2.1. Summary

West County Wastewater District (WCW) is soliciting bids from qualified contractors to provide construction services for the Secondary Sedimentation Basins 1 and 2 Short-Term Improvements Project at the Water Quality & Resource Recovery Plant (WQRRP). WCW identified the need to rehabilitate and upgrade all four secondary sedimentation basins at the WQRRP to maintain reliable operation and treatment performance and retained Black & Veatch to provide engineering design services for the improvements.

The work under this contract is limited to Secondary Sedimentation Basins (SSB) 1 and 2 and generally includes demolition, concrete repairs, coatings, mechanical improvements, site restoration, and all other work necessary to complete the improvements in accordance with the Contract Documents. West

3.14. PROPOSAL OPENING AND AWARD OF CONTRACT

Proposals will be kept unopened until the time stated for opening of proposals. At such time, the contents of the proposal will be made public. No responsibility shall attach to WCW or any of its officers, employees, or representatives for the premature opening of a proposal. All bidders or their authorized representatives are invited to be present at the proposal opening.

If award is made, it will be based on the lowest responsive, responsible bid whose base bid is the lowest.

The right is reserved, as the interest of WCW may require, to reject any or all proposals and to waive any informality in proposals received.

Within sixty (60) days after the time of opening of the bids, WCW will act either to accept a bid, to reject all bids or with the consent of the bidders and their sureties to extend the time in which WCW may act.

The acceptance of a bid will be evidenced by a Notice of Award of Contract in writing, delivered in person or by certified mail to the bidder whose bid is accepted. No other act of WCW will constitute acceptance of a bid. The Award of Contract shall obligate the bidder whose bid is accepted to furnish performance and payment bonds and evidences of insurance, and to execute the Agreement in the form set forth in the Contract Documents. The Contract will require the completion of the Work according to the Contract Documents.

The Agreement shall be executed by the successful bidder and returned, together with the Contract bonds and evidences of insurance, within the specified time period after receiving written Notice of

Award of the Contract. Time is of the essence in this regard. After execution by the owner, one copy of the Agreement shall be returned to Contractor.

The failure of any bidder to whom WCW may award the Contract, as aforesaid to sign and return to

Title: Secondary Sedimentation Basins Upgrades Project - Short-term Improvements for Basins (1) & (2)

WCW, the Contract together with the required Performance Bond, Payment Bond, and insurance certificates and endorsements the specified time period, shall entitle WCW to declare a breach of

Contract by such bidder, to award the Contract to another bidder in accordance with the provisions of the Contract Documents, and to declare a forfeiture of the bidder's proposal security accompanying its proposal.

In the event of such failure, WCW will suffer damage, the amount of which is difficult, if not impossible, to ascertain, and WCW shall therefore be entitled to retain the amount of such cashier or certified check, submitted by the bidder as proposal security, or to enforce the provisions of the Bidder's Bond in the amount thereof, as liquidated damages for such breach of Contract, as provided by applicable law.

3.15. RELIEF OF BIDDERS

Should a bidder claim a mistake was made in its bid, the bidder shall give the WCW written notice within five (5) calendar days after proposal opening of the alleged mistake, and detail in said notice the circumstances under which the mistake occurred all in accordance with Public Contract Code, Section

5103. Final determination of relief of bidders shall be made by WCW Board. Should the WCW Board accept the bidder's claim for relief, the bidder will be released from all obligations and further requirements and its proposal security will be returned as applicable.

3.16. BONDS AND INSURANCE POLICIES

The bidder to whom the contract award is made shall, at the time of execution of the Contract, furnish to WCW a Performance Bond and a Payment Bond, executed as surety by a corporation acceptable to

WCW and authorized to issue such surety bonds in the State of California. Such bonds shall be substantially in the form included with this solicitation. Such Performance Bond and Payment Bond shall be for one hundred (100) percent of the proposal total as set forth in the Schedule of Bid. The entire cost of these bonds shall be borne by the successful bidder.

If the surety on any bond furnished by the Contractor is declared bankrupt, or becomes insolvent, or its right to do business is terminated, or it ceases to meet the requirements of the above paragraph, the

Contractor shall, within five (5) calendar days thereafter, notify WCW and substitute another bond and surety, both of which must be acceptable to WCW.

3.17. NONDISCRIMINATION IN EMPLOYMENT
