The installation of air conditioning at The Mendota Mental Health Facility was the first phase of a new, central campus chilled water system. Existing conditions made the project very challenging. Ductwork placement was complicated because of low floor-to-floor height and a high level of existing electrical systems within the corridor ceilings for nurse call, fire alarm and security systems. A six-phase construction schedule was necessary to accommodate partial occupancy without sacrificing security.

Other improvements included high security windows, an engineered smoke control system, and an upgraded roof structural system to carry the increased load of a new mechanical penthouse.
