On June 22, 1998, the City Council authorized the award of the Back Bay Drive
Roadway and Bridge Approach Repair, Contract No. 3180, to Summit Contracting of
Duarte, California. The contract provided for the repair of bridge approaches, the
construction of a depressed concrete roadway for purposes of providing a drainage
swail and other pertinent repair work needed to correct damages caused by the 1997 -
1998 El Nirio winter storms. 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: $174,990.67
Actual amount of bid items constructed: 177,948.00
Total amount of change orders: 30,268.67
Final contract cost: $208,216.67
The increase in the amount of actual bid items constructed over the original bid amount
resulted from the need for additional riprap exceeding the bid item quantities. The final
overall construction cost including change orders was 19.0% over the original bid
amount.
A total of two (2) change orders were issued to complete the project. They were as
follows:
1. A change order in the amount of $30,000.00 provided for the removal of a massive
landslide from an Irvine Company slope onto Backbay Drive near Shellmaker Island.
Funds for the $30,000.00 were deposited from The Irvine Company with the City.

date was September 28, 1998. Due to extra work, inclement weather, the December
holiday season and the non - availability of treated lumber piles, the completion date was
extended to January 11, 1999. All work was substantially completed by that date.
