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 finished project involved constructing a new automated flow control structure, including:
installation of power to the site, electrical, grounding, electrical meter, 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 Water 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. On
October 27th, at the Azusa City Clerk’s office, bids were publicly opened outside and showed
via live stream through Zoom teleconference. At the November 23, 2020 Azusa Utility Board,
the contract was awarded to Fraijo Brothers, Inc., for a bid amount of $242,407. Submittals for
the project, procurement of materials, kick off meeting, and obtaining the encroachment permit
took place in February and March of 2021. Staff issued the Notice to Proceed on April 19, 2021
with an effective start date of May 3, 2021. The pre-construction meeting was held on May 6,
2021. The contract time of completion was 60 calendar days, to be completed by July 2, 2021.
Fraijo Brothers finished the project ahead of schedule and under budget on June 14, 2021.
FISCAL IMPACT:
The Triangle Water Flow Control Structure Capital Improvement Project was budgeted in the
Water Division’s 2021 Fiscal Year Capital Improvement Program, Account No. 32-80-000-721-
7145/72120B-7145 for $650,000. The total amount awarded for construction of W-354 to Fraijo
Brothers, Inc. was $242,407. Total project costs were $228,089, which resulted in a savings of
$14,318.
