The Idaho State Capitol Wings Expansion

The Idaho State Capitol Wings Expansion project included the excavation, waterproofing and core and shell construction of two 25,000 sq ft single level below grade buildings including landscaping.  These underground wings are additions to the East and West sides of the existing State Capitol building providing additional hearing rooms, conference areas, offices, kitchen and dining room, and storage space.  Skylights in the main hallways will utilize natural light.   McAlvain placed 8,000 CY of Concrete during construction.
