BACKGROUND
Two (2) air conditioning units serving the gymnasium are currently non-functional. Based on
diagnostic assessment, full replacement is required to restore proper cooling, ventilation, and
heating to the space. The scope of work includes design for the new replacement units and
associated equipment, all necessary mechanical, electrical, and controls work to ensure
complete and functional system integration. This may also include ductwork design, structural,
and drain design. The selected engineering must carry all engineering services under their
contract.
This project was previously bid by the City for construction. The intent was to replace the units
with the same models. After bidding, the mechanical contractors advised that the existing model is
no longer allowed in California due to its refrigerants not meeting the current requirements. The
new equivalent model has a larger footprint, less heating capacity, installation requires extensive
reconstruction of the concrete pad, and utility relocation. The selected engineering firm must
provide a turnkey design.
