The facility includes a 23,300 SF administration/operations building and a 25,000 SF fleet/shop building with maintenance bays and vehicle wash bay. In addition, the project has achieved USGBC LEED V2.2 Gold. The geothermal heat pumps located beneath the employee parking area is comprised of 40 wells and provides efficient heating and cooling to the administration/operations building. Future roof stub-outs and interior space is allocated to accommodate future PV inverters and roof array. The project included a slow-fill CNG station with twin and quad hose bollard mounted fill dispensers. Henderson Engineers designed the natural gas and electrical infrastructure and coordinated with the gas utility to determine line sizing and metering requirements for the CNG station. Included in the infrastructure design was a complete report on the impact of NFPA 52 code requirements and FM insurance requirements for the public project. The project also contains two canopy covered fueling stations with multiple fuel pumps.
Henderson applied sustainable site master planning services for this project: Water recovery analysis with the equipment manufacturer for the vehicle wash bay, site wind patterns, solar, daylighting, and geothermal studies assisted in determining the optimum building placement and site orientation. Henderson worked closely with the manufacturer to identify critical items such as specific to the wash-bay: sizing the wash bay and adapting it to the overall building structure and environment, vehicle types to be washed, peak number of vehicles per hour, total number of vehicles per day/week/month.
The manufacturer had stringent re-use system standards where their typical reuse system recycled most (90-95%) of the water for the wash process and utilize a fresh water rinse cycle for the final rinse. Henderson designed the building systems to help meet this standard- it is for implementation at a later date and a traditional system was favored for the time-being.
