FINANCIAL STATEMENT:
DESCRIPTION: This Capital Improvement Program Maintenance Project cleaned
and sealed both sides of the concrete barrierlsoundwall, including hairline concrete cracks, located along
portions of the east side of San Ramon Road.
This project was originally bid in May of Fiscal Year 2006-2007, with the result that only one bid was
received in the amount of $120,000. Based on the opinion that this was not a good representative bid, the
City Council rejected the bid and directed Staffto re-bid the project at a later date.
The specifications for the project were revised to use an elastomeric coating to seal the wall without
having to individually repair hairline cracks in the concrete. However, in discussing the use of this
product with various contractors, indications were given that the cost of the project would be in the range

of $50,000 to $60,000 to treat one side of the wall. Since $70,000 had been budgeted for construction, the
decision was made to only bid treatment of the face of the wall.
When bids were opened for this project, the low bid came in at $28,900 from Quality Painting &
Construction. Upon Staffs verification of the validity of the bid, the City Council awarded the contract to
the low bidder. Because of the amount of the low bid, a Change Order was processed to also treat the
back of the wall.
During the course of the work, an inspection was performed of the sealing on the back of the wall.
Several locations were discovered where the concrete had spalled over some of the reinforcing bars on the
back of the wall. A Change Order was subsequently generated to repair the spalls on a time and materials
basis not to exceed $5,000. The final cost of construction is $49,396.
Quality Painting & Construction has now completed the work per the project specifications and to the
satisfaction of the Public Works Director.
Staff recommends that the City Council accept improvements under Contract No. 07-08A, San Ramon
Road Concrete Soundwall Sealing (CIP No. 94601), and authorize the release of retention after 35 days if
there are no subcontractor claims.
