Council Meeting: October 25, 2005 Santa Monica, California
TO: Mayor and City Council
FROM: City Staff
SUBJECT: Construction Related Contracts for the Centinela Avenue Urban Runoff
Mitigation Project
Introduction
This report recommends that the City Council award a construction contract to Blios
Construction, Inc., the best bidder, in the amount of $1,199,000 plus a 10% contingency
amount of $119,900 to construct a treatment facility for the Centinela Avenue Urban Runoff
Mitigation Project. This report also recommends that the City Council authorize the City
Manager to negotiate and execute a construction management agreement with DMR Team
in an amount not to exceed $135,000 plus a 10% contingency amount of $13,500 for the
project.
Background
The City received grants from the California Integrated Waste Management Board and
Proposition 12 in fiscal year 2001 and Proposition 13 in fiscal year 2004 to implement an
urban runoff pollution mitigation system for dry weather flows from the Centinela Basin
Watershed entering nearby Ballona Creek, the receiving water body for the City?s eastern
border which outlets to the Santa Monica Bay. Both bodies of water have degraded water
1
quality and are included on a national list of impaired water bodies that should be
remediated.
In fiscal year 2003, the City contracted with Black & Veatch Corporation to design a
pollution mitigation device on the existing Centinela Avenue storm drain system and
examine alternative sites which would best meet the project?s objective of improving water
quality.
The consultant concluded that two potential sites for the project existed: one along Virginia
Avenue north of the Santa Monica Freeway in the City of Santa Monica, and another in
Mar Vista Park in the City of Los Angeles. City staff evaluated benefits and drawbacks for
the treatment system in each location and concluded that the Mar Vista Park site was the
preferred site as it offered open space for construction, easy access for operation and
maintenance, few if any utilities conflicts, an adequate level of runoff flow for year-round
treatment, and close proximity to the open Sepulveda Channel for flood relief. The City
entered an inter-agency agreement with the City of Los Angeles Parks & Recreation and
Watershed Protection Divisions, and the County of Los Angeles Watershed Management
Division to obtain approval to use the Mar Vista Park site for this project that benefits the
entire region. The City of Los Angeles has agreed to grant Santa Monica an easement for
the installation and maintenance of the urban runoff mitigation system on City of Los
Angeles-owned property.

Discussion
Construction Contract
A Notice Inviting Bids for the construction contract was published on July 9 and 15, 2005,
in The Los Angeles Times. Twenty-two contractors requested bid packages and seven
sealed bids were received by the City Clerk's office and publicly opened on August 24,
2005, by the Deputy City Clerk.
The bid results were as follows:
G.B. Cook, Inc. $ 1,020,592
Blios Construction, Inc. $ 1,199,000
Los Angeles Engineering, Inc. $ 1,281,990
SDR Engineering, Inc. $ 1,297,648
Clarke Contracting Corporation $ 1,367,296
Garcia Juarez Construction, Inc. $ 1,490,570
Southwest Engineering, Inc. $ 1,539,508
City Engineer's Estimate $ 1,200,000
G.B. Cook, Inc., submitted a letter to the City requesting that their bid be withdrawn
because of a mathematical error. The City Attorney?s office reviewed the letter and
3
concurred.
Blios Construction, Inc., the best bidder, provided the City with six references. City staff
contacted the references and they all reported that the contractor's work was completed in
a timely and cost-efficient manner while maintaining consistent quality. The contractor is
currently working for the City of Santa Clarita at Stetson Ranch Sand Canyon on a $3
million storm filtration installation project. Other projects successfully completed of similar
scope and scale include: two storm water treatment units for the City of Santa Clarita; the
Yucca Street storm drain for the City of Oxnard; a 48 inch storm drain for the County of
Ventura; and the Magic Mountain pipeline for the Castaic Lake Water District .
The State Contractors' License Board verified that the contractor's license is current,
active, and in good standing. City staff also contacted the Center for Contract Compliance
and found the contractor is in good standing and capable of handling labor compliance
issues.
Construction Management Agreement
In July 2005, the City requested proposals from qualified firms to provide construction
management services for the Centinela Avenue Urban Runoff Mitigation Project. Four
firms submitted proposals. City staff reviewed the proposals and interviewed all four firms.
Following the interviews, DMR Team was selected as the top ranked firm to provide
4
construction management services for the construction of this project. These services
include construction oversight and continuous inspection of the contractor?s work during
construction of storm drain lines; managing traffic control and detour plans; reviewing
submittals and change order requests; conducting periodic progress meetings; providing
information to the contractor on an as-needed basis; and maintaining all necessary project
documentation relevant to the work conducted during construction.
DMR Team?s past performance on several City projects including the Pico Boulevard
Streetscape, Federally Funded Street Improvement ? Phase IV, Fourth Street Traffic
Modification, and the Annual Water Main Replacement has been excellent.
Budget/Financial Impact
Approximately 90% of the project cost is funded by the California Integrated Waste
Management Board, Proposition 12 and Proposition 13 grants. The balance is funded by
the storm water account.
