Pavement Subgrade Evaluation and Geotechnical Engineering

What This Engineering Scope Covers

Subgrade soil classification and characterization
R-value testing for flexible pavement design
CBR testing for flexible and rigid pavement design
Pavement design calculations — AASHTO or mechanistic-empirical
Heavy truck vs. light vehicle pavement design
Subgrade improvement recommendations for weak soils

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 is included when I hire Apex Grid for this work?

This scope covers subgrade soil classification and characterization, r-value testing for flexible pavement design, CBR testing for flexible and rigid pavement design, and pavement design calculations — AASHTO or mechanistic-empirical.

When is this engineering needed?

Pavement subgrade evaluation characterizes the soil that the pavement structure will be built on — providing the design parameters needed to produce a pavement section that performs under the expected traffic loading.

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.

Does Apex Grid confirm licensure for my 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.
