Item to be presented by: Christopher Ph ce
SUBJECT: SIERRA HIGHWAY BRIDGE(S) OVER THE RAILROAD —
PROJECT NO. S3009 — AWARD DESIGN SERVICES CONTRACT
DEPARTMENT: Transportation & Engineering Services
RECOMMENDED ACTION
City Council award the design services contract for the Sierra Highway Bridge(s) over the
Railroad, Project No. S3009, to Parsons Brinckerhoff Quade & Douglas, Inc. in the amount
of $184,025.00, and authorize a 10 percent contingency expenditure in the amount of
$18,402.50, for a total project budget not to exceed $202,427.50; and authorize the City
Manager or designee to execute all documents, subject to City Attorney approval.
BACKGROUND
Sierra Highway is classified as a major arterial and a Congestion Management Plan (CMP)
route, as well as a truck and super -truck 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. In doing so, the lane widths were reduced
and are consequently substandard.
This project will rehabilitate and/or replace the existing northbound and southbound
bridges on Sierra Highway over the railroad while providing adequate travel lane widths
for motorists and cyclists, as well as 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
indicates that further analysis in determining its most viable design alternative is
warranted. The purpose of this project is to determine the most cost-effective and feasible
design alternative to address the deficiencies of these bridge structures.
Staff mailed a Request for Proposals (RFP) to 45 consultants. Eleven firms submitted
written design proposals to the City. Staff, along with a representative from Los Angeles
County, evaluated all proposals in accordance with the requirements in the RFP. From
these 11 firms, staff interviewed the following top five design firms:

Staff determined that Parsons Brinckerhoff Quade & Douglas, Inc. would best fulfill the
City's needs for the project. Therefore, staff recommends awarding the contract . to
Parsons Brinckerhoff Quade & Douglas, Inc.
Through the Highway Bridge Replacement and Rehabilitation (HBRR) Program
administered by the California Department of Transportation, the City was previously
awarded $492,000.00 of federal funds. These HBRR funds and $123,000.00 in local match
General Fund monies (for a total of $615,000.00) were appropriated by the City Council for
preliminary engineering and preparation of plans, specifications, and estimates during the
Fiscal Year 2001/02 budget process.
Because additional funds may be required to replace the southbound structure, if necessary
Parsons Brinckerhoff Quade & Douglas will reapply for additional HBRR funding on behalf
of the City during Task I of their scope of work. The contract to be awarded at this time is
to include Task I only, which is the Preliminary Design Analysis of their scope of work.
Task I includes project startup and field review, site surveys/right-of-way, geotechnical
investigations, alternative evaluation, and HBRR funding acquisition support. Upon receipt
of Caltrans' response to the City's request for additional project funding, staff will return to
the City Council with a request to appropriate additional project design funds to CIP
Project No. 53009.
ALTERNATIVE ACTION
Other action as determined by the City Council.
FISCAL IMPACT
Adequate funding has been previously appropriated and is currently available to support
this project. Appropriated amounts and sources include $492,000.00 in HBRR funding and
$123,000.00 in General Fund monies.
