Stephens Construction Co., Inc., of Lodi ($601,714) MEETING DATE: January 6, 2021 PREPARED BY: Public Works Director RECOMMENDED ACTION: Adopt resolution awarding contract for Central Plume PCE/TCE Groundwater and Soil Vapor Extraction System Decommissioning and Removal to A.M. Stephens Construction Co., Inc., of Lodi, in the amount of $601,714. BACKGROUND INFORMATION: Council approved the specifications and authorized advertisement for bids on August 19, 2020. This project consists of decommissioning the Soil Vapor Extraction and the groundwater extraction and treatment systems located near the alleyway that lies between Pine and Oak Streets, and Pleasant Avenue and Church Street, as shown on Exhibit A. The City received two bids on September 30, 2020. The first bid was withdrawn by the contractor because of serious math errors, The second bid came in significantly higher than the engineer's estimate, which was prepared by the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. On October 21, 2020, Council rejected all bids, approved specifications and reauthorized advertisement for bids for this project. To make up time associated with the rebidding process, this Council action also authorized the City Manager to award to the lowest responsive bidder in an amount not to exceed $600,000. The City received the following three bids for this project on December 2, 2020: Bidder Location Engineer's Estimate A.M. Stephens Const. Co., Inc. Lodi Pacific States Enviro. Const. Dublin Diede Construction Woodbridge The lowest responsive bid, provided by A.M. Stephens Construction Co., Inc., of Lodi, was $601,713.90, which was $1,713.90 over the authorized amount, therefore requiring Council approval to award.
