RECOMMENDATION(S):

(1) APPROVE plans, specifications, and design for the Three Creeks Parkway Restoration Project, Brentwood area. County Project No. 7562-6D8490 (District III)


(2) DETERMINE that the bid submitted by Granite Rock Company (Granite Rock), the lowest monetary bidder, submitted the lowest responsive and responsible bid for this project

RECOMMENDATION(S): (CONT'D)

(3) AWARD the construction contract for the above project to Granite Rock in the listed amount ($2,596,907.07 Base Bid plus Bid Alternates 1, 2, 3, and 4) and the unit prices submitted in the bid, and DIRECT that Granite Rock shall present two good and sufficient surety bonds, as indicated below, and that the Chief Engineer, or designee, shall prepare the contract.

(4) ORDER that, after the contractor has signed the contract and returned it, together with the bonds as noted below and any required certificates of insurance or other required documents, and the Chief Engineer has reviewed and found them to be sufficient, the Chief Engineer, or designee, is authorized to sign the contract for this Board.

(5) ORDER that, in accordance with the project specifications and/or upon signature of the contract by the Chief Engineer, or designee, any bid bonds posted by the bidders are to be exonerated and any checks or cash submitted for security shall be returned.

(6) ORDER that, the Chief Engineer, or designee, is authorized to sign any escrow agreements prepared for this project to permit the direct payment of retentions into escrow or the substitution of securities for moneys withheld by the County to ensure performance under the contract, pursuant to Public Contract Code Section 22300.

(7) DELEGATE, pursuant to Public Contract Code Section 4114, to the Chief Engineer or designee, the Board’s functions under Public Contract Code Sections 4107 and 4110.

(8) DELEGATE, pursuant to Labor Code Section 6705, to the Chief Engineer or to any registered civil or structural engineer employed by the County the authority to accept detailed plans showing the design of shoring, bracing, sloping, or other provisions to be made for worker protection during trench excavation covered by that section.

(9) DECLARE that, should the award of the contract to Granite Rock be invalidated for any reason, the Board would not in any event have awarded the contract to any other bidder, but instead would have exercised its discretion to reject all of the bids received. Nothing in this Board Order shall prevent the Board from re-awarding the contract to another bidder in cases where the successful bidder establishes a mistake, refuses to sign the contract, or fails to furnish required bonds or insurance (see Public Contract Code Sections 5100-5107).

FISCAL IMPACT:

The construction contract and associated fees of this project will be funded by Drainage Area (DA) 130 funds. Approximately, $1,491,810 is expected to be reimbursed by American Rivers, the District’s project partner, through a funding agreement approved by the Board on January 21, 2020.

BACKGROUND:

The above project was previously approved by the Board of Supervisors, plans and specifications were filed with the Board, and bids were invited by the Chief Engineer. On January 21, 2020, the Flood Control and Water Conservation District (District) received bids from the following contractors:

BIDDER, TOTAL AMOUNT, BOND AMOUNTS (Base Bid plus Bid Alternates 1, 2, 3, and 4)

Granite Rock Company, $2,596,907.07; Payment: $2,596,907.07; Performance: $2,596,907.07

PMK Contractors LLC, $2,877,231.00

Suulutaaq, Inc., $2,928,395.90

Gordon N. Ball, Inc., $3,052,471.29

Interstate Grading & Paving Inc., $3,662,123.00

Ghilotti Bros, Inc., $3,880,000.64

Bay Cities Paving & Grading, Inc., $4,491,637.80

The bidder listed first above, Granite Rock, submitted the lowest responsive and responsible bid, which is $280,323.93 less than the next lowest bid.

The Chief Engineer recommends that the bid submitted by Granite Rock is the lowest responsive and responsible bid, and this Board concurs and so finds.

The Board of Supervisors previously adopted the Initial Study/Mitigated Negative Declaration together with Addendum No. 1 and Addendum No. 2 on November 12, 2019 in compliance with the California Environmental Quality Act (CEQA), and a Notice of Determination was filed with the County Clerk on November 13, 2019.

The general prevailing rates of wages, which shall be the minimum rates paid on this project, have been filed with the Clerk of the Board, and copies will be made available to any party upon request.

The Three Creeks Parkway Restoration Project will widen Marsh Creek to allow for the needed flood conveyance and habitat restoration. The project, a joint effort by the District and American Rivers, is funded by the District and American Rivers through several federal, State, and private entities funds.

CONSEQUENCE OF NEGATIVE ACTION:

Construction of this project would be delayed, and the project might not be built.
