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.
