C-17 Hangar, Phase 1
March Air Force Base, CA
This Design/Build project consisted of a 53,066 sf hangar to service C-17 transport airplanes. The project included extending/modifying six environmental monitoring wells and incorporating them into the hangar slab-on-ground, complete 10-inch diameter aircraft rated valve box frames and covers, and installing all new lighting, concrete foundation and floors, site utilities, mechanical, HVAC systems, plumbing, electrical power systems, and fire alarm system with fire sprinkler system and HEF aircraft fire protection systems. A sanitary sewer-lift station, complete with all associated wet and dry wells, manholes, piping, plus required appurtenances was included as well as an Aircraft wash-water industrial waste treatment plant (IWTP). Hangar bay utilities included breathable air, compressed air, electrical power, natural gas, and aircraft hot-water power washing equipment.

Aircraft Armament Test & Maintenance Facility
Yuma Proving Ground, AZ
This Design/Build project was for an aircraft test and maintenance hangar. The hangar foundations are shallow-type spread footings and continuous footings proportioned for gravity and lateral load resistance. Two aircraft load-rated power pits supply 60Hz, 400Hz, 28V dc power and communications connections between the three green pads on the apron. In addition, construction included an asphalt surface parking lot, a 57,600 sf concrete apron and taxiway with two Fire Department access roads to the apron, three helicopter staging areas with tie-downs, grounding points, power and communications, and an oil/water separator to capture discharge from the hangar bay areas.
