Detailed Scope of Work

The scope of this project is to provide air conditioning and a new 480 volt, 3-phase power service to the city national civic auditorium (aka San Jose Civic Auditorium). With the historical value of this building, it is imperative to maintain the present design with a minimum impact to the architectural features, both inside and out, while providing the cooling and power to the building.The scope of this project is to provide air conditioning and a new 480 volt, 3-phase power service to the city national civic auditorium (aka San Jose Civic Auditorium). With the historical value of this building, it is imperative to maintain the present design with a minimum impact to the architectural features, both inside and out, while providing the cooling and power to the building.

The current installation for the HVAC system is 100% ventilation with steam heating coils at the outside air intakes with an individually controlled ducted three zone system; each zone with its own fan and heating coils. With the exception of relocating some existing steam condensate return and the deletion of some coils in the basement, the existing steam boiler and steam system shall remain in its present configuration. The project will incorporate the addition of a new chiller, cooling coils and re-configuration of one supply fan to become a return fan. The project includes a complete controls upgrade for the building built up air handler, chillers, pumps and new stage ahu.

The current installation for the electrical power is a 208-230 volt, 3 phase service. All existing to remain components shall remain with their present power requirements ; there will be a 208-230 volt, 3 phase step down transformer being fed from the new 480 volt, 3 phase transformer. A single electrical service shall continue to the building with power.
