General Conditions 1400-15 The wage rates set forth are the minimum that may be paid by the Contractor. Nothing herein contained shall be construed as preventing the Contractor from paying more than the minimum set forth. No extra compensation whatever shall be allowed by the City due to the inability of the Contractor to hire labor at the minimum rate nor for any necessity for payment by the Contractor for subsistence, travel time, overtime, or other added compensation, all of which possibilities are elements to be considered and ascertained to the Contractor's own satisfaction in preparing the bid. If it becomes necessary to employ a craft other than those listed, the Contractor shall notify the City immediately and the City will determine the additional prevailing rate from the Director of the Department of Industrial Relations and the rate thus determined shall be applicable as a minimum at the time of initial employment. The Contractor shall pay travel and subsistence payments to workers needed to execute the work as such travel and subsistence payments are defined in the applicable collective bargaining agreement filed with the Department of Industrial Relations pursuant to Labor Code Section 1773.8.

Section 1777.5 requires the Contractor or subcontractors employing tradespersons in any apprenticeable occupation to apply to the joint apprenticeship committee nearest the site of the project and which administers the apprenticeship program in that trade for a certificate of approval. The Contractor and subcontractors are required to submit contract award information to the applicable joint apprenticeship committee. As provided for in Section 1777.5 of the Labor Code, the Contractor is required to make contributions to funds established for the administration of apprenticeship programs.

This requirement shall apply continuously and not be limited to normal working hours. Safety provisions shall conform to U.S. Department of Labor (OSHA), the California Occupational Safety and Health Act, and all other applicable Federal, State, County, and local laws, ordinances, codes, the requirements set forth below, and any regulations that may be detailed in other parts of these Documents. Where any of these are in conflict, the more stringent requirement shall be followed. The completed Work shall include all necessary permanent safety devices, such as machinery guards and similar ordinary safety items, required by the State and Federal (OSHA) industrial authorities and applicable local and national codes. Further, any features of the Work, including City-selected equipment, subject to such safety regulations shall be fabricated, furnished, and installed in compliance with these requirements. All equipment furnished shall be grounded and provided with guards and protection as required by safety codes. Where vapor-tight or explosion-proof electrical installation is required by safety codes, this shall be provided. Contractors and manufacturers of equipment shall be held responsible for compliance with the requirements included herein. The Contractor shall notify all equipment suppliers and subcontractors of the provisions of this paragraph. Before proceeding with any construction work, the Contractor shall take the necessary action to comply with all provisions for safety and accident prevention.

Shoring, bracing, sloping, or other protective system shall not be less effective than required by the California Construction Safety orders. General Conditions 1400-18 If death or serious injuries or serious damages are caused, the accident shall be reported immediately by telephone or messenger to the City. In addition, the Contractor must promptly report in writing to the City Engineer all accidents whatsoever arising out of, or in connection with, the performance of the Work whether on, or adjacent to, the Site, giving full details and statements of witnesses. The Contractor shall make all reports as are, or may be, required by any authority having jurisdiction, and permit all safety inspections of the work being performed under this Contract. If a claim is made by anyone against the Contractor or any subcontractor on account of any accident, the Contractor shall promptly report the facts in writing to the City Engineer, giving full details of the claim. 5.0 CONTROL OF WORK AND MATERIALS 5.1 Means and Methods It is expressly stipulated that the drawings, specifications and other Contract Documents set forth the requirements as to the nature of the completed Work and do not purport to control the method of performing work except in those instances where the nature of the completed Work is dependent on the method of performance. Except as provided elsewhere in the Contract Documents, neither the City, its consultants, or the City Engineer will be responsible for or have control or charge of construction means, methods, techniques, sequences or procedures, or for safety precautions and programs in connection with the Work. Except as provided elsewhere in the Contract Documents, neither the City, its consultants, or the City Engineer will be responsible for or have control or charge over the acts or omissions of the Contractor, or any of their subcontractors, agents or employees, or any other persons performing any of the Work. Any general control of the Work exercised by the City or its authorized representatives shall not make the Contractor an agent of the City, and the liability of the Contractor for all damages to persons and/or to public or private property arising from the Contractor's execution of the Work shall not be lessened because of such general control. Neither the inspection by the City, its consultants, or the City Engineer, nor any order, measurement, approved modification, or payment of monies, nor acceptance of any part or whole of the Work by the City, the City Engineer or the consultant, or their agents, shall operate as a waiver of any provision of the Contract. Acceptance by the City, it consultants, or the City Engineer of any drawings, methods of work, or any information regarding materials and equipment the Contractor proposes to furnish in the Work shall not be regarded as an assumption of risks or liability by the City, its consultants, or the City Engineer, or any officer or employee thereof, and the Contractor shall have no claim under the Contract on account of the failure or partial failure or inefficiency or insufficiency of any plan or method of work or material and equipment so accepted. Such acceptance shall be considered to mean merely that the City, its consultants, or the City Engineer has no objection to the Contractor using, upon its own full responsibility, the plan or method of work proposed, or furnishing the materials and equipment proposed. General Conditions 1400-19 5.2 City-Furnished Materials Materials, if furnished by the City, will be made available as designated in the Specific Project Requirements. The cost of loading, unloading, hauling and handling, and placing City-furnished materials shall be considered as included in the price bid for the Contract item involving such City-furnished material. Contractor shall inspect and assure himself of the amount and soundness of such materials. The Contractor will be held responsible for all materials furnished to it and shall pay all demurrage and storage charges. City-furnished materials lost or damaged from any cause whatsoever shall be replaced by the Contractor. The Contractor will be liable to the City for the cost of replacing City-furnished material and such costs may be deducted from any monies due or to become due the Contractor. 5.3 Defective and Unauthorized Work Materials and workmanship not conforming to the requirements of the Contract Documents shall be considered defective and will be subject to rejection. Defective work or material, whether in place or not, shall be removed immediately from the Site by the Contractor, at its expense, when so directed by the City Engineer. Any work done beyond the limits of work, lines, and grades shown on any approved plans or established by the City Engineer, or any extra work done without written authority, will be considered as unauthorized and will not be paid for. Upon failure on the part of the Contractor to comply with any order of the City Engineer made under the provisions of this section, the City Engineer shall have authority to cause defective work to be remedied, or removed and replaced, and unauthorized work to be removed, and to deduct the costs thereof from any monies due or to become due the Contractor. The time, cost and compliance requirements stipulated in Paragraph 1400- 3.4, City's Right to Carry Out the Work, shall apply for this paragraph also. 5.4 Unnoticed Defects Any defective work or material that may be discovered by the City, its consultants, or the City Engineer before the final acceptance of the Work, or before final payment has been made, or during the warranty period, shall be removed and replaced by work and materials which shall conform to the provisions of the Contract Documents. Failure on the part of the City, its consultants, or the City Engineer to condemn or reject bad or inferior work or materials shall not be construed to imply acceptance of such work or materials. General Conditions 1400-20 5.5 Right to Retain Imperfect Work If any part or portion of the work performed or material furnished under this Contract shall prove defective and not in accordance with the Drawings and Specifications, and if the imperfection in the same shall not be of sufficient magnitude or importance as to make the work dangerous or unsuitable, or if the removal of such work will create conditions which are dangerous or undesirable, the City shall have the right and authority to retain such work but shall make such deductions in the final payment therefor as may be just and reasonable. 6.0 PROGRESS OF THE WORK 6.1 Beginning of Work The Contractor shall begin work within ten (10) days after receiving Notice to Proceed and shall diligently prosecute the same to completion within the time limit. Should the Contractor begin work in advance of receiving Notice to Proceed, any work performed in advance of the said date of approval shall be considered as having been done by the Contractor at its own risk and as a volunteer. 6.2 Time of Completion Time shall be of the essence of the Contract. The Contractor shall prosecute the work so that the various portions of the project shall be complete and ready for use within the time specified in Paragraph 3000-1.6 TIME ALLOWED FOR COMPLETION. It is expressly understood and agreed by and between the Contractor and the City that the Contract time for completion of the work described herein is a reasonable time taking into consideration the average climatic and economic conditions and other factors prevailing in the locality and the nature of the work. 6.3 Delays 6.3.1 Notice of Delays - When the Contractor foresees a delay in the prosecution of the Work and, in any event, immediately upon the occurrence of a delay, the Contractor shall notify the City Engineer in writing of the probability of the occurrence and the estimated extent of the delay, and its cause. The Contractor shall take immediate steps to prevent, if possible the occurrence or continuance of the delay. The Contractor agrees that no claim shall be made for delays which are not called to the attention of the City Engineer at the time of their occurrence. 6.3.2 Avoidable Delays - Avoidable delays in the prosecution of the Work shall include delays which could have been avoided by the exercise of care, prudence, foresight, and diligence on the part of the Contractor or its subcontractors, at any tier level, or suppliers. General Conditions 1400-21 6.3.3 Unavoidable Delays - Unavoidable delays in the prosecution or completion of the Work shall include delays which result from causes beyond the control of the Contractor and which could not have been avoided by the exercise of care, prudence, foresight, and diligence on the part of the Contractor or his subcontractors, at any tier level, or suppliers. Delays in completion of the Work of other Contractors employed by the City will be considered unavoidable delays insofar as they interfere with the Contractor's completion of the current critical activity item of the Work. 6.3.3.1 Abnormal Delays - Delays caused by acts of god, fire, unusual storms, floods, tidal waves, earthquakes, strikes, labor disputes, freight embargoes, and shortages of materials shall be considered as unavoidable delays insofar as they prevent the Contractor from proceeding with at least seventy-five (75) percent of the normal labor and equipment force for at least five (5) hours per day toward completion of the current critical activity item on the favorably reviewed progress schedule. 6.3.3.2 Material Shortages - Upon the submission of satisfactory proof to the City Engineer by the Contractor, shortages of material will be acceptable as grounds for granting a time extension. In order that such proof may be satisfactory and acceptable to the City Engineer, it must be demonstrated by the Contractor that the Contractor has made every effort to obtain such materials from all known sources within reasonable reach of the proposed Work. Only the physical shortage of material, caused by unusual circumstances, will be considered under these provisions as a cause for extension of time, and no consideration will be given to any claim that material could not be obtained at a reasonable, practical, or economical cost or price, unless it is shown to the satisfaction of the City Engineer that such material could have been obtained only at exorbitant prices entirely out of line with current rates, taking into account the quantities involved and usual practices in obtaining such quantities. A time extension for shortage of material will not be considered for material ordered or delivered late or whose availability is affected by virtue of the mishandling of procurement. The above provisions apply equally to equipment to be installed in the work. 6.4 Time Extensions 6.4.1 Avoidable Delay - The City may grant an extension of time for avoidable delays if the City deems it is in its best interest. If the City grants an extension of time for avoidable delays, the Contractor agrees to pay the City's actual costs, including charges for engineering, inspection and administration incurred during the extension. 6.4.2 Unavoidable Delay - If the Contractor is delayed in the performance of its work by an act of the City or if the Contractor is delayed in the performance of its work by an unavoidable delay, then the Contract completion date may be extended by the City for such time that, in the City's and City Engineer's opinion, the Contractor's completion date will be unavoidably delayed, provided that the Contractor strictly fulfills the following: General Conditions 1400-22 a. The Contractor shall provide notification, in accordance with Paragraph 1400-6.3.1, Notice of Delays and submit in writing a request for an extension of time to the City Engineer stating at a minimum the probable cause of the delay and the number of days being requested. The time extension request shall be submitted in accordance with the requirements of Paragraph 2000-4.3, TIME IMPACT ANALYSIS. b. If requested by the City Engineer, the Contractor shall promptly provide sufficient information to the City Engineer to assess the cause or effect of the alleged delay, or to determine if other concurrent delays affected the work. c. Weather Delays. The Contractor will be granted a non-compensable time extension for weather caused delays. Should the Contractor fail to fulfill any of the foregoing, which are considered conditions precedent to the right to receive a time extension, the Contractor waives the right to receive a time extension. Should the Contractor fail to complete the work within the time specified in the contract, as extended in accordance with this clause if appropriate, the Contractor shall pay to the City liquidated damages in accordance with Section 1500, Paragraph 1500- 2.1, Liquidated Damages. During such extension of time, neither extra compensation for engineering, inspection and administration nor damages for delay will be charged to the Contractor. It is understood and agreed by the Contractor and City that time extensions due to unavoidable delays will be granted only if such unavoidable delays involve controlling operations which would prevent completion of the whole Work within the specified Contract time. 6.4.3 Indirect Overhead - The Contractor shall be reimbursed for indirect overhead expenses for periods of time when the Work is stopped due to delays as defined in Paragraph 1400-6.3.3, Unavoidable Delay. However, no reimbursement for indirect overhead shall be made for delays as defined in Paragraphs 1400-6.3.3.1, Abnormal Delays; 1400-6.4.2c, Weather Delays; or 1400-6.3.3.3, Material Shortages. As a condition precedent to any reimbursement, the Contractor must fulfill all conditions as provided in Paragraph 1400-6.4.2, Unavoidable Delay. The reimbursement of indirect overhead is limited to those delay conditions defined above when the Contractor is prevented from proceeding with seventy-five (75) percent of the normal labor and equipment force for at least five (5) hours per day toward completion of the current critical activity item(s) on the current favorably reviewed progress schedule. 6.4.3.1 Indirect Field Overhead - For those allowable delay periods as defined in Paragraph 1400-6.4.3, Indirect Overhead, the Contractor shall be reimbursed for its indirect field overhead based on: General Conditions 1400-23 a. Invoices for all field office equipment. b. Actual salary for field office staff. c. Fair rental values acceptable to the City Engineer as described in Paragraph 1400-8.3, Force Account Payment for construction equipment idled due to the delay. 6.4.3.2 Home Office Overhead - For those allowable delay periods as defined in Paragraph 1400-6.4.3, Indirect Overhead, the Contractor shall be reimbursed for its home office overhead based on the following formula: Contract Bid Price divided by Contract Period Days x $0.03 = Daily Home Office Overhead ($/Day) Such reimbursement shall be mutually agreed between the City and Contractor to encompass full payment for any home office overhead expenses for such periods of time for the Contractor and all subcontractors. The Contractor agrees to hold the City harmless for any indirect overhead claims from its subcontractors. 6.5 Temporary Suspension of Work 6.5.1 If the Contractor fails to correct defective work as required by Paragraph 1400-5.3, Defective and Unauthorized Work, or fails to carry out the Work in accordance with the Contract Documents or any other applicable rules and regulations, the City, by a written order of the City Engineer or a representative specifically empowered to do so, may order the Contractor to stop the work, or any portion thereof, until the cause for such order has been eliminated; however, this right of the City to stop the Work shall not give rise to any duty on the part of the City to exercise this right for the benefit of the Contractor or any other person or entity. All delays in the Work occasioned by such stoppage shall not relieve the Contractor of any duty to perform the Work or serve to extend the time for its completion. Any and all necessary corrective work done in order to comply with the Contract Documents shall be performed at no cost to the City. 6.5.2 In the event that a suspension of Work is ordered, as provided in this paragraph, the Contractor, at its expense, shall perform all work necessary to provide a safe, smooth, and unobstructed passageway through construction for use by public, pedestrian, and vehicular traffic, during the period of such use by suspension. Should the Contractor fail to perform the Work as specified, the City may perform such work and the cost thereof may be deducted from monies due the Contractor under the Contract. 6.5.3 The City shall also have authority to suspend the Work wholly or in part, for such period as the City may deem necessary, due to unsuitable weather, or to such other conditions as are considered unfavorable for the suitable prosecution of the Work. Such temporary suspension of the Work will be considered justification for time extensions to the Contract in an amount equal to the period of such suspension. The Contractor as directed by the City shall provide the provisions as stipulated in Paragraph 1400-6.6.2 above. Such additional work shall be compensated as provided for in Paragraph 1400-7.0, CHANGES IN SCOPE OF WORK. General Conditions 1400-24 6.6 Termination of Contract If at any time the Contractor is determined to be in material breach of the Contract, notice thereof in writing will be served upon the Contractor and its sureties, and should the Contractor neglect or refuse to provide means for a satisfactory compliance with the Contract, as directed by the City Engineer, within the time specified in such notice, the City shall have the authority to terminate the operation of the Contract. Upon such termination, the Contractor shall discontinue the Work, or such parts of it as the City may designate. Upon such termination, the Contractor's control shall terminate and thereupon the City or its fully authorized representative may take possession of all or any part of the Contractor's materials, tools, equipment, and appliances upon the premises and use the same for the purposes of completing the Work and hire such force and buy or rent such additional machinery, tools, appliances, and equipment, and buy such additional materials and supplies at the Contractor's expense as may be necessary for the proper conduct of the Work and for the completion thereof; or the City may employ other parties to carry the Contract to completion, employ the necessary workers, substitute other machinery or materials and purchase the materials contracted for, in such manner as the City may deem proper; or the City may annul and cancel the Contract and relet the Work or any part thereof. Any excess of cost arising there from over and above the Contract price will be charged against the Contractor and its sureties, who will be liable therefore. In the event of such termination, all monies due the Contractor or retained under the terms of this Contract shall be held by the City in an escrow account; however, such holdings will not release the Contractor or its sureties from liability for failure to fulfill the Contract. Any excess cost over and above the Contract Amount incurred by the City arising from the termination of the operations of the Contract and the completion of the Work by the City as above provided shall be paid for by any available funds in the escrow account. The Contractor will be so credited with any surplus remaining after all just claims for such completion have been paid. 7.0 CHANGES IN THE SCOPE OF WORK 7.1 Change Orders 7.1.1 Without invalidating the Contract and without notice to sureties or insurers, the City, through the City Engineer, may at any time or from time to time, order additions, deletions, or revisions in the Work; these will be authorized by Field Directive, Field Order, or Change Order. A Change Order will not be issued for a Field Directive unless the City Engineer concurs with an appeal by the Contractor that such Field Directive is a change in the scope of the Contract. The Contractor shall comply promptly with the requirements for all Change Orders, Field Orders, or Field Directives. The work involved in Change Orders shall be executed under the applicable conditions and requirements of the Contract Documents. If any Field Order causes an increase or decrease in the Contract Amount or an extension or shortening of the Contract Time, an equitable adjustment will be made by issuing a Change Order. If the Contractor accepts a Change Order that does not include a time extension, the Contractor waives any claim for additional time for the work covered by that Change Order. General Conditions 1400-25 Additional or extra work performed by the Contractor without written authorization of a Field Order or Change Order will not entitle the Contractor to an increase in the Contract Amount or an extension of the Contract Time. 7.1.2 Extra work shall be that work not shown or detailed on the Contract Drawings and not specified. Such work shall be governed by all applicable provisions of the Contract Documents. In giving instructions, the City Engineer shall have authority to make minor changes in the work, not involving extra cost, and not inconsistent with the purposes of the work; but otherwise, except in an emergency endangering life or property, no extra work or change shall be made unless in pursuance of a written order by the City through the City Engineer, and no claim for an addition to the total amount of the Contract shall be valid unless so ordered. 7.1.3 In case any change increases or decreases the work shown, the Contractor shall be paid for the work actually done at a mutually agreed upon adjustment to the Contract price, based upon the provisions of Paragraph 1400-8.0 PROJECT MODIFICATION PROCEDURES 7.1.4 If the Contractor refuses to accept a Change Order, the City may issue it unilaterally. The Contractor shall comply with the requirements of the Change Order. The City shall provide for an equitable adjustment to the Contract and compensate the Contractor accordingly. If the Contractor does not agree that the adjustment is equitable, it may submit a claim in accordance with Paragraph 1400-7.3.2, Claims. 7.2 Differing Site Conditions Pursuant to Public Contract Code Section 7104, the Contractor shall promptly, and before such conditions are disturbed, notify the City Engineer in writing, of any: a. Material that the Contractor believes may be material that is hazardous waste, as defined in Section 25117 of the Health and Safety Code that is required to be removed to a Class I, Class II, or Class III disposal site in accordance with provisions of existing law. b. Subsurface or latent physical conditions at the site differing from those indicated. c. Unknown physical conditions at the site of any unusual nature, differing materially from those ordinarily encountered and generally recognized as inherent in work of the character provided for in the Contract. The City shall promptly, investigate the conditions, and if it finds that the conditions do materially differ, or do involve hazardous waste, and cause a decrease or increase in the Contractor's cost of, or the time required for, performance of any part of the work the City shall cause to be issued a change order under the procedures provided in Paragraph 1400- 7.1, Change Orders. General Conditions 1400-26 In the event that a dispute arises between the City and the Contractor whether the conditions materially differ, or involve hazardous waste, or cause a decrease or increase in the Contractor's cost of, or time required for, performance of any part of the work, the Contractor shall not be excused from any scheduled completion date provided for by the Contract, but shall proceed with all work to be performed under the Contract. The Contractor shall retain any and all rights provided either by Contract or by law which pertain to the resolution of disputes and protests between the contracting parties, Paragraph 1400-7.3, Resolution of Disputes. No claim of the Contractor under this clause shall be allowed unless the Contractor has given the notice required. 7.3 Resolution of Disputes 7.3.1 Contract Interpretation by the City Engineer - Questions regarding the meaning and intent of the Contract Documents shall be referred in writing by the Contractor to the City Engineer. The City Engineer shall respond to the Contractor in writing with a decision. 7.3.2 Claims - Submission of a claim, properly certified, with all required supporting documentation, and written rejection or denial of all or part of the claim by the City, is a condition precedent to any action, proceeding, litigation, suit or demand for arbitration by the Contractor. 7.3.2.1 Notice - If the Contractor disagrees with the City Engineer's decision in Paragraph 1400-7.3.1, Contract Interpretation by the City Engineer, or in any case where the Contractor deems additional compensation or a time extension to the Contract period is due him for work or materials not covered in the Contract or which the City Engineer has not recognized as extra work, the Contractor shall notify the City Engineer, in writing, of his intention to make claim. Claims pertaining to decisions provided in Paragraph 1400-7.3.1 shall be filed in writing to the City Engineer within five (5) days of receipt of such decision. All other claims notices for extra work shall be filed in writing to the City Engineer prior to the commencement of such work. Written notice shall use the words "Notice of Potential Claim". Such Notice of Potential Claim shall state the circumstances and the reasons for the claim but need not state the amount. Additionally, no claim for additional compensation or extension of time for a delay will be considered unless the provisions of Paragraphs 1400-6.3, Delays, and 6.4, Time Extensions, are complied with. No claim filed after the date of final payment will be considered. It is agreed that unless notice is properly given, the Contractor shall not recover costs incurred by him as a result of the alleged extra work, changed work or other situation which had proper notice been given would have given rise to a right for additional compensation. The Contractor should understand that timely notice of potential claim is of great importance to the City and is not merely a formality. Such notice allows the City to consider preventative action, to monitor the Contractor's increased costs resulting from the situation, to marshal facts, and to plan its affairs. Such notice by the Contractor, and the fact that the City Engineer has kept account of the cost as aforesaid, shall not in any way be construed as proving the validity of the claim. General Conditions 1400-27 7.3.2.2 Submission of claim costs - Within 30 days after the last cost of work for which the Contractor contends additional compensation is due, but if costs are incurred over a span of more than 30 days, then within 15 days after the thirtieth day and every month thereafter, the Contractor shall submit to the City Engineer the costs incurred for the claimed matter. Claims shall be made in itemized detail satisfactory to the City Engineer in content, detail and format of presentation. If the additional costs are in any respect not knowable with certainty, they shall be estimated. If the claim is found to be just, it shall be allowed and paid for as provided in Section 1400-8.0, PROJECT MODIFICATION PROCEDURES. 7.3.2.3 Affidavit required - All claims submitted to the City shall be accompanied with a type written affidavit containing the following language; it must be signed, dated, and notarized on the Contractor's letterhead: I, (must be an officer) , being the (title) of (contractor's name) , declare under penalty of perjury under the laws of the state of California, and do personally certify and attest that: I have thoroughly reviewed the attached claim for additional compensation and/or extension of time, and know its contents, and said claim is made in good faith; the supporting data is truthful and accurate; the amount requested accurately reflects the contract adjustment for which the contractor believes the City of La Quinta is liable; and further, that I am familiar with California Penal Code Section 72 and California Government Code Section 12560, Et Seq, pertaining to false claims, and further know and understand that submission or certification of a false claim may lead to fines, imprisonment and/or other severe legal consequences. 7.3.2.4 Claim meetings - From time to time the City Engineer may call special meetings to discuss outstanding claims. The Contractor shall cooperate and attend, prepared to discuss outstanding claims, making available the personnel necessary for claim resolution, and providing documents reasonably requested by the City Engineer. 7.3.3 Resolution of Claims - For all contracts awarded during the effective dates of Public Contract Code Section 20104, where claims cannot be resolved between the parties, claims for three hundred and seventy-five thousand dollars ($375,000) or less shall be resolved pursuant to the provisions of that code section, which is summarized in Paragraphs 1400-7.3.3.1 to 1400-7.3.3.5.

Upon a demand, the City shall schedule a meet and conference within 30 days for settlement of the dispute. 7.3.3.4 Claim Filing - If the claim or any portion remains in dispute after the claim conference noted in Paragraph 1400-7.3.3.4, Claim Conference, the Contractor may file a claim pursuant to Chapter 1 (commencing with Section 900) and Chapter 2 (commencing with Section 910) of Part 3 of Division 3.6 of Title 1 of the Government Code. For purposes of those provisions, the running of the period of time within which a claim must be filed shall be tolled from the time the Contractor submits his or her written claim pursuant to Paragraph 1400-7.3.2, Claims, until the time the claim is denied, including any period of time utilized in the meet and confer process. 7.3.3.5 Civil Actions for Claims Less Than $375,000 - The following procedures are established for all civil actions filed to resolve claims for less than three hundred seventy-five thousand dollars ($375,000): General Conditions 1400-29 a.

The mediation process shall provide for the selection within 15 days by both parties of a disinterested third person as mediator, shall be commenced within 30 days of the submittal, and shall be concluded within 15 days from the commencement of the mediation unless a time requirement is extended upon a good cause showing to the court. b. If the matter remains in dispute, the case shall be submitted to judicial arbitration pursuant to Chapter 2.5 (commencing with Section 1141.10) of Title 3 of Part 3 of the Code of Civil Procedure, notwithstanding Section 1141.11 of that Code.

Arbitration shall not be used for resolution of these disputes. Should either party to this Contract bring legal action against the other, the case shall be handled in the California county where the work is being performed. 7.3.4 Records of Disputed Work - In proceeding with a disputed portion of the Work, the Contractor shall keep accurate records of its costs and shall make available, to the City Engineer, a daily summary of the hours and classification of equipment and labor utilized on the disputed work, as well as a summary of any materials or any specialized services which are used. Such information shall be submitted to the City Engineer on a monthly basis, receipt of which shall not be construed as an authorization for or acceptance of the disputed work. 8.0 PROJECT MODIFICATION PROCEDURES 8.1 Changes in Contract Price Whenever corrections, alterations, or modifications of the work under this Contract are ordered by the City Engineer and approved by the City and increase the amount of work to be done, such added work shall be known as extra work; and when such corrections, alterations, or modifications decrease the amount of work to be done, such subtracted work shall be known as work omitted. General Conditions 1400-30 The difference in cost of the work affected by such change will be added to or deducted from the amount of said Contract price, as the case may be, by a fair and reasonable valuation, which shall be determined in one or more of the following ways as directed by the City Engineer: a. By unit prices subsequently fixed by agreement between the parties; b. By an acceptable lump sum proposal from the Contractor; or c. By Force Account (as described in Paragraph 1400-8.3, Force Account Payment), when directed in writing and administered by the City through its agents. When required by the City Engineer, the Contractor shall submit, in the form prescribed by the City Engineer, an itemized breakdown with supporting data of the quantities and prices used in computing the value of any change that may be ordered. The City Engineer will review the Contractor's proposal for the change and negotiate an equitable adjustment with the Contractor. After there is an agreement the City Engineer will prepare and process the Change Order and make a recommendation for action by the City. All Change Orders must be approved by the City in writing before the work can be authorized and the Change Order executed. The prices agreed upon and any agreed upon adjustment in Contract Time shall be incorporated in the written order issued by the City, which shall be written so as to indicate an acceptance on the part of the Contractor as evidenced by its signature. By signature of the Change Order, the Contractor acknowledges that the adjustments to cost and time contained in the Change Order are in full satisfaction and accord, payment in full, and so waives any right to claim further cost and time impacts at any time during and after completion of the Contract for the changes encompassed by the Change Order. 8.2 Negotiated Change Orders Under the methods described in Paragraph 1400-8.1b and 8.1c above, the Contractor shall submit substantiating documentation with an itemized breakdown of Contractor and subcontractor direct costs, including labor, material, equipment rentals, and approved services, pertaining to such ordered work in the form and detail acceptable to the City Engineer. The direct costs shall include only the payroll cost for workers and foremen, including wages, fringe benefits as established by negotiated labor agreements or state prevailing wages, workers' compensation and labor insurance, and labor taxes as established by law. No other fixed labor burdens will be considered, unless approved in writing by the City Engineer; the cost of materials used and equipment delivered and installed in such work as substantiated by appropriate documents; the cost of construction machinery and equipment based on fair rental or ownership values acceptable to the City Engineer as described in Paragraph 1400-8.3, Force Account Payment; and the cost of incidentals directly related to such work. The direct costs shall not include any labor or office costs pertaining to the Contractor's managers or superintendents, his office and engineering staff and office facilities, or anyone not directly employed on such work, nor the cost of rental of small tools as all such indirect costs form a part of the Contractor's overhead expense. General Conditions 1400-31 Under the method described in Paragraph 1400-8.1b and 8.1c the maximum percentage which will be allowed for the Contractor's combined overhead and profit will be: a. For work by its own organization, the Contractor may add the following percentages: • Direct Labor 25 percent • Materials 15 percent • Equipment (owned or rented) 15 percent b. For all such work done by subcontractors, such subcontractor may add the same percentages as the Contractor as listed in (1) above to its actual net increase in costs for combined overhead and profit and the Contractor may add up to ten (10) percent of the subcontractor's total for its combined overhead and profit. c. For all such work done by subtier-subcontractors, such sub-subcontractors may add the same percentages as the Contractor as listed in (1) above to its actual net increase in costs for combined overhead and profit and the subcontractor may add up to ten (10) percent of the sub-subcontractor's total for his combined overhead and profit. The Contractor may add up to five (5) percent of the subcontractor's total for its combined overhead and profit. d. To the total of the actual costs and fees allowed hereinunder, not more than two (2) percent shall be added for additional bond and insurance other than labor insurance. The above fees represent the maximum limits which will be allowed, and they include the Contractor's and all subcontractors' indirect home office expenses and all costs for cost proposal preparation. When both additions and credits are involved in any one change, the combined overhead and profit shall be figured on the basis of the net increase, if any, for each area of work, i.e. direct labor, materials, equipment, and subcontractors. The amount of credit to be allowed by the Contractor to the City for any such change which results in a net decrease in cost will be the amount of the actual net decrease and a credit in accordance with the markups allowed under the use of the method described in Paragraph 1400-8.3, Force Account Payment. The Contractor shall not claim for anticipated profits on work that may be omitted. 8.3 Force Account Payment If either the amount of work or payment for a Change Order cannot be determined or agreed upon beforehand, the City may direct by written Change Order or Field Order that the work be done on a force account basis. The term "force account" shall be understood to mean that payment for the work will be done on a time and expense basis, that is, on an accounting of the Contractor's forces, materials, equipment, and other items of cost as required and used to do the work. For the work performed, payment will be made for the documented actual cost of the following: General Conditions 1400-32 a. Direct labor cost for workers, including foremen, who are directly assigned to the force account work: Direct labor cost is the actual payroll cost, including wages, fringe benefits as established by negotiated labor agreements or state prevailing wages, workers' compensation and labor insurance, and labor taxes as established by law. No other fixed labor burdens will be considered, unless approved in writing by the City. b. Material delivered and used on the designated work, including sales tax, if paid for by the Contractor or its subcontractor. c. Equipment rental, including necessary transportation for items having a value in excess of One Thousand Dollars ($1,000.00). d. Additional bond. e. Additional insurance, other than labor insurance. To the preceding costs, there shall be added the following fees for the Contractor, subcontractor, or sub-subcontractor actually performing the work: • A fixed fee not to exceed fifteen (15) percent of the costs of Items a, b, and c above. • To the total of the actual costs and fees allowed hereunder, not more than two (2) percent shall be added for additional bond and insurance as the cost of Items d and e above. For work performed by an approved subcontractor, the Contractor may add to the total of the actual costs and fixed fees allowed under the preceding paragraph an additional fixed fee of five (5) percent of said total. No further compensation will be allowed for the Contractor's administration of the work performed by the subcontractor. For work performed by a sub tier-subcontractor, the subcontractor may add to the total of the actual costs and fixed fees allowed under the preceding paragraph an additional fixed fee of five (5) percent of said total. No further compensation will be allowed for the subcontractor's administration of the work performed by the sub tier-subcontractor. The Contractor may add to the total of the actual costs and fixed fees allowed under this paragraph an additional fixed fee of five (5) percent of said total. No further compensation will be allowed for the Contractor's administration of the work performed by the subcontractor. The added fixed fees shall be considered to be full compensation, covering the cost of general supervision, overhead, profit, and any other general expense. The above fixed fees represent the maximum limits which will be allowed, and they include the Contractor's and all subcontractors' indirect home office expenses and all costs for cost proposal preparation and record keeping. The City reserves the right to furnish such materials and equipment as it deems expedient, and the Contractor shall have no claim for profit or added fees on the cost of such materials and equipment. General Conditions 1400-33 For equipment under Item c above, rental or equivalent rental cost will be allowed for only those days or hours during which the equipment is in actual use. Payment shall be based on actual rental and transportation invoices but shall not exceed the monthly rate in the Rental Rate Blue Book. Owner-operated equipment rates shall not exceed the monthly rate in the Rental Rate Blue Book plus the labor costs as provided in Item a. above. The rental cost allowed for equipment will, in all cases, be understood to cover all fuel, supplies, repairs, ownership, and incidental costs and no further allowances will be made for those items, unless specific agreement to that effect is made. For Contractor owned equipment, the rental rate shall be as listed for such equipment in the California Department of Transportation publication entitled "Labor Surcharge and Equipment Rental Rates", which is in effect on the date the work is accomplished. When equipment is not listed in said publication, a suitable rental rate for such equipment will be established by the City Engineer. Prior to the commencement of force account work, the Contractor shall notify the City Engineer of its intent to begin work. Labor, equipment and materials furnished on force account work shall be recorded daily by the Contractor upon report sheets furnished by the City Engineer to the Contractor. The reports, if found to be correct, shall be signed by both the Contractor and City Engineer, or inspector, and a copy of which shall be furnished to the City Engineer no later than the working day following the performance of said work. The daily report sheet shall thereafter be considered the true record of force account work provided. The Contractor shall maintain its records in such a manner as to provide a clear distinction between the direct costs of work paid for on a force account basis and the costs of other operations. To receive partial payments and final payment for force account work, the Contractor shall submit, in a manner approved by the City Engineer, detailed and complete documented verification of the Contractor's and any of its subcontractor's actual costs involved in the force account pursuant to the pertinent Change Order or Field Order. Such costs shall be submitted within thirty (30) days after said work has been performed. No payments will be made for work billed and submitted to the City Engineer after the thirty (30) day period has expired. The force account invoice shall itemize the materials used and shall cover the direct costs of labor and the charges for equipment rental, whether furnished by the Contractor, subcontractor, or other forces. The invoice shall be in a form acceptable to the City Engineer and shall provide names or identifications and classifications of workers, the hourly rate of pay and hours worked, and also the size, type, and identification number of equipment and hours operated. Material charges shall be substantiated by valid copies of vendor's invoices. When both additions and credits are involved in any one change, the combined overhead and profit shall be figured on the basis of the net increase, if any. The amount of credit to be allowed by the Contractor to the City for any such change which results in a net decrease in cost will be the amount of the actual net decrease and a credit in accordance with the markups allowed under the use of the method described in this Paragraph. The Contractor shall not claim for anticipated profits on work that may be omitted. General Conditions 1400-34 8.4 Time Extensions for Change Orders If the Contractor requests a time extension for the extra work necessitated by a proposed Change Order, the request must comply with the applicable requirements within Section 2000, Special Provisions, Paragraph 4.3 Time Impact Analysis. 9.0 PAYMENT 9.1 Scope of Payment 9.1.1 General - The Contractor shall accept the compensation, as herein provided, as full payment for furnishing all labor, materials, tools, equipment, and incidentals necessary for completing the Work according to the Contract Documents, and no additional compensation will be allowed therefor. Neither the payment of any partial payment estimate nor of any retained percentage shall relieve the Contractor of any obligation to make good any defective work or material. 9.1.2 Payment for Patents and Patent Infringement - All fees or claims for any patented invention, article, or arrangement that may be used upon, or in, any manner connected with the performance of the work or any part thereof shall be included in the price bid for doing the work, and the Contractor and its sureties shall defend, protect, and hold the City, its consultants, the City Engineer, together with all their officers, agents, and employees harmless against liability of any nature or kind for any and all costs, legal expenses, and damages made for such fees or claims and against any and all suits and claims brought or made by the holder of any invention or patent, or on account of any patented or unpatented invention, process, article, or appliance manufactured for or used in the performance of the Contract, including its use by the City, unless otherwise specifically stipulated in the Contract. Before final payment is made on the Contract, the Contractor shall furnish an affidavit to the City regarding patent rights for the project. The affidavit shall state that all fees and payments due as a result of the work incorporated into the project or methods utilized during construction have been paid in full. The Contractor shall certify in the affidavit that no other fees or claims exist for work in this project. 9.1.3 Payment of Taxes - The Contractor shall pay and shall assume exclusive liability for all taxes levied or assessed on or in connection with the Contractor's performance of this Contract, including, but not limited to, State and local sales and use taxes, Federal and State payroll taxes or assessments, and excise taxes, and no separate allowance will be made therefor, and all costs in connection therewith shall be included in the total amount of the Contract price. 9.1.4 Payment for Labor and Materials - The Contractor shall pay and require its subcontractors to pay any and all accounts for labor including worker's compensation premiums, state unemployment and federal social security payments and other wage and salary deductions required by law. The Contractor also shall pay and cause its subcontractors to pay any and all accounts for services, equipment, and materials used by the Contractor and its subcontractors during the performance of work under this Contract. Such accounts shall be paid as they become due and payable. If requested by the City, the Contractor shall furnish proof of payment of such accounts to the City. General Conditions 1400-35 9.2 Partial Payments In consideration of the faithful performance of the work prosecuted in accordance with the provisions of these Specifications and the Contract, the City will pay the Contractor for all such work installed on the basis of percentage completion. Payments will be made by the City to the Contractor on estimates duly certified and approved by the City Engineer, based on the value of equipment installed and tested, labor and materials incorporated into said permanent work by the Contractor during the preceding month. Payments will not be made for temporary construction unless specifically provided for in the Contract Documents. Partial payments will be made monthly based on work accomplished as of a day mutually agreed to by the City and the Contractor. The Contractor shall submit his estimate of the work completed during the prior month and the work completed to date in a format corresponding to the accepted cost breakdown. The City Engineer shall review the submitted estimate, and upon approval, the Contractor may submit a detailed invoice for those amounts approved by the City Engineer. If requested, the Contractor shall provide such additional data as may be reasonably required to support the partial payment request. If the City Engineer does not agree with the Contractor's estimate of amount earned, the partial payment request will be returned for revision. The City Engineer will be available to meet to discuss the partial payment request prior to its re-submittal. When the Contractor's estimate of amount earned conforms with the City Engineer's evaluation, the City Engineer will calculate the amount due the Contractor, prepare the progress payment request for signature by the Contractor, and submit the recommended progress payment request for the City's approval and processing. Payment will be made by the City to the Contractor in accordance with City's normal accounts payable procedures; the City shall retain amounts in accordance with Paragraph 1400-9.4, Right to Withhold Amounts. No such estimate or payment shall be required to be made, when in the judgement of the City Engineer, the Work is not proceeding in accordance with the provisions of the Contract, or when in the City Engineer's judgement, the total value of the Work done since the last estimate amounts to less than One Thousand Dollars ($1,000.00). 9.3 Partial Payments - Inclusion of Materials on Hand No payment will be made for materials delivered to the site that are not yet incorporated into the work. General Conditions 1400-36 9.4 Right to Withhold Amounts 9.4.1 Retention - The City will deduct from each partial payment and retain as part security, five (5) percent of the amount earned until the final payment. Pursuant to Public Contract Code Section 22300, for monies earned by the Contractor and withheld by the City to ensure the performance of the Contract, the Contractor, may, at his or her option, choose to substitute securities meeting the requirements of said Section 22300. In the event the Contractor desires to choose this option, the Contractor shall enter into an escrow agreement with the City, and the escrow agent, a qualified bank to be chosen by City, in the form of the contract included in the project specifications. The costs of such escrow shall be paid by the Contractor. The securities to be deposited in said escrow account shall be equivalent, in fair market value, to the amount to be withheld as performance retention. The securities shall be held in accordance with the provisions of Public Contract Code Section 22300, and the implementing contract. Contractor shall have the obligation of ensuring that such securities deposited are sufficient so as to maintain, in total fair market value, an amount equal to the cash amount of the sums to be withheld under the Contract. If, upon written notice from the City, or from the appropriate escrow agent, indicating that the fair market value of the securities has dropped below the dollar amount of monies to be withheld by the City to ensure performance, Contractor shall, within five days of the date of such notice, post additional securities as necessary to ensure that the total fair market value of all such securities held by the City, or in escrow, is equivalent to the amount of money to be withheld by the City under the Contract. Any Contractor that desires to exercise this option shall give notice in writing to City and shall thereafter execute the escrow agreement form provided in Appendix A of these Specifications. 9.4.2 Other Withholds - In addition to the amount which the City may otherwise retain under the Contract, the City may withhold a sufficient amount or amounts of any payment or payments otherwise due the Contractor, as in its judgement may be necessary to cover: a. Payments which may be past due and payable for just claims against the Contractor or any subcontractor for labor or materials furnished for the performance of this Contract. b. For defective work not remedied. c. For failure of the Contractor to make proper payments to its subcontractors or suppliers. d. A reasonable doubt that the Contract can be completed for the balance then unpaid. e. Damage to another Contractor or third party, or to property. General Conditions 1400-37 f. Failure of the Contractor to keep its work progressing in accordance with its progress schedule or maintaining current "As-Built" record drawings. g. The City's costs for the Contractor's failure to complete within the allowed time. h. Cost of insurance arranged by the City due to cancellation or reduction of the Contractor's insurance. i. Failure of the Contractor to make proper submissions, as herein specified. j. Failure to submit, revise, resubmit, or otherwise conform to the requirements herein for preparing and maintaining a construction schedule. k. Payments due the City from the Contractor. l. Reduction of Contract Amount because of modifications. m. The Contractor's neglect or unsatisfactory prosecution of the work including failure to clean up. n. Provisions of law that enable or require the City to withhold such payments in whole or in part. When the above reasons for withhold amounts are removed, payment may be made to the Contractor for amounts withheld. The City in its discretion may apply any withheld amount or amounts to the payment of valid claims. In so doing, the City shall be deemed the agent of the Contractor, and any payment so made by the City shall be considered as a payment made under the Contract by the City to the Contractor, and the City shall not be liable to the Contractor for such payment made in good faith. Such payments may be made without prior judicial determination of the claim or claims. The City will render to the Contractor a proper accounting of such funds disbursed in behalf of the Contractor. 9.5 Substantial Completion When the Contractor considers that the Work is substantially complete, the Contractor shall notify the City Engineer in writing. Upon receipt of the notification, the City and/or its authorized representatives will make inspection, to determine if the Work is sufficiently complete in accordance with the Contract Documents so the City can occupy or utilize the Work for its intended use. If items are found which prevent such use or occupancy, the City Engineer shall notify the Contractor in writing of such items. Upon the completion of such corrective work, the Contractor shall so notify the City Engineer in writing. The City Engineer shall inspect the Work to determine its acceptability for Substantial Completion and for determination of other items which do not meet the terms of the Contract. Upon verification that the project is substantially complete the City Engineer shall prepare a Certificate of Substantial Completion. General Conditions 1400-38 The Certificate shall establish the date of Substantial Completion and the responsibilities of the City and Contractor for security, maintenance, heat, utilities, damage to the Work and insurance, and shall fix the time, not to exceed 60 days, within which the Contractor shall finish all items on the punch list accompanying the Certificate. When the preceding provisions have been approved by both the City and the Contractor, they shall sign the Certificate to acknowledge their written acceptance of the responsibilities assigned to them in such Certificate. By such acknowledgment, the Contractor agrees to pay the City's actual costs including, but not limited to, charges for engineering, inspection and administration incurred due to the failure to complete the punch list within the time period provided in the Certificate of Substantial Completion. 9.6 Final Inspection and Payment Upon completion of the Work, and upon completion of final cleaning, the Contractor shall so notify the City Engineer in writing. Upon receipt of the notification, the City and/or its authorized representatives, will make the final inspection, to determine the actual status of the Work in accordance with the terms of the Contract. If materials, equipment, or workmanship are found which do not meet the terms of the Contract, the City Engineer shall prepare a punch list of such items and submit it to the Contractor. Following completion of the corrective work by the Contractor, the City Engineer shall notify the City that the Work has been completed in accordance with the Contract. Final determination of the acceptability of the Work shall be made by the City. After completion of the work, but prior to its acceptance by the City, the last partial payment will be made to the Contractor in accordance with Paragraph 1400-9.2, Partial Payments. After receipt of the last partial payment, but prior to acceptance of the Work by the City, the Contractor shall send a letter to the City Engineer. The letter, pursuant to California Public Contract Code Section 7100, shall state that acceptance of the final payment described below shall operate as and shall be, a release to the City, its consultants, the City Engineer, and their duly authorized agents, from all claim of and/or liability to the Contract arising by virtue of the Contract related to those amounts. Disputed Contract claims in stated amounts previously filed as provided in Paragraph 1400-7.3.2, Claims, may be specifically excluded by the Contractor from the operation of the release. Following receipt of all required Submittals and the City Engineer's written statement that construction is complete and recommendation that the City accept the project, the City will take formal action on acceptance. Within ten (10) days of the acceptance by the City of the completed work embraced in the Contract, the City will cause to be recorded in the office of the County Recorder a Notice of Completion. After thirty-five (35) days after recording Notice of Completion of the work involved in the Contract, the City will pay the Contractor in lawful money such sums of money as may be due the Contractor including all sums retained but excluding such sums as have previously been paid the Contractor. This payment will constitute the final payment to the Contractor under this Contract. General Conditions 1400-39 9.7 Warranty of Title No material, supplies, or equipment for the work under this Contract shall be purchased subject to any chattel mortgage, security agreement, or under a conditional sale or other agreement by which an interest therein or any part thereof is retained by the seller or supplier. The Contractor warrants good title to all material, supplies, and equipment installed or incorporated in the work and agrees upon completion of all work to deliver the premises, together with all improvements and appurtenances constructed or placed thereon by the Contractor, free from any claim, liens, security interest, or charges, and further agrees that neither the Contractor nor any person, firm, or corporation furnishing any materials or labor for any work covered by this Contract shall have any right to a lien upon the premises or any improvement or appurtenances thereon.

Bidders are required to visit the site and verify existing conditions. Make adjustments and allowances for all necessary equipment to complete all parts of the required work. 1.4 Drawings of Record Provide and keep up-to-date, a complete record set of blue line prints. Correct these prints daily and show every change from the original drawings. Keep this set of prints on the job site and use only as a record set. Special Provisions 3000-2 Do not construe this as authorization to make changes in the layout without definite instruction in each case. Incorporate all changes as noted on the record set of prints thereon with black ink in a neat, legible, understandable and professional manner. Deliver this set to the City upon completion and acceptance of work. 1.5 Cooperation with Other Contractors Section 7-7 of the Standard Specifications is amended by the addition of the following provisions: Should the Contractor foresee any interference or believe project delays or problems might occur due to any action of any other contractor, or if the Contractor determines his own work may cause a delay to the work of the other contractors, the Contractor shall bring this to the attention of the Engineer as soon as possible so that the potential problems or delays may be worked out before problems arise. It is the intention of these Specifications that the Contractor shall cooperate as needed to affect this purpose, and shall be prepared to make short delays, to redeploy its work force to other parts of the work or project, to temporarily reschedule work, and take other reasonable actions to minimize interference and maximize cooperation with all other parties working within the project area. If the Contractor maintains that he is unable to reasonably cooperate with others, then the Contractor shall be prepared to verify to the satisfaction of the Engineer that there are no reasonable actions which he could take to cooperate with others, and that if he did, such actions would cause serious financial harm or unreasonable delay to the Contractor. If the Engineer finds that such evidence is unsatisfactory, the Engineer may order the Contractor to take whatever reasonable actions the Engineer determines are necessary to provide the needed cooperation in order to meet the intent of these Specifications. The contractor shall have no claim for extra compensation for any delay or costs if his work is held up, delayed or interrupted by the City’s having to order cooperative work measures or schedule priorities as outlined above. An extension of contract time shall be the only compensation granted. 1.6 Time Allowed for Construction In accordance with the provisions of Paragraph 1400-6.2, Time of Completion, this project shall be completed within 120 working days from the date specified in the Notice to Proceed. 2.0 BID ITEMS The bid items presented in the bidders schedule are intended to indicate major categories of the work for purposes of comparative bid analysis and payment breakdown for monthly progress payments.

Special Provisions 3000-3 Those items for which there is no estimated quantity and/or specific pay item shall be completed in workmanship like manner to the satisfaction of the City Engineer. Work that is specified for which there is no bid item shall be considered incidental to work associated with bid items; therefore, the payment for these items shall be considered included in the various items of work for which a specific bid item has been provided. The bid items shown in the bidders schedule with "F" designates a final pay quantity. Quantity of any bid item in excess of the final pay quantity shown on the bidder's schedule estimated by the City Engineer will not be paid for. The final pay quantity can only be adjusted to reflect any change orders, extra work, or additional work authorized by the City Engineer. 3.0 MATERIALS 3.1 General Whenever a material, article or piece of equipment is identified on the drawings or specified by reference to brand name or catalog number, it shall be understood that this is referenced for the purpose of defining the performance or other salient requirements and that other products of equal capacities, quality and function shall be considered. 3.2 Substitutions The Contractor may recommend the substitution of a material, article, or piece of equipment of equal substance and function for those referred to in the Contract Documents by reference to the brand name or catalog number and, if in the opinion of the City Engineer, such material, article, or piece of equipment is of equal substance and function to that specified, the City Engineer may approve its substitution and use by the Contractor. Any cost differential shall be deductible from the Contract Price and the Contract Documents shall be appropriately modified by Change Order. The Contractor warrants that if substitutes are approved, no major changes in the function or general design of the project will result. Incidental changes or extra component parts required to accommodate substitute will be made by the Contractor without a change in the Contract Price or Contract time. 3.3 Storage Materials and equipment shall be so stored as not to create a public nuisance and to insure the preservation of their quality and fitness for the work. 4.0 WORK DETAILS 4.1 Traffic Control The Contractor shall provide a traffic control plan, signed by a PE or TE, for acceptance by the City no later than five (5) working days after issuance of the Notice of Award. Subsequently, comments and corrections shall be returned to the Contractor within ten (10) working days.

The 2014 CAMUTCD shall take precedence over the plans, and the plans shall take precedence over the “Standard Specifications.” Traffic control and the traffic plan shall conform to the following: a. The traffic control plan shall indicate the traffic control requirements for the different types of work to be performed. The Contractor shall be responsible for the preparation of plans as necessary for specific items of work. These plans shall be approved by the City Engineer prior to the Contractor commencing any work. b. All traffic controls and safety devices, equipment and materials, including but not limited to, cones, delineators, flashing warning lights, barricades, high level warning devices (flag trees), flags, signs, makers, portable barriers, flashing arrow signs, electronic changeable message signs and markings shall be provided and maintained in “like new” condition. c. The Contractor shall furnish and properly install, construct, erect, use, and continuously inspect and maintain, twenty-four (24) hours per day, seven (7) days a week, all said devices, equipment and materials and all temporary and permanent pedestrian and driving surfaces as necessary to provide for the safety and convenience of, and to properly warn, guide, control, regulate, channelize, and protect the vehicular traffic, pedestrian traffic, project workers, and the public throughout the entire limits of the work activity and beyond said limits as necessary to include area affecting or affected by the work, from the start of work to the completion of the work. d. High-level warning devices (flag trees) are required at all times for any work being performed within the roadway unless otherwise specifically authorized by the City Engineer. e. All barricades shall be equipped with flashing warning lights, and all traffic cones shall be no less than twenty-eight (28) inches in height, except that shorter cones, twelve (12) inches high or higher, may be used during striping maintenance operations where the only function of the cones is to protect the wet paint from the traffic. Special Provisions 3000-5 f. Except as otherwise directed, as shown in the approved traffic control plan, and/or authorized by the City Engineer, two-way vehicular traffic shall be maintained at all times within a minimum of two, 12-foot-wide lanes. At no time shall the Contractor be allowed to reduce the traveled way to one-way vehicular traffic. No reduction of the traveled way width shall be permitted between the hours of 8:30 a.m. and 3:30 p.m., unless otherwise shown in the approved traffic control plans, or prior authorization to do so is granted by the City Engineer. No lane closures shall be permitted or allowed on any City street before 8:30 a.m. and after 3:30 p.m., unless otherwise shown in the approved traffic control plans, or unless authorization to do so is granted by the City Engineer. No reduction of traveled way width shall be permitted on any City street before 8:30 a.m. or after 3:30 p.m., on weekends or holidays, or when active work is not being done, unless otherwise shown in the approved traffic control plans, or unless prior authorization to do so is granted by the City Engineer. Except as shown in the approved traffic control plans, if traffic lanes are not kept open for public use on the days, at the times, and in the manner specified, damage will be sustained by the City and its residents. Since it is and will be impracticable to determine the actual damage which the City and its residents will sustain by reason of Contractor’s failure to comply with the special provisions outlined herein, the City and Contractor agree that Contractor will pay to the City the sum of $200 per hour for each and every hour that any traffic lane is not kept open for public use as required by these special provisions, not as a penalty, but as predetermined liquidated damages.

Filter shall be: Description: The Netafim Sandstorm™ media filter is an automatic self-cleaning filter using silica to achieve high filtration efficiency. The Filter arrives disassembled due to the multiple components. The filter is available with filtration grades (mesh or micron rating) of 120 mesh / 125micron or 150 mesh / 100micron. The Filter can consist of two 30” units; the size has been based on the design flow rates. Technical Specifications 4000-56 Construction: Sandstorm filters have inlet and outlet manifolds with grooved connection ends but can be ordered with a groove to flange adaptor for all inlet/outlet and backflush manifolds. The tanks and manifolds are constructed from high quality mild steel capable of continuous static pressure of 115psi. Tanks and manifolds are covered by high quality epoxy (polyester) coating for rust resistance. The backflush valves are made from steel and covered in epoxy (polyester) for rust resistance. Each backflush valve shall have a normally closed solenoid installed to its bonnet or on a common rail as per customer specification. Operation: The filter shall be capable of filtering suspended particles from water. The maximum operating pressure of the filter is 115psi. The minimum pressure required for backflush will be 30 psi during backflush. The minimum flow required depends on the specific unit size and configuration. The filter shall clean itself automatically when a pressure differential (PD) gauge triggers a backflush controller to initiate a backflush or when the programmed time requirement is met, per backflush controller setup. The optimum setting for the PD gauge is 7 psi. The backflush controller will transmit an electric pulse to the 24-volt solenoid that will command the backflush valves to change from filtration mode to backflush mode. During backflush, the tank being cleaned backflush valve will open to atmosphere in the backflush manifold allowing clean water from the other units to lift the media into suspension and floating debris out the backflush port of the valve. Essentially during backflush, the direction of flow is changed from top inlet manifold (filtration mode) to bottom outlet (backflush mode). The flushing time shall be 90 seconds or longer depending on debris level. During flush, filtered water will continue to be supplied downstream of the filter. The filters will flush one at a time sequentially. Warranty – Contractor shall contact Netafim regarding the inspection process to procure the maximum warranty allowed for the filtration system; the cost of the inspection process is to be factored into the overall cost of the system.
