BACKGROUND

At the bid opening on June 15 a total of four (4) bids were received.  The bids were reviewed and the lowest responsive, responsible bid was received from S.J. Amoroso Construction Co., Inc. and Pacific Mechanical Corporation, a Joint Venture, in the amount of $39,272,135.00.

The 4 bids were:

1.      S.J. Amoroso / Pacific Mechanical                       $39,272,135.00

2.      Walsh Pacific                                                     $39,975,537.00

3.      Monterey Mechanical                                          $41,610,000.00

4.      Kiewit Pacific                                                     $45,575,000.00

Staff is exploring all options to reduce the cost of the plant without jeopardizing reliability, capacity or functionality and will continue to do so with the contractor should the contract be awarded. We have already seen the benefits of cost reduction engineering on this project due to he last minute re-design to allow the use of rock columns vs. piles. All of he bidders elected to bid rock columns instead of the piles and it is estimated that this change saved the City approximately $700,000.00

The Fiscal Year (FY) 99/00 budget contains funds for the Wastewater Treatment Plant Expansion Project, CIP Project No. 592-5911, in the amount of $43,606,500.  The majority is to be funded from a 0% interest loan from the State Water Resources Control Board’s State Revolving Fund Loan Program (SWRCB).  The amount shown for the low bid is over the amount estimated when the loan was secured with the State; however, it is well within the loan authorization of the SWRCB staff.
