Structural Repairs, Building 3A Headquarters Complex

Camp H.M. Smith, Marine Corps Base Hawaii

Forensic geotechnical investigation for the structural repairs to a 3-story headquarters building built in the 1940s.
Building experienced large amounts of differential settlement and distress since it was constructed.
Extensive cracking in columns and beams, uneven floors, wallboard cracks, and other distress.
Investigation included subsurface borings, test pits, in-place testing, laboratory tests, analysis, reports, and design consultation.
Developed a unique underpinning system to re-support the building to reduce future settlements.
Consultation during construction including innovation pile group testing of the new underpinning micropiles.
