REPORT TO THE REDEVELOPMENT AGENCY
TO: Redevelopment Agency
FROM: Ron Molendyk, Executive Director
DATE: June 8, 1993
SUBJECT: San Jacinto River Channel Construction
BACKGROUND
The City of Lake Elsinore is re- constructing the Lakeshore Drive
bridge over the San Jacinto River Channel. In order to protect the
new bridge from washout which would result from a 100 year storm,
the San Jacinto River- Channel must be constructed between the
bridge and the Lake Inlet Channel.
DISCUSSION
A contract has been awarded to -Paul Hubbs Construction Company to
construct the San Jacinto River Channel between Lakeshore Drive and
the Lake Inlet Channel. They will construct a temporary earthen
dam in the Lake Inlet Channel, dewater the entire channel,
construct the channel and construct a sheetpile and rock spillway.
Several engineering firms have submitted proposals for performing
the construction management, geotechnical and inspection services
for the subject project. The best proposal was received from Robert
Bein, William Frost & Associates in association with Ninyo & Moore,
geotechnical consultants. A Scope of Services is attached.
FISCAL IMPACT
Construction Management, Geotechnical and Inspection services will
be done on a time and material basis, with a fee Not to Exceed:
Robert Bein, William Frost & Associates . . . . . . $ 72,900
Ninyo and Moore . . . . . . . . 35,260
Funds are available in the 1992/93 RDA budget.
Award a contract' to Robert Bein, William Frost & Associates in
association with Ninyo & Moore for time and materials in an amount
Not to Exceed $108,160.

V. PROPOSED SCOPE OF SERVICES
The purpose of our services will be to observe and test the earthwork construction and
concrete placement. Based on our understanding of the project, the project specifications,
and our experience on similar projects, we propose to conduct the following services:
Provide experienced soil and concrete technicians to conduct in -place density tests for
relative compaction during fill placement, and to collect concrete sample cylinders for
compressive strength testing. The technicians will document the earthwork and
conduct compaction testing using nuclear gauges and/or sand cones. The aggregate
gradation, air content, temperature, unit weight, slump, and chloride ion content of the
concrete will be measured as outlined in the project specifications.
Provide Iaboratory testing as necessary. The anticipated testing will include maximum
density /optimum moisture content, sieve analysis, hydrometer analysis, specific gravity,
durability index, and compressive strength testing.
Provide project management and field coordination by our Project Geologist. The
geologist will coordinate personnel scheduling and laboratory testing, and will also
oversee the general progress of the project while observing and documenting site
conditions, and will be available to address unanticipated site conditions as they may
arise.
Prepare a written report upon completion of the earthwork and concrete construction
documenting our observations and test results. If appropriate, recommendations
regarding geotechnical aspects of the project will also be provided.
