The bid from Stratus Construction Company was withdrawn by the contractor because of serious math
errors. The second bid came in significantly higher than the engineer's estimate, which was prepared by
the consultant engineer, Civil Hydro Tech. The consultant engineer reviewed the bid prices and
determined that clarifying the well destruction methods and type of waste inside the carbon vessels would
attract a larger pool of bidders and more competitive pricing.
This project is under the order of the State Water Resource Control Board (Board). Board staff expected the
project to be completed by early 2020. ln order to expedite the contract work, Staff recommends rejecting all
bids, approving specifications, authorizing re-advertisement for bids, authorizing City Manager to award

Decommissioning the SVE system would reduce the operation and maintenance costs by an estimated $150,000 annually. Justification/factor driving projectThis project will provide funding for the decommissioning of the City owned and contractor operated soil/vapor and groundwater extraction (SVE) system located at the Central Plume Source Area (CPSA).
