Schofield Barracks, Hawaii


This $58 million design-build project includes two facilities: a 72,000 SF, 120-person, 60-unit, five-story Warriors in Transition (WIT) Barracks and a 42,000 SF, four-story building that house a Soldier & Family Assistance Center, and a WIT Complex that is a combination facility consisting of two-medium Company Headquarters and a Battalion Headquarters.  A central plant was also included in the scope of work.  The design of the buildings comply with UFC Department of Defense Minimum Antiterrorism Standards for Buildings (UFC 4-010-01) and Unified Facilities Criteria Design of Buildings to Resist Progressive Collapse (UFC 4-023-03).  The Barracks was predominately cast-in-place concrete with insulated concrete form (ICF) exterior walls and the WIT Complex was a steel framed building with concrete filled metal deck and ICF exterior walls.

Client Benefits

Our services included full structural design, analysis and production of construction documents using 3D Revit models coordinated with all design disciplines. BASE was also the AT/FP consultant for the project, which included progressive collapse mitigation and blast design.  Furthermore, BASE provided quality control, special inspections and material testing during construction.  Our quality control specialist was on site full time throughout the structural work and interacted closely with the contractor and our design engineers to resolve field issues in an efficient and seamless manner.  Having BASE staff responsible for the design, quality control and special inspections ensured that critical and unique structural details were appropriately constructed as designed.     

The Science and Design of Structural Engineering

ICF walls were primarily utilized for their enhanced energy performance compared to other exterior wall types. ICF construction is very streamlined and typically used for small residential applications.  Integrating ICF into two high performance multi-story buildings designed to resist the demands of high seismic/winds loads and progressive collapse avoidance was a challenge. Further increasing the challenge, the project also had a very aggressive schedule.  BASE worked closely with the contractor, ICF consultant and concrete supplier to deliver a final design that not only met all applicable codes and DoD criteria, but was efficient and easy to build while still working within the constraints of ICF construction.
