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.
