AGENDA REPORT
FOR
RESOLUTION APPROVING THE PROJECT BUDGET AND AUTHORIZING AWARD
OF CONTRACT FOR THE WASHINGTON STREET BRIDGE REHABILITATION- COLUMN
REPAIR PROJECT No. C501404 TO NORTH COAST DIVERS INC.
1. EXECUTIVE SUMMARY:
On March 27, 2008, the City received three (3) bids for the Washington Street Bridge
Rehabilitation -Column Repair Project, ranging from $96,716 to $290,800. The project involves
removing unsound concrete and cleaning exposed steel bar reinforcement at thirteen bridge
columns, and encapsulating them with a marine protection system to protect the columns from
corrosion. The work is anticipated to begin in mid-June and is expected to be completed in
August.
2. BACKGROUND:
Caltrans Department of Structures periodically inspects all bridges in the State of California.
During a recent inspection, they recommended all thirteen columns of the Washington Street
Bridge be rehabilitated by encapsulating them , with a marine protection system to protect the
columns ffom corrosion. The protection system consists of a column jacket, scaled to keep water
out, that is then pressure grouted.
Department of Public Works staff, through a design consultant, prepared the plans and
specifications for this project. The Notice Inviting Bids was issued on February 21, 2008. Bids
were received and opened on March 27, 2008, as follows:
NAME OF BIDDER BID AMOUNT
North Coast Divers Inc., Petaluma, CA $96,716
Valentine Corporation, San Rafael, CA $153,360
Granite Construction Company, Healdsburg, CA $290,800
The engineer's estimate for construction is $120,000
With a bid. of $96,716; the apparent low bidder is North Coast Divers Inc. Staff verified that
North Coast Divers possesses a valid Class A California contractor's license, number 660428,
expiring on December 31, 2008, which qualifies them to perform the work.
Since the bridge columns are submerged all the time, it is very difficult to closely inspect and
gauge the, extent of"the repair. Therefore, the plans and specifications were prepared based on
staff's engineering judgment. It will be left to the contractor to propose and submit a method of
repair for review and ,acceptance, using SCUBA equipment, rather than placement of a
temporary water tight enclosure (coffer dam), which is pumped dry in order for construction to
be undertaken. Although allowing the contractor to propose the method of repair assures the

lowest .cost for construction, it does require additional staff time and increase the potential for
change orders. 'In addition, the City will need to hire an experienced diver qualified to inspect
such work. Due to "these complexities, a contingency of $48,000 is being requested to cover
unforeseen extra work and/or unknowns. While this.is not a large dollar amount considering the
type of work, as a percentage of the contract (50%), the amount is unusual.
3. ALTERNATIVES:
1. Award the contract to the low bidder.
2. Award the contract with a lesser contingency. This would require a future Council action if
additional funds are required. Obtaining approval prior to expending additional funds can
result in project delays, and potential delay claims from Contractor.
3. Take no action.
4. FINANCIAL IMPACTS:
The following is a breakdown of the estimated costs:
Construction Contract (low bid) $96,716
Engineering Design 34,000
Administration/Inspection 50,000
Const. Contingency 48,000
CIP Overhead 11,500
Estimated Total Cost $240.216
The estimated total cost, including planning, design, .construction, administration, inspection,
testing and project contingency, is $240,216. CIP Project C501404, funded by Traffic
Mitigation Impact Fees in the amount of $742,000, originally included deck treatment at
Lakeville Street Bridge, Payran Street . Bridge, Satori Drive Bridge and Washington Street
Bridge, in addition to this column repair of the Washington St. Bridge. However, due to the very
different type of work, the column repair was separated from the bridge deck treatment. The
City already received bids fovthe bridge deck treatment project on January 31St and construction
is scheduled to begin in late April. The approved project budget for that work is $238,000.
5. CONCLUSION:
Following the award, the contractor will enter into agreement with the City and submit the
required contract documents, bonds and insurance.
6. OUTCOMES OR PERFORMANCE MEASUREMENTS THAT WILL IDENTIFY SUCCESS OR
COMPLETION:
Completion of construction.
7. RECOMMENDATION:
City staff recommends City Council adopt the resolution awarding the contract to the low bidder,
North Coast.Divers Inc.
