REQUEST FOR BIDS

RECEIPT OF BID: Please provide your written bid (on the attached forms) to the Santa Ynez River Water Conservation District, Improvement District No. 1 (District), before 9:00 AM on the 6

th of November, 2015.

BID SECURITY: Each bid shall be accompanied by a certified or cashier’s check or bid bond in the amount of ten percent (10%) of the total bid price, payable to the District as a guarantee that the bidder, if its bid is accepted, will promptly execute the Agreement and provide the required submittals for approval, all within ten (10) calendar days of the date of written Notice of Award. A bid shall not be considered unless one of the forms of bidder security is enclosed with it.

DESCRIPTION OF WORK: The subject Reservoir No. 2 is a potable water storage facility which is approximately 280' long and 155' wide. The maximum depth of the reservoir is approximately 30 ft and has a storage capacity of 6.5MG. The maximum operating depth of the reservoir is approximately 25 ft. The reservoir has a structural roof with access to the reservoir via a 5 Ft x 6 Ft hatch. The floor and slopes of the reservoir are constructed of a layer of shotcrete over compacted soil, with a total surface area of approximately 56,300 Sq. Ft. The floor and sloped walls are covered with an existing flexible membrane liner system comprised of approximately 62,675 Sq. Ft. of chlorosulfonated polyethelene (CSPE), commonly known as “Hypalon”. The existing Hypalon liner was installed over the original liner material, an approximately ½” thick prefabricated asphalt panel product called Panelcraft. Previous inspections have determined the presence of irregularities in the shotcrete floor beneath the existing liner(s) and that portions of the floor and sidewalls are extremely uneven in localized areas.

This project will consist of installing a new flexible membrane liner system to be comprised of a new 60 mil reinforced Hypalon (CSPE R) membrane overlying a new non woven geotextile. In advance of the new liner system installation, the Contractor will remove and disposal of accumulated sediment and clean the existing liner surface to permit inspection. The Engineer and Contractor shall inspect the existing liner and determine the extent to which the existing liner(s) and underlayment(s) will require removal. The limits of removal of the existing liner materials shall be sufficient to permit exposure of areas in the reservoir floor and sides which exhibit surface irregularities in the existing shotcrete and/or conditions which are unacceptable for placement of the new liner system. The liner(s) and underlayment(s) that are removed shall be disposed of by the Contractor. Prior to the installation of the new liner system, the Contractor shall repair all deteriorated or damaged areas of the shotcrete reservoir floor and sloped walls; concrete reservoir column bases; and the existing concrete inlet and outlet structures, in a manner which creates suitable surfaces for placement and attachment of the new liner system. The Engineer and Contractor shall inspect all existing liner system anchor bolts and batten strips and replace those bolts / strips which are deemed unsuitable by the Engineer. Additional work shall include the repair and recoating of the existing steel access ladder and the removal of the non operational existing water level measurement device (including appurtenances). Prior to demobilization, the Contractor shall clean and disinfect the reservoir in accordance with AWWA Standard C652 and prepare the reservoir for refilling by the District. The Contractor shall contain all wash down fluids from the liner cleaning operations and dispose of those fluids offsite in a legal manner. The Contractor will supply all materials, tools, and labor required to complete the work.

SITE OF WORK: Construction will occur within the District’s Treated Water Storage Reservoir #2 site. The property is located approximately ½ mile north of the town of Ballard at 2205 Alamo Pintado Road.

COMPLETION OF WORK: All work must be completed in an expeditious manner. No liquidated damages will be imposed under this contract, but the District reserves the right to terminate the Contract if the work is not being pursued diligently and expeditiously in accordance with the Contract Documents.

PAYMENT: Payment shall be made by the Owner, to ninety five (95) percent of the work completed in monthly progress payments and a final payment. The five (5) percent retention will be paid 35 days following final acceptance of the work by the District’s Board of Trustees.

FORM OF BID: The bid shall be made on the Bid Forms bound herein (unless modified by an addendum).



MANDATORY PRE�BID MEETING: All bidders are required to attend the pre bid meeting at the District office (3622 Sagunto St., Santa Ynez) scheduled for October 23, 2015, at 11:00 AM. The pre bid meeting will include inspection of the work site.

INSPECTION OF SITE OF WORK: Inspection of the site of the work is required in order for the Contractor to satisfy himself, by personal examination, of the location of the proposed work and as to the actual conditions of and at the site of work. If during the course of his examination, a Contractor finds facts or conditions which appear to him to conflict with the letter or spirit of the Contract Documents (including Drawings and Specifications), or with any other data furnished him, he may contact the District for additional information and explanation before submitting his bid.

The submission of a bid by the Bidder shall constitute the acknowledgment that, if awarded the contract, he has relied and is relying on his own examination of (a) the site of the work, (b) the access to the site, and (c) all other data, matters, and things requisite to the fulfillment of the work and on his own knowledge of existing services and utilities on and in the vicinity of the site of the work to be constructed under the contract, and not on any representation or warranty of the District. No claim for additional compensation will be allowed which is based upon a lack of knowledge of the above items.

AWARD OF CONTRACT: Bids will be evaluated and contract awarded when the District has received bids from solicited Contractors showing interest and knowledge of the described work, and will follow the scheduled Board of Trustees meeting on the 17

th of November, 2015. Upon written notice of award, the

Contractor shall promptly execute the Agreement, provide the required insurance submittals, secure payment of workmen’s compensation insurance, and furnish satisfactory Performance Bond and Payment Bond, both in the amount of 100 percent of the bid price.

The Contractor shall retain any and all rights provided either by contract or by law which pertain to the resolution of disputes and protests between the contracting parties.

III.6. Lines and Grades

Except as noted in the Technical Specifications herein, the Contractor shall be responsible for setting and maintaining lines and grades.

The superintendent shall have full authority to act on behalf of the Contractor, and all directions received by the superintendent from District Representative shall be considered received by the Contractor.

III.8. Protest

If the Contractor considers any work demanded of him to be outside the scope of the contract, or any order, instruction or decision by the District Representative to be unfair, he shall, immediately ask for a written confirmation of the same, whereupon he shall file a protest with the Owner within (10) ten days clearly stating in detail his objections and reasons therefore and proceed without delay to perform the work. Except for such protest or objections made as required, the Contractor hereby waives all grounds for protest or objections.

III.9. Inspection

a. The District Representative shall, at all times, have access to the Work during its construction and shall be furnished with every reasonable facility for ascertaining that the stock and materials used and employed, and the workmanship are in accordance with the requirements and intentions of the Specifications. All work done and all materials furnished shall be subject to his inspection and approval. If any work should be performed or covered up without approval or consent of the Representative, it must, if required by the District Representative, be uncovered for examination at the Contractors expense.

b. Reexamination of work previously inspected by Owner or District Representative may be ordered by the District Representative and if so ordered, the work must be uncovered by the Contractor. If such work be found in accordance with the Contract, the Owner shall pay the cost of reexamination. If

c. The inspection of the Work shall not relieve the Contractor of any of his obligations to fulfill his contract as prescribed, and defective work shall be made good and unsuitable materials shall be rejected, not withstanding that such defective work and materials have been previously overlooked and accepted on estimates for payment.

III.11. Subcontracts

a. Subcontractors who will perform one half of one percent, or more, of the work, shall be listed in the Contractor’s bid.

b. At the District Representative's discretion, subcontracts may be permitted to such extent as shall be shown to be necessary or advantageous to the Contractor in the execution of the work and without injury to the Owner's interests.

Proper licensing shall be available to the District Representative from any subcontractor.

d. The Contractor shall be responsible, as with his own employees, for acts or omissions by the subcontractor.

e. The attention of the Contractor is directed to the provisions of Public Contract Code sections 4100 through 4114, inclusive, regarding subcontracting and said provisions are by this reference incorporated herein and made a part hereof.

f. Each subcontract shall contain a suitable provision for the suspension or termination thereof should the work be suspended or terminated or should the Subcontractor neglect or fail to conform to every provision of the Contract Documents insofar as such provisions are relevant. No Subcontractor or supplier will be recognized as such, and all persons engaged in work will be considered as employees of the Contractor and the Contractor will be held responsible for their work, which shall be subject to the provisions of the Contract Documents. The Contractor shall be fully responsible to the District for the acts or omissions of his Subcontractors and the persons either directly or indirectly employed by him. Nothing contained in the Contract Documents shall create any contractual relationship between any Subcontractor and the District. If a legal action, including arbitration and litigation, against the District is initiated by a Subcontractor or Supplier, the Contractor shall reimburse the District for the amount of legal, District Representative time, and all other expenses incurred by the District in defending itself in said action.

g. The District reserves the right to approve all subcontractors. Such approval shall be a consideration to the awarding of the Contract and unless notification to the contrary is given to the Contractor prior to the signing of the Contract, the list of subcontractors which is submitted with his bid will be deemed to be acceptable.

III.12. Suspension of Work



The Owner, acting through the District Representative, may, at any time and without cause, suspend the work or any portion thereof for a period of not more than 90 days by notice in writing to the Contractor. The Contractor shall resume the work on receipt from the District Representative of a notice of resumption of work. The Contractor will be allowed an increase in the Contract Price or an extension of the Contract Time, or both, directly attributable to any suspension if the Contractor makes an approved claim as provided in the General Conditions.

III.13. Termination of Right To Proceed

a. Should the Contractor fail to meet any or all of the requirements of the contract, be placed or entered into bankruptcy, have a receiver appointed for his properties or make an assignment for the benefit of creditors, the Owner may declare the Contractor in default of Contract by notifying the Contractor in writing. The Contractor shall preserve all aspects of the project site and take immediate steps to remedy such default.

b. If after 5 calendar days said default is not remedied, the Owner may, in writing terminate the Contractor's right to proceed and the Contractor shall at his own expense:

iii. Remove all material, equipment and plant not listed in said inventory.

c. The Owner has the right to complete the work using any or all the materials, plant, tools, equipment, supplies and property furnished by the Contractor. The total cost of completing the project shall be charged to the Contractor and the Owner may use sole judgment in gathering figures for the completion of the work.

III.14. Termination of Agreement by Owner (For Convenience)

a. The Owner may terminate the Agreement at any time if it is found that reasons beyond the control of either the Owner or Contractor make it impossible or against the Owner's interests to complete the work. In such a case, the Contractor shall have no claims against the Owner except for the value of work performed up to the date the Agreement is terminated and for the cost of materials and equipment on hand, in transit, or on definite commitment, as of the date the Agreement is terminated, which would be needed in the work and which meet the requirement of the Contract Documents.

b. The value of the work performed and the cost of materials and equipment delivered to the site, as mentioned above, will be determined by the District Representative in accordance with the procedure prescribed for the making of the final application for payment.

c. The Contractor shall assign to the Owner, as directed by the District Representative, all right, title, and interest to the Contractor under the subcontracts terminated, in which case the Owner shall have the right to settle or to pay any termination settlement arising out of those terminations.

d. As directed by the District Representative, the Contractor shall transfer title and deliver to the Owner (i) the fabricated or unfabricated parts, work in progress, completed work, supplies, and other material produced or acquired for the work terminated, and (ii) the completed or partially completed plans, drawings, information, and other property that, if the contract has been completed, would be required to be furnished to the Owner.

III.15. Failure To Comply

If the Contractor should refuse or neglect to comply with the provisions of the Contract or of the orders of the District Representative, the Owner may have such provisions or orders carried out by others at the Contractor's expense.

IV. MATERIALS AND WORKMANSHIP



IV.1. Safeguarding of Equipment, Materials, and Work

The Contractor shall properly safeguard all equipment, materials and work against loss, damage, malicious mischief, or tampering by unauthorized persons until final acceptance by the Owner.

IV.2. Defective Work or Material

a. The Contractor shall promptly remove from the Owner’s premises all work and materials rejected by the District Representative as failing to conform to the Contract, whether incorporated or not, and the Contractor shall promptly replace and re execute the work in accordance with the Contract and without expense to the Owner and shall bear the expense of correcting all work of other contractors destroyed or damaged by such removal or replacement.

b. If the Contractor does not remove such rejected work or materials within a reasonable time after notice, the Owner may remove them and store the materials at the expense of the Contractor. If the Contractor does not pay the expenses of such removal within ten (10) days' time after such removal, the Owner may, upon thirty (30) days written notice, sell such materials at auction or at private sale and shall account for the net proceeds thereof after deducting all the cost and expenses that should have been borne by the Contractor.

c. Any work done beyond the lines and grades shown on the plans and established by the District Representative, or any extra work done without written authority, will be considered as unauthorized work and will not be paid for.

IV.3. Contractor’s Utilities

a. The Contractor shall provide his own water, telephone and all electric power required in performance of the work under the Contractor.

b. Chemical toilets for the use of all persons employed on the Work shall be provided by the Contractor in sufficient number, and in such manner and at such places as shall be approved by the District Representative. The fixtures and the surrounding premises shall be kept in a clean sanitary condition.

IV.4. Cleanup and Dust Control

a. During construction, the Contractor shall keep the site free and clean from all rubbish, debris, and shall clean up the site promptly when notified to do so by the District Representative. Care shall be taken to prevent spillage on streets and access roads over which hauling is done, and any such spillage or debris deposited on streets and access roads due to the Contractor's operations, shall be immediately cleaned up.

b. The Contractor shall, at his own expense, maintain the streets and access roads free from dust and mud, excess earth or debris. If any streets or access roads are damaged by the Contractor as a result of his operations, Contractor shall be responsible for repairing such damaged street or access road to their original condition.

c. Upon completion of any resurfacing or excavation, the street or access road shall be immediately swept clean of all dust and debris. Sweeping shall be done at such times and in such a manner as to minimize creation of dust.

d. The Contractor shall coordinate his operations in such a manner as to prevent the amount of cleanup and completion of back work from becoming excessive. Should said condition arise, the District Representative may halt all operations and order all or portions of back work to be completed before continuing.

e. The Contractor shall leave all work sites in a neat, presentable appearance at the end of each workday.

IV.5. Public Convenience and Safety



The Contractor shall so conduct his operations as to cause the least possible obstruction and inconvenience to public traffic. The Contractor shall furnish, erect, and maintain such fences, barriers, lights, and signs as are necessary to give adequate warning to the public at all times that the improvement is under construction and of any dangerous conditions to be encountered as a result thereof, and he shall also erect and maintain such warnings and directional signs as may be furnished by the Owner. Full compensation for conforming to the provisions of this subsection shall be considered as included in the prices paid for the various contract items of work and no additional compensation will be allowed therefore. Contractor shall be in compliance with all County, State, and Federal ordinances, or laws at all times.

V. PROGRESS AND PAYMENT

V.1. Changes in the Work

The District may, at any time, by written order make changes in the work as deemed necessary by the District Representative. If such changes cause an increase or decrease in the Contractor’s cost of, or time required for, performance of the Contract an equitable adjustment will be made and the Contract modified in writing accordingly.

Such modification will be in the form of a Contract Change Order which will set forth the work to be done or the method by which the change and cost adjustment, if any, will be determined, and the time of completion of the work. A Contract Change Order Form is attached to these Contract Documents.

The compensation to be paid for extra work or change shall be determined in one or more of the following ways:

� By agreed unit prices; � By estimate and acceptance of an agreed upon lump sum; or � By cost plus.

Until one of the above methods is agreed on, or if the work is to be paid for on a cost plus basis, the Contractor shall keep full and complete records of the cost of such work in the form and manner prescribed by the District Representative and shall permit the District Representative to have access to such records as may be necessary to assist in the determination of the compensation payable for such work. Contractor must obtain the District Representative’s permission, on a daily basis, as to the size of the crew, hours worked, and material to be used.

Upon receipt of a Contract Change Order, the Contractor shall proceed with the ordered work. If ordered in writing by the District Representative, the Contractor shall proceed with the work so ordered prior to actual receipt of a Contract Change Order. A Contract Change Order executed by the Contractor and approved by the District Representative is an executed Contract Change Order as that term is used throughout this Section. A Contract Change Order may be issued to the Contractor at any time. Should the Contractor disagree with any terms or conditions set forth in a Contract Change Order which he has not executed, he shall submit a written protest to the District Representative within ten (10) days after the receipt of such Contract Change Order. The protest shall state the points of disagreement, and, if possible, the quantities and cost involved. If a written protest is not submitted, payment will be made as set forth in the Contract Change Order and such payment will constitute full compensation for all work included therein or required thereby. Such unprotested Contract Change Orders will be considered as executed Contract Change Orders.

Where the protest concerning a Contract Change Order relates to compensation, the compensation payable for all work specified or required by said Contract Change Order to which such protest relates will be determined in the same manner as provided in Section V.3 for claims for extra work. The Contractor shall keep full and complete records of the cost of such work and shall permit the District Representative to have such access thereto as may be necessary to assist in the determination of the compensation payable for such work.

Where the protest concerning a Contract Change Order relates to the adjustment of time and the completion of the work, the time to be allowed therefore will be determined as provided in this Section.



The consent of the Contractor’s sureties shall not be required as to any change or extra work, and the liability of the Contractor’s Bonds shall be increased or decreased accordingly without notice to the sureties.

In accordance with Government Code Section 4215, the Contractor shall be compensated for the costs of locating, repairing damage not due to the failure of the Contractor to exercise reasonable care, and removing or relocating existing main or trunkline utility facilities not indicated in the Contract Plans and Specifications with reasonable accuracy, and for the equipment on the project necessarily idled during such work; provided that the Contractor shall first notify the District Representative before commencing work on locating, repairing damage to, removing, or relocating such utilities.

V.2. Claims for Extra Cost

a. It is hereby mutually agreed that the Contractor shall not be entitled to the payment of any additional compensation for any cause, including any act, or failure to act, by the District Representative, or the happening of any event, thing, or occurrence, unless he shall have given the District Representative due written notice of potential claims hereinafter specified, provided, however, that compliance with this section shall not be a prerequisite as to matters within the scope of the protest provisions in Section III.8.

b. The written notice of potential claims shall set forth the reasons for which the Contractor believes additional compensation will or may be due, the nature of the costs involved, and insofar as possible, the amount of the potential claim. The notice as above required shall be given to the District Representative prior to the time that the Contractor commences performance of the work giving rise to the potential claim for additional compensation, if based on an act or failure to act by the District Representative, or in all other cases within ten (10) days after the happening of the event, thing or occurrence giving rise to the potential claim.

c. The Contractor may submit a claim to the District Representative concerning any matter for which a protest under Section III.8. or a notice of potential claim is filed within sixty (60) days following the submission of said protest or notice, unless, due to the nature of the claim or the uncompleted state of the work, it is impracticable to determine the amount or the extent of the claim within such period, in which case a claim may be submitted at the earliest time thereafter that such determination can be made, but in no event later than the final release by the Contractor. The claims shall set forth clearly and in detail, for each item of additional compensation claimed, the reasons for the claim, reference to applicable provisions of the Specifications, the nature and the amount of the cost involved, the computations used in determining such costs, and all pertinent factual data. The Contractor shall maintain complete and accurate records of the cost or any portion of the work for which additional compensation is claimed, and shall provide the District Representative with copies thereof, as required.

d. The District Representative will, within a reasonable time after submission of the Contractor’s claim, make decisions in writing on all claims of the Contractor. All such decisions of the District Representative shall be final unless the Contractor shall within ten (10) days after receipt of the District Representative’s decision, file with the District Representative a written protest, stating clearly and in detail the basis thereof. Such protest will be forwarded promptly by the District Representative to the District, which will issue a decision upon each such protest, and the District’s decision will be final. Pending such decision, the Contractor shall proceed with his work in accordance with the determination or instructions of the District Representative. It is hereby agreed that the Contractor’s failure to protest the District Representative’s determination or instructions, within ten (10) days from and after the District Representative’s determinations or instructions, shall constitute a waiver by the Contractor of all his rights to further protest, judicial or otherwise.

e. It is the intention of this Section that the differences between the parties, arising under and by virtue of the Contract, be brought to the attention of the District Representative at the earliest possible time in order that such matters may be settled, if possible or other appropriate action promptly taken. The Contractor hereby agrees that he shall have no right to additional compensation for any claim that may be based on any act, failure to act, event, thing, or occurrence for which no written notice of potential claim as herein required was timely filed.



f. In the event of an emergency endangering life or property, the Contractor shall act under the direction of the Owner, and after execution of the emergency work shall present an accounting of labor, materials, and equipment in connection therewith. The procedure for any payment that may be due for emergency work will be as specified in Section V.2. herein.

g. Right to Audit: If the Contractor submits a claim to the Owner for additional compensation, the Owner shall have the right, as a condition to considering the claim, and as a basis for evaluation of the claim, and until the claim has been settled, to audit the Contractor’s books to the extent they are relevant. This right shall include the right to examine books, records, documents, and other evidence and accounting procedures and practices, sufficient to discover and verify all direct and indirect costs of whatever nature claimed to have been incurred or anticipated to be incurred and for which the claim has been submitted. The right to audit shall include the right to inspect the Contractor’s plans, or such parts thereof, as may be or have been engaged in the performance of the work. The Contractor further agrees that the right to audit encompasses all subcontracts and is binding upon Subcontractors. The rights to examine and inspect herein provided for shall be exercisable through such representatives as the Owner deems desirable during the Contractor’s normal business hours at the office of the Contractor. The Contractor shall make available to the Owner for auditing, all relevant accounting records and documents, and other financial data, and upon request, shall submit true copies of requested records to the Owner.

V.3. Overtime Work

Except as otherwise provided in this Section, the Contractor shall receive no additional compensation for overtime work even though such overtime work may be required under emergency conditions and may be ordered by the District Representative in writing. Additional compensation will be paid to the Contractor for over time work only in the event extra work is ordered by the District Representative in writing and the Change Order specifically authorizes the use of overtime work, and then only to such extent as overtime wages are regularly being paid by the Contractor for overtime work of a similar nature in the same locality.

V.4. Delays and Extension of Contract Time

a. Any extension of Contract Time must be requested in writing by the Contractor. The Contractor may be entitled to an extension of contract time: (1) if the work has been suspended by the Owner, in whole or in part of (2) where weather or other circumstances occur which delay progress and which are clearly beyond the control of the Contractor; provided that; in either case, the Contractor is not at fault and has not breached the terms of the Contract. The Contractor has sole responsibility for his subcontractor’s timely completion of work. The extension of time allowed shall be as determined by the District Representative.

b. The Owner shall have the right to extend the time for completing the work if it determines such extension to be in the best interest of the Owner; however, if the Owner extends the time limit for the completion of the work, by way of a change order, at the request of the Contractor, for other than acts of God and situations beyond the control of both parties, it is understood and agreed that such time extension will increase the Owner financial obligations incurred for District Representative, inspection, supervision, incidental and overhead expenses that are directly chargeable to the contract and that accrue during the period of extension. Therefore, the Contractor does hereby acknowledge that reasonable charges for the hereinabove Owner expense shall be reimbursed to the Owner by the Contractor before the final payment of the 10 percent retention.

c. The Contractor shall within ten (10) calendar days from the beginning of any such delay (unless the Owner shall grant a further period of time to the date of final settlement of the Contract) notify the Owner in writing of the cause of delay, whereupon the Owner shall ascertain the facts and extent of the delay and extend the time for completing the work if in its judgment the findings of fact justify such an extension, and its findings of fact thereon shall be final and conclusive on the parties hereto. In addition, the District shall have the right to charge to the Contractor and to deduct from the final or progress payments for the work the actual cost to the District of legal, inspection, superintendence, and other expenses, which are directly chargeable to the Contract and which accrue during the period of such



delay, except that the cost of final inspection and preparation of the final estimate shall not be included in the charges.

V.5. Final Inspections

Final inspection and acceptance of the work shall be made for the Owner by the District Representative. Such inspection shall be made as soon as practical after the Contractor has notified the Owner that the work is ready for such inspection.

V.6. Progress Payments and Final Payment

a. Progress payments will be made as described in the Request for Bids.

b. Upon receipt by the District Representative of the Contractor's written approval of each payment estimate, the District Representative will certify physical completion of each bid item to the Owner, will recommend acceptance of the work, and will recommend payment to the Contractor of ninety percent (95%) of the final estimate. Payment recommendations for each Bid Item and final payment will be made at the District’s Board of Director’s meeting, subsequent to the date of the written approval of each payment estimate.

c. Thirty five calendar days after filing of the Notice of Completion, the Owner will pay to the Contractor the amount remaining after deduction of all prior payments and all amounts to be kept or retained under the provisions of the contract to satisfy claims by others.

d. If the Contractor disagrees with the District Representative's final estimate and files a written statement of his claims, the District Representative will issue, as a semi final estimate, the proposed estimate submitted to the Contractor, and the Owner will make payment to the Contractor, in accordance with this Subsection. The District Representative in collaboration with the Engineer will then investigate the Contractor's claims, make any revisions to said semifinal estimates as they deem appropriate, and certify in writing to the Owner the amount and value of the work performed by the Contractor. The Owner will then make final payment to the Contractor.

V.7. Final Payment Terminates Liability of Owner

The acceptance by the Contractor of the final payment made under the terms of the Contract shall operate as, and shall be, a release to the Owner and its agents from all Claims of and/or liability to the Contractor for anything done or furnished for, or in relation to, the Work or for any act or neglect of the Owner or any person related to or affecting the Work, except for claims previously made in writing and identified as disputed by the Contractor at the time of the Contractor’s request for final payment.

V.8. Risk of Loss Prior to Final Acceptance

Except as set forth herein above relating to acts of God, all risk or loss from total or partial destruction of the work, or any part thereof, or any damage thereto, prior to final acceptance of the work by Owner, shall be borne by Contractor regardless of the cause of such total or partial damage or destruction. Contractor shall repair or replace such damages or destroyed property, at his sole cost, to its prior undamaged condition before being entitled to additional progress payments or final payment. Such total or partial destruction or damage shall not excuse Contractor from completion of the work in accordance with the provisions of the contract.

V.9. Right to Withhold Payments

a. In addition to all other rights and remedies of the District hereunder and by virtue of the law, the District may withhold or nullify the whole or any part of any partial or final payment to such extent as may reasonably be necessary to protect the District from loss on account of:

(1) Defective work not remedied, irrespective of when any such work was found to be defective;

(2) Claims or liens filed or reasonable evidence indicating probable filing of claims or liens including, but not limited to claims under Sections 1775, 1776, or 1777.7 of the Labor Code;



(3) Failure of the Contractor to make payments properly for labor, materials, equipment or other facilities, or to subcontractors and/or suppliers;

(4) A reasonable doubt that the work can be completed for the balance then unearned;

(5) A reasonable doubt that the Contractor will complete the work within the agreed time limits;

(6) Costs to the District resulting from failure of the Contractor to complete the work within the proper time;

(7) Damage to work or property.

b. Whenever the District shall, in accordance herewith, withhold any monies otherwise due the Contractor, written notice of the amount withheld and the reasons therefore will be given the Contractor. After the Contractor has corrected the enumerated deficiencies, the District will promptly pay to the Contractor the amount so withheld. When monies are withheld to protect the District against claims or liens of mechanics, material suppliers, Subcontractors, etc., the District may at its discretion permit the Contractor to deliver a surety bond in terms and amount satisfactory to the District, indemnifying the District against any loss or expense, and upon acceptance thereof by the District, the District shall release to the Contractor monies so withheld.

V. 10. Unpaid Claims

If, at any time prior to the expiration of the period for service of a stop notice, there is served upon the Owner a stop notice as provided in Sections 3183 and 3210 of the California Civil Code, pursuant to Section 3186 of the California Civil Code, the Owner shall, until the discharge thereof, withhold from the monies under its control so much of said monies due or to become due to the Contractor under this Contract as shall be sufficient to answer the claim stated in such stop notice and to provide for the reasonable cost of any litigation thereunder; provided, that if the District Representative shall, in its discretion, permit Contractor to file with the Owner the bond referred to in Section 3196 of the Civil Code of the State of California, said monies shall not thereafter be withheld on account of such stop notice.

VI. BONDS, INSURANCE, LEGAL RESPONSIBILITY, AND PUBLIC SAFETY

Contractor shall procure and maintain for the duration of the contract, insurance against claims for injuries to persons or damages to property which may arise from or in connection with the performance of the work hereunder by the Contractor, his agents, representatives, employees or subcontractors.

e. The policies are to contain, or be endorsed to contain, the following provisions:

B. The District may, at its discretion, have a representative at the fabricator’s facility during the fabrication of panels and

accessories. The Contractor shall notify the Engineer no less than two weeks in advance of starting fabrication so that

shop inspection may be arranged.

C. The majority of factory seams shall be machine5made with hot air or hot wedge welding techniques. Factory seams made

with adhesive shall be limited to those areas where machine5made seams are not practical. Machine5made factory seams and

adhesive factory seams shall be as shown on the Drawings.

D. Factory seams shall develop a minimum of 90% of the specified tensile strength of the parent material, when tested in

accordance with ASTM D751. All factory seams shall provide a bond between sheets sufficiently strong that failure of the

seam will not occur in the plane of the bonded surface.

E. Factory seams shall be fully bonded on the top side, including encapsulated edges so that no loose edge is present on the

top side of the fabricated panel.

F. All factory5fabricated panels shall be fabricated such that the materials are rolled. Accordion folded panels shall not be

permitted. Roll widths shall be not less than 30 feet nominal, (6) 615inch wide roll stock widths. “Wall papering” the

installation with manufacturer roll stock material shall not be permitted.

will not be permitted in either outside edge of a panel. Both longitudinal outside sides of panels shall be fabricated from a

single and continuous roll stock material, without rollstock splices. Rollstock splices shall only be permitted in the center

rolls of fabricated panels.

I. All factory seams shall be staggered as required to ensure that no more than 3 layers of geomembrane meet at a joint.

J. Where 3 layers of liner material occur at a "T" joint (factory rollstock splices), care shall be taken to seal the small leak

path that would otherwise occur along the edge of the middle layer. An unreinforced CSPE wedge shall be adhesively

applied to plug the potential leak path along the middle layer. The CSPE wedge shall extend for a distance of 6 inches from

the edge of the seam, as shown on the Drawings. The upper liner layer shall be heated and rolled to conform or "step5down"

3 5 Execution (peel strength, breakaway peel strength, and tensile strength). The shop seam verification testing shall be

performed by in5house personnel or independent laboratory. The Contractor shall submit the daily calibration test results

to the Engineer as part of the final quality assurance report. No shop seaming shall be performed until all test samples

have been tested and passed.



PART 3 EXECUTION

3.01 PREPARATION

A. Protection

1. Under no circumstances shall the CSPE geomembrane liner be subjected to rough treatment or have sandbags,

equipment, or other material dragged across its surface. Neither materials nor workers shall slide down slopes on top of

the geomembrane liner.

2. Scuffed surfaces resulting from abuse of any kind by the Contractor, the Engineer personnel overseeing the work, or

others, shall be repaired by the Contractor in accordance with the Specifications.

3. All persons walking on the geomembrane liner material shall wear smooth rubber5soled shoes. Shoes with patterns in

relief (like those popularly known as "sneakers") that could pick up rocks and debris will not be permitted.

4. The Contractor shall protect the new geomembrane liner by deploying a 24 ounce nonwoven geotextile in all high foot

traffic areas. This provision shall be included in the Contractor’s Quality Assurance Plan.

5. Scissors used in the Work shall have blades with rounded points. Marking pens or pencils used for identifying areas

requiring work shall not contain wax, oil, or grease.

6. Tarpaulins of CSPE material, about 10 feet by 10 feet in size, shall be spread out on the geomembrane liner material,

as a work area for seaming, preparing patches, storing tools, supplies, or rags. Under no circumstances shall gasoline or

diesel driven engines or cans of fuel be placed directly on the geomembrane liner or be stored within the reservoir

overnight. Buckets containing solvent and cleaning agents for use by the seaming crew(s) shall be plastic, the exterior of

which shall be clean and dry and shall not be stored within the reservoir overnight.

7. No wheeled vehicles will be permitted on the geomembrane liner. Miscellaneous equipment with pneumatic tires may

be permitted, with the prior written approval from the Engineer.

8. The Contractor shall place the CSPE geomembrane liner over the composite drainage course in such a manner to

ensure:

a. The underlying composite drainage course is not displaced or damaged.

b. The CSPE geomembrane liner is installed past the toe of slope and in a manner to prevent bridging at the toe of slope.

c. No additional tensile stresses (other than gravity induced self weight) are induced on the composite drainage course or

the CSPE geomembrane liner.

B. Surface Preparation

1. The cleaning of the underlying surface shall keep pace with the deployment of geomembrane liner materials. No

geomembrane liner materials shall be deployed until the underlying surface has been cleaned and approved by the

Engineer for deployment. The underlying surface shall be cleaned no more than 2 days in advance of material

deployment. This timeframe may be shortened, as determined by the Engineer, under less than ideal weather conditions.

2. Prior to the installation of the CSPE reservoir geomembrane liner, the Contractor shall inspect and clean the top

geotextile fabric of the composite drainage course. All foreign matter, debris, trash, rocks, and any other materials that

may potentially damage the composite drainage course or the geomembrane liner shall be removed or treated as directed

by the Engineer.

3. The Contractor shall conduct his Work to minimize the movement of fugitive dusts from the site boundaries by using

suitable Reasonably Available Control Measures (RACM).

3.02 INSTALLATION

A. Application

1. The Contractor shall identify and repair any damage or defects to panels that occurred during shipping, unloading,

storage, and installation.



2. Geomembrane liner panels shall be carefully placed on the slopes and bottom of the reservoir in accordance with

approved shop drawings and with minimum handling.

3. During installation of the geomembrane liner, the Engineer shall have complete authority to order an immediate stoppage

of the Work due to inclement weather, the use of improper installation procedures, or for any reason, which in his absolute

discretion, may result in a defective geomembrane liner.

4. Only those panels of geomembrane liner material that can be anchored, sealed, and seamed together in the same day

shall be unpackaged and placed in position.

5. Geomembrane liner panels shall be deployed in sufficient time to allow panels to shrink, as a result of panel stretch

during the manufacturing and/or fabrication process, prior to field seaming. The Contractor shall account for the panel

stretch during the manufacturing process when ordering panel lengths.

6. Bridging of geomembrane liner materials at the bottom of slope shall not be accepted. The geomembrane liner materials

shall be continuously supported and in direct contact with the underlying layers. The Contractor shall provide adequate

temporary ballast at the bottom of slope to prevent bridging.

7. Prior to punching holes in an individual geomembrane liner panel to attach it to the anchor studs and prior to seaming it

to previously installed adjacent panels, the Contractor shall straighten and pull taut the panel being installed. If seaming

equipment lifts the material off the substrate and leaves slack material along the seam, wherever possible the wrinkle so

formed shall also be pulled out before the material is punched for anchor studs or seamed to adjacent panels.

B. Temporary Anchorage

1. Sandbags shall be used as required to hold the geomembrane liner material in position during installation of the

geomembrane liner and to protect it from damage, displacement, and bridging.

2. During any discontinuity of the Work exceeding one hour in length, the leading (unseamed) edges of all panels or sheets

shall be secured with sandbags at not more than 35feet on center. The Contractor shall be responsible for maintaining closer

spacing as required to protect the Work during all weather conditions.

3. All sandbags placed on the reservoir side slopes shall be tied off to the perimeter curb at the top of slope to insure against

their shifting or sliding down the slope.

4. Bags that are split, torn, or otherwise losing their contents shall be immediately removed from the reservoir area and any

spillage immediately cleaned up.

C. Heat Seaming

1. Machine5made heat seams shall be used on all field seams wherever practical.

2. Heat seams shall be made using hot air or hot wedge welding equipment. All machine heat seaming equipment shall be

equipped with gauges which monitor voltage and temperature.

3. Hand5held heat seaming equipment may be used where machine5made heat seams are not practical and for miscellaneous

seaming, as approved by the Engineer.

4. Heat seaming shall comply with the Contractor’s approved Quality Assurance Plan.

5. Contact surfaces of geomembrane material to be seamed shall be wiped clean with a cloth until all foreign matter, dust,

and dirt has been removed. Only clean, white, lint5free, cotton cloths shall be used in the Work. Cleaning of contact

surfaces shall not be completed more than 10 minutes ahead of seaming. When conditions are adverse to proper

workmanship, such as high heat or winds, or when other conditions increase the probability of dirt or other foreign material

being deposited on the contact surfaces, the time between cleaning and seaming shall be reduced as necessary to produce

acceptable seams.

6. The Contractor shall follow immediately behind the heat seaming equipment, while the material is still hot from the

initial seam, bonding the top edge of the seam. The top edge of the seam shall be “stitched” by manually rolling the seam

area with firm pressure with a 25inch wide roller.

7. In the event a CSPE panel has been laid out and not seamed for a period of 3 days or more, the contact surfaces shall be

solvent scoured and buffed to ensure a positive bond at the seam. The scouring procedure shall consist of hand



buffing the contact surfaces with stainless steel scouring pads soaked in solvent to effectively penetrate and remove the

oxidation layer. This scouring procedure shall be applicable to all panel5to5panel seams, patches, and seams for attachment of

accessories.

D. Adhesive Seaming

1. Adhesive may be used to make seams where heat seaming is impractical and for minor repairs, as approved by the

Engineer.

2. Adhesive seaming shall comply with the manufacturer’s recommendations and the Contractor’s approved Quality

Assurance Plan.

3. Use of adhesives and solvents shall be in compliance with the applicable regulatory requirements.

4. Contact surfaces of geomembrane material to be seamed shall be wiped with a cloth until all foreign matter, dust, and dirt

have been removed. Contact surfaces shall then be washed with clean cloths soaked with solvent to remove surface cure.

Only clean, white, lint5free, cotton cloths shall be used in the Work. When a cloth is more colored than white, it shall be

removed and replaced. Surface cure is removed when the CSPE turns shiny and slick when wet and dull when dry. Removal

of surface cure shall not be completed more than 10 minutes ahead of seaming. When conditions are adverse to proper

workmanship, such as high heat or winds, or when other conditions increase the probability of dirt or other foreign material

being deposited on the contact surfaces, the time between washing and seaming may be reduced as necessary to produce

acceptable seams.

5. Immediately before seaming, the contact surfaces of the liner material shall be heated to a warm (100ºF minimum) and dry

condition with an electric heat gun, in accordance with the manufacturer’s printed recommendations.

6. Adhesive shall be liberally applied, by brush or roller, to one of the contact surfaces over a length of approximately 2 feet

and the two contact surfaces shall then be immediately brought together. Adhesive shall be glistening with the appearance of

moisture at the time the contact surfaces are brought together, without any sign of drying (surface skinning). In applying the

adhesive, care shall be taken to "tie5in" to the end of the seam previously completed so

that leak paths or weak points in the seam do not occur at seam start and stop increments.

7. As soon as the contact surfaces are brought together, the seam shall be “stitched” by manually rolling the seam area with a

25inch wide roller in a direction perpendicular to the seam, with firm pressure. A small amount of adhesive shall extrude and

appear at the top edge of the seam to indicate that a sufficient amount of adhesive has been applied.

8. In the event a CSPE panel has been laid out and not seamed for a period of 3 days or more, the contact surfaces shall be

solvent scoured and buffed to ensure a positive bond at the seam. The scouring procedure shall consist of hand buffing the

contact surfaces with stainless steel scouring pads soaked in solvent to effectively penetrate and remove the oxidation layer.

This scouring procedure shall be applicable to all panel5to5panel seams, patches, and seams for attachment of accessories.

E. Joinings

1. Panels to be joined in the field shall be lapped as shown on the Drawings. After the initial seal of the lap joint has been

made, all exposed free edges of the geomembrane liner material shall be resealed, using the same procedure, to eliminate all

free edges. The top edge of all seams shall be fully bonded. Loose edges will not be allowed on the top side of the reservoir

geomembrane liner.

2. Butt joints shall be used only where lap joints are not possible and as approved by the Engineer. Butt joints shall be

formed using joint cover strips made from the same fabric5reinforced geomembrane liner material, continuous in length, and

as shown on the Drawings. The joint cover strip shall be centered over the butt joint and shall be fully bonded across its

entire width. Butt joints shall be installed in accordance with the same procedures for lap joints specified herein.

3. All seams, field and factory, shall be staggered a minimum of 12 inches to ensure that no more than 3 layers of material

meet at a joint.



4. Where 3 layers of liner material occur at a "T" joint (field seams, factory seams, and rollstock splices), care shall be taken

to seal the small leak path that would otherwise occur along the edge of the middle layer. An unreinforced CSPE wedge shall

be adhesively applied to plug the potential leak path along the middle layer. The CSPE wedge shall extend for a distance of 6

inches from the edge of the seam, as shown on the Drawings. The upper liner layer shall be heated and rolled to conform or

"step5down" transition and seal the leak path. In addition, the area shall be solvent wiped and sealed with a high5solids

adhesive and then covered with a 4 inch wide 405mil unreinforced CSPE cap strip. The cap strip shall be fully bonded and

centered on edge of the top geomembrane layer.

5. Except where specifically stated, all field seams shall be covered with a fully bonded 405mil unreinforced CSPE cap

strip, as shown on the Drawings. The cap strip shall be fully bonded and centered on edge of the top geomembrane layer.

6. Care shall be taken to avoid fishmouths, wrinkles, pleats, folds, and tucks in seams. Any such defects shall be prevented

by tugging on the seam just completed in the opposite direction from which the seam is progressing, during the seaming

process. The Contractor’s seaming crew shall give continuous attention to the elimination of all

such defects to prevent their occurrence. Regardless of the location or cause of such defects, they shall be slit out far enough

from the seam to dissipate the defect. The slit edges shall then be lapped and field seamed. Wherever the

lap width is less than 4 inches, the defect shall be repaired with a joint cover strip made from the same fabric5 reinforced

material as the liner.

7. The Contractor shall take the necessary precautionary measures to ensure the geomembrane liner is not bonded to the

underlying composite drainage course during the seaming process.

8. Where fabric5reinforced CSPE has been cut and thus exposes the fabric, the cut edge shall be capped with a 405mil

unreinforced CSPE, and as shown on the Drawings. Specifically, the acceptable treatment options for the cut and exposed

fabric at the various locations shall conform to the following table:

9. Field seams shall not be made if the ambient temperature or humidity would result in inferior seams.

F. Anchorage

1. The geomembrane liner material shall be anchored at the perimeter concrete anchor curb and other reservoir concrete

structures as shown on the Drawings.

2. The geomembrane liner material at the top of slope anchor curb shall be installed on the anchor studs by either of the

following methods:

a. Anchor bolt holes shall be neatly punched using a tool that removes the material to form a neat hole 1/85inch less in

diameter than the penetrating stud diameter. The geomembrane liner material shall be forced over the stud in such a

manner to prevent damage to the liner material or the stud.



b. The solid geomembrane liner material may be forced onto the anchor studs using a pipe section with an inside diameter

slightly larger than the anchor stud diameter (½5inch, schedule 40 pipe for ½5inch anchor studs), thus punching the

geomembrane liner material around the anchor stud. This method will result in no removal of geomembrane liner material

at the anchor bolts. Precutting or slicing the liner material prior to attachment onto anchor studs shall not be permitted.

3. Anchor bolt holes in the liner and attachment strip geomembrane material at underwater seals to structures and all other

holes for anchor studs shall be neatly punched using a tool that removes the material to form a neat hole 1/85 inch less in

diameter than the penetrating stud diameter. The geomembrane liner material shall be forced over the stud in such a manner

to prevent damage to the geomembrane liner material or the stud.

4. Oversized, cut, or irregular shaped holes will not be allowed.

5. Anchor bolt holes created by any other means shall not be accepted, unless specifically approved by the Engineer.

6. Seams in the liner attachment strip underneath the flat bar at underwater seals to structures shall be minimized to the

maximum extent possible. Seams shall be butt joints with joint cover strips and with no gaps, as shown on the Drawings. Lap

seams at underwater seals to structures shall not be permitted under the batten bar. An extruded unreinforced CSPE wedge, as

shown on the Drawings, shall be applied at joint cover strip step down locations to provide continuous bearing on the gasket

and liner attachment strip.

G. Anchor Studs:

1. All holes for studs to be set with concrete adhesive anchors shall be drilled normal to the concrete surface and shall be

accurately spaced to the dimensions shown on the Drawings. The Contractor shall use jigs and templates as required to

B. Thinners: Only thinners recommended and furnished by the chosen coating

manufacturer shall be used to thin the paint products.

C. Priming Inaccessible Areas: Should any areas exist where the intersection of two

members does not allow the complete cleaning of the intersection and the members

cannot be separated for cleaning, after the initial priming these intersections shall be

primed with a material suitable for marginally cleaned surfaces. The material shall be

recommended by the manufacturer of the exterior paint system and shall be as follows:

1. Sherwin1Williams Epoxy Mastic,

2. Tnemec 135 Chembuild,

3. or other material favorably reviewed in writing by the Engineer.


PART 3 – EXECUTION

3.01: DESCRIPTION OF WORK

A. The Contractor shall remove the existing steel access ladder and transport to an approved facility for metal

repair, media blasting, cleaning and recoating as directed by the Engineer. After the ladder is removed, the

Engineer shall inspect the existing anchor bolts and fasteners to determine their suitability for reuse. If required,

the Engineer shall direct the contractor to replace anchor bolts and/or repair the ladder fastener system, as

deemed appropriate by the Engineer. Upon completion of the repair and recoating process, the Contractor shall

reinstall the access ladder in the original location.

3.1. SURFACE PREPARATION

A. All surface preparation shall be done in workmanlike manner and in a shop which is fully certified and in

compliance with applicable environmental regulations.

B. Preparation:

1. Burrs, weld spatter, sharp edges, corners or rough welds which would cause difficulty in achieving a defect1

free coating shall be chipped or ground smooth.

2. It is not the intent to have the welds or scars chipped and/or ground flush. The objective of the chipping

and/or grinding is to eliminate sharp edges, corners, and overlaps in order to provide a surface for the

application of a uniform thickness coating without voids.

3. These chipped and/or ground areas shall be cleaned to provide the proper surface profile for the paint.

C. Surface Preparation: All exterior surfaces shall be cleaned to SSPC1SP6, Commercial Blast1Cleaning

(modified).

D. Surface Contamination: The surfaces to be painted shall be free from mud, oil, grease, dust, moisture,

halides, or other foreign material which would cause adhesion problems. If the Engineer finds questionable

amounts of contamination on the steel surfaces or painted surfaces to be topcoated, a representative of the home

office of the paint manufacturer may be called to examine the surfaces in question and assist in determining if

the surfaces are in accordance with these Specifications and the manufacturer's recommendations.

3.2. APPLICATION

A. All painting shall be done in a professional manner.

B. Priming:

1. Not later than during the same day and before the formation of rust, the cleaned exterior surfaces (SSPC1SP6

1 modified) shall be primed with the specified primer.

2. Stripe Coat: After the application of the first coat, all seams, edges, lapped joints, rough areas, bolt heads and

nuts, remains of erection lugs and scars, corners, member intersections, and other deviations from smooth

surfaces shall be primed by brush and/or roller using 10% thinned material in a contrasting color to the primer.

The 10% thinned material shall be worked sufficiently into all cracks, crevices, and seams. Initial spray

application of this stripe coat shall not be permitted.

3. The primer shall not be applied closer than 6 in. to an uncleaned surface.

C. Priming Inaccessible Areas: If the intersection of two members does not allow the complete cleaning of the

intersection and the members cannot be separated for cleaning, after the initial priming these intersections shall

be primed with the material specified in this Section.


D. Intermediate Coat: After adequate curing of the prime coat, all primed exterior surfaces shall be given a full

intermediate coat of the specified paint. The color shall be slightly darker than that chosen for the finish coat,

being dark enough to visually assure application of the finish coat, and light enough to allow proper hiding. (An

intermediate coat lighter than the finish coat shall not be permitted due to the inability to distinguish between the

lighter intermediate and the highlights of the finish.) The coating manufacturer shall recommend a darker color

for the intermediate coat and this color shall be submitted for review.

E. Finish Coat: After adequate curing of the intermediate coat, the entire exterior surfaces shall then be given a

final coat of the selected paint in the color selected by the District.

3.3 CLEANING

A. During the progress of the work, discarded materials, rubbish, cans, and rags shall be removed at the end

of each day's work.

B. Brushes and other application equipment shall be thoroughly cleaned at the end of each period of

use and when changing to another paint or color.

C. Upon completion of painting work, masking tape, tarps, and other protective materials shall be removed

using care not to scratch or otherwise damage finished surfaces.


A. The work performed as prescribed by this item will be included in the unit prices which are described

as follows:

1. Removal, Repair, Shop Recoating and Replacement of Existing Ladder shall be paid for per Lump Sum,

which price shall be full compensation for all work related to this work item and shall include all materials,

labor, tools, equipment, cleaning, and any other operations necessary for completion the work. The cost of

removal, and disposal of all materials resulting from this work shall be included in the unit prices stipulated

in the CONTRACTOR’S bid.

B. All other payments shall be made as per bid items. No payment shall be made for work considered incidental

or complimentary to a pay item already in bid. The contractor shall clarify, for his own benefit, all work

required for any item, incidental or otherwise, prior to bidding.
