RE: APPROVAL OF PROPOSAL TO PROVIDE ENGINEERING SERVICES
FOR THE RECONSTRUCTION OF HELLMAN AVENUE BRIDGE OVER
ALHAMBRA WASH
Attached for your consideration is an engineering proposal from Willdan for engineering
design, design and construction survey, geotechnical engineering, hydrological/hydraulic
evaluation, environmental study, utility coordination, contract administration, construction
observation, and federal labor compliance services for replacement of the Hellman Avenue
Bridge over Alhambra Wash.
The Hellman Avenue Bridge over Alhambra Wash was originally constructed in 1936, with
additional reconstruction performed in 1953. The bridge consists of a single span
approximately 35 feet wide and 49 feet long, with steel girders supporting a reinforced
concrete deck. There are 5-foot sidewalks on both sides of the bridge.
The Hellman Avenue Bridge is currently on Caltrans Eligible Bridge List (EBL) and has
been deemed structurally deficient, with a sufficiency rating of 34.1. The Caltrans EBL
classifies abridge as structurally deficient when its sufficiency rating is below 80. Bridges
with a sufficiency rating between 50 and 80 are recommended for rehabilitation and
retrofitting; bridges with a sufficiency rating below 50 are recommended for replacement,
as is the case with the Hellman Avenue Bridge. The Hellman Avenue Bridge is
programmed through the Highway Bridge Rehabilitation and Replacement (HBRR)
Program to be replaced.
Conceptual investigation thus far indicates that the most feasible replacement solution is to
provide precast prestressed "I" girders supporting a reinforced concrete deck. The
proposed bridge width would be 60 feet within the entire existing right-of-way, and this

width would provide shoulders and sidewalks. It is anticipated that Hellman Avenue will be
closed during construction. Evaluation of the impact of construction within Alhambra Wash
will be conducted and will include code compliance for such issues as containment of
waste or hazardous materials.
The total construction cost for this project is estimated to be $1.0 million and the estimated
contract period is 100-working days. The proposed project is currently programmed in the
Agency's Fiscal Year 2001-02 budget, where the funds are allocated for non-construction
related activities. The project's construction costs will be funded by the Highway Bridge
Rehabilitation and Replacement (HBRR) Program, except for the local matching funds,
which will be funded by the Agency. Construction of the project is anticipated to occur in
the Summer of 2002.
The proposed fees are as follows:
•
Preliminary and Final Design
$75,000
•
Design Survey
4,500
•
Geotechnical Engineering
11,800
•
Hydrological/Hydraulic Evaluation

•
Contract Administration

•
Construction Observation

portion of the City's agreement with Willdan, which pertains to design engineering services.
RECOMMENDATION
It is recommended that the Rosemead Redevelopment Agency approve the attached
engineering proposal and direct staff to begin the preparation of the necessary plans and
specifications.

Subject: Proposal for Professional Engineering Services for the Replacement of Hellman
Avenue Bridge over Alhambra Wash
Dear Mr. Tripepi:
As requested, Willdan is pleased to submit this proposal to provide professional engineering
design, design and construction survey, geotechnical engineering, hydrological/hydraulic
evaluation, environmental study, utility coordination, contract administration, construction
observation, and federal labor compliance services for the replacement of the Hellman Avenue
Bridge over Alhambra Wash.
The Hellman Avenue Bridge over Alhambra Wash was originally constructed in 1936 with
additional reconstruction performed in 1953. The bridge consists of a single span approximately
35 feet wide and 49 feet long with steel girders supporting a reinforced concrete deck. There
are 5-foot sidewalks on both sides of the bridge.
The Hellman Avenue Bridge is currently on Caltrans' Eligible Bridge List (EBL), and has been
deemed structurally deficient, with a sufficiency rating of 34.1. This bridge is programmed
through the Highway Bridge Rehabilitation and Replacement (HBRR) Program to be replaced.
Conceptual investigation thus far indicates that the most feasible replacement solution is to
provide precast prestressed "I" girders supporting a reinforced concrete deck. The proposed
bridge width would be 60 feet within the entire existing right-of-way, and this width would
provide shoulders and sidewalks. It is anticipated that Hellman Avenue will be closed during
construction. Evaluation of the impact of construction within Alhambra Wash will be conducted
and will include code compliance for such issues as containment of waste or hazardous
materials.
