TO: Board of Supervisors
SUBMITTED BY: Steven E. White, Director
Department of Public Works and Planning
SUBJECT: Contract 17-23-C, SB-1 (RMRA) Asphalt Concrete Overlays
RECOMMENDED ACTION(S):
TITLE
1. Adopt plans and specifications and award Contract No. 17-23-C, SB-1 (RMRA) Asphalt Concrete Overlays to the low bidder, Cal Valley Construction, 5125 N. Gates, Suite 102, Fresno, CA 93722, in the amount of $4,626,757.30 for the base bid and all the additive bids.
2. Authorize the Director of the Department of Public Works and Planning, or designee, to execute Contract Change Orders up to $210,000 which is approximately 4.5% of the total contract construction cost, the limit allowable under California Public Contract Code, section 20142 for Contract 17-23-C.
REPORT
Approval of the first recommended action will authorize the award of a budgeted road improvement project. Approval of the second recommended action will allow the Director of the Department of Public Works and Planning, or designee, to execute change orders up to the statutory limit. This item pertains to multiple locations in Districts 1, 4, and 5.
ALTERNATIVE ACTION(S):
If the first recommended action is not approved, the project will be delayed. If the second recommended action is not approved, the Director’s, or designee’s, authority to approve Contract Change Orders will be limited to $71,267.
FISCAL IMPACT:
There is no Net County Cost associated with the recommended actions. The anticipated cost of the project, based on the low bid and including an allowance for contingencies, is $4,836,757 (contract plus change orders). The project will be paid for out of the Road Maintenance and Rehabilitation Account (RMRA) under Senate Bill (SB) 1 and sufficient appropriations are included in the Department’s Org 4510 FY 2017-18 Adopted Budget.
DISCUSSION:
The work to be done consists, in general, of furnishing and placing hot mix asphalt (HMA) concrete type A overlay on various existing roads in Fresno County. The base bid will require the placement of HMA overlay over approximately 8.39 miles of roadway. An additional 5.12 miles of County roads are included as additive bids.
The second recommended action will allow the Department’s Director, or designee, to execute change orders for the project up to the statutory limit, based on the lowest responsive bid amount. The Public Contract Code (PCC), section 20142 limits the extent to which the Director may be authorized to execute Contract Change Orders to 10% of the first $250,000, plus 5% of the contract amount in excess of $250,000, up to a maximum authorization of $210,000. However, the Board’s policy, last updated in 1991, limits the Director’s authority to the amount of 10% of the first $250,000, plus 1% of the contract amount in excess of $250,000, up to a maximum authorization of $100,000. For this project, this amounts to $25,000, plus 1% of $4,626,757.30 for a total authorization of $71,267. The Board’s authorization for the Director to approve Contract Change Orders up to this statutory limit would reduce the time required to process changes, reduce paperwork, help keep cost down, and reduce potential claims for additional cost and time due to administrative delays. The Contract Change Order authorization would not apply to, nor allow changes to, the scope of the work.
The Department received five bids for this project May 18, 2018. The low bid was $4,626,757.30, which is $1,170,849.80, or 25.31% lower than the engineer’s estimate of $5,797,607.10. This was due to a lower than anticipated cost for traffic control, cold plane AC pavement, removal of AC pavement, shoulder backing, finishing roadway, and mobilization.
