est'unate, to include a complete reconstruction of the pump stations based upon a detailed review of pump station components in the field, and the fact that the City's Utility Operations Division had experienced a number of pipeline leaks around the pumping stations since 1998. The pump station re-construction project will replace all three pump stations' piping, valving, pumps, pump cans, electrical equipment, and will upgrade the existing Pacific Gas and Electric Company (PG&E) service from an old "Y' system to more reliable "Delta" system. Also designed were a new split face block building structure for each station including foundation slab, a chlorine injection room at one station, a small water tank at one station, site grading, storm drainage system, asphalt paving, utility line relocation, and new operational control system at each of the pump stations. The project was designed, advertised and put out to public bid. On November 23, 2004 six bids were received and are listed below. Bidder Name Amount Rank John Clay General Engineering Contractor $2,322,414 1 GSE Construction $2,778,900 2 Albay Construction $3,072,000 3 Aztec Consultants Inc. $3,147,000 4 Proven Management Inc. $3,171,671 5 Blocka Construction $3,548,500 6 The design engineer's probable construction cost estitnate for this project was $1.8 million. The apparent low bidder, John Clay, has since asked the City to withdraw his bid due to a mathematical error in his bid proposal. The mathematical error amounted to an additional $270,000 to their bid, bringing the bid to approx. $2.6 million. Staff has reviewed supporting documentation provided by John Clay to substantiate their claim. Under the Public Contract Code provisions, contractors can be excused from their bids in which mathematical errors occur. Staff contacted the second low bidder, GSE Construction, to contrmn their confidence in the bid amount submitted and their willingness to perform the work. GSE verbally confirmed their bid price was valid and was willing to honor their bid at $2,778,900. A reference check on past work performed by them was found to be satisfactory. However, as noted, if the City were to accept the second low bid, the bid amount would be approximately $1 million over the estimated construction cost on the project or approximately $900,000 over this project's current fund balance as further described below.
