BACKGROUND
Sierra Highway is classified as a major arterial and a Congestion Management Plan (CMP) route
for the region. In 1996, the City restriped Sierra Highway to accommodate three lanes of travel in
each direction in order to serve the growing number of motorists along this roadway.
This project will replace and/or rehabilitate the existing northbound and southbound bridges on
Sierra Highway over the railroad while providing wider travel lane widths for motorists and
cyclists, and standard sidewalks for pedestrians in each direction. In consideration of the low
Caltrans Bridge Sufficiency List (BSL) rating that has been calculated for the northbound bridge,
a determination has been made to replace this structure. In contrast, a more favorable BSL rating
calculated for the southbound bridge yielded the need to rehabilitate it with a concrete product
overlay.
On January 10, 2006, the Purchasing office received one bid for the project, submitted by Griffith
Company, Inc. in the amount of $6,098,894.50. Staff recommends that the project be awarded to
Griffith Company, Inc. Griffith Company, Inc. possesses a State contractor's license and is in
good standing with the State Contractor's License Board. The bid of $6,098,894.50 was
reviewed for accuracy and conformance to the contract documents and was found to be complete.
References were checked and indicated that this contractor has performed work that met their
customers' goals.
Construction of the proposed project will relieve and improve traffic flow and promote public
safety. Improvements include the removal and replacement of the northbound structure and the
rehabilitation to the southbound structure. In addition to these major components, the existing
gap between the two structures will be eliminated. The result will be a widened deck and
corresponding wider lanes with a raised median separation. This widening of the lanes
effectively removes the perception of a'bottle-neck' to motorists, which will in turn improve the
flow of traffic. The duration of this project is 360 working days and is estimated to be completed
by late summer 2007.
ALTERNATIVE ACTIONS
Other action as determined by the City Council.
FISCAL IMPACT
Grant funds and match funds were previously appropriated. The requested increase and
appropriation of HBRR funds and the corrections to existing grant revenues from 109 funds to
205 funds does not impact the budget.
