Full-Scope Geotechnical Engineering
Soil Borings & Sampling
Standard Penetration Test (SPT) borings, undisturbed Shelby-tube samples, and rock coring across the site footprint, coordinated with utility mark-outs and access constraints.
Geotechnical Lab Testing
AASHTO- and ASTM-compliant lab suite: gradation, Atterberg limits, moisture/density, consolidation, direct shear, triaxial, and CBR testing as scope demands.
Foundation & Retaining Wall Recommendations
Shallow-foundation bearing capacity, deep-foundation options (driven piles, drilled piers, micropiles), lateral earth pressures, and settlement analysis in a signed & sealed report.
Construction-Phase Support
Pre-bid geotechnical clarifications, RFI response during construction, and field observation of subgrade preparation, deep-foundation installation, and compaction.
Typical Project Types
- New commercial, residential, and mixed-use developments
- Building additions, vertical expansions, and reroofs
- Retaining walls, excavations, and SOE design
- Bridge, culvert, and pavement subgrade evaluations
- Deep-foundation and pile-driving programs
- Post-construction settlement and distress investigations
Pairs Naturally With
Phase II ESA
Combine environmental sampling with geotechnical borings in a single mobilization — typical savings of 20–30%.
