DISCUSSION:
On June 8, 1998, the City Council authorized the award of Corona del Mar Water Main
and Alley Replacements, Contract No. 3191 to Gillespie Construction, Inc. of Costa
Mesa, California. The contract provided for the replacement of 5,200 linear feet (one
mile) of water main and the reconstruction of alley improvements in Corona Del Mar
(see Exhibit "A "). In addition, a sewer force main from the Buck Gully Pump Station
was reconstructed. The contract has now been completed to the satisfaction of the
Public Works Department. A summary of the contract cost is as follows:
Original bid amount: $791,418.75
Actual amount of bid items constructed: 757,984.69
Total amount of change orders: 77,860.56
Final contract cost: $835,845.25
The decrease in the amount of actual bid items constructed over the original bid
amount resulted from the deletion of reconstructing one alley and a reduction in the
amount of concrete pavement from the bid item quantities. The final overall
construction cost including change orders was 5.6% over the original bid amount.
A total of nine change orders were issued to complete the project. A summary of the
change orders are as follows:
1. Two change orders totalling $17,825.70 provided for the removal and
replacement of forty feet of sewer line and the reconstruction of a 23 foot
deep sewer manhole.
