SYSTEMS RETROFIT PROJECT (PHASE 1) – APPROVE PLANS AND
SPECIFICATIONS AND AUTHORIZE SOLICITATION FOR BIDS
RECOMMENDATION:
That the City Council approve plans and specifications and authorize solicitation for bids
for Cash Contract No. 674 – Downey Theater and Public Library Heating, Ventilation
and Air Conditioning (HVAC) Systems Retrofit Project (Phase 1).
BACKGROUND:
The HVAC systems for the Downey Theater and Public Library have well exceeded
their useful life; are inefficient in energy consumption and operation; and require
constant maintenance and repair. The City hired an engineering consulting firm to
evaluate the HVAC systems and design their retrofits. Below is a description of the
work required to retrofit the systems:

DISCUSSION:
The main objectives of the project are: (1) to improve the overall efficiency and reliability
of the HVAC systems by replacing existing outdated, inefficient and unreliable
equipment with more technologically advanced, efficient and reliable equipment, and (2)
to repair existing leaking ducts and pipes.
The estimated cost for completing all necessary work far exceeds the current available
funding. As such, the project has been broken down into two phases. The first phase
includes replacement and repair of HVAC components which must be addressed
immediately. Phase 2 of this project can be completed when funds become available.
Phase 2 includes replacing air handling units, condensing units, additional cooling coils,
evaporative condensers, additional testing and repairing of ducts and pipes, hazardous
materials mitigation, and design and inspection fees. Phase 2 of this project would cost
approximately $2,000,000 to complete.
The plans, specifications and construction cost estimate for Phase 1 of the Project have
been prepared and the City is ready to solicit bids for construction.
FINANCIAL IMPACT:
Based on the construction cost estimate, the total cost for the Downey Theatre and
Public Library HVAC Systems Retrofit will be $1,014,000. This includes the cost of
evaluation, design, construction, project administration, inspection, City furnished
material and contingencies. This project will be funded through an Energy Efficiency
and Conservation Block formula-based Grant (EECBG). A detailed cost estimate will be
presented to the City Council at the time of the award of the construction contract for
this project.
