HOW WE WORK

Precision Trenching and Conduit Work That Keeps the Schedule Moving

We install conduit and concrete-encased duct bank systems for commercial and government builds with a focus on depth accuracy, alignment, and coordination with the electricians and engineers who depend on it, so the underground work supports the schedule instead of holding it up.

Deep Trenching Capability

Subexcavation up to 13 feet for conduit runs, concrete-encased duct bank installation, and complex site conditions.

Accurate Depth & Alignment

Conduit and duct bank runs trenched to plan, so downstream electrical and telecom work lands where the drawings say it should.

Field Coordination

Direct coordination with electrical GCs, engineers, and inspectors to keep conduit installation aligned with the overall build.

Inspection-Ready Work

Trenching, placement, backfill, and compaction executed to spec and ready for inspection without rework or delays.

Common Questions About Commercial Trenching and Conduit Work

Common questions contractors, developers, and electrical GCs ask about trenching and conduit installation.
What's your depth capability for trenching and conduit runs?
Our equipment and expertise handle subexcavation up to 13 feet deep, covering the vast majority of commercial conduit and duct bank requirements. We also manage rock excavation and difficult soil conditions common across Douglas County and the Front Range.
What's your depth capability for trenching and conduit runs?
How do you coordinate with electricians and other trades?
We coordinate directly with your electrical GC, engineers, and project team to sequence trenching and conduit placement with the overall schedule. We handle call-before-you-dig, locate requests, and inspection scheduling so the underground work doesn’t become a bottleneck.
How do you coordinate with electricians and other trades?
We coordinate directly with your electrical GC, engineers, and project team to sequence trenching and conduit placement with the overall schedule. We handle call-before-you-dig, locate requests, and inspection scheduling so the underground work doesn’t become a bottleneck.
Do you handle both dry utility trenching and multi-conduit duct bank runs?
Yes. We handle single conduit runs and full concrete-encased duct bank installation for electrical distribution, along with multi-conduit layouts for telecom, fiber, and data systems across commercial and government projects on the Front Range.
Do you work on government and municipal projects?
Yes. We work on both commercial and government projects, understanding the specification and documentation requirements that come with public work. Our team is experienced with prevailing wage, inspection protocols, and municipal standards.
What happens if you encounter existing utilities during trenching?
We follow strict call-before-you-dig protocols and work with locate services before breaking ground. If we encounter unexpected utilities, we stop work, coordinate with the appropriate parties, and adjust our approach to protect existing infrastructure.
