Electrical Subcontractor for General Contractors
Send us the drawings and the schedule.
ThreeCo subcontracts for general contractors on commercial projects: new construction, tenant finish and renovation. If you are a GC bidding work and need an electrical sub, send us the drawings and the schedule.
What a GC wants from an electrical sub is short: a bid that matches the drawings, a crew that shows up when the schedule says, rough-in that passes inspection the first time, and a straight answer when something on the drawings does not work. That is the job.
What we take on for GCs
- Full electrical packages on new commercial construction: power distribution, wiring, lighting, testing and commissioning.
- Tenant finish and build-out inside existing shells.
- Renovations, including the demolition and make-safe of existing electrical work.
- Lighting and controls packages, including LED and exterior lighting.
- Renewable integration when solar is part of the project.
How we bid
Send the drawings, the specs and the bid date, and we bid the electrical scope they show. Drawings that are unclear or conflict with each other are cheaper to settle in a question before bid day than in a change order after it, so that is when we ask.
Our CEO, Bob DeFries, whose background is in electrical engineering and architectural design, is useful early: coordination questions about distribution and lighting are easier to settle before the walls go up.
What helps an electrical bid come back right
- The electrical sheets and the fixture schedule, plus the architectural set so we can see ceilings and finishes.
- Cut sheets for owner-furnished equipment — kitchen lines, machinery, signage — since each one sets a circuit size.
- Where the utility service will land and who is applying for it; new services carry their own lead time with the utility.
- The schedule, including any phases or areas that have to open first.
- Alternates you want priced separately, so the base bid stays comparable with the others you are getting.
On site
Jason Strange, our COO and Master Electrician, is on staff and signs off on every job ThreeCo runs. On a GC's site that means the electrical rough-in is checked before it is inspected, and the inspector deals with a contractor who knows what will be asked. We coordinate with the other trades on the schedule — rough-in before insulation and drywall, trim-out after paint — and tell the superintendent early when something is going to slip, rather than on the day.
You hear from the person running the work. Real timelines, real numbers and a call when conditions change.
What affects an electrical bid
The scope on the drawings, obviously; then the distribution equipment and its lead time, the fixture package, the schedule and how much of it is compressed, site access and the phase of construction we join at. Long-lead equipment — switchgear, panels, transformers — can set the schedule on its own, so we flag lead times in the bid.
Permits and inspection
The electrical permit is pulled by the electrical contractor doing the work, and the rough-in and final electrical inspections are scheduled around the GC's schedule. Commissioning and testing of every system happens before we hand it over.
