Excavation Contractor in Denver, CO
Urban excavation on Denver's narrow lots — foundation digs, trenching, and grading with real access and neighbor-protection planning.

Building in Denver
Denver excavation is a logistics problem as much as an earthwork problem. On a 25-foot-wide lot with alley access and a neighboring foundation a few feet from the property line, the machine you can physically get in place determines the schedule, and the neighbor's structure determines how the cut has to be made.
We plan those jobs backward from access: what fits down the alley, where spoil stages, whether a street occupancy permit is needed, how trucks turn around, and what protection or monitoring the adjacent structures require. Getting that wrong is what turns a two-day dig into a two-week negotiation.
Below grade, older Denver neighborhoods hold surprises — abandoned coal chutes and cisterns, old clay sewer laterals, unmarked service lines, and fill from previous construction. We locate, expose carefully, and document what we find rather than pushing through it.
Permitting and approvals
- Denver building or grading permits appropriate to the scope of excavation.
- Right-of-way, street occupancy, and container permits for staging in public space.
- Colorado 811 utility locates before every dig.
- Stormwater and erosion control measures where the disturbed area triggers them.
What shapes a Denver project
Narrow lots and alley-only access
Equipment selection, spoil staging, and truck routing all have to be resolved before mobilization. Compact machines and more cycles are often the only workable answer.
Adjacent structures near the cut
Excavating within a few feet of a neighboring foundation can require shoring, benching, or a modified cut sequence, and sometimes documented pre-construction condition surveys.
Unknown buried features
Pre-1940 neighborhoods contain abandoned laterals, cisterns, and construction fill. Careful exposure beats speed here, and unexpected finds get documented and priced transparently.
Right-of-way and street use
Staging equipment, containers, or trucks in the street generally requires a city permit, and parking restrictions need to be arranged in advance on dense blocks.

Denver questions, answered
Can you excavate a basement addition on a narrow Denver lot?
Often yes, with compact equipment and a cut sequence designed around the adjacent structures. The engineering question is how close the excavation comes to a neighboring foundation and whether shoring or benching is required — that gets answered before we dig, not during.
Do I need a street permit for excavation work?
If equipment, spoil, or containers occupy the street or alley right-of-way, generally yes. We handle those applications as part of the project and schedule around the approved dates.
What if you hit something unexpected underground?
In older neighborhoods it happens — abandoned laterals, cisterns, or buried debris. We stop, document what is there with photos, and bring you a clear description of what it changes in scope and cost before continuing.
How do you protect my neighbor's property?
By planning the cut so it does not undermine their foundation, controlling spoil and equipment tracking, keeping access clear, and where the situation warrants it, documenting pre-existing conditions before work starts.
