Award and execution of Contract will be as provided for in the Specifications, Instruction to Bidders, or Notice Inviting Bids. 2-2 ASSIGNMENT. No Contract or portion thereof may be assigned without consent of the Board, except that the Contractor may assign money due or which will accrue to it under the Contract. If given written notice, such assignment will be recognized by the Board to the extent permitted by law. Any assignment of money shall be subject to all proper withholdings in favor of the Agency and to all deductions provided for in the Contract. All money withheld, whether assigned or not, shall be subject to being used by the Agency for completion of the Work, should the Contractor be in default. 2-3 SUBCONTRACTS. 2-3.1 General. Each Bidder shall comply with the Chapter of the Public Contract Code including Sections 4100 through 4113. The following excerpts or summaries of some of the requirements of this Chapter are included below for information: The Bidder shall set forth in the Bid, as provided in 4104: "(a) The name and location of the place of business of each subcontractor who will perform work or labor or render service to the prime contractor in or about the construction of the work or improvements, or a subcontractor licensed by the State of California who, under subcontract to the 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 1 percent of the prime contractor's total bid, or, in the case of bids or offers for the construction of streets or highways, including bridges, in excess of one-half of 1 percent of the prime contractor's total bid or ten thousand dollars ($10,000), whichever is greater." "(b) The portion of the work which will be done by each such subcontractor under this act. The prime contractor shall list only one subcontractor for each such portion as is defined by the prime contractor in his bid." If the Contractor fails to specify a Subcontractor, or specifies more than one Subcontractor for the same portion of the work to be performed under the Contract (in excess of one-half of 1 percent of the Contractor's total Bid), the Contractor shall be qualified to perform that portion itself, and shall perform that portion itself, except as otherwise provided in the Code. As provided in Section 4107, no Contractor whose Bid is accepted shall substitute any person as Subcontractor in place of the Subcontractor listed in the original Bid, except for causes and by procedures established in Section 4107.5. This section provides procedures to correct a clerical error in the listing of a Subcontractor. Section 411 0 provides that a Contractor violating any of the provisions of the Chapter violates the Contract and the Board may exercise the option either to cancel the Contract or assess the Contractor a penalty in an amount of not more than 10 percent of the subcontract involved, after a public hearing. Should the Contractor fail to adhere to the provisions requiring the Contractor to complete 50 percent of the contract price with its own organization, the Agency may at its sole discretion elect to cancel the contract or deduct an amount equal to 10 percent of the value of the work performed in excess of 50 percent of the contract price by other than the Contractor's own organization. The o Revised 1/3013 Contract No. PWS13-40UTIL Page 65 of 172 Board shall be the sole body for determination of a violation of these provisions.

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 Agency, may be granted by the Engineer. Nothing herein shall be construed as granting a right to the Contractor to demand acceptance of such changes. 3-1.2 Payment for Changes Requested by the Contractor. If such changes are granted, they shall be made at a reduction in cost or no additional cost to the Agency. 3-2 CHANGES INITIATED BY THE AGENCY. 3-2.1 General. The Agency may change the Plans, Specifications, character of the work, or quantity of work provided the total arithmetic dollar value of all such changes, both additive and deductive, does not exceed 25 percent of the Contract Price. Should it become necessary to exceed this limitation, the change shall be by written Supplemental Agreement between the Contractor and Agency, unless both parties agree to proceed with the change by Change Order. Change Orders shall be in writing and state the dollar value of the change or established method of payment, any adjustment in contract time of completion, and when negotiated prices are involved, shall provide for the Contractor's signature indicating acceptance. 3-2.2 Payment. 3-2.2.1 Contract Unit Prices. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does not involve substantial change in character of the work from that shown on the Plans or specified in the Specifications, then an adjustment in payment will be made. This adjustment will be based upon the increase or decrease in quantity and the Contract Unit Price. If the actual quantity of an item of work covered by a Contract Unit Price and constructed in conformance with the Plans and Specifications varies from the Bid quantity by 50 percent or less, payment will be made at the Contract Unit Price. If the actual quantity of said item of work varies from the Bid quantity by more than 50 percent, payment will be made per Section 3-2.2.2 or 3-2.2.3 as appropriate. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does involve a substantial change in the character of the work from that shown on the Plans or specified in the Specifications, an adjustment in payment will be made per Section 3-2.4. 3-2.2.2 Increases of More Than 50 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price and constructed in conformance with the Plans and Specifications, exceed the Bid quantity by more than 50 percent, payment for the quantity in excess of 150 percent of the Bid quantity will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3. The Extra Work per Section 3-3, basis of payment, shall not include fixed costs. Fixed costs shall be deemed to have been recovered by the Contractor through payment for 150 percent of the Bid quantity at the Contract Unit Price. o Revised 1/3013 Contract No. PWS13-40UTIL Page 79 of 172 3-2.2.3 Decreases of More Than 50 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price, and constructed in conformance with the Plans and Specifications, be less than 50 percent of the Bid quantity, an adjustment in payment will not be made unless so requested in writing by the Contractor. If the Contractor so requests, payment will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3; however, in no case will payment be less than would be made for the actual quantity at the Contract Unit Price nor more than would be made for 50 percent of the Bid quantity at the Contract Unit Price. 3-2.3 Stipulated Unit Prices. Stipulated Unit Prices are unit prices established by the Agency in the Contract Documents as distinguished from Contract Unit Prices submitted by the Contractor. Stipulated Unit Prices may be used for the adjustment of Contract changes when so specified in the Special Provisions. 3-2.4 Agreed Prices. Agreed Prices are prices for new or unforeseen work, or adjustments in Contract Unit Prices per Section 3-2.2, established by mutual agreement between the Contractor and the Agency. If mutual agreement cannot be reached, the Engineer may direct the Contractor to proceed on the basis of Extra Work in accordance per Section 3-3, except as otherwise specified in Sections 3- 2.2.2 and 3-2.2.3. 3.2.4.1 Schedule of Values. Prior to construction, Contractor shall provide a schedule of values for all lump sum bid items that shall be used for the purpose of progress payments. The prices shall be valid for the purpose of change orders to the project. 3.2.5 Eliminated Items. Should any Bid item be eliminated in its entirety, payment will be made to the Contractor for its actual costs incurred in connection with the eliminated item prior to notification in writing from the Engineer so stating its elimination. If material conforming to the Plans and~ Specifications is ordered by the Contractor for use in the eliminated item prior to the date of......,/ notification of elimination by the Engineer, and if the order for that material cannot be canceled, payment will be made to the Contractor for the actual cost of the material. In this case, the material shall become the property of the Agency. Payment will be made to the Contractor for its actual costs for any further handling. If the material is returnable, the material shall be returned and payment will be made to the Contractor for the actual cost of charges made by the supplier for returning the material and for handling by the Contractor. Actual costs, as used herein, shall be computed on the basis of Extra Work per Section 3-3. 3.2.6 Additive Bid Items. Are not subject to Sections 3-2.2, 3-2.2.3 and 3.2.5 above. No payment will be required for Additive Bid Items if the item is eliminated from the contract.

The use of a labor classification which would increase the extra work cost will not be permitted unless the Contractor establishes the necessity for such additional costs. Labor costs for equipment operators and helpers shall be reported only when such costs are not included in the invoice for equipment rental. The labor cost for foremen shall be proportioned to all of their assigned work and only that applicable to extra work will be paid. Nondirect labor costs, including superintendence, shall be considered part of the markup of Section 3-3.2.3 (a). (b) Materials. The cost of materials reported shall be at invoice or lowest current price at which such materials are locally available and delivered to the job site in the quantities involved, plus sales tax, freight, and delivery. The Agency reserves the right to approve materials and sources of supply, or to supply materials to the Contractor if necessary for the progress of the Work. No markup shall be applied to any material provided by the Agency. (c) Tool and Equipment Rental. No payment will be made for the use of tools which have a replacement value of $200 or less. Regardless of ownership, the rates and right-of-way delay factors to be used in determining rental and delay costs shall be the edition of the, "Labor Surcharge and Equipment Rental Rates" published by CAL TRANS, current at the time of the actual use of the tool or equipment. The right-of-way delay factors therein shall be used as multipliers of the rental rates for determining the value of costs for delay to the Contractor and subcontractors, if any. The labor surcharge rates published therein are not a part of this contract. The rental rates paid shall include the cost of fuel, oil, lubrication, supplies, small tools, necessary attachments, repairs and maintenance of any kind, depreciation, storage, insurance, and all incidentals. Necessary loading and transportation costs for equipment used on the extra work shall be included. If equipment is used intermittently and, when not in use, could be returned to its rental source at less expense to the Agency than holding it at the Work site, it shall be returned, unless the Contractor elects to keep it at the Work site, at no expense to the Agency. All equipment shall be acceptable to the Engineer, in good working condition, and suitable for the purpose for which it is to be used. Manufacturer's ratings and approved modifications shall be used to classify equipment and it shall be powered by a unit of at least the minimum rating recommended by the manufacturer. The reported rental time for equipment already at the Work site shall be the duration of its use on the extra work. This time begins when equipment is first put into actual operation on the extra work, plus the time required to move it from its previous site and back, or to a closer site. (d) Other Items. The Agency may authorize other items which may be required on the extra work, including labor, services, material, and equipment. These items must be different in their nature from those required for the Work, and be of a type not ordinarily available from the Contractor or Subcontractors. Invoices covering all such items in detail shall be submitted with the request for payment. (e) Invoices. Vendors' invoices for material, equipment rental and other expenditures shall be o Revised 1/3013 Contract No. PWS13-40UTIL Page 81 of 172 submitted with the request for payment.

The following percentages shall be added to the Contractor's costs and shall constitute the markup for all overhead and profits: 1) Labor .................................... 20 2) Materials ............................... 15 3) Equipment Rental ................... 15 4) Other Items and Expenditures ... 15 To the sum of the costs and markups provided for in this section, 1 percent shall be added as compensation for bonding. (b) Work by Subcontractor. When all or any part of the extra work is performed by a Subcontractor, the markup established in Section 3-3.2.3(a) shall be applied to the Subcontractor's actual cost of such work. A markup of 10 percent on the first $5,000 of the subcontracted portion of the extra work and a markup of 5 percent on work added in excess of $5,000 of the subcontracted portion of the extra work may be added by the Contractor. 3-3.3 Daily Reports by Contractor. When the price for the extra work cannot be agreed upon, the Contractor shall submit a daily report to the Engineer on forms approved by the Agency. Included are applicable delivery tickets, listing all labor, materials, and equipment involved for that day, and other services and expenditures when authorized. Payment for extra work will not be made until such time that the Contractor submits completed daily reports and all supporting documents to the Engineer. Failure to submit the daily report by the close of the next working day may waive any rights for that day. An attempt shall be made to reconcile the report daily, and it shall be signed by the Engineer and~ the Contractor. In the event of disagreement, pertinent notes shall be entered by each party to explain .....,.; points which cannot be resolved immediately. Each party shall retain a signed copy of the report.

Material differing from that represented in the Contract which the Contractor believes may~. be hazardous waste, as defined in Section 25117 of the Health and Safety Code that is'...._, required to be removed to a Class I, Class II, or Class Ill disposal site in accordance with provisions of existing law. Revised 1/3013 Contract No. PWS13-40UTIL Page 82 of 172 The Engineer will promptly investigate conditions which appear to be changed conditions. If the Engineer determines that conditions are changed conditions and they will materially affect performance time, the Contractor, upon submitting a written request, will be granted an extension of time subject to the provisions of 6-6. If the Engineer determines that the conditions do not justify an adjustment in compensation, the Contractor will be notified in writing. This notice will also advise the Contractor of its obligation to notify the Engineer in writing if the Contractor disagrees. The Contractor's failure to give notice of changed conditions promptly upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection therewith. The Contractor shall not be entitled to the payment of any additional compensation for any act, or failure to act, by the Engineer, including failure or refusal to issue a change order, or for the happening of any event, thing, occurrence, or other cause, unless the Contractor shall have first given the Engineer due written notice of potential claim as hereinafter specified. Compliance with this section shall not be required as a prerequisite to notice provisions in Section 6-7.3 Contract Time Accounting, nor to any claim that is based on differences in measurement or errors of computation as to contract quantities. The written notice of potential claim for changed conditions shall be submitted by the Contractor to the Engineer upon their discovery and prior to the time that the Contractor performs the work giving rise to the potential claim. The Contractor's failure to give written notice of potential claim for changed conditions to the agency upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection therewith. '-··~·· The Contractor shall provide the City with a written document containing a description of the particular circumstances giving rise to the potential claim, the reasons for which the Contractor believes additional compensation may be due and nature of any and all costs involved within 20 working days of the date of service of the written notice of potential claim for changed conditions.

By: Title: Date: Company Name: The Contractor's estimate of costs may be updated when actual costs are known. The Contractor shall submit substantiation of its actual costs to the Engineer within 20 working days after the affected work is completed. Failure to do so shall be sufficient cause for denial of any claim subsequently filed on the basis of said notice of potential claim. It is the intention of this section that differences between the parties arising under and by virtue of the contract be brought to the attention of the Engineer at the earliest possible time in order that such matters be settled, if possible, or other appropriate action promptly taken. o Revised 1/3013 Contract No. PWS13-40UTIL Page 83 of 172 3-5 DISPUTED WORK. The Contractor shall give the agency written notice of potential claim prior to commencing any disputed work. Failure to give said notice shall constitute a waiver of all claims in connection therewith.

In the interest of safety and public value, whenever credible evidence arises to contradict the test values of materials, the Agency and the Contractor will initiate an immediate and cooperative investigation. Test values of materials are results of the materials' tests, as defined by these Specifications or by the special provisions, required to accept the Work. Credible evidence is process observations or test values gathered using industry accepted practices. A contradiction exists whenever test values or process observations of the same or similar materials are diverse enough such that the work acceptance or performance becomes suspect. The investigation shall allow access to all test results, procedures, and facilities relevant to the disputed work and consider all available information and, when necessary, gather new and additional information in an attempt to determine the validity, the cause, and if necessary, the remedy to the contradiction. If the cooperative investigation reaches any resolution mechanism acceptable to both the Agency and the Contractor, the~ contradiction shall be considered resolved and the cooperative investigation concluded. Whenever the,..._,; cooperative investigation is unable to reach resolution, the investigation may then either conclude without resolution or continue by written notification of one party to the other requesting the implementation of a resolution process by committee. The continuance of the investigation shall be contingent upon recipient's agreement and acknowledged in writing within 3 calendar days after receiving a request. Without acknowledgement, the investigation shall conclude without resolution. The committee shall consist of three State of California Registered Civil Engineers. Within 7 calendar days after the written request notification, the Agency and the Contractor will each select one engineer. Within 14 calendar days of the written request notification, the two selected engineers will select a third engineer. The goal in selection of the third member is to complement the professional experience of the first two engineers. Should the two engineers fail to select the third engineer, the Agency and the Contractor shall each propose 2 engineers to be the third member within 21 calendar days after the written request notification. The first two engineers previously selected shall then select one of the four proposed engineers in a blind draw. The committee shall be a continuance of the cooperative investigation and will re-consider all available information and if necessary gather new and additional information to determine the validity, the cause, and if necessary, the remedy to the contradiction. The committee will focus upon the performance adequacy of the material(s) using standard engineering principles and practices and to ensure public value, the committee may provide engineering recommendations as necessary. Unless o Revised 1/3013 Contract No. PWS13-40UTIL Page 90 of 172 otherwise agreed, the committee will have 30 calendar days from its formation to complete their review and submit their findings. The final resolution of the committee shall be by majority opinion, in writing, stamped and signed. Should the final resolution not be unanimous, the dissenter may attach a written, stamped, and signed minority opinion. Once started, the resolution process by committee shall continue to full conclusion unless: 1. Within 7 days of the formation of the committee, the Agency and the Contractor reach an acceptable resolution mechanism; or 2. Within 14 days of the formation of the committee, the initiating party withdraws its written notification and agrees to bear all investigative related costs thus far incurred; or 3. At any point by the mutual agreement of the Agency and the Contractor. Unless otherwise agreed, the Contractor shall bear and maintain a record for all the investigative costs until resolution. Should the investigation discover assignable causes for the contradiction, the assignable party, the Agency or the Contractor, shall bear all costs associated with the investigation. Should assignable causes for the contradiction ex-tended to both parties, the investigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation substantiate a contradiction without assignable cause, the investigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation be unable to substantiate a contradiction, the initiator of the investigation shall bear all investigative costs. All claim notification requirements of the contract pertaining to the contradiction shall be suspended until the investigation is concluded. 4-2 MATERIALS TRANSPORTATION, HANDLING AND STORAGE. The Contractor shall order, purchase, transport, coordinate delivery, accept delivery, confirm the quantity and quality received, prepare storage area(s), store, handle, protect, move, relocate, remove and dispose excess of all materials used to accomplish the Work.

CONTRACTOR'S CONSTRUCTION SCHEDULER The Contractor is required to employ or retain the services of a Construction Scheduler. The Construction Scheduler shall have at least five (5) years of verifiable experience as the person primarily responsible for preparing and maintaining detailed project schedules on projects of the same or similar size and nature as this project. The Construction Scheduler is required to attend all meetings pertaining to scheduling and progress of the work. If the Construction Scheduler leaves the employ of the Contractor, the Contractor will be required to fulfill the requirements of the following paragraph within thirty (30) calendar days. Within five (5) days after Notice of Award the Contractor shall provide a statement to the Engineer with the following: a. Identification, qualifications and experience of the Contractor's Construction Scheduler and all other members of the Contractor's scheduling staff. b. References of not less than two (2) previous projects on which the Contractor's Construction Scheduler has utilized CPM scheduling. The Engineer reserves the right to disapprove any candidate proposed for the project. The Engineer reserves the right to remove, without rights to work on the project, any member of the Contractor's scheduling staff that is, in the Engineer's opinion, incompetent in scheduling. GENERAL REQUIREMENTS ~ The Contractor shall be responsible for developing, coordinating and maintaining the schedule. The""'-' Contractor shall submit to the Engineer baseline, monthly update and final update schedules, each consistent in all respects with the time and order of work requirements of the contract. The project work shall be executed in the sequence indicated on the current accepted schedule. The schedule shall reflect the Contractor's plans for and status of the work. Schedules shall show the order in which the Contractor proposes to carry out the work with logical links between time scaled work activities, and calculations made using the critical path method to determine the controlling operation or operations. The Contractor is responsible for assuring that all activity sequences are logical and that each schedule shows a coordinated plan for complete performance of the work. All versions of the Contractor's schedules shall be based solely on the work as awarded, and shall exclude any substitute proposals, even if the Contractor pursues a substitution in accordance with provisions of the contract. The activities included in the schedule shall be analyzed in detail to determine activity time durations in units of project working days. Durations shall be based on the labor (crafts), equipment, and materials required to perform each activity on a normal work day basis. No onsite activity shall have a duration over twenty (20) working days except non-construction activities such as submittals, procurement and delivery of materials or equipment, and concrete curing. All durations shall be the result of definitive manpower and resource planning by the Contractor to perform the work in consideration of contractually defined on-site work conditions. Schedules shall begin with the date of the issuance of the Notice to Proceed, include all constructio~ activities including submittal review, operation checks, final walk-thru, generating punch list and conclude with the date of Final Completion as defined herein. The schedule shall incorporate a o Revised 1/3013 Contract No. PWS13-40UTIL Page 98 of 172 c c minimum of twenty (20) working days for each review by the Engineer of shop drawings and material submittals. The Contractor shall allow adequate time for work performed by the Engineer and others. The Contractor shall allow a minimum of three (3) working days for the Engineer to conduct a thorough walk-through and ten (10) working days for generation of the punch list both inclusive in the contract time allotted. The Contractor shall work diligently to maintain this schedule after the final walk-through by completing all punch list items within twenty (20) working days after being provided the official written punch list by the Engineer. Schedules shall include, but not be limited to, activities that show the following that are applicable to the project: A. Project name, Contractor's name, address and phone number, dates of original schedule and latest revision, revision number and contract time. B. Project characteristics, salient features, or interfaces, including those with outside entities that could affect time of completion. C. Project start date, scheduled completion date and other milestones. D. Work performed by the Contractor, subcontractors and suppliers. E. Work performed by the Engineer and others, including testing, sampling and review time, and work by other agencies. F. Submittal development, delivery, review and approval, including those from the Contractor, subcontractors and suppliers. G. Procurement, fabrication, delivery, installation and testing of materials, plants and equipment for all materials and equipment with lead times exceeding four (4) weeks. H. Testing, curing and settlement periods. I. Utility notification and relocation. J. Erection and removal of falsework and shoring. K. Major traffic stage switches. L. Finishing roadway and final cleanup. M. Identification of any activity requiring unusual shift work, such as two shifts, six (6) day weeks, specified overtime, or work at time other than regular days or hours. Schedules shall have not less than 150 and not more than 1 ,000 activities, unless otherwise authorized by the Engineer. The number of activities shall be sufficient to assure adequate planning and management of the project, so that, in the sole judgment of the Engineer, it provides an appropriate basis to permit monitoring and evaluation of progress, and to do an analysis of time impacts. Schedule activities shall include the following: A. A clear and legible description. B. Early and Actual start and finish dates. C. A duration of not less than one working day, except for event activities, and not more than 20 working days, unless otherwise authorized by the Engineer. D. At least one predecessor and one successor activity, except for project start and finish milestones. E. Required constraints. F. Codes for responsibility, stage, and location. G. Costs, interdependence, critical path and percentage of completion status. o Revised 1/3013 Contract No. PWS13-40UTIL Page 99 of 172 Float for each activity shall be shown on the schedule. Float is the number of days by which each activity within the construction schedule may be delayed from its early completion date without...,.,~ necessarily extending the contract time. Float belongs to the project and is not for the exclusive benefi' , of any party. Float shall be available to the City or the Contractor to accommodate changes in the work or to mitigate the effect of events which may delay performance or completion. Baseline, update and final schedules shall be submitted and reviewed in accordance with Section 5- 1.02 of these special provisions and as specified herein. The Engineer's review and acceptance of schedules shall not waive any contract requirements and shall not relieve the Contractor of any obligation thereunder or responsibility for submitting complete and accurate information. Schedules that are reviewed by the Engineer with a resultant "Amend and Resubmit' or "Rejected/Resubmit' review response shall be corrected by the Contractor and resubmitted to the Engineer within ten (10) working days of notification by the Engineer, at which time a new review period of five (5) working days will begin. The Contractor shall be subject to retention of funds in accordance with "Retention" of these special provisions for failure to submit an approved schedule within the time specified herein. If the Contractor proceeds with the work without an approved schedule, it shall be at his own risk. If the Contractor elects not to proceed with the work, any resulting delay, impact or disruption to the project will be deemed noncompensable. The Engineer may request that the Contractor and all major subcontractors (defined herein as being any subcontractor or supplier with five (5) percent or more of the value of the Contract) participate in review of any schedule submission. Errors or omissions on schedules shall not relieve the Contractor from finishing all work within the time limit specified for completion of the contract. If, after a schedule has been accepted by the Engineer, either the Contractor or the Engineer discovers that any aspect of the schedule has an error or omission, it shall be corrected by the Contractor on the next update schedule. The Engineer may adjust contract working days for ordered changes that affect the schedule~ completion date, in conformance with the provisions in Section 4-1.03, "Changes," of the Standard'-' Specifications. The Contractor shall prepare a time impact analysis to determine the effect of the change in conformance with the provisions in "Time Impact Analysis" specified herein, and shall include the impacts acceptable to the Engineer in the next update schedule. Changes that do not affect the controlling operation on the critical path will not be considered as the basis for a time adjustment. Changes that do affect the controlling operation on the critical path will be considered by the Engineer in decreasing time or granting an extension of time for completion of the contract. Time extensions will only be granted if the total float is absorbed and the scheduled completion date is delayed one or more working days because of the ordered change. The Contractor shall not be entitled to any extension in contract time, or recover for any delay impacts claimed to have been incurred unless the Contractor can demonstrate excusable, compensable delay based upon the critical path evaluation of the project schedule as required by "Time Impact Analysis." Misrepresentations of actual work durations in order to suppress available float time shall be cause for rejection of the schedule and any revisions or updates. SCHEDULING SOFTWARE The schedule shall be prepared in the most recent version of Primavera P3 or Suretrack scheduling software. o Revised 1/3013 Contract No. PWS13-40UTIL Page 100 of 172 C' c CASH FLOW SCHEDULING With the baseline schedule, the Contractor shall also submit a schedule of cash flow to the Engineer. The cash flow schedule shall provide estimates of the amount of each monthly progress payment for the duration of the project. The cash flow schedule shall be updated every six (6) months. The cash flow shall show the net payment requests for each month and the cumulative payment requests to date shall also be shown after deducting retainage and any other monies withheld. The Contractor, at the Preconstruction Scheduling Conference, shall explain in detail the procedure to be used to develop the cash flow schedule. This procedure is subject to the review and approval of the Engineer. NETWORK DIAGRAMS, REPORTS AND DATA The Contractor shall include the following for each schedule submittal: A. Two sets of originally plotted, time-scaled network diagrams. B. Two copies of a narrative report. C. Two copies of the cash flow schedule (updated every six (6) months). D.

Pending items and status thereof: 1. Permits 2. Change orders 3. Time adjustments 4. Non-compliance notices I. Reasons for an early or late scheduled completion date in comparison to the contract completion date. PRE-CONSTRUCTION SCHEDULING CONFERENCE The Contractor shall schedule with the Engineer a pre-construction scheduling conference within 10 working days of the approval and execution of the contract. The Contractor's project manager and construction scheduler should be present. At this meeting the Engineer will review the requirements of this section of the special provisions with the Contractor. The Contractor shall submit a general time-scaled logic diagram displaying the major activities and o Revised 1/3013 Contract No. PWS13-40UTIL Page 101 of 172 sequence of planned operations and shall be prepared to discuss the proposed work plan and schedule methodology that comply with the requirements of these special provisions. If the Contractor proposes ..... -.. deviations to the construction staging of the project, then the general time scaled logic diagram shal' · also display the deviations and resulting time impacts. The Contractor shall be prepared to discuss the proposal. At this meeting, the Contractor shall additionally submit the alphanumeric coding structure and the activity identification system for labeling the work activities. To easily identify relationships, each activity description shall indicate its associated scope or location of work by including such terms as quantity of material, type of work, bridge number, station to station location, side of highway (such as left, right, northbound, southbound), and lane number. The Engineer will review the logic diagram, coding structure, and activity identification system, and provide any required baseline schedule changes to the Contractor for implementation. BASELINE SCHEDULE Beginning the week following the pre-construction scheduling conference, the Contractor shall meet with the Engineer weekly until the baseline schedule is accepted by the Engineer to discuss schedule development and resolve schedule issues. The Contractor shall submit to the Engineer a baseline schedule within 20 working days of approval of the contract. The Contractor shall allow 3 weeks for the Engineer's review after the baseline schedule and all support data are submitted. The baseline schedule shall include the entire scope of work and how the Contractor plans to complete all work contemplated. The baseline schedule shall show the activities that define the critical path. Multiple critical paths and near-critical paths shall be kept to a minimum. A total of not more than srt-\ percent of the baseline schedule activities shall be critical or near critical, unless otherwise authorized'-" by the Engineer. The baseline schedule shall not extend beyond the number of working days specified in these special provisions. The baseline schedule shall have a data date of the first working day of the contract and not include any completed work to date. The baseline schedule shall not attribute negative float or negative lag to any activity. The Contractor shall provide written evidence that all subcontractors have reviewed, and agreed with the schedule with respect to their portion of the work. Should the Contractor propose a project duration shorter than the contract duration, a complete baseline schedule must be submitted, reflecting the shorter duration and in complete accordance with all requirements of this contract. The Engineer may choose to accept the Contractor's proposal of a shorter project duration; provided that the City is satisfied that the shortened baseline schedule is reasonable and the City and all other entities, public and private, which interface with the project are able to support the provisions of the new shortened baseline schedule. The City's acceptance of a shortened duration project will be confirmed through the execution of a contract change order revising the project duration and implementing all contractual requirements, including liquidated damages, in accordance with the revised duration. o Revised 1/3013 Contract No. PWS13-40UTIL Page 102 of 172 UPDATE SCHEDULE The Contractor shall submit an update schedule and meet with the Engineer to review contract progress, on or before the first day of each month, beginning one month after the baseline schedule is accepted. The Contractor shall allow 2 weeks for the Engineer's review after the update schedule and all support data are submitted, except that the review period shall not start until the previous month's schedule is accepted. Update schedules that are not accepted or rejected within the review period will be considered accepted by the Engineer. The update schedule shall have a data date of the twenty-first day of the month or other date established by the Engineer. The update schedule shall show the status of work actually completed to date and the work yet to be performed as planned. Actual activity start dates, percent complete and finish dates shall be shown as applicable. Durations for work that has been completed shall be shown on the update schedule as the work actually occurred, including Engineer submittal review and Contractor resubmittal times. The Contractor may include modifications such as adding or deleting activities or changing activity constraints, durations or logic that do not (1) alter the critical path(s) or near critical path(s) or (2) extend the scheduled completion date compared to that shown on the current accepted schedule. The Contractor shall state in writing the reasons for any changes to planned work. If any proposed changes in planned work will result in (1) or (2) above, then the Contractor shall submit a time impact analysis as described herein. Should the Contractor modify or change the construction schedule for change order work or otherwise, the Engineer shall be notified with an explanation in writing accompanying the updated schedule. If the Engineer questions the logic of the schedule, he may at any time request a detail schedule narrative that describes the approach to the work and the rationale used to develop the schedule relationships and logic. Upon approval of a change order or issuance of a Notice to Proceed with a change, the approved change order shall be reflected in all future schedule updates. Schedule revision costs shall be included in all change orders and shall be limited to a maximum of five (5) percent of the change order total or $200, whichever is less. Should the schedule update indicate a completion or contractually required milestone date later than the properly adjusted contract or milestone duration, the Agency may withhold Liquidated Damages for the number of days late. Should a subsequent "Accepted" Schedule Update remove all or a portion of the delay, all or the allocated portion of the previously held Liquidated Damages shall be released in the monthly payment to the Contractor immediately following the "Accepted Schedule". Should the actual or projected progress of the work become substantially different from that depicted in the schedule, independently of and prior to the next monthly update, the Contractor will submit a revised Baseline Construction Schedule, with a list and explanation of each change made to the schedule. As used in this sub-section "substantially different" means a time variance greater than 5 percent of the number of days of duration for the project. If completion of any part of the work, delivery of equipment or materials, or submittal of Contractor submittals is behind schedule and will impact the completion date of the work, the Contractor shall submit a written recovery plan and schedule update for completing the work by the current contract date. The recovery plan and update schedule shall be submitted within ten (1 0) days and revised until accepted by the Engineer. o Revised 1/3013 Contract No. PWS13-40UTIL Page 103 of 172 TIME IMPACT ANALYSIS The Contractor shall submit a written time impact analysis (TIA) to the Engineer with each request for adjustment of contract time, or when the Contractor or Engineer consider that an approved or anticipated change may impact the critical path or contract progress. The TIA shall illustrate the impacts of each change or delay on the current scheduled completion date or internal milestone, as appropriate. The analysis shall use the accepted schedule that has a data date closest to and prior to the event. If the Engineer determines that the accepted schedule used does not appropriately represent the conditions prior to the event, the accepted schedule shall be updated to the day before the event being analyzed. The TIA shall include an impact schedule developed from incorporating the event into the accepted schedule by adding or deleting activities, or by changing durations or logic of existing activities. If the impact schedule shows that incorporating the event modifies the critical path and scheduled completion date of the accepted schedule, the difference between scheduled completion dates of the two schedules shall be equal to the adjustment of contract time. The Engineer may construct and utilize an appropriate project schedule or other recognized method to determine adjustments in contract time until the Contractor provides the TIA. The Contractor shall submit a TIA in duplicate within 15 working days of receiving a written request for a TIA from the Engineer. The Contractor shall allow the Engineer 2 weeks after receipt to approve or reject the submitted TIA. All approved TIA schedule changes shall be shown on the next update schedule. If a TIA submitted by the Contractor is rejected by the Engineer, the Contractor shall meet with the Engineer to discuss and resolve issues related to the TIA. If agreement is not reached, the Contractor will be allowed 15 days from the meeting with the Engineer to give notice in conformance with the provisions in Section 9-1.04, "Notice of Potential Claim," of the Standard Specifications. The Contracto~. shall only show actual as-built work, not unapproved changes related to the TIA, in subsequent updat~ schedules. If agreement is reached at a later date, approved TIA schedule changes shall be shown on the next update schedule. The Engineer will withhold remaining payment on the schedule contract item if a TIA is requested by the Engineer and not submitted by the Contractor within 15 working days. The schedule item payment will resume on the next estimate after the requested TIA is submitted. No other contract payment will be retained regarding TIA submittals. FINAL UPDATE SCHEDULE The Contractor shall submit a final update, as-built schedule with actual start and finish dates for the activities, within 30 calendar days after completion of contract work. The Contractor shall provide a written certificate with this submittal signed by the Contractor's project manager and an officer of the company stating, "To my knowledge and belief, the enclosed final update schedule reflects the actual start and finish dates of the actual activities for the project contained herein." An officer of the company may delegate in writing the authority to sign the certificate to a responsible manager. o Revised 1/3013 Contract No. PWS13-40UTIL Page 104 of 172 c· RETENTION If the Contractor fails to submit an acceptable schedule conforming to the requirements of these special provisions as determined by the Engineer, the City may retain an amount up to 10 percent of the estimated value of the work performed during each estimate period. Retention for failure to submit an approved schedule shall not exceed $10,000 for the first month and $50,000 for any subsequent month. Schedule retentions will be released for payment on the next monthly estimate for partial payment following the date that acceptable schedules are submitted to the Engineer or as otherwise specified herein. Upon completion of all contract work and approval of the final update schedule and certification, any remaining retained funds associated with this section, "Progress Schedule (Critical Path Method)", will be released "for payment. Retentions held in conformance with this section shall be in addition to other retentions provided for in the contract. No interest will be due the Contractor on retention amounts. PAYMENT Progress schedule (critical path method) will be paid for at a lump sum price. The contract lump sum price paid for progress schedule (critical path method) shall include full compensation for furnishing all labor, material, tools, equipment, and incidentals, and for doing all the work involved in preparing, furnishing, and updating schedules, as specified in the Standard. Specifications and these special provisions, and as directed by the Engineer. Payments for the progress schedule (critical path method) contract itern will be made progressively as follows: A. A total of 25 percent of the item amount or a total of 25 percent of the amount listed for progress schedule (critical path method) in "Payments" of Section 9 of these special provisions, whichever is less, will be paid upon achieving all of the following: 1. Completion of 5 percent of all contract item work. 2. Acceptance of all schedules and TIAs required to the time when 5 percent of all contract item work is complete. B. A total of 50 percent of the item amount or a total of 50 percent of the amount listed for progress schedule (critical path method) in "Payments" of Section 9 of these special provisions, whichever is less, will be paid upon completion of 25 percent of all contract item work and acceptance of all schedules and TIAs required to the time when 25 percent of all contract item work is complete. C. A total of 75 percent of the item amount or a total of 75 percent of the amount listed for progress schedule (critical path method) in "Payments" of Section 9 of these special provisions, whichever is less, will be paid upon completion of 50 percent of all contract item work and acceptance of all schedules and TIAs required to the time when 50 percent of all contract item work is complete. D. A total of 100 percent of the item amount or a total of 100 percent of the amount listed for progress schedule (critical path method) in "Payments" of Section 9 of these special provisions, whichever is less, will be paid upon completion of all contract item work, acceptance of all schedules and TIAs required to the time when all contract item work is complete, and submittal of the certified final update schedule. If the Contractor fails to complete any of the work or provide any of the schedules required by this section, the Engineer shall make an adjustment in compensation in conformance with the provisions in Section 4-1.03C, "Changes in Character of Work," of the Standard Specifications for the work not performed. Adjustments in compensation for schedules will not be made for any increased or decreased work ordered by the Engineer in furnishing schedules. 6-2 PROSECUTION OF WORK. To minimize public inconvenience and possible hazard and to restore street and other work area to /""""' their original condition and state of usefulness as soon as practicable, the Contractor shall diligently \._., prosecute the Work to completion. If the Engineer determines that the Contractor is failing to prosecute the Work to the proper extent, the Contractor shall, upon orders from the Engineer, immediately take steps to remedy the situation. All costs of prosecuting the Work as described herein shall be included o Revised 1/3013 Contract No. PWS13-40UTIL Page 105 of 172 in the Contractor's Bid. Should the Contractor fail to take the necessary steps to fully accomplish said purposes, after orders of the Engineer, the Engineer may suspend the work in whole or part, until the .. Contractor takes said steps. As soon as possible under the prov1s1ons of the Specifications, the Contractor shall backfill all excavations and restore to usefulness all improvements existing prior to the start of the Work. If Work is suspended through no fault of the Agency, all expenses and losses incurred by the Contractor during such suspensions shall be borne by the Contractor. If the Contractor fails to properly provide for public safety, traffic, and protection of the Work during periods of suspension, the Agency may elect to do so, and deduct the cost thereof from monies due the Contractor. Such actions will not relieve the Contractor from liability. 6-2.1 Summary of Work. The work to be done shall consist of furnishing all labor, equipment and materials, and performing all operations necessary to complete the Project Work as shown on the Project Plans and as specified in the Specifications. The major elements of the project include the installation of a prefabricated steel truss bridge across the Agua Hedionda Lagoon Channel, the construction of a 33 MGD sewer lift station, construction of approximately 4000 LF of 36-inch diameter HDPE sewer force main by open cut and trenchless methods, construction of approximately 7000 LF of 54-inch diameter gravity sewer pipe by open cut and microtunneling methods, and construction of approximately 11 ,000 LF of 18-inch and 12-inch diameter PVC recycled water pipeline. Upon completion of the pipeline work, Avenida Encinas between Palomar Airport Road and Cannon Road will receive a 2" grind and asphalt overlay. The project replaces the existing sewer lift station and wood trestle that was constructed in 1964. Most of the existing interceptor sewer pipeline will continue to be utilized and will be paralleled~. with a new sewer to provide increased capacity. The existing sewer lift station will remain in~ operation for the duration of the project until the new lift station and pipelines have been accepted by the City in accordance with the Contract Documents. The lift station is operated and maintained by the Encina Wastewater Authority (EWA) under contract with the City. The Contractor shall protect the existing sewer lift station facility during construction and provide access at all times to maintenance and operations personnel. The City has purchased temporary engine driven bypass pumps to bypass sewage flow around the lift station in an emergency. The pumps are located immediately north of the existing lift station and shall remain in-place until the new lift station is operational, at which time the City will have the pumps removed so that the Contractor can complete the Work. The Contractor has considerable flexibility in the scheduling of its work; however, there are various conditions and restrictions indicated in the Contract Documents that must be included in the Contractor's schedule. Additionally, the portion of the existing interceptor sewer south of Palomar Airport Road has a number of connections from collector sewers. The flow from these collector sewers shall be transferred to the new interceptor by the Contractor as shown on the plans. In addition to the schedule constraints identified in Section 5-6 herein, the Contractor shall complete the open cut pipeline work across NRG and SDGE properties within the first nine (9) months of the project so as not to impact construction activity for the proposed power plant project, known as the Carlsbad Energy Center. Access to the lift station and bridge will be by way of Avenida Encina and requires crossing through the Cannon Substation owned by SDG&E and then through NRG property. The City has acquired easements for the permanent facilities, but it shall be the Contractor's responsibility to enter into right-Jlilll\ of-entry agreements with these agencies to gain construction access. Boilerplate agreements with"'-J these agencies are included in the Appendix for the Contractor's information. "'- 6-2.2 Not Used. Revised 1/3013 Contract No. PWS13-40UTIL Page 106 of 172 c 6-2.3 Project Meetings. The Engineer will establish the time and location of weekly Project Meetings. The Contractor's Representative shall attend each Project Meeting. The Project Representative shall be the individual determined under Section 7-6, "The Contractor's Representative". No separate payment for attendance of the Contractor, the Contractor's Representative or any other employee or subcontractor or subcontractor's employee at these meetings will be made. 6-3 SUSPENSION OF WORK. 6-3.1 General. The Work may be suspended in whole or in part when determined by the Engineer that the suspension is necessary in the interest of the Agency. The Contractor shall comply immediately with any written order of the Engineer. Such suspension shall be without liability to the Contractor on the part of the Agency except as otherwise specified in Section 6-6.3. 6-3.2 Archaeological and Paleontological Discoveries. If discovery is made of items of archaeological or paleontological interest, the Contractor shall immediately cease excavation in the area of discovery and shall not continue until ordered by the Engineer. When resumed, excavation operations within the area of discovery shall be as directed by the Engineer. Discoveries which may be encountered may include, but not be limited to, dwelling sites, stone implements or other artifacts, animal bones, human bones, and fossils. The Contractor shall be entitled to an extension of time and compensation in accordance with the """'~/ provisions of Section 6-6. 6-4 DEFAULT BY CONTRACTOR. If the Contractor fails to begin delivery of material and equipment, to commence the Work within the time specified, to maintain the rate of delivery of material, to execute the Work in the manner and at such locations as specified, or fails to maintain the Work schedule which will insure the Agency's interest, or, if the Contractor is not carrying out the intent of the Contract, the Agency may serve written notice upon the Contractor and the Surety on its Faithful Performance Bond demanding satisfactory compliance with the Contract. The Contract may be canceled by the Board without liability for damage, when in the Board's opinion the Contractor is not complying in good faith, has become insolvent, or has assigned or subcontracted any part of the Work without the Board's consent. In the event of such cancellation, the Contractor will be paid the actual amount due based on Contract Unit Prices or lump sums bid and the quantity of the Work completed at the time of cancellation, less damages caused to the Agency by acts of the Contractor. The Contractor, in having tendered a Bid, shall be deemed to have waived any and all claims for damages because of cancellation of Contract for any such reason. If the Agency declares the Contract canceled for any of the above reasons, written notice to that effect shall be served upon the Surety. The Surety shall, within five (5) days, assume control and perform the Work as successor to the Contractor. If the Surety assumes any part of the Work, it shall take the Contractor's place in all respects for that part, and shall be paid by the Agency for all work performed by it in accordance with the Contract. If the Surety assumes the entire Contract, all money due the Contractor at the time of its default shall be payable to the Surety as the Work progresses, subject to the terms of the Contract. If the Surety does not assume control and perform the Work within 5 days after receiving notice of cancellation, or fails to continue to comply, the Agency may exclude the Surety from the premises. The o Revised 1/3013 Contract No. PWS13-40UTIL Page 107 of 172 Agency may then take possession of all material and equipment and complete the Work by Agency forces, by letting the unfinished Work to another Contractor, or by a combination of such methods. In any event, the cost of completing the Work shall be charged against the Contractor and its Surety and may be deducted from any money due or becoming due from the Agency. If the sums due under the Contract are insufficient for completion, the Contractor or Surety shall pay to the Agency within 5 days after the completion, all costs in excess of the sums due. The provisions of this section shall be in addition to all other rights and remedies available to the Agency under law. 6-5 TERMINATION OF CONTRACT. The Board may terminate the Contract at its own discretion or when conditions encountered during the Work make it impossible or impracticable to proceed, or when the Agency is prevented from proceeding with the Contract by act of God, by law, or by official action of a public authority. 6-6 DELAYS AND EXTENSIONS OF TIME. 6-6.1 General. If delays are caused by unforeseen events beyond the control of the Contractor, such delays will entitle the Contractor to an extension of time as provided herein, but the Contractor will not be entitled to damages or additional payment due to such delays, except as provided in 6-6.3. Such unforeseen events may include: war, government regulations, labor disputes, strikes, fires, floods, adverse weather or elements necessitating cessation of work, inability to obtain materials, labor or equipment, required extra work, or other specific events as may be further described in the Specifications. No extension of time will be granted for a delay caused by the Contractor's inability to obtain materials unless the Contractor furnishes to the Engineer documentary proof. The proof must be provided in a~ timely manner in accordance with the sequence of the Contractor's operations and the approved·.....,; construction schedule. If delays beyond the Contractor's control are caused by events other than those mentioned above, the Engineer may deem an extension of time to be in the best interests of the Agency. The Contractor will not be entitled to damages or additional payment due to such delays, except as provided in Section 6- 6.3. If delays beyond the Contractor's control are caused solely by action or inaction by the Agency, such delays will entitle the Contractor to an extension of time as provided in Section 6-6.2. 6-6.2 Extensions of Time. Extensions of time, when granted, will be based upon the effect of delays to the Work.

The resurfacing work requires the affected streets be closed for one day, usually from around 7:30 a.m. to 5 p.m. If your street is to be resurfaced, you will be notified of the exact day 72 hours in advance by a flyer attached to your front door knob. If it is a street in your neighborhood, you will notice temporary "No Parking" signs on the affected streets with a specific date written on them. (PLEASE NOTE: weather conditions and other factors outside our control can sometimes cause work to be rescheduled at the last minute. If this happens, we will notify you as soon as possible of the new date.) To prepare for this street closure, we are asking neighbors to help. Here's how: • Park your car outside the affected area unless you plan to leave before 7 a.m. the morning the work starts. • If your street is affected, park your car in your driveway or garage (off the street) if you aren't going to need it during these times. Cars left on a street posted "No Parking" will be towed at the owner's expense. • Avoid walking, biking and skateboarding on new roads until construction signs are removed. Please keep kids and pets off the new roadway the day of the resurfacing, too. Until it is dry, the road resurfacing material will stain your shoes, cars, carpets and floors. • During the day of the resurfacing, please try to keep the new road dry (monitor sprinklers, hoses and other water sources around your home). • Work will not affect your trash pickup. Please put trash out on your normal day. • For the next few months, it is even more important to keep your car off resurfaced streets on street sweeping day. Street sweeping helps remove small pebbles and grit from the newly paved roadways. (To see the street sweeping schedule, search "street sweeping" on the city website, www.carlsbadca.gov). (XXXXXXX) will be performing the resurfacing work for the city. You may call them at XXX-XXX-XXXX for more information about the project and to answer questions.
