and no person shall have authority to issue any oral change order. Unless a valid change order is issued therefor, all changes in the Work performed by the Contractor shall be at his/her own risk, and she/he shall not be entitled to any additional compensation on account thereof, and she/he may be required to make the Work conform to the Plans and Specifications. No act or series of acts by the City during the course of the contract shall be deemed to constitute a waiver of the right of the City to rely upon the provisions of this subparagraph. 3-2.1.5 Changes in Accordance with Specifications Each change ordered shall be performed in accordance with the Plans and Specifications insofar as they may be applied without conflict with the conditions set forth in the change order. 3-3 EXTRA WORK 3-3.1 General New or unforeseen work will be classed as "extra work" when the Engineer determines that it is not covered by lump sums, Contract Unit Prices or stipulated unit prices and the character of such work is substantially different from that on which the Contractor bid. Should the Contractor encounter conditions materially different from those indicated by the Plans and Specifications, or materially different from conditions generally recognized as inherent in the kind of Work being performed, she/he shall immediately notify the Engineer, who will promptly investigate. If conditions do materially differ in a way that the Contractor could not reasonably have foreseen and cause a decrease or increase in the Contractor's cost of, or the time required for, performance of any part of the Work, a change order will be issued for an appropriate adjustment in contract time and cost pursuant to this section; but the Contractor is not relieved of his/her responsibility to foresee such conditions as may be discovered by a reasonable examination of the Site or materials available regarding the Site or the Work, including performance of due diligence as required in subsection 2-5.1 and subsection 7-15 of these City Standard Specifications.

4-1.6 Compaction Tests Relative compaction of soil in trenches, embankment or structural backfill shall be determined by the laboratory standard of test procedure ASTM D1557. To be considered a “passing” test, compaction tests shall meet the required relative percent compaction and indicate moisture content within 2% of optimum. The moisture content within 2% of optimum is generally required, but in some instances may be considered a goal. In some instances, 2% moisture cannot be achieved; however, the Contractor shall try to get as close to 2% moisture as possible. Drive-tube sampling of compacted soil may be utilized, unless otherwise directed by the Engineer. For projects where the City is responsible for coordinating materials acceptance testing by contract, the Contractor shall give notice to the Engineer 2 working days in advance of when the required compaction tests are to be taken.The initial compaction tests will be taken at the expense of the City.

6-2 PROSECUTION OF WORKTo minimize public inconvenience and possible hazard and to restore Streets and other Work areas to their original condition and former state of usefulness as soon as practicable, the Contractor shall diligently prosecute the Work to completion. If in the Engineer's opinion the Contractor fails to prosecute the Work to the extent that the above purposes are not being accomplished, the Contractor shall, upon orders from the Engineer, immediately take the steps necessary to fully accomplish said purposes. All costs of prosecuting the Work as described herein shall be absorbed in the Contractor's bid. Should the Contractor fail to take the necessary steps to fully accomplish said purposes after orders of the Engineer to do so, the Engineer may suspend the Work in whole or in part until the Contractor takes said steps. With or without such suspension, the Engineer may cause such steps to be taken by force account or other means at the Contractor's expense. As soon as possible under the provisions of these City Standard Specifications, the Contractor shall backfill all excavations and restore, to usefulness, all improvements existing prior to the start of the Work. The Engineer may require open excavations to be fenced if in his/her judgment the situation presents a potential hazard to the public. If Work is suspended through no fault of the City, all expenses and losses incurred by the Contractor during such suspensions shall be borne by him/her. If the Contractor fails to properly provide for public safety, traffic, and protection of the Work during periods of suspension, the City may elect to do so, and deduct the cost thereof from monies due the Contractor. Such action will not relieve the Contractor from any liability. 6-3 SUSPENSION OF WORK The Work may be suspended in whole or in part, when in the Engineer's opinion the suspension is necessary in the interest of the City. The Contractor shall comply immediately with any written order of the Engineer suspending Work. Such suspension shall be without liability to the Contractor on the part of the City.

If the Contractor is in default, the City may give written Notice to the Contractor that if said default or defaults as specified in said Notice are not remedied within a specified time (which shall be not less than five Days from receipt of said Notice), the Contractor's control over the Work will be terminated. If any such default specified in said Notice is not remedied to the satisfaction of the City and the Engineer within the time specified in said Notice, the City may give the Contractor and Surety written Notice of termination, and on the date specified in such Notice the Contractor's control over the Work shall terminate. Upon such termination, the City may enter upon and take possession of the entire Work and may also take possession, for the purpose of completing the Work, of all of the Contractor's tools, equipment and appliances upon the Work, and all materials on the Site or stored off-Site for incorporation into the Work; and the City may thereupon call upon and permit the Surety on any performance bond given to guarantee the performance of the contract to take over and complete the Work under the Contract, or the City may, at its sole option and without further Notice to anyone, take over and complete the Work by day labor or by contract entered into by negotiation or by competitive bidding or otherwise, as the City in its sole discretion shall elect.After termination of the Contractor's control over the Work as herein provided, the Contractor shall not be entitled to any further payments under the contract until the entire Work thereunder has been fully completed and finally accepted by the City. After such completion and acceptance, if the unpaid balance of the Contract Price (as defined in the next paragraph) exceeds the sum of the amounts expended by the City in taking over and completing the Work (including, without limitation, all managerial and administrative expenses incurred by the City on account thereof) and the amount of all damages incurred by the City by reason of the Contractor's default, such excess shall be paid to the Contractor. However, if said sum exceeds said unpaid balance, the Contractor and his/her Surety shall be liable to the City for the difference. The expense incurred by the City in taking over and completing the Work, and the amount of any damage incurred by the City by reason of the Contractor's default shall be audited and certified by the Engineer, whose certificate thereof shall be binding and conclusive upon the parties.For the purposes of the computations required by the paragraph above, the "unpaid balance of the Contract Price" shall be the original Contract Price as adjusted by any change orders issued prior to termination of the Contractor's control, less all payments made on account thereof prior to such termination, less all amounts withheld for liquidated damages or disputed work or claims prior to termination of Contractor’s control, and less any and all amounts withheld or paid pursuant to stop notice-filed with the City upon claims of Subcontractors or others for equipment, labor or materials furnished to the Work by order of or contract with the Contractor. Upon completion and acceptance of the Work, the Contractor shall be entitled to the return of all his/her materials not used in the Work, but without claim against the City for loss or damage with respect thereto, and shall be entitled to the return of all his/her equipment, tools and appliances taken possession of by the City, but without claim against the City for any charge for the use thereof or for usual and ordinary depreciation and wear and tear.
City of Fresno Dept. of Public Works6-4A9 May 2024
The remedies provided in this paragraph for default of the Contractor shall be in addition to, and the exercise thereof shall not be deemed a waiver by the City of, any other rights and remedies of the City under the contract or afforded by law for default of the Contractor. 6-5 CONTRACTOR’S RIGHT TO STOP WORK OR TERMINATE CONTRACT If City fails to pay Contractor within 30 days after its due date any amounts covered by an application for payment, the payment of which is disputed by City, City or Contractor may, upon 7 Days written notice to the other, commence dispute resolution proceedings in accordance with the terms of the Contract Documents. In the event City disputes any payments due under the Contract Documents, Contractor shall not be entitled to suspend the Work or terminate the contract but must continue the performance of its services and the Work in accordance with the construction schedule therefor under the Contract Documents during the period during which the dispute is being resolved, provided Contractor is being promptly paid for all undisputed amounts. If the dispute is resolved in Contractor's favor and City fails to pay Contractor the amount determined to be owed to Contractor pursuant to mediation, if applicable, within 30 days thereafter, Contractor shall be entitled to suspend the Work or terminate this contract as long as such failure continues and in accordance with the provisions contained herein. The Contractor may give written notice to the Engineer and the City of intention to stop Work or terminate the contract, or both, unless payment is received within ten Days from receipt of such notice. If, after the expiration of said time the payment is not received, the Contractor may stop Work and may give written notice of termination of the contract to the City. The Contractor may also recover from the City payment for all Work executed and any loss sustained upon any equipment or materials procured for the Work prior to the Work stoppage, but such right to recovery shall be subject, however, to the duty of the Contractor to mitigate all loss or damage so far as reasonably possible. 6-6 TERMINATION OF CONTRACT The Council may, at any time, terminate the contract for the City's convenience and without cause. The Council shall have the right to terminate this contract without cause at any time by giving to Contractor 72 hours written notice thereof. Upon receipt of such notice, Contractor immediately shall terminate performance of the Work and make reasonable efforts to mitigate its losses and damages hereunder; provided, however that in connection with such termination, Contractor shall perform such acts as may be necessary to preserve and protect that part of the Work theretofore performed hereunder.

City of Fresno Dept. of Public Works6-5A9 May 2024
a) cease operation as specified in the notice;b) place no further orders and enter into no further subcontracts for materials, labor, services or facilities except as otherwise specified in writing by City; c) terminate all subcontracts and purchase orders to the extent that City does not elect to assume such subcontracts and purchase orders; and d) take actions that may be necessary, or that City may direct in writing, for the protection and preservation of the Work. In addition to payment for the Work performed prior to the effective date of termination and for any work performed following the date of termination pursuant to City's written request, Contractor shall be entitled to payment for materials timely fabricated off the Site and delivered and stored in accordance with the City's instructions.Upon such termination without cause, Contractor shall retain all sums of money theretofore paid hereunder to Contractor and provided: a) that no liens or claims have been filed of record with respect to Work performed hereunder or that all such liens and claims have been satisfied in the manner provided in the Contract Documents and provided further that Contractor has been paid by City for the Work which is the subject of the lien(s) or claim(s) if required to be paid therefore pursuant to the Contract Documents, and b) that Contractor delivers to City: 1. Contractor's unconditional waiver and release of claims with respect to the Work performed through the date of termination and paid for by City, 2. Subcontractor and supplier unconditional waiver and release of claims for all subcontracts and supply agreements that have been fully performed on the date of termination, and 3. an assignment to City or to the replacement contractor or City's designee of all subcontracts and purchase orders which City elects to assume by written notice to Contractor, City shall pay to Contractor (i) all retainages, if any, theretofore retained hereunder by City in respect of the Work properly performed to the date of such termination (other than the retainage relating to portions of the Work performed by Subcontractors whose subcontracts City assumes, which retained amounts under such subcontracts will continue to be paid at the time and in the manner specified in the Contract Documents, (ii) payment for the Work properly executed in accordance with the Contract Documents prior to the effective date of termination (the basis for such payment shall be as provided in the Contract Documents), (iii) for the direct costs incurred by Contractor in terminating the Work, including out-of-pocket costs incurred by Contractor to third parties for City of Fresno Dept. of Public Works6-6A9 May 2024
cancelling subcontracts and purchase orders as a result of the termination of this contract authorized in accordance with the provision of this section, and (iv) reasonable demobilization costs, but City shall not otherwise be responsible for damages for lost or anticipated fees and/or profits on Work not performed on account of any termination described in this contract.City shall not be obligated to reimburse Contractor for any central office overhead in connection with the termination. However, in no event shall the amounts to be paid to Contractor pursuant to the preceding paragraph, when combined with the amounts previously paid to Contractor and the costs thereafter required to be paid by City to complete the Work, exceed the Contract Price. The amounts owing by City to Contractor pursuant to the two immediately preceding sentences shall be as specified in Contractor's final application for payment approved by City. If City terminates without cause, then City (or a replacement contractor or another designee of City), shall, with respect to all subcontracts and purchase orders which City does not elect to terminate (or cause Contractor to terminate) assume the obligations of Contractor under such subcontracts and purchase orders covering the unperformed parts of the Work and properly entered into in accordance with the contract. Contractor shall also, upon request, deliver and assign to City or City's designee any and all subcontracts, purchase orders, options and other contracts made by Contractor in performance of the Work, and deliver to City true and correct originals and all copies of the Contract Documents, and of all other materials relating to the Work which belongs to City, together with all papers and documents relating to governmental permits, orders placed, bills and invoices, lien releases, waiver and release of claims, and financial management under the Contract Documents. Notwithstanding any termination, Contractor shall take such steps as are reasonably necessary to preserve and protect the Work completed and in progress and to protect materials, supplies, plant and equipment at the Site or in transit. No action taken by City shall prejudice any other rights or remedies of City provided by law or by the contract.However, Contractor shall remain liable under the warranty provided in the Contract Documents with respect to all of the Work performed by Contractor prior to termination. 6-7 DELAYS AND EXTENSION OF TIME By executing the contract, the Contractor confirms that the contract time (the period between the date thereof and the schedule date of substantial completion as set forth in the Contract Documents) is a reasonable period for performing the Work. The Contractor shall proceed expeditiously with adequate forces and shall achieve substantial completion of the Work within the contract time. The Contractor covenants and agrees to use its best and diligent efforts to avoid the occurrence of any cause for delay and to avoid any extensions of performance dates except force majeure delays. Contractor shall notify the City and the Engineer of any cessation of the Work and total amount of delay, if any, in performance dates which City of Fresno Dept. of Public Works6-7A9 May 2024
Contractor claims by reason of any such occurrence. Immediately following the commencement of such cause for delay, representatives of the Contractor, City and Engineer shall confer for the purpose of endeavoring to determine a course of action which would terminate or eliminate the occurrence or event which is causing delay.Failure of Contractor to timely assert any alleged claim for extension shall constitute a waiver of the particular claim. Notwithstanding anything to the contrary in the foregoing, the Contractor shall not be entitled to an extension of time unless the event or circumstances giving rise to a delay constitutes a Force Majeure Event and the activity delayed will result in a delay of the scheduled date for substantial completion of the project. "Force Majeure Event" means only: (i) strikes, lockouts or picketing (legal or illegal) which are not limited to the Site or projects which only the Contractor or any of its Subcontractors are involved with; (ii) governmental action (other than by City in its contracting capacity) and condemnation; (iii) riot, civil commotion, insurrection, and war; (iv) fire or other casualty, accident, acts of God or the enemy; (v) unusually adverse weather conditions to be reasonably expected for the location of the Project and the time of the year in question (substantiated as provided in this section below; (vi) unavailability of fuel, power, supplies or materials (and unavailability of any reasonable, if at the same price, practicable alternatives); (vii) the passage of, or the reasonably unexpected interpretation or application of, any statute, law, regulation or moratorium of any governmental authority; (viii) other causes beyond the reasonable control of Contractor (except to the extent in conflict with the above); or (ix) delays caused by the act or omission of the City or any separate contractor retained by City (if any), by delay authorized by the City, or resulting from changes in the Work (but only as set forth on the Change Orders therefor); provided, however, that neither the acts or omissions of Contractor, Subcontractors or suppliers, nor the Contractor's or any Subcontractor's insufficiency of funds, bankruptcy or insolvency, shall be deemed a Force Majeure Event. If the Contractor wishes to make a claim for an increase in the contract time, written notice shall be given within 10 Days of Contractor’s discovery of the Force Majeure Event giving rise to such claim and at least 15 Days before the specified completion date. The Contractor's claim shall include an estimate of cost and of probable effect of delay on progress of the Work. In the case of a continuing delay, only one claim is necessary. If adverse weather conditions are the basis for a claim for additional time, such claim shall be documented by data substantiating that weather conditions were abnormal for the period of time, could not have been reasonably anticipated and had an adverse effect on the scheduled construction, provided that the weather impact is beyond normal expectancy for the month in which the occurrence takes place based on historical weather data. The City shall own the float associated with weather delays. Except for the Contractor's right to terminate this contract pursuant to the provisions of subsection 6-5 above, the Contractor's sole remedy for any delay by the City or its agents or employees shall be an extension or extensions of time as set forth in this section, unless the same shall have been caused by acts or omissions of the City that interfere with the Contractor's performance of the Work. The City's exercise of any of its rights or remedies to suspend the Work or to require correction or re-execution of any defective City of Fresno Dept. of Public Works6-8A9 May 2024
Work, shall not under any circumstances be construed as acts interfering with the Contractor's performance of the Work. With respect to City caused delay, Contractor shall be entitled to recover additional actual direct costs for any such delays, if such delays and costs result from the acts or omissions of the City or its consultants, separate contractors or representatives or changes in the Work provided that the delays impact the critical path of the project schedule. The increase in the Contract Price resulting from such delays shall be limited to the increase, if any, of actual direct costs incurred by the Contractor in performing the Work as a result of any such delays which cause the contract time to be increased. For purposes of this section, such direct costs are the reasonable increased costs of Contractor incurred for labor, materials, supplies and equipment, rental costs and machinery and equipment, subcontract costs, additional costs of supervision and field office personnel directly attributable to such increased costs, but excluding any profit or fee.Any extensions of time, when granted, will be based upon the effect of delays to the project as a whole and will not be granted for non-controlling delays to included portions of the Work unless it can be shown that such delays did, or will in fact, delay the progress of the project as a whole.The Engineer will ascertain the facts, the extent of the delays, and the effect upon the entire project, and the City will grant an extension of time equivalent to verified time lost.Extensions in the contract time shall be granted by City only to the extent that such delay:(1) affects the critical path of the Work, (2) has not been caused by Contractor, (3) is grounds for an extension in the contract time under the Contract Documents, and (4) is of a duration not less than one (1) day. Claims by Contractor for an extension of the contract time must be made in writing to City within 10 Days after Contractor discovers the event giving rise to such claim; otherwise, Contractor will be deemed to have waived its right to claim an extension in the contract time as a result of the occurrence of such event. 6-8 TIME OF COMPLETION The Contractor shall complete the Work within the number of Days or working days set forth in the contract. A working day is defined as any Day, except Saturdays, Sundays and legal holidays and Days on which the Contractor is specifically required by the Specifications to suspend construction operations and except 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 such 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 in the morning of any Day on which inclement weather, or the conditions resulting from the weather, or City of Fresno Dept. of Public Works6-9A9 May 2024
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 currentcontrolling 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 said day and the major portion of the day could be considered to be suitable for such construction operations.6-9 PROJECT CLOSE-OUT; COMPLETION AND ACCEPTANCE When Contractor considers the Work ready for its intended use, the Contractor shall notify the City in writing that the Work is substantially complete. The Contractor shall attach to this request a list of all work items that remain to be completed and a request that the City prepare a Certificate of Substantial Completion. Within a reasonable time thereafter, the City and Contractor shall inspect the Work to determine the status of completion and to the extent that City agrees the Project is substantially complete. If the City does not consider the Work substantially complete, the City will notify Contractor in writing of the reasons therefore and Contractor shall promptly correct all items identified by the City. The City and Contractor shall repeat the above-referenced procedure until all items are completed to the City’s satisfaction, whereupon City shall issue a Certificate of Substantial Completion. On the date that the City issues the Certificate of Substantial Completion, the City shall provide Contractor with the final punch list identifying the remaining minor corrective items to be completed for final completion of the Project. When the Contractor considers the final punch list work to be complete, it shall request City to perform a final walk through of the Project to determine if said punch list work is complete and whether Contractor has otherwise completed all of its obligations under the Contract Documents. The City shall record the Notice of Final Acceptance when the entire Work including, but not limited to Contractor’s closeout document obligations are fully satisfied, Contractor’s punch list(s) and work shall have been completed to the satisfaction of the City. However, the City, at its sole option, may accept completion of the Contract and have the Notice of Final Acceptance recorded when the entire Work including individual portions of the Work shall have been completed to the satisfaction of the City, except for minor corrective items, as distinguished from incomplete items.Regardless of the cause therefore, the Contractor may not maintain any claim or cause of action against the City for damages incurred as a result of its failure or inability to complete its Work on the Project in a shorter period than established in the Contract Documents, the parties stipulating that the period set forth in the Contract Documents is a reasonable time within which to perform the work on the Project.
City of Fresno Dept. of Public Works6-10 A9 May 2024
6-10 LIQUIDATED DAMAGESTime of performance is of the essence of the Contract Documents and all obligations thereunder. The Contractor acknowledges and recognizes that the City is entitled to full and beneficial occupancy and use of the Project on the substantial completion date. If the Contractor is behind schedule to such an extent that the Contractor will be unable to meet such completion date set forth in the Bidding Requirements, as such date may be extended pursuant to the terms of this contract, the Contractor shall employ such additional forces, obtain such additional equipment, employ such additional supervision and pay such additional overtime wages as may be required to place the progress of the Work on schedule, as required for timely substantial completion. Substantial completion of the Project in accordance with the construction schedule shall not be achieved until issuance of a temporary certificate of occupancy or final certificate of occupancy, as applicable, by the applicable governmental agencies permitting occupancy of the Project. City and the Contractor, by executing the contract, each agrees that damages to the City, and damages for the inconvenience and loss which will flow to the inhabitants of the City, from any delay (other than that caused by the failure of a Utility owner to remove or relocate a Utility facility) in completion beyond the date or dates provided in the contract for the substantial completion of the Work, or portions thereof, are extremely difficult or impossible to determine, and, accordingly, it is agreed that if the Contractor fails to achieve substantial completion of the Project in accordance with the construction schedule (also referred to herein as the "contract time" and shall reflect the completion date contained in the Bidding Requirements), subject to adjustments of the contract time as provided in the Contract Documents, the City shall be entitled to retain or recover from the Contractor, as liquidated damages and not as a penalty, the per diem amounts (contained in the Bidding Requirements) commencing upon the first Day following expiration of the contract time for Substantial Completion of the Project and continuing until the actual date of substantial completion of the Project. Such liquidated damages are hereby agreed to be a manifestly reasonable amount of damages the City will incur as a result of delayed completion of the Work. The Contractor shall not be assessed liquidated damages for delay in completion of the Work or project, when such delay is caused solely by the failure of a Utility owner to provide for the removal or relocation of existing Utility facilities when the existence of such Utility facilities substantially prevents or hinders completion of the project or Work. The City shall initially process any liquidated damage claims through the Change Order process. If, however, City and Contractor have not agreed upon a deductive Change Order with respect to a liquidated damages claim within 15 Days following City's delivery of the proposed Change Order to Contractor, then City may deduct the liquidated damages from any unpaid amounts then or thereafter due the Contractor under this contract. Any liquidated damages not so deducted from any unpaid amounts due the Contractor shall be payable to the City at the demand of the City, together with interest from the date of the demand.
City of Fresno Dept. of Public Works6-11 A9 May 2024
6-11 USE OF IMPROVEMENT DURING CONSTRUCTIONThe City reserves the right to take over and utilize all or part of any completed facility or appurtenance. Such occupancy or use shall not constitute an acceptance of any part of the Work, unless so stated in writing by the City. However, such action by the City will relieve the Contractor of responsibility for injury or damage to said completed portions of the improvement resulting from use by City, use by public traffic, from the action of the elements or from any other cause, except injury or damage resulting from the Contractor's operations or negligence. The Contractor will not be required to re-clean such portions of the improvement before acceptance, except for cleanup made necessary by his/her operations. Nothing in this section shall be construed as relieving the Contractor from full responsibility for correcting defective Work or materials.

The Engineer will make the sole determination of what is safe and reasonable.
City of Fresno Dept. of Public Works7-22 A9 May 2024
The Contractor's failure to provide safe and reasonable pedestrian and vehicular access shall provide just reason to issue a stop work order to the Contractor with no additional working days added to the contract.The Contractor's operations shall cause no unnecessary inconvenience. The access rights of the public shall be considered at all times. Unless otherwise authorized, traffic shall be permitted to pass through the Work, or a detour approved by the Engineer shall be provided.

The Contractor shall cooperate with the various parties involved in the delivery of mail and the collection and removal of trash and garbage to maintain existing schedules for these services. The Contractor shall absorb in his/her bid all costs for the above requirements. 7-10.2 Americans with Disabilities Act Accessibility City of Fresno Dept. of Public Works7-23 A9 May 2024
If the previous pedestrian facility was accessible to pedestrians with disabilities, the path provided during construction and/or temporary traffic control shall also be accessible. This will consist of a continuous, unobstructed 48” wide pedestrian path of travel adjacent to the Site, preferably parallel to the same sidewalk that has been obstructed. There shall not be any abrupt changes in grade or terrain that could cause a tripping hazard or could be a barrier to wheelchair use. The Contractor shall install and maintain temporary concrete, asphalt or wood ramps to provide a safe path of travel for pedestrians at locations where ramps have been temporarily removed or are needed to route pedestrians. When it is determined that a facility should be accessible to and detectable by pedestrians with visual disabilities, a continuously detectable edging should be provided throughout the length of the facility such that it can be followed by pedestrians using long canes for guidance. These considerations include, but are not limited to, the following: a) The path of travel shall not have abrupt changes in grade, elevation, or terrain. The path of travel shall have a cross slope of 2% or less; running slope may be equal to that of the topography of the adjacent street. b) Any changes in level in a path of travel shall be ½” maximum. Changes in level that are between ¼” and ½” shall be beveled at a 45 degree angle to provide a smooth transition. c) Temporary ramps shall be a minimum of 48” wide, with a running slope ratio not to exceed 1:12 (one foot run for every inch of the curb). Sides of a ramp shall be protected where there is a drop off. For all ramps not meeting the definition of a “curb ramp”, handrails will be provided in conformance with Title 24 and the 2010 Americans with Disabilities Act Standards. d) For walkways in the pedestrian path that have less than 5’ of clear width, there shall be provided passing spaces 5’ wide every 200 ft. to provide adequate space for two pedestrians in wheelchairs to pass each other. e) Signposts, scaffolding and fencing and other supports shall be placed to provide an unobstructed path of travel that is 48” wide and 80” high. f) Closed trenches, temporary paving surfaces, walking surfaces, steel plates, etc. shall have a firm, slip-resistant walking surface made even with surrounding walkways. If plywood is used as a temporary walking surface, it will be a minimum of ¾” in thickness and it will be anchored using either a mechanical fastener, cold mix or asphalt so that it is stable and level with surrounding surfaces. g) When a sidewalk is closed and pedestrian traffic detoured, sidewalk signs indicating that the sidewalk, curb ramp, or both the sidewalk and curb ramp are closed are required. These signs shall be placed so as to provide ample City of Fresno Dept. of Public Works7-24 A9 May 2024
warning of the detour to people with mobility disabilities and minimize backtracking. Signs shall be placed so that they are visible from the sidewalk before the detour begins. All pedestrian signage mounted on barricades shall include warning lights for night visibility. h) When a sidewalk is completely closed, a barrier that is detectable by a person with a visual disability traveling with the aid of a long cane shall be placed across the full width of the closed sidewalk.i) During detours, access shall be provided by directing all pedestrian traffic to the unaltered side of the street where marked crossings and usable curb ramps exist; if such elements do not exist, temporary marked crosswalks and temporary ramps shall be provided. Any plan proposing temporary marked crosswalks and ramps shall be approved in writing by the Traffic Engineer or his/her designee. j) The continuous detectable edging shall: 1. Protrude at least 6 inches above the surface of the sidewalk or pathway, with the bottom of the edging a maximum of 2.0 inches above the surface; 2. Be continuous throughout the length of the facility except for gaps at locations where pedestrians or vehicles will be turning or crossing; 3. Consistent of a prefabricated or formed-in-place curbing or other continuous device that is placed along the edge of the sidewalk or walkway; 4. Be firmly attached to the ground or to other devices; and 5. Be orange, white, or yellow and should match the color of the adjacent channelizing devices or traffic control devices, if any are present. k) Adjacent sections of detectable edging shall be interconnected such that the edging is not displaced by pedestrian or vehicular traffic or work operations, and such that it does not constitute a hazard to pedestrians, workers, or other road users. l) If prefabricated edging is used to separate pedestrians and vehicular traffic, such edging should be certified as crashworthy. m) If section of lumber is used to form a railing system, any part of the railing that is more than 3 feet above pavement should be treated lumber and cause no harm to bare hand touching it. n) Examples of detectable edging for pedestrians include:
City of Fresno Dept. of Public Works7-25 A9 May 2024
1. Prefabricated lightweight sections of plastic, metal, or other suitable materials that are interconnected and fixed in place to form a continuous edge;2. Prefabricated lightweight sections of plastic, metal, or other suitable materials that are interconnected, fixed in place, and placed at ground level to provide a continuous connection between channelizing devices located at intervals along the edge of the sidewalk or walkway; 3. Sections of lumber interconnected and fixed in place to form a continuous edge;4. Formed-in-place asphalt or concrete curb; 5. Prefabricated concrete curb sections that are interconnected and fixed n place to form a continuous edge; 6. Continuous temporary traffic barrier or longitudinal channelizing barricades placed along the edge of the sidewalk or walkway that provides a pedestrian edging at ground level; and 7. Chain link or other fencing equipped with a continuous bottom rail. o) Fencing should not create sight distance restrictions for road users. Fences should not be constructed of materials that would be hazardous if impacted by vehicles. Wooden railing, fencing, and similar systems placed immediately adjacent to motor vehicle traffic should not be used as substitutes for crashworthy temporary traffic barriers. Ballast for TTC devices should be kept to the minimum amount needed and should be mounted low to prevent penetration of the vehicle windshield. Movement by work vehicles and equipment across designated pedestrian paths should be minimized and, when necessary, should be controlled by flaggers or TTC. Staging or stopping of work vehicles or equipment along the side of pedestrian paths should be avoided, since it encourages movement of workers, equipment, and materials across the pedestrian path. Access to the work space by workers and equipment across pedestrian walkways should be minimized because the access often creates unacceptable changes in grade, and rough or muddy terrain, and pedestrians will tend to avoid these areas by attempting non-intersection crossing where no curb ramps are available. p) The bottom 3” of fencing material (e.g. chain link, plastic, etc.) shall be solid to provide a guide for pedestrians with visual disabilities and limit the likelihood that a long cane will be caught in the fence. This may be achieved by attaching a solid material to the bottom portion of the fence.
City of Fresno Dept. of Public Works7-26 A9 May 2024

House branches shall be constructed at locations shown on the Plans or as may be directed by the Engineer and shall extend from the outlet of the "Y" or “T” branch at the Sewer main to the right-of-way line of the Street or alley, where the house branch shall be promptly closed at the bell end with a plug manufactured for that purpose. The slope and general arrangements of the house branches shall be as shown on the Plans. Plugs used to seal the ends of house branches shall be of a type approved by the manufacturer of the pipe. Excavations for laying house branches shall be made in such a manner that at no time will the Street be closed to traffic. Whenever house branches are to be installed in major Streets that have been resurfaced within the last five (5) years, or in pavement that is in good condition and free of cracking, they shall be installed by boring methods rather than open cuts trenches. Where curb and gutter exists, or is to be constructed concurrently with Sewer facilities, the location of each Sewer service shall be permanently indicated by inscribing the letter "S" two inches (2") in height in the curb directly above the line when the service is perpendicular to the Street centerline. Otherwise, the "S" mark for skewed or angling services shall be placed at a right angle to the end of the service. When Sewer services are installed in an existing Street, the curb mark shall be placed at the time the service is installed to assure proper location. In cases where a concrete curb does not exist, the Contractor shall mark the location of the terminus of the house branch by driving a one-half inch (1/2") iron pipe or rod in the end of the trench before backfilling. The pipe or rod shall extend to within six inches (6") of ground surface. In new subdivisions when the Sewer services are installed before the curb is constructed, it shall be the Contractor's responsibility to establish the exact location of each Sewer service and to furnish this information to the Engineer. All new house branches and service laterals must be installed greater than 5’-0” from outside edge of manhole and must be between two access structures (i.e. manhole, lamphole). 17-8 MANHOLE CONSTRUCTION AND DROP SEWER CONNECTIONS 17-8.1 General City of Fresno Dept. of Public Works17-17A9 May 2024
Manholes shall be constructed in accordance with Standard Drawings S-2 through S-4 of the City Standard Drawings and as specified herein or directed by the Engineer.Manholes shall be complete structures in place and backfilled including the furnishing and placing of all materials involved. Precast concrete pipe manholes shall consist of a poured in place concrete base section, reinforced concrete pipe section(s), cast iron frame and cover and a poured in place concrete collar with paving patch. Invert channels shall be smooth and semicircular in shape conforming to the inside of the adjacent pipe invert, or flow channels may be provided by use of the bottom half of the specified main pipe. The floor and wall of the manhole outside the channels shall be smooth and shall slope minimum 1:12 towards the channels. The top of the manhole base section shall be keyed to receive the tongue end of the riser section. The key shall be formed in the freshly poured concrete by using a template manufactured to the dimensions of the riser section. If the riser is cast in-place monolithically with the base section by using a slip form or other means, the key may be omitted between the base and riser. If the base and riser sections are not poured monolithically, but separately, a key shall be provided in the base section. In either case, a key will be required in the top of the riser section to receive the tongue end of the tapered cone. The joints between the base and all precast elements of the manhole, including adjustment rings and manhole frame, shall be filled with cement mortar, or approved equal, prior to joining the elements. The interior of the manhole shall be troweled smooth with a wooden trowel, removing excess mortar extruded out of joints for the entire height of the manhole, from the manhole frame to the floor. All excess mortar and any other debris shall be removed from the manhole. 17-8.2 Design and Spacing Sewer lines shall be laid straight between manholes, unless otherwise specified in the Plans and/or Specifications. The installation of lamp holes or clean-outs on public Sewer mains is forbidden. Manholes are to be installed at the end of each line; at all changes in grade, size, or alignment; at all intersections; and at distances not greater than 600 feet. A grade drop of 0.1 foot (30mm) min. shall be provided through manholes, when grade permits. Manholes shall not be installed in flow channels of gutters, or in depressions subject to storm waters or other infiltration, sidewalks, roundabouts, brick crosswalks or have any brick surrounding the manhole cover.
City of Fresno Dept. of Public Works17-18A9 May 2024
Flat-top manholes are not permitted. Minimum depth of manhole above the manholes base shall be 42 inches (1.08 m). 17-8.3 Materials Pre-cast concrete pipe manholes shall consist of a poured in-place concrete base section, reinforced-concrete pipe section(s), a reinforced concrete taper section, grade rings and cast-iron frame and cover.

The formed flow channel depth shall extend above spring line up to half of the pipe. The bench shall slope a minimum 1:12.Changes in direction of flow shall be made with a smooth curve of as large a radius as the size of the manhole will permit. Changes in grade of the channels shall be made gradually and evenly. Where the pipe size of the entering and leaving pipe is different, the larger diameter must be maintained in the manhole. A channel shall be formed in the bottom of all new starting manholes (a terminal manhole at the upstream end of a sewer main) and it shall extend completely through the manhole. The upstream end of the new flow channel shall terminate at the manhole wall, and the end of the flow channel shall be vertical with no fillet between the flow channel bottom and the manhole wall.
City of Fresno Dept. of Public Works17-19A9 May 2024
Stub-outs shall be installed in manholes at the locations and sizes shown on the Plans. All stub-outs shall be sealed with a plug of a type approved by the manufacturer of the pipe. When connecting to the existing stub-outs and the plug is removed, a new square cut shall be done to the existing stub-out prior to connection on the new sewer main. All manholes shall be completed to finish grade with concrete collar and paving patches (where indicated) as shown on the City Standard Drawings and as herein specified. In undeveloped areas where no Street or alley surfacing is to be done in conjunction with or immediately after Utility installation, the manhole cover shall be finished off to a level 1 inch (25mm) above ground elevation and shall be provided with 12 inches (300mm) of grade rings. In existing Street areas where surfacing exists and no new Street regrading is contemplated in conjunction with or immediately after Utility installation, such as new subdivisions, manholes shall initially terminate with the top of the cone 6 inches (150mm) below subgrade and shall be brought to Street or alley surface with grade adjustment rings and completed after Street paving is accomplished. Unless specifically otherwise indicated in the Specifications, it will be the responsibility of the Sewer Contractor to return and install the manhole covers to finish grade as specified and shown on the City Standard Drawings. The Contractor is aware that connections to existing Sewers will be “wet” and the Contractor shall make whatever arrangements are necessary to complete the manhole connections under the “wet” conditions. Where necessary, manholes shall be equipped with an approved water-tight insert placed under the manhole cover to prevent rainwater or other inflow. No steps shall be installed in manholes unless otherwise noted on the Plans. 17-8.5 Abandon and Removal Manholes abandoned in place shall be broken out within 2 inches (0.6m) of the finished grade. The manhole frame and cover will be delivered to the City Corporation Yard. The Sewer mains entering the manholes shall be sealed with concrete and the manhole backfilled with sandy soil and compacted to a relative compaction of 90% using optimum moisture and tested in accordance with ASTM D1557. Manholes to be removed shall have the base removed with the barrel and taper. The manhole frame and cover will be delivered to the City Corporation Yard. After the complete manhole has been removed the excavation will be backfilled in accordance with backfill requirements. Before backfilling, all Sewer pipes that have entered the manhole will be sealed with concrete.
City of Fresno Dept. of Public Works17-20A9 May 2024
17-8.6 Adjustments Where existing manholes need to be raised or lowered to meet a new Street grade, they will be left in place and marked until the Street has been paved. After the paving material has been compacted they will be dug out and the ring and cover removed and lowered or raised to grade by use of concrete around the frame but left two (2) inches below the-finished surface in asphalt concrete Streets and the top two inches filled with A.C. and rolled. In concrete surfaced Streets the concrete will be brought to the surface. "Jiffy Rings" (manhole adjusting riser rings that feature a turnbuckle linkage pivoted at each end, that provide the ultimate means to expand a manhole riser) for raising manholes will be allowed. 17-8.7 Drop Sewer Connections Drop Sewer connections at manholes shall be constructed in accordance with City Standard Drawings S-11A and S-11B, and only at locations approved by the Engineer and shown on the approved Plans. 17-8.8 Payment If existing manholes are to be removed and replaced they shall be included in the bid price of new manholes unless otherwise specified in the Specifications. The bid price of adjusting manholes to the new Street grade shall include surface restoration. 17-9 FUTURE STUB OUTS Stubs shall be installed in the manholes at the locations and of the size shown on the Plans. All stubs shall be sealed with a plug of a type approved by the manufacturer of the pipe for use with his/her product. When connecting to the existing stubs and the plug is removed, a new square circumferentially cut shall be done to the existing stub prior to connection on the new sewer main. 17-10 DEFLECTION TEST OF PVC SEWER LINES PVC Sewer pipe, which is designated as flexible in nature, shall be tested for excessive deflection. This test shall be performed after backfilling and compaction but prior to the placement of aggregate base or asphalt-concrete surfacing, and prior to television inspection as specified in subsection 17-12 of these Specifications. The Contractor shall demonstrate that the maximum pipe deflection does not exceed 5 percent by pulling a properly sized rigid ball or a mandrel through the main line pipe. A “rubber flush ball” does not meet this requirement for deflection testing.
City of Fresno Dept. of Public Works17-21A9 May 2024
Failure of the deflection test shall be grounds for rejection of the section tested, until correction of the reason for the failure and successful retesting of the section. 17-11 LEAKAGE TEST OF SEWER LINES AND SERVICE LATERALS After completing the installation, backfill and compaction of a section of Sewer line with service laterals, and after all other underground Utilities (including gas, electric, telephone, cable television, water and Storm Drain) are in and compacted, but prior to the placement of aggregate base or asphalt-concrete pavement, the Contractor shall, at his/her expense, conduct a leakage test using low pressure air. The test shall be performed using the following procedures and under the Supervision of the inspecting Engineer. Each section of Sewer between two successive manholes shall be tested by plugging all pipe outlets with suitable test plugs. All pneumatic plugs shall be seal tested before being used in the actual test installation. One length of pipe shall be laid on the ground and sealed at both ends with the pneumatic plugs to be checked. Air shall be introduced into the plugs to 170 MPa (25 pounds per square inch) gauge pressure. The sealed pipe shall be pressurized to 35 MPa (5 psig). The plugs shall hold against this pressure without bracing and without movement of the plugs out of the pipe. To commence the leakage test, air shall be slowly added until the internal pressure is raised to 27 MPa (4.0 psig). The compressor used to add air to the pipe shall have a blow-off valve set at 35 MPa (5 psig) to assure that at no time the internal pressure in the pipe exceeds 35 MPa (5 psig). The internal pressure of 27 MPa (4 psig) shall be maintained for at least two minutes to allow the air temperature to stabilize after which the air supply shall be disconnected and the pressure reduced to 24 MPa (3.5 psig). The time in minutes that is required for the internal air pressure to drop from 24 MPa (3.5 psig) to the lower pressure indicated in the appropriate table below shall be measured and the results compared with the values tabulated below. Gauges used to measure test pressures shall read from 0 MPa (0 psig) to 69 MPa (10 psig) maximum with 3.5 MPa (½ psig) increments. If required, the Contractor shall supply necessary fittings to accept a City supplied gauge. All gauging and testing shall be done outside the manholes and no one shall be allowed to enter the manholes while the line is pressurized.

SECTION 18 – GUIDELINES FOR PROPOSED BIKE LANE PROJECTS WITHIN EXISTING STREETS 18-1 GENERAL Purpose: To provide guidelines to encourage the construction of bike lanes in conformance with the City’s General Plan while respecting the privileges of adjoining properties. The Engineer shall apply these guidelines in conformance with sound traffic engineering principles and the City’s General Plan. The Guidelines are as follows: a) To the greatest extent possible, bike lanes will be installed adjacent to existing curbs. In cases where curb parking is permitted, bike lanes will be installed between the parking and travel lanes, whenever possible. b) Consideration will be given to 5-foot bike lanes min. (measured from the face of curb), reduced lane widths, and/or elimination of traffic lanes. A traffic study to investigate traffic speeds, speed limits, type of corridor, volumes of cars and trucks, etc., may be developed before travel lanes are eliminated and/or reduced in width. c) Street parking needs versus available off-Street parking on adjoining properties shall be reviewed. Street parking may be eliminated under the following conditions: 1. The adjoining property has been developed with “back-up or side-yard” treatment to permit alternative parking. 2. The property has sufficient off-site parking on adjoining local Streets. 3. A residential house has sufficient space for three (3) on-site parking spaces. An on-site parking space can mean a garage, a carport, a paved driveway, concrete ribbons, etc., even if such facilities are used for other purposes. Garages converted to living quarters with an approved building permit, shall not count as available parking. 4. Major shopping centers, office complexes, and other development with on-site parking lots, have been developed in conformance with the parking standards adopted by Council in the current City of Fresno Municipal Code. 5. When an adjoining development has sufficient on-site parking, but the space is used for other purposes. 18-2A9 May 2024
d) For smaller, local shopping centers and office complexes, parking will not be deleted if the Street provides the only means of customer access or the elimination of such Street parking causes a severe hardship on the adjoining development. e) Where sufficient road width is not available, frontage roads may be used for bike routes. Ingress and egress will be designed to provide maximum safety to the cyclist. The median shall be opened to allow the bicyclists to the frontage road with a 5' wide by 6" thick P.C.C. riding surface. Frontage roads will be designated Bike Routes with “Bike Route” signs at the beginning of the route. f) More circuitous, alternate bike routes will be considered as a last resort. g) Construction of parking bays and the reduction of frontage road islands and median islands, may be considered if the costs are not prohibitive. The aesthetics of median islands must be maintained. h) Staff will consult with the bicycle clubs and send mailings to adjoining neighbors and/or businesses before Street parking is eliminated. Property owners who object to elimination of parking in front of their properties or disagree with the implementation of these guidelines, may file a written protest to the Engineer. The Engineer will make a final determination (in writing) within 10 Days after receipt of the written protest. Property owners with back-up treatments (rear of property faces proposed Street) will not receive a mailer. i) At all Street intersections, the bicycle symbol shall be painted at a point 25 feet from the return and every 800 feet (maximum) of continuous bike lane. j) “Bike Lane” signs shall be installed at the beginning of a bike lane and every ½ mile of continuous bike lane. A “Bike Route” sign shall also be installed where the bike lane changes to a bike route. Bike lane supplementary “Begin” and “End” signs shall not be installed. k) Major Street bike lane striping shall be a single stripe at locations where the bike lane is adjacent to the curb and two stripes where the bike lane is between the travel way and the parking lane with 13' or wider distance available. The bicycle pavement marker shall be centered in the area where the bicyclists are expected to ride.l) Bike lane striping shall be applied using thermoplastic paint conforming to State Standard Specifications Section 84-2. Bicycle legend shall be applied using “Legend Build Paint” or approved equal. m) On extra wide Streets that are not developed with their ultimate lane configuration, the bike lanes will be installed at their ultimate location. 18-3A9 May 2024
n) Bike lane and bike route signs shall be a minimum of 18" x 24" and shall have an anti-graffiti coating and attached with theft-proof “U” bolts. o) “No Stopping Anytime” signs will be installed at intervals of 200 feet (or at intervals determined by existing streetlight poles) when striping a curb side bike lane. At a bus stop without a bus bay, the bike lane stripe will be painted through the bus stop.
