# Commercial Excavation in Denver

Commercial excavation in Denver handles larger utility lines, fire lines, storm systems, and sites with tighter access, inspection, and schedule requirements. Denver Sewer and Water coordinates with property managers, general contractors, and municipalities to keep the project moving.

- Commercial sewer, water, and fire line excavation.
- Storm drain and catch basin work.
- Right-of-way and traffic control permitting.
- Coordination with GCs and property managers.
- Asphalt and concrete restoration to spec.

## When Does a Commercial Site Need Excavation?

Commercial sites need excavation when the utility infrastructure fails or has to be upgraded. That can be a sewer main backing up, a water service leak under a parking lot, a fire line that fails acceptance testing, or a storm system that no longer handles runoff.

The stakes are higher on commercial jobs because the line sizes are larger, the surfaces are more expensive to restore, and the schedule affects tenants or operations.

- Sewer and water service repair under parking lots or driveways.
- Fire line installation, repair, and hydrant connections.
- Storm drain replacement and catch basin repair.
- Service upsizing for tenant improvements or additions.
- New construction utility rough-ins and taps.

## Repair in Place or Full Replacement?

On commercial lines, a spot repair can make sense when the failure is isolated and the rest of the line is in good condition. Full replacement makes sense when the line is undersized, deteriorated, or has multiple failure points.

We expose the line and assess the condition before recommending the scope. Commercial decisions have to balance repair cost against the cost of doing the job twice.

## How an Excavation Job Runs

1. **Camera and Locate** We scope the line, grade it, and mark depth and defect locations. Utility locates are requested and verified on site before any equipment moves.
2. **Permits and Traffic Control** Sanitary review, right-of-way permits, and a traffic control plan where the street requires one. We carry these rather than handing them to the owner.
3. **Site Protection** Access route planned, surfaces protected, spoils staged, and tree protection observed where the canopy or root zone is regulated.
4. **Careful Exposure** Around known crossings we vacuum excavate rather than dig blind. Paint on grass is an approximation, not a guarantee.
5. **Excavate, Shore, and Repair** The trench is opened and shored to depth, the pipe is replaced or the connection is made, and the work is inspected before it is covered.
6. **Backfill and Restoration** Compacted in lifts to the spec for the surface above, then the surface is restored to what was cut, including concrete, asphalt, and landscape.

## What Drives Commercial Excavation Cost?

Commercial excavation costs are driven by line size, depth, surface restoration, and the schedule constraints of the site. Asphalt and concrete restoration on parking lots and driveways is a larger line item than turf.

We work with the property manager or general contractor to phase the work and minimize disruption to operations.

- Line size and depth.
- Surface type: asphalt, concrete, paver, or landscape.
- Traffic control and right-of-way requirements.
- Schedule constraints and phasing needs.
- Inspection and acceptance testing requirements.

## Frequently asked questions

**Do you locate utilities before excavating?**

Always. Locates are requested and then verified on site. Around known crossings we expose utilities with vacuum excavation rather than digging blind. Paint on grass is an approximation of horizontal position, not a guarantee of depth.

**How much of the property gets torn up?**

It depends on the method the pipe supports. A full open cut replacement needs a trench the length of the run. A trenchless repair needs only access pits. We show the footprint on the site before the work starts.

**Do you restore the surface after excavation?**

Yes, to the specification for what was cut. Concrete is replaced with concrete, asphalt with asphalt, and turf is backfilled and compacted so the trench does not settle into a rut.

**Can you work around business hours?**

Yes. We coordinate with property managers to schedule work during off-hours, weekends, or phased shutdowns so the business can keep operating.

**Do you handle fire line excavation and testing?**

Yes. Fire line excavation includes the tap, the line run, and coordination with the fire marshal or authority having jurisdiction for acceptance testing.
