What excavation work covers
Excavation in the Denver metro includes foundation cut, site grading, utility trenches, benching, sloping, and shoring when soils or lot-line conditions require it. Neighboring structures, utilities, and the public right-of-way often drive method. A municipally licensed Denver general contractor coordinates earthwork and licensed specialty trades. Cost is project-specific and depends on depth, soils, and protection of adjacent property.

What buyers should prepare
Proposed depth, distance to lot lines, any soils report, photos of neighboring structures, and whether the dig will touch the alley or street.
FAQ
Common questions
How much does Concrete Flatwork Visit cost in Thornton?
$99 visit fee — credited toward the work.
How do I book?
Press Book next to the job, pick a date and a morning (8–12) or afternoon (12–4) window, and pay in full. We confirm within 24 hours or refund you in full.
Do I need a separate excavation permit in Denver?
Often yes when the cut is over 4 feet deep, close to a lot line, or steeper than 1.5 to 1. Houses may include excavation details with the building permit, with excavation issued before construction.
Who handles excavation permits and licensing?
A municipally licensed Denver general contractor coordinates the project and licensed specialty trades. Colorado has no statewide general contractor license.
What is SUDP doing on a dig?
DOTI reviews sewer, storm grading, floodplain, groundwater, and ROW impacts for excavations. It is a separate review that typically runs with the building package.
When is shoring required?
When slopes cannot be laid back to the allowed ratio, when the cut is near a lot line or structure, or when the soils report requires it. Design professionals seal those packages.
What information helps define scope?
Depth, lot-line clearance, floodplain status, existing utilities, and city or county.
