Quad E, Schofield Barracks Renewal


FY05 MCA PN 52263, Buildings 549 thru 552, Whole Barracks Renewal, Phase 4B and 4B2, Quad E, Schofield Barracks, Island of Oahu, Hawaii

  • Client: U.S. Army Corps of Engineers
  • Contract Amount: $64,130,000

The Whole Barracks Renewal, Phase 4B/4B2 project consisted of the complete renovation of the four buildings that make up the historic quadrangle known as “Quad E”. Built in 1920 and totaling 340,000 square feet, the Quad is a significant structure in Schofield Barracks and listed in the National Register of Historic Places. Originally designed as an open bay barracks complex with endless rows of bunks, the facility has been modernized through this project into a two individual bedroom unit configuration, which share a private bathroom and a full kitchen equipped with a range oven. These apartment-like barrack units occupy two of the buildings in the Quad, serving up to 300 soldiers, while the other buildings house two Battalion Headquarters, seven Company Operation Facilities, several classrooms and conference rooms, a gymnasium, and a central plant. Other amenities included large parking lots with vehicle access control to meet anti-terrorist requirements, two exterior basket ball courts, and a barbecue pavilion.

Because the structures were both historically significant and correspondingly code deficient, the largest challenge encountered involved properly upgrading the buildings to meet current building and seismic codes, while retaining the original façade and features. To accomplish this, a technique known as shotcrete was utilized, where the new structural walls were shot on the interior side of the existing structure much like a swimming pool. The result was essentially creating a new 8-inch concrete structure within the existing concrete shell.

Due to the success of the project, Nan, Inc. was presented with a Historic Preservation Honor Award from the Historic Hawai’i Foundation.
