Agenda packet — Vallejo City Council, October 24, 2023 (part 3 of 4)

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

Unless otherwise approved by the Engineer in writing, Contractor shall submit to Engineer on or before the tenth (10th) day of the month, an itemized application for payment for the cost of the work in permanent place, which has been completed in strict accordance with the Contract Documents as of the last day of the preceding month, less amounts previously paid. The application for payment shall be prepared in a form acceptable to Engineer, and shall contain itemized amounts in accordance with the Contract Documents. The applications for payment shall not include requests for payment on account of changes which have not been authorized by Change Orders, or for amounts Contractor does not intend to pay a subcontractor because of a dispute or other reason.

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

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

Payment of all, or any part, of an application for payment may be withheld, a certificate of payment may be withheld, all or part of a previous certificate for payment may be nullified and that amount withheld from a current certificate for payment, or the City of Vallejo may withhold from payment, on account of any of the following:

Defective work not remedied;
Third-party claims against Contractor or City of Vallejo arising from the acts or omissions of Contractor or subcontractors;
Stop notices;
Failure of Contractor to make timely payments due to subcontractors for material or labor;
A reasonable doubt that the work can be completed for the balance of the Contract price then unpaid;
Damage to the City of Vallejo or others for which Contractor is responsible; Reasonable evidence that the work cannot be completed within the Contract time, and the unpaid balance of the Contract price would not be adequate to complete the work and cover City of Vallejo's damages for the anticipated delay; Failure of Contractor to maintain, update, and submit record documents; Failure of Contractor to submit schedules or their updates as required by the Contract Documents;
Performance of the work by Contractor without properly processed shop drawings; Liquidated damages assessed;

By resolution of the City of Vallejo’s City Council, a fund has been established, money appropriated in the current budget, and assigned to the account(s) which is/are the sole source(s) of funds available for payment of the Contract price. Contractor understands and agrees that Contractor will be paid only from this special fund and if for any reason this fund is not sufficient to pay Contractor, Contractor will not be entitled to payment.

The availability of money in this fund, and City of Vallejo's ability to draw from this fund, are conditions precedent to City of Vallejo's obligation to make payments to Contractor.

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

9-1.065 PAYMENT OF WITHHELD FUNDS

Upon the Contractor's request, the City of Vallejo will make payment of funds withheld from progress payments to ensure performance of the Contract if the Contractor deposits in escrow with the City of Vallejo, or with a bank acceptable to the City of Vallejo, securities equivalent to the amount withheld. The Contractor shall be beneficial owner of any securities substituted for moneys withheld and shall receive any interest thereon.

Upon satisfactory completion of the Contract, the securities shall be returned to the Contractor.

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

Upon satisfactory completion of the Contract, the Contractor shall receive from the escrow agent all securities, interest and payments received by the escrow agent from the City of Vallejo.

Alternatively, and subject to the acceptance by the City of Vallejo, the payment of retentions earned may be deposited directly with a person licensed under Division 6 (commencing with Section 17000) of the Financial Code as the escrow agent. Upon written request of an escrow agent that has not been approved by the City of Vallejo under subdivision (c) of Section 10263 of the Public Contract Code, the City of Vallejo will provide written notice to that escrow agent within 10 business days of receipt of the request indicating the reason or reasons for not approving that escrow agent. The payments will be deposited in a trust account with a Federally chartered bank or savings association within 24 hours of receipt by the escrow agent. The Contractor shall not place any retentions with the escrow agent in excess of the coverage provided to that escrow agent pursuant to subdivision (b) of Section 17314 of the Financial Code. In all respects not inconsistent with subdivision (c) of Section 10263 of the Public Contract Code, the remaining provisions of Section 10263 of the Public Contract Code shall apply to escrow agents acting pursuant to subdivision (c) of Section 10263 of the Public Contract Code.

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

The Contractor shall obtain the written consent of the surety to the agreement.

9-1.07 PAYMENT AFTER ACCEPTANCE

After the work has been accepted in writing by the Director, as provided in Section 7-1.17, "Acceptance of Contract," payments will be made to the Contractor subject to the provisions in this Section 9-1.07.

9-1.07A PAYMENT PRIOR TO PROPOSED FINAL ESTIMATE

After acceptance of the work by the Director, the Engineer will make an estimate of the total amount of work done under the Contract and the City of Vallejo will make a final monthly payment pending issuance of the proposed final estimate. The City of Vallejo will pay the balance thereon found to be due after deduction of all previous payments, all amounts to be kept or retained under the provisions of the Contract and those further amounts that the Engineer determines to be necessary pending issuance of the proposed final estimate and payment thereon.

9-1.07B FINAL PAYMENT

After written acceptance of the Work as complete by the Director, or the Director’s designated representative, the Engineer will prepare and issue to the Contractor a proposed final estimate in writing of the total amount payable to the Contractor, including therein an itemization of the total amount, segregated as to Contract item quantities, extra work and any other basis for payment, and shall also show therein all deductions made or to be made for prior payments and amounts to be kept or retained under the provisions of the Contract. All prior estimates and payments shall be subject to correction in the proposed final estimate.

The Contractor shall submit written approval of the proposed final estimate or a written statement of all claims arising under or by virtue of the Contract so that the Engineer receives the written approval or statement of claims no later than close of business of the thirtieth day after receiving the proposed final estimate. If the thirtieth day falls on a Saturday, Sunday or legal holiday, then receipt of the written approval or statement of claims by the Engineer shall not be later than close of business of the next business day.

No claim will be considered that was not included in the written statement of claims, nor will any claim be allowed as to which a notice or protest is required unless the Contractor has strictly complied with the notice or protest requirements of the Contract Documents.

On the Contractor's approval, or if the Contractor files no claim within the specified period of 30 days, the Engineer will issue a final estimate in writing in accordance with the proposed final estimate submitted to the Contractor. The City of Vallejo will pay any remaining moneys unpaid and found to be due in the proposed final estimate 35 days after the recordation of the Notice of Completion in the records of the Solano County Recorder's Office as per Section 7-1.17, "Acceptance of Contract”. That final estimate H:\ENGR\CIP\9408 EV Charging-Parking Structure\2 - Fleming Hill and Corp Yard\05 - RFP Design\01 - Advertisement\Section B_PW 9408.docx
B-122
and payment thereon shall be conclusive and binding against Contractor on all questions relating to the amount of work done and the compensation payable therefor.

If the Contractor within the specified period of 30 days files claims, the Engineer will issue a semifinal estimate in accordance with the proposed final estimate submitted to the Contractor and within 30 days thereafter the City of Vallejo will pay the sum so found to be due. The semifinal estimate and payment thereon shall be conclusive and binding against the Contractor on all questions relating to the amount of work done and the compensation payable therefor, except insofar as affected by the claims filed within the time and in the manner required hereunder.
9-1.07C CLAIMS
The Claims procedures set forth in this section 9-1.07C are in addition to any claims procedures or rights available to Contractor pursuant to California Public Contract Code section 20104-20104.6 or California Public Contract Code section 9204 and Contractor’s exhaustion of its administrative remedies pursuant to this section 9-1.07C is a condition precedent to Contractor pursuing any claim pursuant to California Public Contract Code section 20104-20104.6 or California Public Contract Code section 9204 A. General. A “Claim” means a written demand or written assertion by Contractor to adjust, alter, modify, or otherwise change the Contract price or the Contract time, or both. All claims filed hereunder shall strictly comply with all requirements of the Contract Documents.

In order to qualify as a “Claim,” the written demand must state that it is a claim submitted under Section 9-1.07C of the Contract Documents. A letter, voucher, invoice, payment application, or other routine or authorized form of request for payment is not a Claim under the Contract Documents. If such a request is disputed as to liability or amount, then the disputed portion of the submission may be converted to a Claim under the Contract Documents by submitting a separate claim in compliance with claim submission requirements.

A Claim must be stated with specificity, including identification of the event or occurrence giving rise to the Claim, the date of the event, and the asserted affect on the Contract price and the Contract time, if any. The Claim shall include adequate supporting data. Adequate supporting data for a Claim for an adjustment of the Contract time shall include scheduling data demonstrating the impact of the event on the controlling operation and completion of the Project. Adequate supporting data for a Claim for an adjustment in the Contract price shall include a detailed cost breakdown of items included within the Claim and documentation supporting each item of cost.

Notwithstanding and pending the resolution of any Claim, the Contractor shall diligently prosecute the disputed work to final completion of the work. Contractor shall impose the Claim notice and documentation requirements in this Contract on

H:\ENGR\CIP\9408 EV Charging-Parking Structure\2 - Fleming Hill and Corp Yard\05 - RFP Design\01 - Advertisement\Section B_PW 9408.docx

B-123
Contractor’s subcontractors of all tiers, and require them to submit to the Contractor all Claims against Contractor and/or City within the times and containing the documentation required by these provisions. The Claim notice and documentation procedure described in these provisions applies to all claims and disputes arising under the Contract Documents, whether or not specifically referred to in any specific portion of the Contract.

If additional information or details are required by the Engineer to determine the basis and amount of any Claims, the Contractor shall furnish additional information or details so that the additional information or details are received by the Engineer no later than the fifteenth day after receipt of the written request from the Engineer.

If the fifteenth day falls on a Saturday, Sunday or legal holiday, then receipt of the information or details by the Engineer shall not be later than close of business of the next business day. Contractor understands and agrees that failure to submit the information and details to the Engineer within the time specified shall be result in Contractor waiving that Claim.

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

The City of Vallejo, or its authorized representatives, shall have access, upon reasonable notice, during normal business hours, to Contractor and subcontractors' books, documents and accounting records, including but not limited to, bid worksheets, bids, subcontractor bids and proposals, estimates, cost accounting data, accounting records, payroll records, time sheets, canceled checks, profit and loss statements, balance sheets, project correspondence including but not limited to all correspondence between Contractor and its sureties and subcontractors/vendors, project files, scheduling information, and other records of the Contractor and all subcontractors directly or indirectly pertinent to the work, original as well as change and claimed extra work, to verify and evaluate the accuracy of cost and pricing data submitted with any change order, prospective or completed, or any claim for which additional compensation has been requested or claim has been tendered. Such access shall include the right to examine and audit such records, and make excerpts, transcriptions, and photocopies at City of Vallejo's cost.

The parties agree that in the event Contractor or any subcontractor fails to comply with this section, it would be difficult for the City of Vallejo to determine its actual damages; therefore, Contractor agrees to pay City of Vallejo, as liquidated damages, the sum of Two hundred fifty dollars ($250.00), which Contractor agrees is reasonable under the circumstances, for each and every calendar day which H:\ENGR\CIP\9408 EV Charging-Parking Structure\2 - Fleming Hill and Corp Yard\05 - RFP Design\01 - Advertisement\Section B_PW 9408.docx
B-124
Contractor or a subcontractor fails or refuses to provide the City of Vallejo, access to the documents, records and materials specified in this section.

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

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

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

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

H:\ENGR\CIP\9408 EV Charging-Parking Structure\2 - Fleming Hill and Corp Yard\05 - RFP Design\01 - Advertisement\Section B_PW 9408.docx

B-125
price. Except as provided herein, the Contractor shall have no claim for damage or compensation for any delay, interruption, hindrance, or disruption.

"Unexcusable Delay" means any delay of the completion of the Project beyond the expiration of the Contract time resulting from causes other than those listed above.

An Unexcusable Delay shall not entitle the Contractor to an extension of the Contract time or an adjustment of the Contract price.

The Contractor may make a Claim for an extension of the Contract time, for an Excusable Delay or a Compensable Delay, subject to the following:

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

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

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

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

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

H:\ENGR\CIP\9408 EV Charging-Parking Structure\2 - Fleming Hill and Corp Yard\05 - RFP Design\01 - Advertisement\Section B_PW 9408.docx

B-126
suspension of the work, shall be governed by this provision.

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

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

D. Claim Procedures. Should any clarification, determination, action or inaction by the City, Work, or any event, in the opinion of the Contractor, exceed the requirements of or not comply with the Contract Documents, or otherwise result in the Contractor seeking additional compensation in time or money for any reason (collectively “Disputed Work”), then the Contractor and the City shall make good faith attempts to resolve informally any and all such issues and/or disputes. The Contractor must file a written Notice of Potential Claim with the City on the form provided in the Contract Documents before commencing the Disputed Work, or within seven (7) calendar days after Contractor’s first knowledge of the Disputed Work, whichever is earlier, stating clearly and in detail its objection and reasons for contending the Work or interpretation is outside the requirements of the Contract Documents. If a written Notice of Potential Claim is not filed within this time period, or if the Contractor proceeds with the Disputed Work without first having filed the notice required by these provisions, the Contractor shall waive any rights to further claim on the specific issue.

The City will review the Contractor’s timely Notice of Potential Claim and provide a decision. The City may require supplemental information from the Contractor to clarify that contained in the Notice of Potential Claim. If, after receiving the City’s decision, the Contractor disagrees with the decision, the Contractor shall so notify H:\ENGR\CIP\9408 EV Charging-Parking Structure\2 - Fleming Hill and Corp Yard\05 - RFP Design\01 - Advertisement\Section B_PW 9408.docx
B-127
the City, in writing, within seven (7) calendar days after receiving the decision, that a formal Claim will be filed. The Contractor shall submit the Claim in the form specified herein and all arguments, justification, costs or estimates, schedule analyses, and detailed documentation supporting the Contractor’s position within thirty (30) calendar days after receiving the City’s decision on the Notice of Potential Claim. The Contractor’s failure to furnish notification within seven (7) calendar days and all justifying documentation within thirty (30) calendar days will result in the Contractor waiving all rights to the subject Claim.

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

All Claims must be submitted to Engineer before the issuance of the final estimate.

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

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

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

Contractor shall be limited in its recovery on Claims to the calculations set forth in Section 9-1.03 of these provisions.

E. Claim Format. The Contractor shall submit the Claim justification in the following format:

The Contractor waives all claims of waiver, estoppel, release, bar, or any other type of excuse for non-compliance with the Claim submission requirements.

PW9408 SECTION D.0400 CPM CONSTRUCTION SCHEDULES
D-11
SECTION D.0400 - CPM CONSTRUCTION SCHEDULES
PART 1 GENERAL

1.01 SCOPE OF WORK
A. This work shall include the development of the initial Critical Path Method (CPM) construction schedule, and the monthly updating of the schedule (Progress Schedules) to reflect the progress of the work and any changes or modifications of the work during construction.

PART 2 MATERIALS

2.01 GENERAL
A. The initial CPM construction schedule and subsequent Progress Schedules shall be prepared using Microsoft Project 2010. The Contractor shall submit the initial CPM schedule, and each Progress Schedule, to the City in the form required in these specifications.

PART 3 EXECUTION

3.01 QUALIFICATIONS
A. The Contractor shall employ experienced scheduling personnel qualified in Critical Path Method scheduling techniques, and the use of Microsoft Project 2010. The Contractor may employ such personnel directly or may employ a services consultant for this purpose. After bid opening, the apparent successful low bidder shall provide the City with a written verification that the Contractor has the required personnel under its employ or that the Contractor will utilize a qualified CPM scheduling consultant. The written statement shall identify the individual who will perform CPM scheduling. The qualifications of the individual shall be verified by descriptions of construction projects on which the individual has successfully applied computerized CPM scheduling. The required level of experience shall include at least two projects of a similar nature, scope, and value. The written statement shall provide contact persons for referenced projects with current telephone and address information.

B. The City reserves the right to approve the Contractor’s scheduler, or consultant, and right to reject them at any time. The City also reserves the right to refuse replacement of the Contractor’s scheduler or consultant, if it believes such replacement will negatively affect performance of the Contract Documents.

PW9408 SECTION D.0400 CPM CONSTRUCTION SCHEDULES
D-12

3.02 GENERAL CPM SCHEDULE NOTES
A. The CPM construction schedule shall consist of an orderly and realistic plan for completion of the work. The CPM schedule shall include a series of activities and milestones, linked by relationships, set forth in a time-scaled manner. The CPM schedule shall be based on and incorporate milestone and completion dates specified in the Contract Documents. The overall time of completion and time of completion for each milestone shown on the CPM schedule shall adhere to times in the Contract Documents, unless an earlier (advanced) time of completion is requested by the Contractor and agreed to by the City. Any such agreement shall be formalized in a written Change Order. The City is not required to accept an earlier (advanced) schedule, i.e., one that shows completion dates earlier than that required in the Contract Documents. The Contractor shall not be entitled to additional compensation for completing the work prior to the completion date set forth in the Contract Documents, even if an earlier (advanced) time of completion is accepted by the City.

B. Neither the City nor the Contractor own float time. The Project owns the float time. As such, liability for delay of the Project Completion Date rests with the party whose unexcused delay, last in time, actually causes a delay to the Project Completion Date. For example, if Party A incurs an unexcused delay and uses some, but not all, of the float, and Party B later incurs an unexcused delay which uses all of the remaining float as well as additional time beyond the remaining float, then Party B shall be liable for the delay that represents a delay to the Completion Date. Party A would not be responsible for the delay to the Completion Date since it did not consume all of the float with its unexcused delay, and additional float remained, therefore, the Completion Date was unaffected by Party A.

C. The Progress Schedule shall be the basis for evaluating project progress, payment requests, and time extension requests. Responsibility for developing all Contract CPM schedules and monitoring actual progress as compared to the Progress Schedule rests with the Contractor.

D. Failure of the initial CPM schedule or Progress Schedules to include any element of the work or any inaccuracy in Progress Schedules shall not relieve the Contractor from responsibility for accomplishing the work in accordance with the Contract Documents. The City’s acceptance of schedules shall be for its use in monitoring and evaluating project progress, payment requests, and time extension requests, and shall not, in any manner, impose a duty of care upon the City, or act to relieve the Contractor of its responsibility for the means and methods of construction.

PW9408 SECTION D.0400 CPM CONSTRUCTION SCHEDULES
D-13

3.03 INITIAL CPM SCHEDULE
A. The Contractor shall submit the initial CPM schedule to the City for review at Pre-Design Conference and Pre-Construction conference.

The initial CPM schedule shall consist of a realistic, detailed proposal of how the Contractor will proceed with the orderly completion of the work, in conformance with the Contract Documents. By way of the Contractor assigning activity durations and proposing the sequence of the work, the Contractor agrees to utilize sufficient and necessary management of resources to perform the work in accordance with the schedule.

Submission of the Contractor’s schedule to the City shall not relieve the Contractor of total responsibility for scheduling, sequencing, and performing the work to comply with the Contract Documents, including dealing with adverse effects such as delays resulting from ill-timed work.

B. The initial CPM schedule shall be time-scaled. Each activity that requires actual labor to complete shall have a duration assigned, in working days.

Milestones, or zero-duration activities, can be assigned to major task completion points, such as Sewer Installation Complete, or single-event activities, such as Submittal of Pump Cut-Sheets.

C. The initial CPM schedule shall include all major activities pertaining to the completion of the work. Each activity will have a discrete activity name and number. No activity on the schedule shall have a duration of longer than fifteen (15) working days, with the exception of submittal, review and approval, fabrication, and procurement activities, unless otherwise approved by the City in writing.

D. All dependencies, or relationships, between activities shall be included in the initial CPM schedule. Only relationships of the Finish-to-Start and Start- to-Start type shall be used in the schedule.

E. The first activity on the schedule shall be a milestone activity corresponding to the award of Contract by the City Council. The last activity on the schedule shall be a milestone activity corresponding to the final acceptance of the project as complete by the City Council (Project Acceptance). All intervening activities shall have their start date linked directly to the Notice to Proceed, or to another activity that can be traced back to the Notice to Proceed.

F. The completion of each activity in the CPM schedule shall be linked to a subsequent activity or series of activities that can ultimately be traced to Project Acceptance. All activities, including predecessor activities proceeding through a Start-to-Start relationship to a successor activity, shall have a relationship subsequent to the completion of the predecessor activity that ultimately leads to Project Acceptance.

PW9408 SECTION D.0400 CPM CONSTRUCTION SCHEDULES
D-14
G. The CPM schedule shall clearly identify the activities that constitute the controlling operations, or Critical Path. Only one Critical Path from the Notice to Proceed activity to the Project Acceptance activity shall exist in the schedule. No more than twenty-five percent (25%) of the activities in the schedule shall be critical or near critical. Near critical is defined as having float of less than or equal to five (5) days.

H. City furnished materials, equipment, or activities playing a defined role in the project, if any, shall be identified as separate, individual activities. City review and/or processing activities shall be identified as separate, individual activities. The CPM schedule shall include the appropriate amount of time for submittals, City review of submittals, revisions to submittals, and re- review. The Contractor shall be responsible for any additional review cycles as a result of rejected submittals, without compensation for working days lost.

I. The CPM schedule shall include the procurement of major equipment or materials through receipt and inspection at the job site, including time for ordering, fabrication, delivery, and inspection. The CPM schedule shall show the dependencies (relationships) between procurement and construction.

J. The CPM schedule shall include a separate activity with a minimum of five (5) working days for City to develop a punch list after project completion.

Additionally, the CPM schedule shall include a separate activity with a minimum of five (5) working days for the Contractor to complete punch list activities. A minimum of ten (10) working days should be allotted between the project completion and project acceptance.

K. The CPM schedule shall show separate activities which identify periods of interface with utilities and other agencies.

L. Within ten (10) working days of the submittal of the initial CPM schedule, the City and the Contractor shall meet to review and discuss the initial CPM schedule, after the City has completed a review of the initial submittal. The City’s review and comment on the schedule will be limited to conformance with the Contract Documents and these specifications. The Contractor shall make the necessary corrections to the schedule to comply with the Contract Documents, and shall adjust the schedule to incorporate any missing information requested by the City. The Contractor shall resubmit the revised initial CPM schedule within five (5) working days of the meeting.

The resubmitted, revised schedule shall be considered as the “Original CPM Schedule”. The City may receive the Original CPM Schedule with no exceptions taken, or may require that the Contractor make additional revisions to the first updated CPM schedule (Progress Schedule).

PW9408 SECTION D.0400 CPM CONSTRUCTION SCHEDULES
D-15
M. The City reserves the right to require the Contractor to adjust, add to, or clarify any portion of the Original CPM Schedule which may later be discovered to be insufficient for monitoring the progress of the work or approval of partial payment requests. No additional compensation will be provided for such adjustments, additions, or clarifications.

N. Submittal of the Original CPM Schedule, and subsequent Progress Schedules, shall be understood to be the Contractor’s representation that the schedule meets the requirements of the Contract Documents and that work shall be executed in the sequence indicated on the schedule.

3.04 MONTHLY PROGRESS SCHEDULES

A. Progress Schedules shall conform to the provisions in Section 8-1.02, “Schedule,” of the Standard Specifications and these technical specifications.

B. The Contractor shall monitor progress of the work and shall update and adjust the schedule each month to reflect actual progress on schedule activities, any changes to activities, and the additional and/or subtraction of any activities due to change orders, additions, deletions, etc.

C. Each Progress Schedule submitted shall continue to show all activities, including those completed. Completed activities shall accurately reflect “as- built” information by showing when activities were actually started and actually completed.

D. Progress Schedules shall be submitted by the fifth working day of each month, with progress updated through the last calendar day of the previous month.

E. Within ten (10) working days of the submittal of the Progress Schedule, the City will complete a review and provide comments on the schedule. The City may reject the Progress Schedule, receive it with no exceptions taken, or may require that the Contractor make additional revisions to the next Progress Schedule.

F. The Progress Schedule will be utilized as part of the basis for the Contractor’s monthly application for payment. If the Progress Schedule is rejected, the Contractor’s application for payment will not be processed until the Progress Schedule has been revised, resubmitted, and either received with no exceptions taken or received with revisions to be made the following month.

3.05 SCHEDULE REVISIONS

A. Updating the schedule to reflect actual progress shall not be considered PW9408 SECTION D.0400 CPM CONSTRUCTION SCHEDULES
D-16
revisions to the schedule. However, the CPM schedule is recognized as a dynamic tool which changes as new information is acquired. Therefore, it is anticipated that revisions to activity durations and sequences may be expected on a monthly basis as the project proceeds.

B. To reflect revisions to the schedule, the Contractor shall provide the City with a written revision request prior to incorporation into a Progress Schedule. The revision request shall consist of a narrative with an itemized, full description and reason for each revision to the schedule.

C. Schedule revisions shall not be incorporated into any Progress Schedule until the City has reviewed the revision request. The City may request additional information and justification for schedule revisions and the Contractor shall, within three (3) working days, provide the City with a complete written narrative response to the City’s request.

D. If the Contractor’s revision request is not accepted by the City, and the Contractor disagrees with the City’s position, the Contractor has seven (7) calendar days from receipt of the City’s letter rejecting the revision request, to provide a narrative providing full justification and explanation for the revision. The Contractor’s failure to respond in writing within seven (7) calendar days of the City’s letter rejecting the revision request shall be contractually interpreted as acceptance of the City’s position, and the Contractor waives its rights to subsequently dispute or file of claims regarding the City’s position.

3.06 RECOVERY SCHEDULE
A. If the Progress Schedule shows Project Completion, or any other specified milestone date, occurring after the date required in the Contract Documents, the Contractor shall submit to the City a proposed plan to recover the lost time. The proposed plan shall be in writing and shall include a written narrative of any activity revisions, sequence changes, and other revisions proposed. If the revisions include sequence changes, the Contractor shall submit a schedule diagram comparing the proposed revised sequence of work to the Original CPM Schedule.

B. The proposed revisions shall not be incorporated into the Progress Schedule until reviewed by the City. If the Contractor’s proposed revisions are not accepted by the City, the Contractor shall follow the procedures in paragraph 3.04.C and 3.04.D above.

3.07 SCHEDULE IMPACTS DUE TO CHANGE ORDERS, AND OTHER DELAYS A. When the Contractor is directed to perform additional work under a Change Order, the Contractor shall prepare and submit to the City within ten (10) working days from the direction to proceed, a Schedule Impact Statement (SIS). The SIS shall include both a written narrative and a schedule

PW9408 SECTION D.0400 CPM CONSTRUCTION SCHEDULES
D-17
diagram depicting any impacts the Contractor feels that the Change Order work will have on other project activities and on the Critical Path. The SIS schedule diagram shall show how the Contractor proposes to incorporate the changed work into the CPM schedule, and whether a time extension will be required. Time extensions will only be granted if the Contractor can show conclusively that the changed work impacts the Critical Path.

B. The City will review the Schedule Impact Statement to confirm that the Contractor’s logic behind projected impacts to the schedule is appropriate.

If the City concurs with the Contractor’s projected impacts, the Contractor shall incorporate the revisions into the next Progress Schedule, and the Contract Time will be appropriately adjusted, if required. If the City does not concur with the Contractor’s projected revisions, and they are not accepted by the City, the Contractor shall follow the procedures in paragraph 3.04.C and 3.04.D above.

C. The Contractor shall be responsible for all costs associated with the preparation of the Schedule Impact Statement, and the process of incorporating revisions into the Progress Schedule.

D. The Contractor is responsible for requesting time extensions for time impacts resultant from Change Orders that, in the opinion of the Contractor, impact the Critical Path of the current Progress Schedule. Failure of the Contractor to request time extensions, provide an SIS, or provide required Recovery Schedules will result in the Contractor waiving its right to a time extension and any costs to mitigate delays.

E. The City shall not be obligated to consider any time extension request unless requirements of the Contract Documents are complied with. Failure of the Contractor to perform in accordance with the current Progress Schedule shall not be excused by the submittal of SISs. If the Contractor does not submit an SIS within the required ten (10) working days for any Change Order, it is mutually agreed that the Change Order has no impact to the schedule and the Contractor does not require any time extensions for that Change Order.

3.08 SCHEDULE SUBMITTALS

A. A minimum of five (5) working days prior to commencing the work, the Contractor shall submit a baseline schedule to the Engineer. The Contractor shall not commence work without a City-approved baseline schedule.

B. The Contractor shall submit a two-week look-ahead schedule on a weekly basis as well as an updated progress schedule on a monthly basis.

Progress payments may be withheld for failing to comply with these scheduling requirements as determined by the Engineer.

PW9408 SECTION D.0400 CPM CONSTRUCTION SCHEDULES

PART 3 EXECUTION

3.01 GENERAL
A. Where abandoned underground structures are encountered in the street areas, remove to sufficient depth to allow underground lines to cross, backfill and compact during rough grading. The ENGINEER may require further work to be done if visual inspection indicates during construction.

3.02 MINOR STRUCTURE EXCAVATION
A. General: Except when specifically provided to the contrary, excavation shall include the removal of all materials of whatever nature encountered, including all obstructions of any nature that would interfere with the proper execution and completion of the work. The removal of said materials shall

PW9408 SECTION D.2315 UTILITY EARTHWORK
D-101
conform to the lines and grades shown on the Drawings or ordered by the ENGINEER. Prior to commencing work by the contractor, the contractor shall furnish a cutsheet giving the layout and the elevation of the work with respect to said line and grade stakes. Unless otherwise provided, the entire construction site shall be stripped of all vegetation and debris, and such material shall be removed from the site prior to performing any excavation or placing any fill. The CONTRACTOR shall furnish, place, and maintain all supports and shoring that may be required for the sides of the excavations, and all pumping, ditching, or other measures required for the removal or exclusion of water, including storm water, groundwater, and wastewater reaching the site of the work from any source so as to prevent damage to the work or adjoining property. Excavations shall be sloped or otherwise supported in a safe manner in accordance with applicable State safety requirements and the requirements of OSHA Safety and Health Standards for Construction (29CFR1926). The limits of structure excavation shall be a minimum of 16 inches beyond the outside edge of the structure, and at a minimum no larger than necessary to facilitate backfill, compaction and testing operations. For structures poured against undisturbed soil the width of the structure wall shall be no more than 2 inches greater than specified or shown on the Drawings.

B. Excavation Beneath Minor Structures: Except where otherwise specified for a particular structure or as directed by the ENGINEER, excavation shall be carried to the grade of the bottom of the structure. When directed by the ENGINEER, areas beneath minor structures shall be over-excavated.

When such over-excavation is directed, both over-excavation and subsequent backfill to the required grade shall be performed. After over- excavation is performed and before backfill is placed, the exposed surface shall be scarified to a depth of 6 inches, brought to optimum moisture content, and rolled with heavy compaction equipment to obtain 90 percent of maximum density.

3.03 PIPELINE AND UTILITY TRENCH EXCAVATION

A. Trench Width: Unless otherwise shown or directed, excavation for pipelines and utilities shall be open-cut trenches. Trench widths shall be kept as narrow as is practical for the method of densification selected by the CONTRACTOR, but shall have a minimum width at the bottom of the trench equal to the outside diameter of the pipe plus 16 inches maximum. The minimum width at the top of the pipe shall be equal to the outside diameter of the pipe plus 12 inches for pipe diameters 8 inches and larger, and for pipe diameters less than 8 inches minimum trench width shall be not less than 18 inches in width. For deep trenches, the maximum width requirement may be waived for constructability reasons with the written approval of the ENGINEER. For telecommunications conduits (electrical, telephone, cable TV/communication conduits), street light and traffic signal

PW9408 SECTION D.2315 UTILITY EARTHWORK
D-102
conduits, the width of the trench shall be as shown on the City standard details.

B. Subgrade: The surface of the subgrade after compaction shall be hard, uniform, smooth, self-draining, and true to grade and cross section.

C. Trench Bottom: The pipe bedding shall be given a final trim establishing grade such that each pipe section when first laid will be continually in contact with the bedding along the extreme bottom of the pipe. Rounding out the trench bottom or bedding to form a cradle for the pipe will not be allowed. The CONTRACTOR shall excavate for bell holes and fittings.

D. Open Trench: The maximum amount of open trench permitted in any one location shall be the length necessary to accommodate the amount of pipe installed and backfilled in a single day. All trenches shall be fully backfilled at the end of each day or, in lieu thereof, shall be covered by heavy steel plates adequately braced and capable of supporting vehicular traffic in those locations where it is impractical to backfill at the end of each day. The above requirements for backfilling or use of steel plate may be waived in cases where the trench is located further than 100 feet from any travelled roadway or occupied structure. In such cases, however, barricades and warning lights meeting safety requirements shall be provided and maintained.

E. Trench Over-Excavation: Where indicated trenches shall be excavated to the depth shown, and then backfilled to the grade of the bottom of the Pipe Zone.

F. Over-Excavation: When ordered by the ENGINEER, whether or not indicated on the Drawings, trenches shall be over-excavated beyond the depth shown. Such over-excavation shall be to the depth ordered. The trench shall then be backfilled to the grade of the bottom of the Pipe Zone.

G. Where pipelines are to be installed in embankment or structure fills, the fill shall be constructed to a level a minimum of 2 feet above the top of the pipe, as directed by the ENGINEER, or as recommended by the pipe manufacturer, whichever is greater, before the trench is excavated.

3.04 OVER-EXCAVATION NOT ORDERED, SPECIFIED, OR SHOWN

A. Any over-excavation carried below the grade ordered, specified, or shown, shall be backfilled to the required grade and densified with the specified material and compaction. Such work shall be performed by the CONTRACTOR at its own expense.

3.05 EXCAVATION IN VICINITY OF TREES
PW9408 SECTION D.2315 UTILITY EARTHWORK
D-103
A. Except where trees are shown to be removed, trees shall be protected from injury during construction operations. No tree roots over 2 inches in diameter shall be cut without express permission of the ENGINEER. Trees shall be supported during excavation by any means previously reviewed by the ENGINEER.

B. If existing roots over one inch in diameter are cut during the course of the work, the cut faces shall be thoroughly coated with emulsified asphalt made especially for use on cut or damaged plant tissues. Exposed roots shall be covered with wet burlap to prevent them from drying out.

3.06 ROCK EXCAVATION
A. Rock excavation shall include removal and disposal of the following: (1) all boulders measuring 1/3 of a cubic yard or more in volume; (2) all rock material in ledges, bedding deposits, and unstratified masses; (3) concrete or masonry structures which have been abandoned; and (4) conglomerate deposits which are so firmly cemented that they possess the characteristics of solid rock.

B. Explosives and Blasting: Use of Explosives and Blasting will not be permitted.

3.07 DISPOSAL OF EXCESS EXCAVATED MATERIAL
A. The CONTRACTOR shall remove and dispose of all excess excavated material to a suitable site. The proper and legal disposal shall be the responsibility of the CONTRACTOR.

3.08 BACKFILL - GENERAL

B. Backfill shall not be placed until after all water is removed from the excavation.

3.09 PIPE AND UTILITY TRENCH ZONES AND BACKFILL
A. Pipe Zone and Backfill (Initial Backfill) :

1. The Pipe Zone is defined as that portion of the vertical trench cross- section lying between a plane 6 inches below the bottom surface of the

PW9408 SECTION D.2315 UTILITY EARTHWORK
D-104
pipe, i.e., the trench subgrade, and a plane at a point 12 inches above the top surface of the pipe.

2. The Pipe Zone shall be backfilled with the specified backfill material. The CONTRACTOR shall exercise care to prevent damage to the pipeline coating, cathodic bonds, or the pipe itself during the installation and backfill operations.

B. Bedding: The bedding is defined as that portion of the Pipe Zone lying between a plane 6 inches below the bottom surface of the pipe, the trench subgrade, and a level line from the bottom of the pipe.

1. Bedding shall be provided for all pipelines.

2. After compacting the bedding the CONTRACTOR shall perform a final trim for establishing grade, such that each pipe section when first laid will be continually in contact with the bedding along the extreme bottom of the pipe.

C. Trench Zone and Backfill (Subsequent Backfill) : After the Pipe Zone backfill has been placed as specified above, and after all excess water has completely drained from the trench, backfilling of the Trench Zone may proceed.

1. The Trench Zone is defined as that portion of the vertical trench cross- section lying between a plane 12 inches above the top surface of the pipe and a plane at a point 30 inches below the roadway subgrade in paved areas, or 30 inches below the finished surface grade in landscaped or unimproved areas.

D. Final Zone and Backfill: The Final Zone is defined as the last 30 inches between the top of the Trench Zone and the roadway subgrade in paved areas, and the last 30 inches of the vertical trench cross-section lying between the top of the Trench Zone and the finish final grade in landscaped or unimproved areas.

E. Utility Crossing: For any new pipeline installation that crosses under an existing electric, gas, telephone, or cable tv utility pipe(s) or conduit(s) the CONTRACTOR shall replace the existing backfill material around the existing utility pipe(s) or conduit(s) with PG&E SAND.

1. PG&E SAND shall be placed from a plane 6 inches below the bottom of the lowest utility pipe or conduit to a plane 12 inches above the top of the highest utility pipe or conduit, and for the full width of the new trench.

PG&E SAND backfill shall be compacted to 95 percent maximum density in conformance with COMPACTION AND BACKFILL MATERIALS as PW9408 SECTION D.2315 UTILITY EARTHWORK
D-105
specified below.

3.10 PLACING AND SPREADING OF BACKFILL MATERIALS
A. Backfill materials shall be placed and spread evenly in horizontal layers.

The backfill layers shall be evenly spread so that when each layer compacted shall not exceed 6 inches in thickness.

B. During spreading each layer shall be thoroughly mixed as necessary to promote uniformity of material in each layer and uniformity of moisture throughout backfill materials. Pipe Zone backfill materials shall be manually spread around the pipe so that when the Pipe Zone backfill compacted will provide uniform bearing and side support.

C. Where the backfill material moisture content is below the optimum moisture content water shall be added before or during spreading until the proper moisture content is achieved.

D. Where the backfill material moisture content is too high to permit the specified degree of compaction, the material shall be dried or replaced until the moisture content is satisfactory.

E. Backfill shall be mechanically compacted by means of tamping rollers, sheepsfoot rollers, pneumatic tire roller, vibrating rollers, or other mechanical tampers. All such equipment shall be of a size and type subject to review by the ENGINEER. Impact-type pavement breakers (stompers) will not be permitted. Permission to use specific compaction equipment shall not be construed as guaranteeing or implying that the use of such equipment will not result in damage to adjacent ground, existing improvements, or new improvements. The CONTRACTOR shall make its own determination in this regard.

F. Material for mechanically compacted backfill may be placed in loose lifts which, prior to compaction, shall not exceed the thickness specified below for various types of equipment:

1. Vibratory equipment, including vibratory plates, vibratory smooth-wheel rollers, and vibratory pneumatic-tired rollers - maximum lift thickness of 2 feet.

2. Rolling equipment, including sheepsfoot (both vibratory and non- vibratory), grid, smooth-wheel (non-vibratory), pneumatic-tired (non- vibratory), and segmented wheels - maximum lift thickness of 1 foot.

3. Hand-directed mechanical tampers-maximum lift thickness of 4 inches.

PW9408 SECTION D.2315 UTILITY EARTHWORK
D-106
G. Mechanically compacted landfill shall be placed in horizontal layers of thickness not exceeding those specified above, compatible to the material being placed and the type of equipment being used. Each layer shall be evenly spread, moistened or dried, if necessary, and then tamped or rolled until the specified relative compaction has been attained.

3.11 COMPACTION OF BACKFILL MATERIALS
A. Each layer of backfill material as defined herein, shall be mechanically compacted to the specified percentage of maximum density. Equipment that is consistently capable of achieving the required degree of compaction shall be used and each layer shall be compacted over its entire area while the material is at the required moisture content range.

B. Flooding, ponding, or jetting shall not be used.

C. Equipment weighing more than 10,000 pounds shall not be used closer to structure walls than a horizontal distance equal to the depth of the fill against the structure wall at that time. Hand operated power compaction equipment shall be used where use of heavier equipment is impractical or restricted due to weight limitations.

D. Compaction Requirements: The following compaction test requirements shall be in accordance with ASTM D 1557 for cohesive type materials and in accordance with ASTM D 4253 and D 4254 for “non-plastic” cohesionless free draining granular type materials. Where other agency or utility company requirements govern, the highest compaction standards shall apply.

City of Vallejo Water Plant
Overview
• 202 Fleming Hill Road, Valencia CA
• Mark Helmbrecht, Transportation Superintendent 707 645-2601 [email protected] • Requested 6 Networked L2 ports.

Power
• Water Plant is a Critical City Service.
• Site is maxed out on electrical capacity and hesitant to add load to existing infrastructure. • Main Switch location is ¼ mile down the hill, not possible to add power or panels from that location. • One 30A breaker installed on a 100A panel for single Clipper Creek charging port, unsure is it is actually dedicated load. • Panel is wired for one additional port. Doubt dedicated load is available to support additional charging port(s). • Existing conduit full from panel room to Jbox . However, if electrical capacity is available, no issues getting wire from Jbox to port. • Possible to do a load study, however results may only verify visual inspection and facility manager expectations, no capacity. • Best solution is new PG&E 400A Service drop to support 10-20 charging ports in spaces closer to the main gate.

Port Location
• Employee parking very tight. Do not want to give up parking for charging spaces. • Potential to remove existing Clipper Creek port and install 1 dual station with PowerShare farther along existing row. • Potential to relocate visitor parking and convert to charging spaces as Jbox is 15ft from the location.
