Commercial New Construction Electrical in Denver
Ground-up commercial electrical, from the temporary power pole through final trim and energized gear.
A ground-up package starts long before rough-in. Utility coordination, the service application, and temporary power get handled early, because the transformer location and the point of service drive site work that cannot be undone later. Underground conduit, feeder stub-ups, and site lighting bases go in ahead of the slab and the paving, on the concrete crew's schedule. Gear submittals go out at award, since switchboards and transformers are usually the longest lead items on the job.
Rough-in follows framing and ceiling coordination. Conduit above a hard lid has to route around duct and drain lines that get first claim on the space, so the layout is settled on paper before pipe goes up. Wall rough lands ahead of drywall, device and fixture trim comes after finishes, then gear energization, testing, and punch. The estimator is the master electrician who runs the job, so the GC is talking to the same person from bid through closeout.
When does the electrical contractor need to be on site for a new commercial build?
Before dirt work, not at framing. Temporary power, the utility service application, and underground conduit all land ahead of the slab, and long-lead gear has to be ordered at award to hit an energization date.
What are the long lead items in a commercial electrical package?
Switchboards, panelboards, dry-type transformers, and utility metering gear. Submittal review and manufacturing time on distribution equipment usually set the critical path, which is why the package gets bought out and released before the building is out of the ground.
How does electrical rough-in coordinate with the other trades above the ceiling?
Gravity systems win the space first: drain lines and large duct get routed, then conduit works around them. On jobs with tight plenums this is settled on coordination drawings before anyone hangs pipe, because moving a rack of conduit after the fact costs days.
