INSTRUCTION TO BIDDERS

SCOPE OF WORK The Chesapeake Bay Bridge and Tunnel District (CBBT) has nine Communication Node Cabinets (CNC) and Lighting Unit Substations (LUS) on platforms suspended off of the bent caps on the northbound spans. The platforms are located on the west side of the northbound span, their location when the facility was originally built in the 1960s. The work for this project generally consists of relocating the CNC-LUS equipment from the west side platforms to the east side Emergency Pull Offs (EPO)s. This includes, but is not limited to:

Transformer Replacements: The existing LUS transformers are original equipment and expected to have Polychlorinated Biphenyls (PCB)s. They will be removed from the west platform and be properly disposed of in accordance with local, state and federal regulations. The LUSs will be replaced by new ones in the EPOs on the east side of north bound trestles. These LUSs will meet current standards and match those on the south bound structures. New wiring will be run to accommodate the new location.

Communication Node Cabinet replacement: The existing CNCs will have existing Program Logic Controller (PLC) panels and supporting hardware removed, with the cabinet and cooling unit being properly discarded. The new CNCs will be installed in the EPOs on the east side of north bound trestles, with the PLC panels and supporting hardware being reused.

Lighting Circuit Rewiring: The existing light circuit wiring is original wiring (over 50 years old) and is beyond its useful life and does not meet current code requirements. The project will upgrade all of the light circuit wiring on the northbound trestles.

Light Fixture Replacement: The trestle High Pressure Sodium (HPS) light fixtures will be replaced with Light Emitting Diodes (LED), during the rewiring operation.

Unused Device and Cable Removal: Unused signals, phones and miscellaneous equipment and cabling will be removed from the north bound trestles.

Sign and Signal Wiring: The remaining sign and signal wiring shall be replaced on the north bound trestles.


ii

Load Center Upgrades: As part of the relocation and rewiring, the load center and power

panels will be replaced with equipment that meets current codes and matches the equipment on the southbound trestle.

Fiber Optic Cable: Install a new 48 strand fiber optic cable across the northbound span and remove the existing fiber optic cable, ranging from 12 to 24 strand.

Generators: The existing configuration locates a generator on each existing platform. These will be removed, with the new locations not being equipped with a generator. The new locations in the EPOs, on the east side of the northbound trestles, will be equipped to receive power from a portable generator parked in the EPO as needed in the event of an equipment failure.

The new and existing CNC-LUS equipment is critical to the safe operation of the Chesapeake

Bay Bridge Tunnel. Unscheduled outages will not be permitted. Should any unscheduled

outages result from the Contractors actions, the Contractor shall work continuously, making

repairs as soon as possible, to restore full functionality.

a joint venture under the same or different name. A Bid submitted by an affiliate of an individual, partnership, corporation or any party of a joint venture will be considered as more than one Bid submitted for the same work.

Affiliate as used here is defined as: Any business entity which is closely associated to

another business entity so that one has the power to control the other either directly or indirectly; or, when a third party has the power to control both: or, where one business entity has been so closely allied with another through an established course of dealings, including but not limited to the lending of financial wherewithal or engaging in joint ventures, so as to cause a public perception that the two are one entity.

b. Evidence of collusion among Bidders. c. Incompetency or inadequate machinery, plants, or other equipment as revealed by the

Bidder’s financial and experience statements required by these Specifications. d. Unsatisfactory workmanship or progress as demonstrated by performance records of

current or past work for other agencies or departments of the Commonwealth of Virginia, or agencies or departments of other states in the United States or the federal government.

e. Failure to comply with any prequalification regulation of the District. A Bid from a non-

prequalified Bidder will be automatically rejected.

SECTION 103 - AWARD AND EXECUTION OF CONTRACT Sec. 103.01 - Consideration of Bids After Bids have been opened and read, they will be compared on the basis of the summation of the products of the approximate quantities shown in the Bid schedule and the unit Bid prices. The District may correct arithmetical errors in the Bid prior to such comparisons. The District reserves the right, in its sole discretion, to reject, reschedule, or cancel the solicitation of any or all Bids, to waive technicalities for any or every Bidder, to accept or reject any or all items of Bid, to accept other than the lowest Bid based upon the aforementioned criteria, to advertise for new Bids, or proceed to do the work otherwise if it deems that the best interest of the District would be promoted thereby.


GP-13

Sec. 103.02 - Award of Contract If the Contract is awarded, the Award will be made to the lowest responsive and responsible Bidder. In determining the successful Bidder, the following factors shall be considered: a. Contract Bid price. b. Ability, capability, and skills of the Bidder to perform the Contract Work. c. Whether the Bidder can perform the Contract Work promptly and within the time frame

An approved Contract executed by the District is required before the District is bound. An Award may be cancelled any time by the District prior to execution in order to protect the public interest, the integrity of the bidding process or for any other reason if, in the judgment of the District, the best interests of the District will be promoted thereby. The Award Date will not be later than midnight of the 60th day after the opening of the Bids, except by mutual consent of the District and the Bidder as set forth below. If the District has not awarded the Contract within this period, the Bidder, upon written request, may withdraw the Bid without penalty or prejudice unless the time limit is extended by mutual consent of the District and the Bidder. If the Bidder withdraws the Bid due to conditions as prescribed herewith, the District reserves the right to either re-advertise and re-bid the Contract, award the Contract to the next lowest responsible and responsive Bidder who does not withdraw the Bid, or otherwise proceed, as the District may decide. Sec. 103.03 - Cancellation of Award The District may cancel the Award of any Contract at any time before the execution of the Contract by all parties without liability to the District.


GP-14

Sec. 103.04 - Return of Bid Guaranty Bid Guaranties, except for the two lowest Bidders, will be returned immediately after the examination of Bids. The Bid Guaranties of the two lowest Bidders will be held by the District and will be returned within 5 days after a satisfactory performance bond has been furnished and the Contractor has been awarded and duly executed between all parties. When a Bidder withdraws his Bid prior to Award, after being selected as the low Bidder, the Bid Bond will be forfeited in accordance with the requirements of Section 11-57 of the Code of Virginia. Sec. 103.05 - Performance and Payment Bonds a. For all contracts exceeding $100,000 and within 15 Calendar Days after notification by

1. A performance bond in the sum of the Contract amount, conditioned upon the

faithful performance of the Contract, in strict conformity with Contract Documents.

2. A payment bond in the sum of the Contract amount. Such bond shall be for the

protection of the claimants who have and fulfill contracts to supply labor and materials to the prime Contractor to whom the Contract was awarded, or to any Subcontractors, in the prosecution of the work provided for in such Contract, and shall be conditioned upon the prompt payment for all such material furnished or labor supplied or performed in the prosecution of the work. "Labor and materials" shall include public utility services and reasonable rentals of equipment, but only for periods when the equipment rented is actually used at the site.

b. Each of such bonds shall be satisfactory in form and substance to the District and must be

executed by one or more surety companies selected by the Contractor which are legally authorized to do business in the Commonwealth of Virginia and which are otherwise acceptable to the District. In order to be considered properly executed, the bonds shall include authorized signatures and titles.

Final execution of the Contract is effective after the documents contained in the Bid have been determined acceptable by the District, and the Bid has been signed by the District. No Contract shall be considered effective until it has been fully executed by all parties. Sec. 103.08 - Failure to Furnish Bonds or Certificates of Insurance Failure by the successful Bidder to furnish the District with acceptable bonds or Certificates of Insurance within fifteen (15) Calendar Days after being notified of the Award of the Contract, shall be just cause for the cancellation of the Award and forfeiture of the Bid Guaranty which shall become the property of the District, not as a penalty, but in liquidation of the damages sustained.

GP-16

SECTION 104 - SCOPE OF WORK Sec. 104.01 - Intent of Contract The intent of the Contract is to provide for the completion in every detail of the work described therein. Sec. 104.02 - Modification of the Contract The District reserves the right to make, in writing, at any time during the progress of the work, such changes in quantities and such alterations in the work as may be found to be necessary or desirable to satisfactorily complete the Project. Such changes in quantities and alterations shall not invalidate the Contract nor release the surety, and the Contractor agrees to perform the work as altered. If the alterations or changes in quantities significantly change the character of the work under the Contract, whether or not changed by any such different quantities or alterations, an adjustment, excluding anticipated profits, will be made to the Contract. The basis for the adjustment shall be agreed upon prior to the performance of the work. If a basis cannot be agreed upon, then an adjustment will be made either for or against the Contractor in such amount as the Engineer may determine to be fair and equitable. In the event the altered or added work is of sufficient magnitude or complexity to require additional time to complete the Project, an adjustment in Contract Time will be made in accordance with the provisions of Section 108.07. At the option of the Engineer, the Contractor may be directed to accomplish the work on a force account basis in accordance with the requirements of Section 109.03. If the alterations or changes in quantities do not significantly change the character of the work to be performed under the Contract, the altered work will be paid for as provided elsewhere in the Contract. The term “significant change” shall be construed to apply only to the following circumstances: a. When the character of the work as altered differs materially in kind or nature from that

involved or included in the original proposed construction or b. When an item or work is increased or decreased more than 25 percent of the original

Contract quantity. Any allowance for an increase in quantity shall apply only to that portion in excess of 125 percent of original; Contract item quantity, or in case of a decrease below 75 percent, to the actual amount of work performed.

Sec. 104.03 - Extra Work The Contractor shall perform unforeseen work, for which there is no price included in the Contract, when the District deems it necessary or desirable in order to complete the work. The


GP-17

District and Contractor shall negotiate an equitable work order to cover such work. If unable to reach agreement, the work shall be performed in accordance with the provisions provided under Section 109.03. No claim for extra work will be allowed by the District unless such work is ordered in writing by the Engineer. Any such work or material which may be done or furnished by the Contractor without such written order first being given shall be at the Contractor’s risk and expense, and the Contractor hereby covenants and agrees that without such written order he shall make no claim for compensation for work or material so done or furnished. Sec. 104.04 - Maintenance During Construction Maintenance of Roadway or Structure: The Contractor shall maintain the work from the beginning of construction operations until final acceptance of the Project. This maintenance shall constitute continuous and effective work prosecuted day by day with adequate equipment and forces to the end that the roadway, structures, island surface, or other facilities, are kept in satisfactory condition at all times. The Contractor shall keep the portions of the facility being used by the public free from irregularities and obstructions of any character which might present a hazard or annoyance to traffic and in such condition that traffic will be adequately accommodated, and in such condition acceptable to the District. Failure on the part of the Contractor, at any time, to comply with these provisions will result in the Engineer or District Representative notifying the Contractor to comply with the required maintenance provisions. In the event the Contractor fails to remedy unsatisfactory maintenance immediately after receipt of such notice, the Engineer may proceed with adequate forces, equipment, and material to maintain the Project, and the entire cost of the maintenance, plus 25% for supervisory and administrative personnel, will be deducted from monies due the Contractor on his Contract. Sec. 104.05 - Cleanup Removal from the Project of rubbish, scrap material, and debris caused by the Contractor's personnel or construction operations shall be a continuing process throughout the course of the work so that the work site will present a neat, orderly, and workmanlike appearance at all times. The Contractor will not be allowed to waste any such rubbish or debris over the side of the bridges or trestles into the Chesapeake Bay, or other waters, nor unto the stone protection around the perimeter of the islands, nor unto any of the District's property. The Contractor indemnifies and holds the District harmless from all claims, costs and expenses (including, but not limited to, remediation or removal claims, costs and expenses and claims, costs and expenses resulting from injury to persons, property or the environment) in connection with any removal or disposal of any rubbish, scrap material or debris not otherwise complying with the requirements of this Section. Any claims, costs or expenses that are incurred by the District, may be deducted by the District for monies due the Contractor under the Project. Before final acceptance, all parts of the work, including all spaces occupied by, or affected by, the Contractor during the course of the Contract Work, shall be cleaned of any rubbish, surplus


GP-18

materials, equipment, incidentals, and temporary structures and appurtenances. All parts of the work shall be left in a neat and orderly condition. All costs in connection herewith shall be at the Contractor’s expense.

SECTION 105 - CONTROL OF WORK Sec. 105.01 - Authority of the Engineer During the prosecution of the work, the Engineer will answer all questions which may arise as to the quantity, quality, and acceptability of materials furnished and work performed; the rate of progress of the work; the interpretation of the Contract Documents; the acceptable fulfillment of the Contract by the Contractor; disputes and mutual rights between contractors; and compensation. The Engineer has the authority to suspend the work wholly or in part if the Contractor fails to correct conditions that are unsafe for the workers or the general public; or for failure to carry out provisions of the Contract. The Engineer may also suspend work for such periods as may be necessary due to emergencies on the facility or because of unsuitable weather affecting the safety of the general public in accordance with the provisions of Section 108.08; for conditions considered unsuitable for prosecution of the work; or for any other condition or reason deemed to be in the public interest. Sec. 105.02 - Plans and Working Drawings Plans consisting of general drawings and showing such details as are necessary to give an understanding of the work specified are furnished by the District. Except as otherwise shown on the Plans, dimensions shown on the Plans are measured in the respective horizontal or vertical planes. Dimensions that are affected by gradients or vertical curves shall be adjusted as necessary to accommodate actual field conditions and shall be specifically denoted on the working drawings. Where the Contract Work interfaces with the existing facility components, the Contractor is expected to field verify and otherwise apprise himself of actual field conditions that might affect his work. The Contractor shall furnish such working and detail drawings as may be required and as specified for this Project. Working and shop drawings shall not incorporate any changes from the requirements of the Contract unless the changes are specifically denoted, together with justification, and are approved in writing by the District. Seven (7) sets of such submittals shall be made to the District for review in sufficient time to allow for review, discussion and correction prior to beginning the work they reference. Each drawing submittal, including those of Subcontractors and suppliers, shall be stamped with the Contractor's approval indicating his review and concurrence with the working or detail drawing. Work performed and material ordered prior to review is at the Contractor's risk. One set will be returned to the Contractor duly marked with comments, or marked approved within 30 Calendar Days after receipt from the Contractor. If not marked approved, such submittals shall be revised as necessary by the Contractor and seven (7) revised sets, duly stamped by the Contractor, shall


GP-19

be resubmitted for District review and approval. Upon being marked approved, the Contractor shall submit to the District for distribution one reproducible and four prints of the approved submittals. Upon completion of the work, the Contractor shall supply the original approved submittals to the District. It is expressly understood that the review by the District of the Contractor's working drawings relates to the conformance with Contract Documents. Such review shall not be considered as authorization for any deviation from Plans or Specifications unless the deviation is specifically described including explicit supporting justification, nor will such review relieve the Contractor from responsibility for errors in such drawings. In the event working drawings, which define the change(s) initiated by the Contractor, require more than two (2) resubmissions or revisions, the cost of additional reviews by the District, the Engineer, or the Engineer's designated representative will be borne by the Contractor. The Contractor shall also submit copies of catalog cuts or similar product data following the same procedure outlined for working drawings. The Contractor may authorize the fabricator in writing to act for the Contractor in matters relating to working drawings. Such authorization shall have the force and effect of any other representative of the Contractor’s organization. The cost of working drawings furnished by the Contractor shall be included in the cost of appropriate Bid items. Sec. 105.03 - Coordination of Plans, General Provisions, Special Provisions and Technical Specifications The Plans, General Provisions, Special Provisions, Technical Specifications, and all supplementary documents are essential parts of the Contract. A requirement occurring in one is as binding as though occurring in all. They are intended to be complementary and to describe and provide for a complete work. In case of a discrepancy, the following will apply: a. Calculated dimensions, unless obviously incorrect, will govern over scaled dimensions.

b. Technical Specifications will govern over these General Provisions and the Standard

Specifications. c. Plans will govern over these General Provisions, Standard Specifications and Technical

Specifications. d. Special Provisions (if required) will govern over the Plans, General Provisions, Standard

Specifications and the Technical Specifications. The Contractor shall take no advantage of any apparent error, discrepancy, or omission in the Plans or Specifications. In the event the Contractor discovers such an error, discrepancy, or omission, he shall immediately notify the Engineer in writing. The Engineer will then make such corrections and interpretations as may be deemed necessary for fulfilling the intent of the Contract.


GP-20

Sec. 105.04 - Cooperation by Contractor The Contractor shall give the work the constant attention necessary to facilitate the progress thereof and shall cooperate with the District, representatives of the District, and other contractors, if applicable, in every way possible. The Contractor shall have on the Project at all times a competent superintendent capable of reading and understanding the Plans and Specifications and experienced in the type of work being performed who shall receive instructions from the Engineer or his authorized representatives. The superintendent shall understand and speak fluent English. The superintendent shall have full authority to execute the orders and directions of the Engineer without delay and supply promptly such materials, equipment, tools, labor, and incidentals as may be required. Sec. 105.05 - Holidays Work on Sundays, the below listed holidays, and the normal work day preceding and following these holidays will not be permitted without written permission from the Engineer: (1) January 1; (2) Easter; (3) Memorial Day; (4) July 4; (5) Labor Day; (6) Thanksgiving Day; and (7) Christmas Day. If any of these holidays occur on Sunday, the following Monday shall be considered as the holiday. If occurring on Saturday, the preceding Friday will be considered as the holiday. The District may waive, with written request within 72 hours, the restriction of working on days preceding and following the above listed holidays and Sundays when the Contractor’s operations have no effect on vehicular traffic, when determined by the District. Sec. 105.06 - Authority and Duties of the District Representative Representatives employed by the District are authorized to inspect all work performed and all material and equipment furnished. Inspection may extend to all or any part of the work and to the preparation, fabrication, or manufacture of the materials and equipment to be incorporated into the work. The District representative is not authorized to alter or waive the provisions of these Specifications or to make changes in the Plans. The District representative is placed at the site of the work to keep the District informed as to its progress and the manner in which it is being performed. He will endeavor to call to the attention of the Contractor any nonconformance with the Contract Documents. He is not authorized to make a final acceptance of the work or any part of it, to approve any operation or item, to issue instructions contrary to the Contract Documents, or to act as a foreman for the Contractor. The representative will have authority to reject defective work, material and equipment, and to suspend work which is being improperly performed, subject to the concurrence of the Engineer. Such inspection shall not relieve the Contractor of any obligation to furnish acceptable materials or to provide completed construction that is in strict accordance with the Plans and Specifications.


GP-21

The District representative will exercise additional authority only as may be delegated by the Engineer, who shall advise the Contractor in writing of such delegations of authority that will affect the work. Sec. 105.07 - Inspection of Work All materials and equipment and each part or detail of the work shall be subject to inspection by the Engineer. The Engineer shall be allowed access to all parts of the work and shall be furnished with such information and assistance by the Contractor as is required to make a complete and detailed inspection. The Engineer and his appointed representative shall have ready access to machines and plant equipment used in processing materials, manufacturing equipment or placing materials. If the Engineer requests it, the Contractor, at any time before final acceptance of the work, shall remove or uncover such portions of the finished work as directed. After examination, the Contractor shall restore said portions of the work to the requirements of the Contract Documents. Should the work that is exposed or examined be acceptable, the uncovering or removing, and the replacing of the covering or making good the parts removed, will be paid for as extra work in accordance with Section 104.03. Should the work so exposed or examined be unacceptable, the uncovering or removing, and the replacing of the covering or making good the parts removed, will be at the Contractor's expense. Prior to beginning work, the Engineer and the Contractor will meet and the Engineer will establish an understanding with the Contractor concerning the stages of work and Contractor operations which will require inspection by the District. In order for the Engineer to schedule inspection of the work, the Contractor shall keep the Engineer informed of planned operations in accordance with Section 103.06(d). Accordingly, any work done, materials used or equipment installed without said supervision or inspection by a District Representative may be ordered removed and replaced at the Contractor's expense, unless the District Representative failed to inspect after having been given reasonable notice in writing that the work was to be performed. When an inspection reveals that work has not been properly performed, the Contractor shall be so advised and shall immediately inform the District of his proposed plans, method and schedule for correcting such work, as well as when a re-inspection of such corrected work can be made. Any work which does not comply with the Contract Documents will be considered as unacceptable work. Such work shall be remedied or removed and replaced with acceptable work at the Contractor's expense. If the District informs the Contractor that certain work is unacceptable and is to be corrected, and the Contractor fails to comply, the District may cause the unacceptable work to be removed and replaced by others or by the District's own forces, and deduct the cost of such work from any monies due the Contractor.


GP-22

Sec. 105.08 - Removal of Unacceptable and Unauthorized Work Work that does not conform to the requirements of the Contract will be considered unacceptable work. Unacceptable work shall be remedied or removed immediately and replaced in an acceptable manner at the Contractor’s expense. The Engineer may accept the work at a reduced price when acceptance is considered to be in the best interest of the District. Work that is done contrary to the instructions of the Engineer, beyond the lines shown on the Plans or as designated by the Engineer except as specified herein, or without authority will be considered unauthorized and will not be paid for. Such work may be ordered removed or replaced at the Contractor’s expense. If the Contractor fails to comply immediately with any order of the Engineer made under the provisions of this section, the Engineer will have the authority to cause unacceptable work to be removed and replaced and unauthorized work to be removed and to deduct the cost from any monies due or to become due the Contractor. The Contractor shall not perform destructive sampling or testing of the work without written authorization of the Engineer. Unauthorized destructive sampling or testing will cause the work to be considered unacceptable. In the event the Contractor is granted authorization to perform destructive sampling or testing, the Engineer must approve the method and location of each test prior to beginning such sampling or testing. In addition, destructive sampling and testing shall be performed in the presence of the Engineer. The Contractor will not be entitled to any increase in time or payment regarding any work that must be removed, replaced, repaired, remedied, or uncovered if their costs are held to be expenses of the Contractor according to the terms of this Section. Sec. 105.09 - Acceptance

(a) Partial Acceptance: If at any time during the prosecution of the Project, the Contractor completes a unit or portion of the Project, such as work on a particular trestle, in its entirety, he may request that the Engineer make final inspection of such work. If the Engineer finds upon inspection that the work conforms to the requirements of the Contract, and that acceptance is in the best interest of the District, the work may be accepted as being completed, and the Contractor will be relieved of further responsibility for the work as specified in Section 107.07. Partial acceptance shall in no way void or alter any terms of the Contract. If any damage attributable to causes beyond the control of the Contractor is sustained by the accepted unit or portion of the Project, the Engineer may authorize the Contractor to


GP-23

make necessary repairs. In the absence of Contract prices covering the items of repair, the work will be paid for in accordance with the requirements of Section 109.03. (b) Final Acceptance: Upon receipt of written notice from the Contractor of presumptive completion of all work on the entire Contract, the Engineer will make an inspection. If all work specified in the Contract has been completed, the inspection will constitute the final inspection and the Engineer will make the final acceptance. The Contractor will be notified of final acceptance in writing within 5 days. If the inspection discloses that any work, in whole or in part, is incomplete or unacceptable, the Contractor shall immediately correct the deficiency. Upon completion or correction of the work, another inspection will be made that will constitute the final inspection. In such event, the Engineer will make the final acceptance and the Contractor will be notified of final acceptance in writing within 5 days. In any event, the Contractor shall maintain the Project until final acceptance except under conditions that may be specifically exempted.

Sec. 105.10 - Submission and Disposition of Claims Early or prior knowledge by the District of an existing or impending claim for damages could alter the plans, scheduling, or other action of the District or result in mitigation or elimination of the effect of the act objected to by the Contractor. Therefore, a written statement describing the act of omission or commission by the District or its agents that allegedly caused damage to the Contractor and the nature of the claimed damage shall be submitted to the Engineer at the time of occurrence or beginning of the work upon which the claim and subsequent action are based. If such damage is deemed certain in the opinion of the Contractor to result from his acting on an order from the Engineer, he shall immediately take written exception to the order. In any case, the Contractor shall give written notice no later than 3 days after the alleged time of occurrence or before it begins the work on which the claim is based. Submission of a notice of claim as specified shall be mandatory. Such notices by the Contractor shall not, in any way, be construed as providing or proving the validity of the claim. Failure to submit such notice within the time limits specified herein shall be a conclusive waiver to such claim for damages. An oral notice or statement will not be sufficient nor will a notice or statement after the event. At the time of occurrence or prior to beginning the work, the Contractor shall furnish the Engineer an itemized list of materials, equipment and labor for which additional compensation will be claimed. Only actual cost for materials, equipment and labor will be considered. The Contractor shall afford the Engineer every facility for keeping an actual cost record of the work. The Contractor and Engineer shall compare records and bring them into agreement at the end of each day. Failure on the part of the Contractor to afford the Engineer proper facilities for keeping a record of actual costs will constitute a waiver of a claim for such extra compensation, if so judged by the District, except to the extent that it is substantiated by the Engineer’s records. The filing of such notice by the Contractor and the keeping of cost records by the Engineer shall in no way establish the validity of the claim. The District may, at its discretion, if such claim is deemed to be justified, and by mutual agreement with the Contractor, settle the claim whereupon no further disposition will be made.


GP-24

If the Contractor’s claim contains data furnished by the Contractor that cannot be verified by the District’s records, the data shall be subject to a complete audit by the District or its authorized representative if they are to be used as a basis for claim settlement. Upon completion of the Contract, the Contractor may, within 60 days from the time the final estimate is paid, submit to the District a written claim, an original and three legible copies, for the amount he deems he is entitled to under the Contract. For the purpose of this section, the final estimate date shall be that date set forth in a letter from the Engineer to the Contractor at the time the final estimate is submitted to the District for vouchering. The claim shall set forth the facts upon which the claim is based. The Contractor shall include all pertinent data and correspondence that may substantiate the claim. Only actual cost for materials, labor and equipment will be considered. Within 90 days from the receipt of the claim, the District will make an investigation and notify the Contractor by registered mail of its decision. However, by mutual agreement, the District and the Contractor may extend the 90-day period for another 30 days. If the Contractor is dissatisfied with the decision, he shall notify the Executive Director in writing within 30 days from receipt of the District’s decision, that he desires to appear, whether in person or through counsel, and present additional facts and arguments in support of the claim. The Executive Director will schedule and meet with the Contractor within 30 days after receiving the request. However, the Executive Director and the Contractor, by mutual agreement, may schedule the meeting to be held after 30 days but before the 60th day from the receipt of the Contractor’s written request. Within 45 days from the date of the meeting, the Executive Director will investigate the claim, including the additional facts presented, and notify the Contractor in writing of his decision. However, the Executive Director and the Contractor, by mutual agreement, may extend the 45-day period for another 30 days. If the Executive Director deems that all or any portion of a claim is valid, he shall have the authority to negotiate a settlement with the Contractor subject to the provisions of Section 2.1-127 of the Code of Virginia 1950 as amended. Any monies that become payable as the result of claim settlement after payment of the final estimate will not be subject to payment of interest unless such payment is specified as a condition of the claim settlement.

SECTION 106 - CONTROL OF MATERIAL AND EQUIPMENT Sec. 106.01 - Source of Supply and Quality Requirements The materials and equipment used throughout the work shall conform to the quality requirements of the Contract. Except as otherwise specified, all materials, equipment, and components shall be new. At least ten days prior to start of work, the Contractor shall file a written statement with the District listing the origin, composition and manufacture of all materials and equipment proposed for use in the work. The Contractor’s statement shall identify all items or component materials. When optional materials and equipment are included in the Contract, the Contractor shall advise the Engineer in writing of the specific materials and equipment selected and thereafter shall use


GP-25

such materials and equipment throughout the Project, unless otherwise authorized in writing by the Engineer. Before approval of any optional material and equipment, the Contractor shall submit details, catalog cuts, or other data as required in Section 105.02. Equipment and material guaranties or warranties that are normally given by a manufacturer or supplier, or are otherwise required in the Contract, shall be obtained by the Contractor and assigned to the District in writing before termination of the Contractor’s responsibilities as specified in Section 108.13. The Contractor shall also provide an in-service operation guaranty for at least 12 months, beginning on the date of acceptance, on all mechanical and electrical equipment and related components. Sec. 106.02 - Samples, Tests, and Cited Specifications Materials may be inspected and tested by the Engineer before and during incorporation in the work. However, the inspection and testing of such material shall not relieve the Contractor of the responsibility for furnishing material that conforms to the Specifications. The Engineer may retest all materials that have been accepted at the source of supply after delivery and may reject those that do not conform to the Specifications. Stored material may be re-inspected prior to use. Work in which untested materials are used without the written permission of the Engineer may be considered unacceptable. Unless reference is made to a specific dated specification, references in these Specifications to AASHTO, ASTM, VTM, and other standard test methods and materials requirements shall refer to either the test specifications that have been formally adopted or the latest “interim” or “tentative” specifications that have been published by the appropriate committee of such organizations as of the date of the Notice of Advertisement. Unless otherwise indicated, tests for compliance with specification requirements will be made by and at the District’s expense except that the cost of retests, exclusive of the first retest, shall be borne by the Contractor. Samples shall be furnished by the Contractor at his expense, and those that are not tested by the Contractor will be tested by a representative of the District. In lieu of testing, the Engineer may approve the use of materials based upon the receipt of a certification furnished by the Contractor from the manufacturer. However, furnishing the certificate shall not relieve the Contractor of the responsibility for furnishing materials that conform to the Specifications. The Contractor shall retain and maintain copies of all written test reports and results (including written test reports and results relating to failed and/or nonconforming tests), measurements and samples for a period of at least three years following final acceptance of the Project. Upon the District’s request, the Contractor will provide the District with copies of any of these documents or access thereto, and will not dispose of them without first offering them to the District at no cost. Notwithstanding the District’s receipt of any such test reports, measurements or samples, the District is under no obligation to review them or maintain them if they have been provided to the District. The receipt by the District of such test results, measurements or samples will not in any way modify in any adverse manner the District’s rights or remedies, or the Contractor’s obligations with respect to the work or the Project.

Sec. 106.03 - Plant Inspection The Engineer may inspect materials at the source. If plant inspection is undertaken the following conditions shall be met: a. The Engineer shall have the cooperation and assistance of the Contractor and producer of

the materials. b. The Engineer shall have full access to all parts of the plant that concern the manufacture

or production of the materials being furnished. c. Adequate safety measures shall be provided and maintained. Sec. 106.04 – Storing Materials Materials shall be stored in a manner so as to ensure the preservation of their quality and fitness for the work. When considered necessary by the Engineer, materials shall be stored in weatherproof buildings on wooden platforms or other hard, clean surfaces that will keep the material off the ground. Materials shall be covered when directed by the Engineer. Stored material shall be located so as to facilitate its prompt inspection. Approved portions of the right of way may be used for storage of material and equipment and for plant operations. However, equipment and materials shall not be stored within the clear zone of the travel lanes open to traffic. Additional required storage space shall be provided by the Contractor at his expense. Private property shall not be used for storage purposes without the written permission of the owner or lessee. Copies of the written permission shall be furnished to the Engineer. Upon completion of the use of the property, the Contractor shall furnish the Engineer a release signed by the property owner indicating that the property has been satisfactorily restored. Sec. 106.05 - Unacceptable Materials Materials not conforming to the requirements of the Specifications shall be considered as unacceptable and all such materials, whether in place or not, will be rejected and shall be removed from the Project, unless otherwise approved by the Engineer. In the event it is not practical for the Contractor to remove rejected material from the Project immediately, the Engineer will mark such material for identification. Rejected material, whose defects have been corrected, shall not be used until approval has been given by the Engineer.

SECTION 107 - LEGAL RELATIONS AND RESPONSIBILITY TO THE PUBLIC Sec. 107.01 - Laws To Be Observed The Contractor shall keep fully informed of all Federal, State, and local laws, by-laws, ordinances, orders, decrees and regulations of the governing bodies, courts and agencies having any jurisdiction or authority that affects those engaged or employed on the work, the conduct of

In accordance with Title 2.2, Subtitle II, Part B, Chapter 43, Article 4 of the Code of Virginia (Virginia Public Procurement Act), the Contractor shall make payment to all Subcontractors, as defined in the Code, within 7 days after receipt of payment from the District; or, shall notify the District and Subcontractor in writing of the intention to withhold all or part of the amount due along with the reason for nonpayment. In the event payment is not made as noted, the Contractor shall pay interest at the rate of one percent per month, unless otherwise provided in the Contract, to the Subcontractor on all amounts that remain unpaid after seven days except for the amounts withheld as provided herein before. These same requirements shall be included in each subcontract and shall be applicable to each lower-tier Subcontractor. Sec. 107.02 - Sanitary Provisions The Contractor shall provide and maintain in a neat, sanitary condition such accommodations for the use of his employees as may be necessary to comply with the requirements of the State and local Boards of Health, or other bodies or tribunals having jurisdiction. Sec. 107.03 – Patented Devices, Materials, and Processes If the Contractor employs any design, device, material, or process covered by a patent or copyright, he shall provide for its use by obtaining a legal agreement with the patentee or owner. The Contractor and the surety shall indemnify and save harmless the District, any affected third party, or political subdivision from claims for infringement because of such use. The Contractor shall indemnify the District for costs, expenses, or damages resulting from infringement during prosecution or after completion of the work. Sec. 107.04 - Public Convenience and Safety The Contractor shall conduct the work to ensure the least possible obstruction to traffic. The Contractor shall provide for the safety and convenience of the traveling public using the


GP-28

Chesapeake Bay Bridge - Tunnel and the protection of persons and property as specified in Section 104.04. Sec. 107.05 – Construction Over or Adjacent to Navigable Waters The Contractor shall conduct the work on navigable waters so as to ensure the least possible obstruction to navigation and that the existing navigable depths will not be impaired except as may be allowed by a permit issued by the U.S. Coast Guard. The Contractor shall also provide and maintain temporary navigation lights and signals required by U.S. Coast Guard regulations for the protection of navigation. When the Engineer determines that the work has reached a point where such action may be taken, the channel(s) through the structure shall be promptly cleared of falsework, piling, or other obstructions placed therein or caused by the construction of the structure to the satisfaction of the Coast Guard. Sec. 107.06 – Barricades and Warning Signs The Contractor shall take all necessary precautions for the protection of the work and the safety of the public as described herein and in Sections 104.04 and 107.04 and also in Section 512 of the 2016 Road and Bridge Specifications. Barricades and warning devices shall be illuminated where required during darkness and low visibility. The Contractor shall erect warning devices in advance of a location on the Project where operations or obstructions may interfere with the use of the road by traffic and at all intermediate points where the new work crosses or coincides with an existing roadway. The Contractor shall maintain sign faces and reflective surfaces of warning devices in a clean and visible condition. Barricades, warning signs, lights, temporary signals, and other protective devices shall conform to the requirements of Section 512 of the 2016 Road and Bridge Specifications. Sec. 107.07 - Contractor's Responsibility for Work Until final acceptance of the work by the Engineer, in accordance with the provisions of Section 105.09, the Contractor shall have charge and care thereof and shall take every precaution against injury or damage to any part thereof by action of the elements or from any other cause. The Contractor shall rebuild, repair, restore, and make good all damages to any portion of the work occasioned by any of the foregoing causes before final acceptance and shall bear the expense thereof. The District may, in its discretion, reimburse the Contractor for repair of damage to work attributable to unforeseeable causes beyond the control of and without the fault or negligence of the Contractor. In case of suspension of work from any cause, the Contractor shall be responsible for the Project and shall take such precautions as may be necessary to prevent damage to the work. During such period of suspension of work, the Contractor shall properly and continuously maintain in an acceptable growing condition all living material in newly established planting, seedings, and soddings furnished under the Contract, and shall take adequate precautions to protect new tree growth and other important vegetation growth against injury.


GP-29

Sec. 107.08 - Environmental Considerations The Contractor shall at all times conduct the work in such a manner to conform with the requirements under the Federal Water Pollution Control Act, the Clean Air Act, and any other regulatory agencies having jurisdiction. Pollutants such as chemicals, fuels, lubricants, bitumens, raw sewage, paint or other harmful waste, or any construction or waste materials may not be discharged into the Chesapeake Bay or any other waters, nor unto the Fishermans Island National wildlife areas nor unto any District property. Construction materials or waste materials from a construction or repair project may not be wasted into the waters. Sec. 107.09 – Personal Liability of Public Officials In carrying out any of the provisions of these Specifications or in exercising any power or authority granted to them by or within the scope of the Contract, there shall be no liability upon the members of the Commission, the Engineer, or their authorized representatives, either personally or as officials of the District. In all such matters, they act solely as agents and representatives of the District. Sec. 107.10 – No Waiver of Legal Rights The District shall not be precluded or estopped by any measurement, estimate, or certificate made either before or after final acceptance of the work and payment therefore from showing (1) the true amount and character of the work performed and materials furnished by the Contractor, (2) that any such measurement, estimate, or certificate is untrue or incorrectly made, or (3) that the work or materials do not conform with the provisions of the Contract. The District shall not be precluded or estopped, notwithstanding any such measurement, estimate, or certificate, and payment in accordance therewith, from recovering from the Contractor or his surety, or both, such damage as it may sustain by reason of his failure to comply with the terms of the Contract. Neither the acceptance by the District or any representative of the District nor any payment for or acceptance of the whole or any part of the work, nor any extension of time, nor any possession taken by the District shall operate as a waiver of any portion of the Contract or of any power herein reserved or of any right to damages. A waiver of any breach of the Contract shall not be held to be a waiver of any other or subsequent breach. Sec. 107.11 - Certificates of Insurance The Contractor will provide the District Certificates of Insurance providing the following:

a. Certification of insurance for a general liability policy, including products liability on an occurrence basis:

Combined Single Limit $1,000,000

c. Certification of Insurance for an automobile liability policy for vehicles used by

the Contractor in connection with the said Contract:

Combined Single Limit $1,000,000 General Aggregate Limit $2,000,000

SECTION 108 - PROSECUTION AND PROGRESS Sec. 108.01 – Subcontracting No portion of the Contract shall be subcontracted or otherwise disposed of without the written consent of the Engineer. The Contractor shall perform, with his own organization, work amounting to not less than 50% of the total Contract cost, except that any items designated in the Contract as “Specialty Items” may be performed by subcontract and the cost of any “Specialty Items” so performed may be deducted from the total Contract cost before computing the amount of work required to be performed by the Contractor with his own organization. The Contractor shall submit to the Engineer for approval, no later than 15 days after receiving notice of Award of the Contract, his complete list of all proposed Subcontractors, consultants, manufacturers and suppliers. Unless otherwise specified, the Contractor will not be permitted to sublet any part of the Contract Work to a contractor who is not pre-qualified with the District, in accordance with Section 102.01. Changes shall not be made without prior notification and approval of the Engineer. Consent to subcontract or otherwise dispose of any portion of the Contract Work shall not relieve the Contractor of any responsibility for the fulfillment of the entire Contract. Sec. 108.02 - Notice to Proceed The Engineer will issue the "Notice to Proceed" within 30 days after the execution of the Contract by the District. Contract Time will start on the date specified in the "Notice to Proceed," and work shall not begin prior to this date. In no case shall work begin before the Contract is executed by the District. The Contractor shall notify the Engineer in writing at least 3 days prior to the date on which he intends to begin work. Sec. 108.03 - Prosecution of Work The Contractor shall begin work within 10 days of the date specified in the Notice to Proceed. Work shall be conducted in such a manner and with sufficient materials, equipment, tools, and labor as are necessary to ensure its completion in accordance with the Plans and these Specifications within the time limit specified in the Contract and these Specifications. Once the Contractor has begun work, it shall be prosecuted continuously and to the fullest extent possible


GP-31

except for interruptions caused by weather or delays authorized or ordered by the Engineer. If approval is given to discontinue the work temporarily, the Contractor shall notify the Engineer at least 24 hours in advance of resuming operations. Sec. 108.04 – Limitation of Operations The Contractor shall conduct the work in a manner and sequence that will ensure its expeditious completion with the least interference to traffic and shall have due regard for the location of detours and provisions for handling traffic. The Contractor shall not open any work to the prejudice or detriment of work already started. The Engineer may require the Contractor to finish a section of work before work is started on any other section. Sec. 108.05 - Progress Schedule The Contractor shall submit a progress schedule satisfactory to the Engineer prior to start of work, which shows the proposed order of work and indicates the time required for the completion of the items of work in the Contract. The schedule will be used as basis for establishing major construction operations, and as a check on the progress of the work. The progress schedule shall be duly executed by the Contractor after it has been accepted by the District. If conditions change that would require a change in the Contractor’s operations, or at the discretion of the District, the Contractor shall submit a revised progress schedule that has been mutually agreed upon. Also at the discretion of the District, as the Project may dictate, the Contractor may be required to submit monthly interim progress reports. The Contractor shall keep the District informed of planned or contemplated operations on a continuing basis. The Engineer shall be advised at least 24 hours in advance of any changes in planned operations or critical stages in the progress schedule. The review and acceptance by the District of the Contractor’s progress schedule shall in no way relieve the Contractor of his responsibility to complete the work within the Contract Time limit. Delays in work resulting from the Contractor’s failure to provide the progress schedule will not be considered just cause for extension of the Contract Time or for additional compensation. Sec. 108.06 - Character of Workers, Methods and Equipment For security reasons, all Contractor employees must carry positive photo identification, such as a Drivers License or Green Card and upon request by any District Official, shall present such identification. Workers shall have sufficient skill and experience to perform properly the work assigned to them. Workers engaged in special or skilled work shall have sufficient experience in such work and in operation of the equipment required to perform it properly and satisfactorily. Any person employed by the Contractor or by any Subcontractor who, in the opinion of the Engineer, does not perform his work in a proper and skillful manner or is intemperate or disorderly shall, at the written request of the Engineer, be removed forthwith by the Contractor


GP-32

or Subcontractor employing such person, and shall not be employed again on any portion of the work without the approval of the Engineer. If the Contractor fails to remove the person or fails to furnish suitable and sufficient personnel for proper prosecution of work, the Engineer may withhold all payments which are or may become due the Contractor and may suspend the work until the Contractor has complied with such request or orders. Equipment shall be of sufficient size and in such mechanical condition as to meet the requirements of the work and to produce a satisfactory quality of work. Equipment used on any portion of the Project shall be such that no damage to the property of the District will result. The Engineer may order the removal and require replacement of any unsatisfactory equipment. When the methods and equipment to be used by the Contractor in accomplishing the work are not prescribed in the Contract, the Contractor is free to use methods or equipment that he demonstrates to the satisfaction of the Engineer will accomplish the work in conformity with the requirements of the Contract Documents. When the Contract Documents specify that work be performed by use of particular methods and equipment, such methods and equipment shall be used unless others are authorized by the Engineer. If the Contractor desires to use a method or type of equipment other than those specified in the Contract Documents, he may request permission from the Engineer to do so. The request shall be in writing and shall include a full description of methods and equipment proposed to be used and an explanation of the reasons for desiring to make the change. If approval is given, it will be on the condition that the Contractor will be fully responsible for producing work in conformity with Contract Documents. If, after trial use of the substituted methods or equipment, the Engineer determines that the work produced does not conform to the Contract Documents, the Contractor shall discontinue the use of the substitute method or equipment and shall complete the remaining construction with the specified methods and equipment. The Contractor shall remove any deficient work and replace it with work of specified quality or take such other corrective action as the Engineer may direct. No change will be made in basis of payment for the construction items involved nor the Contract schedule time as the result of authorizing a change in methods or equipment under these provisions. Sec. 108.07 - Determination and Extension of Contract Time Contract Time will be determined by the District and specified in the Contract in Calendar Days, or as a fixed date. No request for an extension of time will be considered that is based on any claim that the Contract period, as originally established, was inadequate. The Contract Time allowed in the Contract, as awarded, is based on the original quantities shown on the Bid. If satisfactory fulfillment of the Contract, with extensions and increases, authorized under Sections 104.02 and 104.03 requires the performance of work in greater quantities than those set forth in the Bid, the Contract Time allowed for performance may be increased using one of the following methods selected at the discretion of the District:

1. The extra time allowances as agreed upon and set forth in the extra work order that covers the additional work.


GP-33

2. The same ratio that the total cost of work actually performed shall bear to the total cost shown in the Bid schedule.

During the prosecution of the work, the Contractor shall identify the causes for any delays experienced due to conditions which he deems to be beyond his control, and shall identify the particular construction operations affected, as well as the significant dates which encompass the periods of delay. The timely submission to the Engineer of such information is essential for the District to make an adequate evaluation of any subsequent claim received from the Contractor for an extension of the Contract Time. If the Contractor has not completed the work within the Contract Time limit or as extended in accordance with the requirements of this Section, he may make a written claim to the Engineer for an extension of time setting forth the reasons he believes will justify granting the claim. All claims for extension of time shall be submitted not later than 60 days following the end of the Contract. If the Engineer determines that the Work was delayed because of conditions beyond the control of and without the fault of the Contractor, the Engineer may extend the time for completion as the conditions justify. The extended time shall then be in full force and effect the same as if it had been the original time for completion.

(a) Calendar Days: When the Contract Time limit is specified in Calendar Days, the time includes Sundays, holidays, and nonworking days. When the Engineer authorizes the suspension of work in whole or in part in accordance with the requirements of Section 108.08 and such suspension is not attributable to any fault or negligence on the part of the Contractor, the Contract Time limit will be adjusted. The Contract Time limit may be adjusted on a day-for-day basis when the work is wholly suspended and on a prorated basis when the work is partially suspended.

To determine the number of Calendar Days chargeable to the Contract Time limit for work performed between the effective dates of a partial suspension order, the total dollar value of the Contract will be divided by the number of days in the Contract Time limit. The result shall be the dollar value of one day’s work. The dollar value of all work actually performed during a partial suspension period will be divided by the monetary value of one day’s work. The result, in days, will be charged against the Contract Time limit. In no case will the number of days charged be greater than the total number of Calendar Days between the effective dates of a partial suspension order. In determining the dollar value of work actually performed during a partial suspension period, the dollar value of adjustments made for work performed prior to the issuance of a partial suspension order and the dollar value of mobilization and stockpiled materials during the period will be excluded.

(b) Fixed Date: When the Contract Time limit is specified as a fixed date, the

Contractor shall take into consideration normal conditions considered unfavorable for the prosecution of the Work, and shall place sufficient workers and equipment on the Project to complete the work in accordance with the Contract Time limit.


GP-34

The Engineer may give consideration for extension of time when a delay occurs due to unforeseen causes beyond the control of and without the fault or negligence of the Contractor. However, consideration will not be given to extensions of time attributable to weather conditions or conditions resulting from weather. If there is a delay in the progress of the Work due to unforeseen causes described hereinbefore, and the delay extends the Contract Time limit into the period between November 30 of one year and April 1 of the following year and working conditions during such period are unsuitable for the completion of the Work, then consideration may be given to granting an extension of time that will encompass a suitable period during which such work can be expeditiously and acceptably performed.

When the Engineer determines that an extension of Contract Time will be made in accordance with the requirements of this Section, the daily dollar value to be used in computing time extensions resulting from monetary increases will be based on the number of days resulting from deducting 45 days from the number of days between the inclusive dates of the receipt of Bids and the fixed completion date.

At no time will the Contractor be entitled to any increased costs incurred by any such delays. Sec. 108.08 - Suspension of Work The District may suspend the Work wholly or in part by written order for such period deemed necessary due to unsuitable weather; to any condition which the District considers unfavorable for the suitable prosecution of the Work; failure of the Contractor to correct conditions deemed unsafe for workers or the general public; or failure of the Contractor to carry out the provisions of the Contract. Extension of the Contract Time which is a result of suspension orders will be determined in accordance with the requirements of Section 108.07. Suspensions of work due to the fault or negligence of the Contractor will not be just cause for an extension of Contract Time. If the performance of all or any portion of the Work is suspended or delayed by the Engineer in writing for an unreasonable period of time (not originally anticipated, customary, or inherent to the construction industry) and the Contractor believes that additional compensation and/or Contract Time is due as a result of such suspension or delay, the Contractor shall submit to the Engineer in writing a request for adjustment within 7 Calendar Days of receipt of the notice to resume work. The request shall set forth the reasons and support for such adjustment. Upon receipt, the District will evaluate the Contractor’s request. If the District agrees that the cost and/or time required for the performance of the Contract Work has increased as a result of such suspension and the suspension was caused by conditions beyond the control of and not the fault of the Contractor, its suppliers, or Subcontractors at any approved tier, and not caused by weather, the Engineer will make an adjustment (excluding profit) and modify the Contract in writing accordingly. The District will notify the Contractor of its determination whether or not an adjustment of the Contract is warranted.


GP-35

No adjustment of the Contract will be allowed unless the Contractor has submitted the request for adjustment within the time prescribed. No Contract adjustment will be allowed under this clause to the extent that the performance would have been suspended or delayed by any other cause, or for which an adjustment is provided for or excluded under any other term or condition of this Contract. Sec. 108.09 - Failure to Complete on Time Time is an essential element of the Contract, and it is important that the work be completed within the time specified. The cost of the District for the administration of the Contract, including engineers, inspection, traffic control, and supervision, will increase as the time required to complete the work is increased. For each Calendar Day that any work remains uncompleted, after the Contract Time specified for completion of the work, the District will assess liquidated damages against the Contractor. Liquidated damages, assessed in accordance with Section 108.10, at the rate applicable to the Contract for each day of additional time consumed, subject to such adjustments as provided in Section 108.07, will be deducted from any monies due the Contractor, not as a penalty, but as liquidated damages. Sec. 108.10 – Liquidated Damages The following Schedule of Liquidated Damages, representing the cost of administration, engineering, supervision, inspection and other expenses, will be charged against the Contractor for each Calendar Day beyond the Contract Time in which the Contract remains in an incomplete state:

Schedule of Liquidated Damages

Original Contract Amount in Dollars Daily Charge in Dollars

Plus – 100,000 175 100,000 – 500,000 350 500,000 – 2,000,000 600 2,000,000 – 8,000,000 1000 8,000,000 – 15,000,000 1100 15,000,000 – Plus 1400 Sec. 108.11 - Default of Contract The Contractor may be declared in default if he: a. Fails to begin the work under the Contract within ten (10) days of the date stated in the

Notice of Proceed; or


GP-36

b. Fails to perform the work with sufficient workmen and equipment, or with sufficient materials to assure prompt completion of said work; or

c. Performs the work unsuitably or neglects or refuses to remove materials, or to perform

anew such work as may be rejected as unacceptable and unsuitable; or d. Discontinues the prosecution of the work; or e. Fails to resume work, which has been discontinued, within fifteen (15) days after notice

to do so; or f. Becomes insolvent, is declared bankrupt, or commits any act of bankruptcy or

insolvency; or g. Allows any final judgment to stand against him unsatisfied for a period of ten days; or h. Makes an assignment for the benefit of creditors; or

i. Fails to maintain insurance conforming to the requirements of the Contract; or j. For any other cause, whatsoever, fails to carry on the work or contractual obligations in

an acceptable manner. In the event any of the above conditions exist, the Engineer will give notice in writing to the Contractor and his surety of the delay, neglect, or default. If the Contractor or his surety, within a period of ten days after such notice, has not taken such measures that will, in the judgment of the Engineer, ensure satisfactory progress of the work or give assurances satisfactory to the Engineer that the provisions of the Contract will be fully carried out and instructions complied with, the District may then, or at any time thereafter, take the prosecution of the work out of the hands of the Contractor, declaring him in default thereon and, without violating the Contract, call upon the Contractor’s surety for the satisfactory and expeditious completion of all work thereunder, or may otherwise terminate the Contract. In the event the Contractor is declared in default, all subsequent payments will be made to the surety, and further negotiations will be made with the surety. If the Contractor's surety fails or refuses to proceed with the work and make satisfactory progress thereon, in accordance with the instructions of the District, the District will appropriate and use any or all materials and equipment on the Project site as are suitable and acceptable, and will enter into an agreement with others for the completion of the work in accordance with the terms and conditions of the Contract, or he will use such other methods as will, in his opinion, be necessary and required for the completion of the Contract in an acceptable manner. All costs and charges incurred by the District, including the cost of completing the work under the Contract, will be deducted from any monies due, or which will become due the Contractor and his surety. If the expense so incurred by the District is less than the sum which would have


GP-37

been payable under the Contract if it had been completed by the Contractor, the Contractor and his surety will be entitled to receive the difference. Should such expense exceed the sum which would have been payable under the Contract, the Contractor and his surety shall be liable for and shall pay the District the amount of such excess. Sec. 108.12 - Termination of Contract (a) Conditions for Termination: The District may terminate the Contract or any portion

thereof because of any of the following conditions:

1. default 2. national emergency 3. action by the District, U.S. government, or court order 4. conditions beyond the control of the District

(b) Provisions of Termination: Termination will be in accordance with the following:

1. Disturbed areas shall be promptly placed in an acceptable condition as directed by the Engineer. Payment for such work will be made at the Contract unit prices or, in the absence of Contract unit prices, in accordance with the requirements of Section 104.03, or at the option of the Engineer, in accordance with the requirements of Section 109.03.

2. Payment will be made for the actual number of units or items of work completed at the Contract unit price, or as mutually agreed, for items of work partially completed. No claim for loss of anticipated profits will be considered, and the provisions of Section 104.02 will not apply.

3. Reimbursement for organizing the work when not specified in the Contract and moving equipment to and from the job will be considered where the volume of work completed is too small to compensate the Contractor for these expenses under the Contract unit prices.

4. At the option of the Engineer, materials the Contractor obtains for the work that have been inspected, tested, and accepted by the Engineer and that have not been incorporated in the work may be purchased from the Contractor at actual costs as shown by receipted bills and actual cost records at such points of delivery as may be designated by the Engineer.

5. The termination of the Contract or a portion thereof shall not relieve the Contractor of his responsibilities for the completed work, nor shall it relieve his surety of its obligation for and concerning any just claims arising out of the work performed.

Sec. 108.13 - Termination of Contractor's Responsibility The Contract will be considered complete when all work has been finished, the final inspection made by the Engineer, assignment in writing of all guarantees and warranties as specified in Sec. 106.01, and the Project accepted by the District in accordance with Sec. 105.09. The Contractor will be notified in writing of the final acceptance and his responsibility shall then cease, except as set forth in his bond.


GP-38

SECTION 109 - MEASUREMENT AND PAYMENT Sec. 109.01 - Scope of Payment Payments to the Contractor will be made for the quantities of Contract Items, measured as specified in the Technical Specifications, and performed in accordance with the Contract Documents. If, upon completion of the work, these quantities show either an increase or decrease from the quantities shown in the Contract, the Contract unit prices shall still prevail, unless they have been modified by work orders. Quantities appearing in the Contract Documents are estimated quantities for the basic design shown on the Plans. With the approval of the District, the Contractor may elect to furnish design(s) other than shown on the Plans which may involve changes in quantities or the use of different materials. However, payment will be made for plan quantities only and in the units of measure shown for the basic design, unless the dimensions for the basic design would have had to be changed by authorized modification to conform to field conditions encountered. In this event, modified plan quantities will be used for pay quantities at Contract unit prices for the items listed in the Contract Documents. The Contractor shall accept compensation, as provided for in the Contract, as full payment for furnishing all material, labor, tools, equipment and incidentals necessary to complete the work and performing all work contemplated under the Contract; for all loss or damage arising from the nature of the work or from the action of the elements or any other unforeseen difficulties which may be encountered during the prosecution of the work; and, until its final acceptance by the District, for all risks of every description connected with the prosecution of the work; for all expenses incurred in consequence of the suspension of the work as herein authorized; for any infringement of patent, trademark, or copyright; and for the completion of the work in accordance with the Contract. The payment of any partial payment, prior to the final acceptance of the Project as provided for in Section 105.09, shall in no way affect the obligation of the Contractor to repair or renew any defective parts of the construction or to be responsible for all damages attributable to such defects. Sec. 109.02 - Compensation for Altered Quantities When the accepted quantities of work vary from the estimated quantities set forth in the Contract, but such variance is within the percentage limits set forth in Section 104.02 whether or not there have been any changes in Plans, the Contractor shall accept as payment in full, so far as Contract Items are concerned, payment at the original Contract unit prices for the accepted quantities of work performed.

GP-39

Alteration of Plans or of character of work involving extra work orders as provided in Section 104.02 will be paid for at the prices for such items set forth therein. If prices cannot be agreed upon, the Contractor shall proceed with the performance of the work on a force account basis in accordance with the provisions of Section 109.03. Sec. 109.03 - Extra and Force Account Work Extra work performed in accordance with the requirements and provisions of Section 104.03 will be paid for at the agreed-upon unit prices or lump sum as specified in the extra work order or, in lieu of such agreement, the District may then require the Contractor to do such work on a force account basis with compensation in accordance with the following.

a. Labor: The Contractor will receive the rate of wage (or scale) as set forth in his most recent payroll, unless otherwise approved, for each classification of laborers, foremen, and/or superintendent(s) who are in direct charge of the specific operation. The time allowed for payment will be the number of hours that such workers are actually engaged in the work. In the event overtime work is authorized, payment will be at the normal overtime rate set forth in the Contractor's most recent payroll. In the event the class of labor needed has not been employed on the Project, mutually agreed upon rates will be established. However, the rates shall be not less than those predetermined for the Project, if applicable. An amount equal to 45 percent of the approved force account payroll will be included in the payment for labor to cover administrative cost, profit, and benefits and/or deductions normally paid by the Contractor.

b. Insurance and Tax: The Contractor will receive an amount equal to 25 percent of

the approved force account payroll (exclusive of additives for administrative cost) as full compensation for property damage and liability, workmen's compensation insurance premiums, unemployment insurance contributions and social security taxes of force account work.

c. Materials: The Contractor will receive the actual cost of materials accepted by the

Engineer, delivered and used for the work, including taxes, transportation and handling charges paid by the Contractor (exclusive of labor and equipment rentals as herein set forth), to which 15 percent of the cost will be added for administration and profit. The Contractor shall make every reasonable effort to take advantage of trade discounts offered by material suppliers, and any discount received shall accrue to the District.

d. Equipment: The Contractor shall provide the Engineer a listing of all equipment to

be used in the work. For each piece of equipment, the list shall include the serial number; date of manufacture; location from which equipment will be transported; and, for equipment to be rented, the rental rate and name of company from which equipment is rented. The Contractor will be paid hourly rental rates for pieces of machinery, equipment, and those attachments necessary for prosecution of the work, which are approved for use by the Engineer. Hourly rental rates paid for


GP-40

equipment in use will not exceed 1/176 of the monthly rates of the schedule shown in the Rental Rate Blue Book and modified in accordance with the Blue Book Rate Adjustment Tables which are current at the time the force account is authorized. Adjustment factors or rate modifications indicated on area maps in the Blue Book will not be considered when determining acceptable rates. Hourly rental rates for equipment held-in-ready will be at 50 percent of the rate paid for equipment in use.

Payment will be made for the total hours equipment is in use. When equipment is in use less than 40 hours for any given week, and is held-in-ready, payment for held-in-ready time will be allowed for up to 40 hours, less hours in use. Payment will not be made for time equipment is on the Project in excess of 24 hours prior to its actual use in the force account work. An amount equal to the Blue Book estimated operating cost per hour will be paid for all hours equipment is in use. This operating cost shall be full compensation for fuel, lubricants, repairs, servicing (greasing, fueling, and oiling), small tools and other incidentals. No compensation will be paid for use of machinery or equipment not authorized by the Engineer. The rates for equipment not listed in the Blue Book schedule shall not exceed the hourly rate being paid for such equipment by the Contractor at the time of the force account authorization. In the absence of such rates, prevailing rates being paid in the area where the work is contemplated shall be used. If the Contractor does not possess or have readily available equipment necessary for performing the force account work and such equipment is rented from a source other than a company which is an affiliate of the Contractor, payment will be based on actual invoice rates, to which 15 percent of invoice cost will be added for administrative cost and profit. If the invoice rate does not include the furnishing of fuel, lubricants, repairs, and servicing, the invoice rate will be converted to an hourly rate and an amount equal to the Blue Book estimated operating cost per hour will be added for each hour the equipment is in use.

e. Miscellaneous: No additional allowance will be made for attachments which are

common accessories for equipment as defined in the Blue Book, general superintendents, office workers (timekeepers, secretaries) the use of small tools, or other costs for which no specific allowance is herein provided.

f. Compensation: The compensation set forth in this section shall be accepted by the

Contractor as payment in full for extra work performed on a force account basis. At the end of each day, the Contractor’s representative and the Inspector shall compare and reconcile records of the cost of work done as ordered on a force account basis.

If all or a portion of the force account work is performed by an approved Subcontractor, the Contractor will be paid 10 percent of the subcontract net force account costs, before additives are applied, to cover his profit and administrative cost. The amount resulting from such 10 percent additive will not be subject to any further additives. The itemized statements of costs as required by paragraph (g)


GP-41

herein shall be submitted in a form which separates the subcontract portions of the force account labor, materials and equipment from the other force account costs.

g. Statements: No payments will be made for work performed on a force account basis

until the Contractor has furnished the Engineer with duplicate itemized statements of the cost of such force account work detailed as follows:

1. Payroll indicating name, classification, date, daily hours, total hours, rate and

extension of each laborer and foreman and/or superintendent.

2. Designation, dates, daily hours, total hours, rental rate and extension for each unit of equipment.

3. Quantities of materials, prices and extensions. 4. Transportation of materials.

Statements shall be accompanied and supported by invoices for all materials used and transportation charges. However, if materials used on the force account work are not specifically purchased for such work but taken from the Contractor's stock, then in lieu of the invoices, the Contractor shall furnish an affidavit certifying that such materials were taken from his stock, that the quantity claimed was actually used and that the price, transportation and handling claimed represent the actual cost to the Contractor. Sec. 109.04 - Eliminated Items Should any item(s) in the Contract be determined unnecessary for the proper completion of the work contracted, the District may, upon written notice to the Contractor, eliminate such item(s) from the Contract. Payment will not be made for such item(s) so eliminated, except that the Contractor will be compensated for the actual cost of any work performed for the installation of such item(s) and the net cost of materials purchased, including freight and tax costs, as evidenced by invoice. No additional compensation will be made for overhead or anticipated profits. Sec. 109.05 - Partial Payments Partial payments will be based upon a monthly progress estimate consisting of approximate quantities and value of work performed as determined by the Contractor and approved by the Engineer. When the method of measurement for a Contract item is in units of each or lump sum, the value of the work accomplished for partial payment will be determined on a pro rata basis. In order to establish a basis for partial payments for a lump sum item, the Contractor shall prepare and submit for the Engineer's approval a breakdown of all lump sum Bid items showing the values of work involved within said lump sum. The sum total of these values shall equal the lump sum price. Partial payments will be made once each month for the work performed, in accordance with the Contract requirements.


GP-42

The District will deduct an amount equivalent to 5% of the monthly progress payment and will retain such monies until final payment is made in accordance with the requirements of Section 109.06. The balance less all previous partial payments will be vouchered for payment. After 50% of the total contract value has been completed and 5% has been retained on this amount, the District will make the remaining partial payments in full provided the Contractor is maintaining a satisfactory rate of progress. Total contract value will be considered to mean the original amount of the Contract except when the Contract is increased or decreased by more than 25%, in which case the adjusted total will be considered as the total contract value. If the Contractor’s progress falls more than 10% behind the latest approved progress schedule, the progress will be considered unsatisfactory and the normal 5% retainage will be withheld for each month the Contractor is behind the progress schedule by more than 10%. When the dollar value of the Work completed has reached 90% of the total dollar value indicated on the Contractor’s latest approved progress schedule, the progress will be determined at the time of the monthly progress estimate by comparing the percentage of time used with the percentage of Work completed. When the percentage of time used exceeds the percentage of Work completed by more than 10%, the Contractor’s progress will be considered unsatisfactory and the normal 5% retainage will be withheld for each month the percentage of time used exceeds the percentage of Work completed by more than 10%. When the Engineer determines that the Contractor’s progress is considered satisfactory in accordance with these requirements, the remaining monthly progress estimate payments will be made in full. However, retainage previously withheld will not be released on subsequent monthly progress estimates. The District reserves the right to withhold the payments of any partial or final payment, or any sum or sums thereof from such a request in the event of the failure of the Contractor to promptly make payment to all persons supplying equipment, tools, materials, or for any labor used by the Contractor in the prosecution of the work provided for in the Contract, and for any other cause as determined by the Engineer. Sec. 109.06 - Final Payment When final inspection has been made by the District Representative and final acceptance has been given as provided in Section 105.09, the District will prepare the final statement of the quantity of various classes of work performed. The Contractor shall certify to the District that he has paid or made satisfactory arrangements for settling all bills for materials, labor, equipment, supplies, Subcontractors and other items entering into or used on the work and shall furnish other certificates and guaranties or warranties as are required by the District as a prerequisite to the issuance of final payment. Upon review of the final estimate by the Contractor and issuance of all required certificates, the Contractor will be paid the entire sum due after deducting all previous payments and other


GP-43

amounts to be retained or deducted under the provisions of the Contract. Final payments will become due and the final estimate vouchered for payment within 90 Calendar Days after final acceptance. Sec. 109.07 - Payment Upon District payment of the Subcontractor’s portion of the work as shown on the monthly progress estimate and the receipt of payment by the Contractor for such work, the Contractor shall make compensation in full to the Subcontractor. For the purposes of this provision, payment of the Subcontractor’s portion of the work shall mean that payment has been issued for that portion of the work that was identified on the monthly progress estimate for which the Subcontractor has performed service. If the Contractor fails to make payment to the Subcontractor within the time frame specified in Section 107.01, the Subcontractor shall contact the Engineer and the Contractor’s bonding company in writing. The Bonding Company and the District will insure payment in accordance with the requirements of Section 107.01 and Section 109.
