Moses Engineers designed the mechanical, electrical, plumbing (MEP), fire protection and special systems for Lockheed Martin’s $30 million satellite assembly facility.  It took only two years to complete this massive project. 

This 310,000 sq. ft. metal frame building is constructed on a contiguous concrete slab with multiple roof lines to accommodate satellite assembly. There are eight clean rooms covering over 60,000 sq. ft. (1,920,000 cu. ft.) with ceilings over 40 ft. tall. Clean room supply air meets the ASHRAE standards and involves 30% pre-filters, 85% final filters and 99.97% HEPA filters. A unique design deleted the heating and cooling coils from the large air handling units serving these clean rooms. This was accomplished by using outdoor air units equipped with cooling and heating coils and heat pipe to provide the positive pressurization and the heating and cooling required. This saved initial costs and continuing energy costs by not having to cool the air to get to the proper humidity levels and re-heating this same air to achieve proper space temperatures.

Mechanical systems includes:

  • two 900 ton chillers, a 365 ton chiller for after hours use and two heating hot water boilers rated at 7,000,000 and 3,000,000 BTU/Hr. 
  • industrial gas designs including systems for nitrogen, compressed air, vacuum air, argon, helium and deionized water.

The electrical system provides:

  • a highly reliable, clean power system while minimizing operating costs.
  • a diesel generator supplying emergency power for lights and selected loads, through an ATS
  • a battery UPS providing support for critical loads separate from the generator.

Special design features included to provide for clean power:

  • state-of-the-art harmonic mitigation filters
  • a special static drain ground system using insulated ground cable extended into labs and clean rooms and attached to the ground loop. 
  • volt panels that act as surge suppression devices negating the need for individual surge suppressors throughout the facility.
