The Balboa Island Water Replacement — Phase I Project (Contract No. 7173-1)
addressed replacement of older cast iron water mains identified in the Water Master Plan
for replacement. The contract provided for the construction of new water mains, valves,
and fire hydrants for Balboa Avenue, Collins Avenue and Opal Avenue along with the
ancillary concrete pavement replacement.
The contract was completed to the satisfaction of the Public Works Department. A
summary of this contract's construction cost is as follows:
Original bid amount: $1,563,400.00
Actual Cost of Bid Items Constructed: $1,350,458.00
Total Change Orders: $ 98,869.45
Final contract cost: $1,449,327.45
The actual cost of bid items constructed was $212,942.00 less than the original bid
amount due to a reduction in the amount of street pavement replacement than originally
planned. This is the first of a three-year water replacement project for Balboa Island that
focuses on replacing old deteriorated cast iron water mains. With that in mind, staff
reduced the pavement replacement limits with the intent to come back after all water
replacement work has been completed and address the ultimate pavement work with a
larger street and alley pavement replacement project.
Three contract change orders were approved as part of the project totaling $98,869.45.
The change orders included some additional costs for night work adjacent to the Marine
Avenue area and use of rapid set concrete in order to open up alley and streets to traffic
within 24-48 hours. Additionally, during the project many of the existing water values
were found to be deteriorated and unable to provide water shut-off necessitating contract
changes for additional water valve replacements along the N. Bayfront Alley and Balboa
Avenue.
