02 What we move
Built from the
ground down.
We turn complicated ground into a clean start. Every cut, lift, and finish is planned around the structure, schedule, and people that follow us.
Site Development
From raw acreage to build-ready ground. Clearing, mass excavation, access, pads, and complete site preparation.
Foundation Excavation
Clean cuts, exact elevations, and stable working surfaces for foundations that start right the first time.
Grading & Drainage
We read the water before it becomes a problem, then shape the land to move it exactly where it belongs.
Utilities & Trenching
Precise trenching for water, sewer, electric, gas, and communications with a clean, coordinated backfill.
Demolition & Clearing
Controlled removal, responsible sorting, and a clean site left ready for the next phase—not the next problem.
Rock & Retaining
Rock excavation, boulder work, retaining systems, and difficult terrain handled with the right iron and judgment.

05 How we work
Nothing
left to
chance.
Dirt work is permanent work. Our process removes uncertainty before it becomes an expensive surprise.
Read the land
We walk the site, study access, drainage, grade, soils, and what the plans don't say out loud.
Plan the cut
Quantities, equipment, sequencing, export, and finish elevations are mapped before tracks hit dirt.
Move with precision
Experienced operators execute cleanly, communicate early, and keep the site moving without chaos.
Leave it ready
The final grade is checked, the site is cleaned, and the next trade can start without fixing our work.

06 The ground truth
Operators who think like builders.
Obsidian Grade was founded on a simple belief: excavation should make every phase after it easier. That means thinking beyond the bucket, respecting the plans, and leaving a site we'd be proud to build on.
Field-led
Decisions stay close to the work, not trapped in an office.
Schedule-minded
We protect the critical path and communicate before issues spread.
Built to finish
We plan every rough move around the final result.
