This low bid amount may be attributed to the contractor's familiarity with the City's well site as they have performed work on this well in past years. The low bidder, General Pump Company, possesses the California State Contractor's License Classification "C -57" as required by the project specifications. A check of the contractor's references indicates they have satisfactorily completed similar projects for other municipalities. This contract involves rehabilitating the Dolphin Deep Water Well at 9469 Dolphin Street, Fountain Valley. Work needed to complete the contract includes: Pump and Motor Repair Wire Brush and Bailing Air - jetting Mechanical Development Chemical Development Video Surveys Test Development Pumping Installing a Well Casing Liner The City's groundwater is pumped from four existing wells in Fountain Valley, each owned and operated by the City of Newport Beach. To prevent potential failure of these wells, they need to be monitored and rehabilitated regularly. Wire brushing and air bursting of a well 256 casing is needed to remove the build -up of minerals and sediments. Pumps and motors need to be reconditioned periodically to maximize efficiency. Upon review of recent video surveys, staff noticed small holes in the Dolphin deep water well casing. In order to prevent further damages to the original well casing, a casing liner will be installed as part of this contract. Depending on the outcome of additional video surveys, steel patches may be installed to prevent sand from entering the well. Pursuant to the Contract Specifications, the Contractor will have 50 consecutive working days to complete the project. This item was placed on Current Business instead of the Consent Calendar because of the dollar amount of the appropriation. There is no known controversy associated with this item. ENVIRONMENTAL REVIEW: This project is exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15302 Class 2 (c) of the CEQA Guidelines, California Code of Regulations because it does not have the potential to have significant environmental effects as the project is the repair of existing facilities involving negligible or no expansion of existing capacity.
