This project will rehabilitate the City of Newport Beach's Tamura Shallow water well to maintain performance and restore water production. RECOMMENDATION: a) Find this project exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15302(c) Class 2, (reconstruction of existing facility involving negligible or no expansion of capacity) of the CEQA Guidelines, because this project has no potential to have a significant effect on the environment; b) Approve the project plans and specifications; c) Award Contract No 8727-2 to General Pump Company, Inc. for the total bid price of $331,678, and authorize the Mayor and City Clerk to execute the contract; and d) Establish a contingency of $33,000 (approximately 10 percent of total bid) to cover the cost of unforeseen work not included in the original contract. DISCUSSION - At 10:00 a.m. on November 30, 2021, the City Clerk opened and read the bids for this project: RX BIDDER TOTAL BID AMOUNT Low General Pump Company, Inc. $ 331,678 2nd Best Drilling and Pump, Inc. $ 471,244 RX Water Well Rehabilitation — Tamura Shallow Well (Project No. 22W05) — Award of Contract No. 8727-2 January 11, 2022 Page 2 The City of Newport Beach (City) received two bids for this project. The low bidder, General Pump Company, Inc., possesses a California State Contractor's License Classification "C-57" Water Well Drilling, as required by the project specifications. A review of references for General Pump Company, Inc. shows satisfactory completion of similar contracts for the City and other municipalities. General Pump Company successfully completed the rehabilitation of other City water wells in recent years. The low bid was 5.2 percent below the Engineer's Estimate of $350,000. The minor difference between the bid and the Engineer's Estimate was mainly attributed to lower than estimated mobilization cost. The Tamura Shallow water well is an integral part of the City's water supply system. The pumping capacity of this well has declined over the last year to the point that it can no longer operate. This well was last rehabilitated in 2016. Water wells usually require rehabilitation every five to seven years to maintain performance and restore water production. The proposed project includes removing the existing pump and motor, conducting down -well video surveys, wire brushing, chemical treatment, mechanical treatment, performing test pumping, and installing a new pump. Pursuant to the contract specifications, the contractor will have 45 consecutive working days to complete the work. Work is scheduled to start in February, after the contract is executed.
