Industrial Build-Outs and Plant Expansions in the Denver Metro
An industrial build-out gets sized around the process, so the service, feeders, and branch circuits are set before the first machine lands on the floor.
A build-out starts with load. Connected load, demand factors, and what the process equipment actually pulls at full rate drive the service size, the utility coordination, the main switchboard or switchgear, and the feeder routing to every panel and disconnect. Motor loads carry the largest motor at 125 percent in the calculation, and spare capacity gets built in on purpose, because adding a second service later when a line expands costs far more than upsizing a feeder now.
The rest is layout and coordination with the other trades. Conduit racks go above the process area, stub-ups and floor sleeves get set before the slab pours, and panel locations have to keep the working space required by NEC 110.26 clear of racking, staged pallets, and lift traffic. Equipment locations are checked against submittals so a required disconnect does not end up behind a machine guard, and rough-in, cover, and final inspections are staged with the authority having jurisdiction. 10 Point Services works out of Golden and covers the Denver metro for this kind of work.
What is included in an industrial electrical build-out?
Typically the service entrance and metering, the main switchboard or switchgear, feeders to distribution panels and motor control centers, branch circuits and disconnects for process equipment, the grounding electrode system, area lighting, and the permits and inspections that go with all of it. On a plant expansion the same scope applies to the new area, plus whatever upsizing the existing service needs to carry it.
How is electrical load calculated for a plant expansion?
Start with nameplate full-load amps for every piece of equipment, then apply the demand factors and calculation methods in NEC Article 220, with the largest motor added at 125 percent. Duty cycle matters: a welder or an intermittent press does not count the same as a compressor that runs most of the shift. The result gets compared against the existing service capacity, usually with recorded demand data from the utility or a logger on the main.
Do plant expansions in Colorado require an electrical permit?
New services, feeders, branch circuits, and equipment connections are permitted and inspected work. Colorado adopted the 2023 NEC at the state level, and cities and counties in the metro enforce it through their own building departments with local amendments, so the permitting path depends on which jurisdiction the plant sits in. Inspections are normally staged at underground, rough-in, and final.
