DirtWorks General Engineering

The Art & Science of Earthwork.

Class “A” General Engineering Contractor — CSLB #1048702. San Diego–based civil consulting, machine-control modeling, drone topography, and self-perform earthwork.

What we do

Four disciplines. One earthwork practice.

From the first line on a takeoff sheet to the last pass of a finish blade, we operate the full stack of earthwork — so the model in the cab matches the math in the bid.

01 / Consulting

Takeoff & Budgeting

Professional civil consulting — quantity surveys, bid item lists, and pre-construction budgets your estimators can actually defend.

02 / GPS

Machine-Control Models

Detailed grade models built from plans and survey — tied to your control network, drop-in ready for Trimble, Topcon, and Leica machine control.

03 / Drone

Drone Topo & Quantities

Photogrammetric topo flights for earthwork quantities, progress documentation, and as-built verification — survey-grade and stamped.

04 / Build

Earthwork & Site Contracting

Self-perform earthwork, site improvements, and underground utilities — Division 31, 32, and 33 scope under a Class “A” license.

Our Mission

The Art & Science of Earthwork.

“The art is in the read — how a site moves, where the water wants to go, what the operator can hold. The science is in the numbers — bank, swell, shrinkage, mass haul, cycle time. We do both. Every job.”

By the numbers

Built on rigor, not guesswork.
