The work necessary to complete this contract consisted of widening the westerly side of
the existing Jamboree Road Bridge over the 73 Freeway by 24 feet to accommodate
one additional thru lane in either direction. The contract has now been completed to the
satisfaction of the Public Works Department. A summary of the contract cost is as
follows:

Actual cost of bid items constructed: $3,141,876.80
Contract change orders:
Final contract cost:
$386,345.88
$3,528,222.68
The final overall construction cost, including 11 change orders, was approximately
10.4% above the original bid amount. The major change orders were for additional cost
related to the pile that the bridge abutments and columns were constructed on,
additional cost for groundwater encountered on the tie -backs on the southerly abutment
and modifications to the columns to allow for the bridge seismic retrofitting of the
existing structure.
The notice to proceed allowed for 280 consecutive working days based on the scope of
the work. With approved time extensions, the project was substantially completed
