Discussion:
On May 27, 2008, the City Council authorized the award of the Birch Street Pavement
Rehabilitation project to All American Asphalt. The contract provided for the removal
and reconstruction of deteriorated concrete sidewalks, curb and gutters, driveway
approaches, cross gutters and curb ramps. It also includes cold milling of existing
asphalt pavement, and overlaying the existing pavement section with rubberized
asphalt. 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: $609,609.00
Actual amount of bid items constructed: $497,851.89
Total amount of change orders: $3,405.00
Final contract cost: $501,256.89
The decrease in the actual amount of bid items constructed over the original bid
amount primarily resulted from a decrease in the amount of asphalt concrete needed.
The final overall construction cost including one change order was 17.8 percent below

the original bid amount. The one change order was for the removal and replacement of
traffic signal loop conduits and minor concrete work.
A summary of the project schedule is as follows:
Estimated completion date per June '07 schedule: May 19, 2008
Project award for construction: May 27, 2008
Estimated completion date at award: September 15, 2008
Actual substantial construction completion date: September 9, 2008
The project was substantially completed approximately 4 months behind schedule. The
delay was caused by Caltrans' review of funding application. Per the June '07
schedule, staff anticipated receiving authorization (to advertise contract) from Caltrans
by September 27, 2007. Authorization to proceed was not received until February 13,
2008; approximately 5 months after the anticipated date.
Environmental Review:
The project was determined to be exempt from the California Environmental Quality Act
(CEQA) pursuant to Section 15301 of the CEQA Implementation Guidelines at the time
the project was authorized by the City Council. This exemption covers the repair,
maintenance and minor alteration of existing public facilities with negligible expansion.
Funding Availability:
In addition to the primary construction contract, this project involved other project
expenses. Total project expenses are summarized as follows:
Construction $501,256.89
Material Testing — Harrington Geotechnical $3,854.00
Incidentals $583.86
