Geotechnical engineering

ANS Geo’s Geotechnical Engineering Team specializes in providing a solid investigative approach for achieving this goal.

Our approach reduces risks associated with geotechnical design, site development, and construction projects.

  • Subsurface exploration and evaluation
    • Test borings, test pits, Electrical Resistivity Testing (ERT), Infiltration Testing as per State requirements and NYCDEP Green Infrastructure Guidelines.
    • Karst investigations
    • Geotechnical laboratory testing of soil and rock for engineering properties

  • Foundation review, design analysis and recommendations
    • Shallow foundations: spread footings, mat foundation.
    • Deep foundations: driven piles, micropiles, caissons, drilled shafts, helical piles, and auger cast piles.

  • Retaining wall system design and recommendations
    • Sheet pile wall design
    • Soldier pile wall design
    • Support of excavation design
    • Gravity retaining wall design
    • Anchored/mechanically stabilized wall design

  • Earthwork analysis and recommendations
    • Soil stabilization and improvements
    • Excavations and embankment fills
    • Settlement of structures and embankments
    • Site grading, compaction, and restoration

  • Forensic studies and investigations

  • Slope stability analysis and recommendations

  • Seismic review and evaluations

  • Pavement analysis and design

  • Geotechnical Construction Inspection
    • Deep foundation testing and inspections (include GRLWEAP analysis for piles)
    • Earthwork (compaction tests
    • Slope inspection
    • Retaining wall
    • Support of excavations (sheet piles, soldier piles, tiebacks, etc.)
