ORA provided a geotechnical engineering study for a future emergency room expansion. Our scope of services included a reconnaissance of the site, a review of geologic literature, drilling of two borings, and preparation of a geotechnical design report. We also provided on-call geotechnical and structural inspection and testing services during construction. The engineering services were performed by ORA to provide the following information:

  • seismic design considerations including liquefaction potential
  • suitable foundation systems with estimated settlements
  • allowable bearing capacity for the design of shallow foundations
  • recommendations for the design of deep foundation (augercast piles, grouted micropiles, and driven steel pin piles)
  • lateral earth pressures and friction coefficients for the design of below-grade walls and retaining walls
  • influence of groundwater on the development
  • site preparation and earthwork recommendations, and
  • project specification preparation related to grouted micropiles and driven steel pin piles.
The structural inspection and testing services performed by ORA included the following items:
  • Soils compaction
  • Moisture testing
  • Reinforced concrete
  • Structural steel erection
  • Fireproofing
