Geotechnical engineering investigates subsurface conditions — soil types, bearing capacity, groundwater, and expansive or problematic soil conditions — and translates those findings into foundation recommendations, earthwork specifications, and design parameters for structural and civil engineers. Apex Grid provides geotechnical engineering for commercial, multifamily, industrial, and government projects.
Request Engineering SupportGeotechnical engineering investigates what's below the surface of a site — the types, strengths, and behaviors of soil and rock — to inform the design of foundations, retaining structures, pavement, and earthwork. A geotechnical investigation involves drilling soil borings, collecting samples, performing laboratory testing, and producing a geotechnical report with foundation recommendations and engineering parameters. The geotechnical report is a prerequisite for structural foundation design on most commercial projects and is required by most building departments.

Apex Grid Engineering is licensed in 49 states — every U.S. state except Alaska. Engineering stamping and licensure are confirmed for each project jurisdiction. We provide geotechnical engineering as a standalone service or as part of a coordinated multi-discipline package.
We work from architectural PDFs, contractor sketches, or existing CAD files and produce stamped engineering documents and permit packages that building departments accept. One business day turnaround on fee proposals.
