Replacement of two 100 Ton Chillers - Orange, CA
Two existing chillers systems required replacement. Each chiller was replaced separately to maintain the required cooling to an Orange community Utility building. The chillers are located in a basement mechanical room with their heat-rejection equipment located directly above them. The area way above was re-roofed to establish a leak-proof environment in the chiller room below. The chillers had to be lowered into an area way adjacent to the Chiller room and then set-up in place through the use of rigging.
HVAC Cooling Tower Replacement - Anaheim, CA

Fuel Storage Tanks - Anaheim, California
A 15,000 S.F. (inside & outside of building) project to replace existing Underground Fuel Storage Tanks with new tanks to bring emergency fuel storage system into compliance with new local & state governmental standards. These tanks were for the storage of diesel fuel used to power five diesel electric generators which would power the entire building during any potential commercial power failures; insuring that vital service would not be interrupted to the surrounding community. The exterior excavation to expose the existing underground tanks was 120 feet X 100 feet X 30 feet deep. The excavation was set directly next to existing footings and foundations of a major utility building in downtown Anaheim. Three existing 20,000 gallon tanks were removed and were replaced by two 30,000 gallon tanks. All connecting piping and monitoring equipment between the tanks and the building was upgraded to current standards under the inspection by the City of Anaheim Fire Department, Southern California AQMD,and EPA.
