GSG delivered comprehensive geotechnical services along a 26.2-mile alignment, advancing 365 borings to depths of 50 to 70 feet.

Scope of Services

• • Scope included drilling according to a drilling access plan, HASP mobilization, and conducting in-situ pressure meter testing per ASTM D4719
  • Analyzed the data to provide recommended modulus values and followed up with boring grouting, site restoration, and a full suite of geotechnical lab testing—including moisture content, Atterberg Limits, density, sieve analysis, soil/rock compression, resistivity testing, and corrosion testing
  • The project concluded with the submission of a detailed Geotechnical Report for Phase I and Phase II design
