Garco Construction was the prime contractor hired for the Joint Base Lewis-McChord Regional Logistics Support Complex project. It utilized both Design-Build and Design-Bid-Build project delivery methods. The structural foundations, steel frame and exterior cladding and insulation systems were Design-Build and the remaining scope was Design-Bid-Build.
The project consists of two nearly identical buildings that each include a two-story office building structure with attached high bay tactical equipment maintenance bays for mixed-use by the Army Field Support Brigade. Totaling 155,500 SF, the Complex features 44,000 SF of office space including command level offices, open office, walled in offices with demountable partitions, secure conference rooms, computer rooms, classrooms, secure command closets, testing laboratories, restrooms, breakrooms, communications rooms and SIPRNet rooms. The remaining 111,000 SF of the complex features two heavily reinforced concrete arms vaults, lube and gear oil rooms, storage and support space, electrical and mechanical rooms and 56 work bays supported by four 10-ton overhead bridge cranes, one 25-ton overhead bridge crane, 27 one-ton jib cranes and 11 in-ground maintenance pits.
The mechanical and electrical systems combined with the thermal insulation system and exterior glazing are optimized for energy efficiency in accordance with the U.S. Green Building Council’s LEED-Certified standards. The design and construction meet LEED Gold Certification requirements, featuring geothermal ground source water heating and cooling and rainwater collection systems.
