Industrial & Commercial Sitework

Everything between raw ground and a site that is ready to build on — cleared, dug, stabilised, drained and graded to plan.

The whole site, one contractor

Sitework is the collection of trades that has to happen before vertical construction starts, and the usual failure is coordination: the clearing contractor leaves, the utility contractor cannot get in, the grading crew reworks what the utility crew disturbed, and three weeks disappear. We do the whole package with our own people, so that handoff does not exist.

A typical commercial site with us looks like this: clear and demolish what is there, strip and save the topsoil, cut the site to subgrade, put the underground utilities in, backfill and compact, shape drainage, then grade to finish tolerance and hand a certified pad to the building contractor.

Industrial and municipal work

We work on industrial sites where the tolerances and the documentation matter — warehousing and distribution, processing facilities, port and river-front development, public infrastructure. That means compaction testing, grade certification, traffic control and erosion control done properly, and a superintendent who can talk to an inspector.

Demolition

Structures, slabs, foundations, pavement and underground tanks. Where the material can be crushed and reused on site as structural fill or road base, we do that with our own crushing equipment — it takes trucks off the road and takes cost out of the job.

Building pads

The pad is what your building sits on and what your structural engineer signs off. We build them to spec, compaction tested, at the elevation the plans call for — whether that is a pad for a 200,000 square foot warehouse or for a 40 by 60 shop.

Common questions

Questions we get asked

What is included in sitework?

Everything that turns raw or previously developed ground into a site ready for vertical construction: clearing, demolition, excavation, underground utilities, drainage, stabilization, base placement and final grading.

Do you do demolition on its own?

Yes. We take structures, slabs, foundations and pavement, and we can crush concrete and asphalt on site for reuse instead of hauling it to a landfill.

Can you handle the underground utilities too, or do I need a separate contractor?

We do them ourselves. Water, sewer, storm and franchise utility trenching and installation are part of our normal scope, which is the main reason sites we run stay on schedule.

Do you provide compaction testing and grade certification?

Yes. Testing is coordinated as part of the work and documented so your engineer and the inspector have what they need.

How early should I bring you in?

Earlier than most people do. If we see the civil drawings before they are final we can often flag things that cost real money — an unbalanced site, a drainage design that needs import, a pad elevation that adds thousands of yards of export.
