How Apex Grid Handles This

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 engineer geotechnical engineering scopes as a standalone service or as part of a coordinated structural, MEP, civil, and geotechnical package.

We work from architectural PDFs, contractor sketches, or existing CAD files and produce stamped engineering documents, permit drawings, and calculations that building departments accept the first time.

Frequently Asked Questions

What does this engineering scope cover?

This scope covers atterberg limit testing to characterize expansive potential, plasticity index and linear shrinkage evaluation, swell pressure testing for foundation design, and foundation type recommendations for expansive soil sites.

When is this engineering needed?

Expansive soils — particularly the clay soils common in Texas, Arizona, Colorado, and the Southeast — swell when wet and shrink when dry, causing more foundation damage nationally than earthquakes and floods combined.

What does Apex Grid deliver for this scope?

Stamped engineering documents, permit drawings, and calculations. We work from architectural PDFs, contractor sketches, or existing CAD files. We engineer geotechnical engineering scopes as a standalone service or as part of a coordinated structural, MEP, civil, and geotechnical package.

Is Apex Grid licensed for my project's jurisdiction?

Apex Grid Engineering is licensed in 49 states — every U.S. state except Alaska. Engineering stamping and licensure are confirmed for each project jurisdiction.
