BOARD AGENDA ITEM 7b
TO: Board of Directors
FROM: Brent Goligoski, Senior Engineer
MEETING DATE: October 17, 2024
ITEM – PROJECT NAME: Aeration Blower System Improvements Project
REQUESTED BOARD ACTION: Authorize staff to prequalify contractors to bid on the
Aeration Blower System Improvements Project.
DISCUSSION: Carollo Engineers and District staff are working to finalize the Bid
Documents for the Aeration Blower System Improvements Project. This project includes
the following improvements at the District’s Wastewater Treatment Plant (WWTP):
Replace the existing engine-driven blower with a new hybrid positive
displacement blower
Replace Blower Building electrical switchgear, including power submetering in
the blower building and elsewhere throughout the treatment plant
Blower building ventilation improvements
Replace and upgrade valving, instrumentation and control for aeration system
Replacement of a large electrical transformer and multiple sets of electrical
switchgear
Replacement or installation of fire alarms in the Blower Building, Filter Building,
Hypo Building, and Small Generator Building
Biosolids Building HVAC and Odor Control System Improvements including
addition of a strobic fan for odor control.
All work will be performed on the WWTP site, while the District continues to operate the
WWTP. This complex project will require the services of a general contractor, an
electrical contractor, and a controls integrator. The Project is expected to cost $8
million.
Based on staff experience, integrating a new control system into an existing,
operational system can be a difficult, risky operation that requires special expertise.
Likewise, award to an unqualified contractor can result in project delays, increased
claims, fines and penalties from regulatory agencies, and diminished quality of the

project. As such, staff recommends that the District prequalify controls integrators for
this project prior to proceeding with the bid period.
Staff expects to advertise for prequalification in October and review results in
November. Staff will return to the Board with the prequalification results for approval
and authorization to bid the construction contract. The project is expected to be
completed in 2025 through 2026.
Staff is currently preparing a prequalification questionnaire, an objective scoring system,
and an appeals process following California Department of Industrial Relations
Guidelines and in accordance with California Public Contract Code Section 20101.
Bidders will only be allowed to name in their bids those controls integrators who have
prequalified to bid the project.
