What is GPS grade control?

GPS grade control uses a digital site model and positioning equipment to help operators match plan elevations and slopes in the field. It supports accuracy and helps reduce rework.

Do you do both rough and finish grading?

Yes. We handle grading from initial rough cut through finish and pad preparation.

Can you grade for drainage?

Grading for positive drainage and designed slopes is a core part of the work we perform.

How it goes

Our approach to grading

Model & control

A grade model and control points guide the machines and crew.

Rough grade

The site is brought close to design elevations.

Finish grade

Surfaces are trimmed to tolerance for pads, drainage and paving.

Verification

Grades are checked against the model before handoff.
