TO: HONORABLE CHAIRPERSON AND MEMBERS OF THE AZUSA UTILITY
BOARD
FROM: MANNY ROBLEDO, DIRECTOR OF UTILITIES
DATE: NOVEMBER 23, 2020
SUBJECT: AWARD OF CONTRACT FOR CAPITAL IMPROVEMENT PROJECT W-354
FOR CONSTRUCTION OF THE TRIANGLE FLOW CONTROL
STRUCTURE
BACKGROUND:
Capital Improvement Project W-354 will automate the operation of several critical water system
valves at Sierra Madre Avenue and San Gabriel Canyon Road. As such, in September 2020, staff
issued Notice of Inviting Bids to contractors for Water Project W-354 Triangle Flow Control
Structure, involving the installation of a new flow control valve, as well as new electrical and
Supervisory Control and Data Acquisition (SCADA) hardware. After completing the formal bid
process, the proposed actions will award the project to the lowest, responsible bidder; and
execute the contract documents.
RECOMMENDATION:
Staff recommends the Utility Board take the following actions:
1)Approve the Award of Contract to Fraijo Brothers, Inc., of Covina, California, for the
construction of Water Project W-354 Triangle Flow Control Structure, in an amount
not-to-exceed $242,407; and
2) Authorize the Mayor to execute the Contract, in a form acceptable to the City
Attorney.
ANALYSIS:
Several critical water transmission mains intersect at Sierra Madre Avenue and San Gabriel
Canyon Road, referred to as the “Triangle.” One of the transmission mains is a 24-inch, low
pressure line, that carries treated effluent water from the Joseph F. Hsu Water Filtration Plant
(Filtration Plant). This line connects to another 24-inch transmission main coming from Azusa

Light & Water’s (ALW) well field; in particular Well 2 and Well 3. The pressure routinely
fluctuates on the transmission main coming from the well field, which affects the flow of water
coming from the Filtration Plant. Currently, when the flow is changed at the Filtration Plant, the
existing isolation valves at the “triangle” must be adjusted manually to compensate for the well
field fluctuations. The existing valves that were installed for isolating the pipelines are not
designed to control flow. ALW staff consulted with Stantec Consulting Services, Inc., under an
existing Professional Services Agreement, to prepare construction plans and specifications for
automation of the current site.
The proposed work consists of constructing a new automated flow control structure, including:
installation of power to the site, electrical, instrumentation, remote terminal unit (RTU), SCADA
communication hardware, a 16-inch Cla-Val flow control valve, connections, tie-ins, removals,
abandonments, appurtenances, street restoration, landscape restoration, traffic control, and all
supplies, equipment, shoring, and transportation necessary to construct and complete the project
titled: Triangle Flow Control Structure Project No. W-354.
On September 21, 2020, the Azusa Utility Board authorized advertisement and solicitation of
bids for Project W-354 Triangle Flow Control Structure Capital Improvement Project. Public
notices soliciting bids started on September 22, 2020. Notices were posted on the City of Azusa
website and published in the San Gabriel Valley Tribune on September 25 and October 5, 2020.
Staff received responses from nineteen potentially interested parties, which included contractors,
sub-contractors, suppliers, and plan holder agencies. A mandatory pre-bid meeting was held via
Zoom teleconference on October 20, 2020; with six contractors in attendance. Three parties
submitted bids by the required deadline on October 27, 2020. On October 27th, at the Azusa City
Clerk’s office near the outside fountain, bids were publicly opened and showed via a live stream
Zoom teleconference. Several contractors, subcontractors and suppliers expressed their
appreciation to ALW for allowing them to view the opening via live stream during the current
pandemic.
The companies and their respective bid pricing, as submitted, are as follows:
1 Fraijo Brothers Inc. $ 242,407.00
2 J. De Sigio Construction $ 314,050.00
3 Stephen Doreck Equipment Rentals, Inc. $ 348,810.00
Fraijo Brothers Inc. was determined to be the lowest, responsible bidder. Based on the package
review and assessment, the lowest bidder met all of the requirements of the contract documents.
Accordingly, Staff recommends that Fraijo Brothers, Inc. be awarded the project.
FISCAL IMPACT:
The fiscal impact of the award of contract is $242,407.00, which includes a standard 10%
contingency. Funding for this project is available in the Water Division’s Capital Improvement
Program, Account No. 32-80-000-721-7145/72120B-7145.
