At 11:00 a.m. on February 18, 2014, the City Clerk opened and read the following bids for
this project:
BIDDER TOTAL BID AMOUNT
Low General Pump Company $ 436,370.00
2 South West Pump & Drilling, Inc. $ 649,912.00
3 Best Drilling and Pump, Inc. $ 712,600.00
The total low bid amount is 25 percent below the Engineer's Estimate of $583,000.00. 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.
