"Trail Mountain ran our data center expansion like a Tier III is supposed to run — clean drawings, paralleled the gear without a single false transfer, and finished seven weeks ahead of schedule. They were the only contractor on site whose punch list we accepted on first walk."

Overview
An in-house licensed electrical engineering team enables single-source design-build, EPC, and progressive delivery. We compress the schedule by overlapping design with procurement and field work.
Our preconstruction and engineering team includes Utah-licensed PEs, NABCEP-certified solar designers, and BIM-VDC modelers. We deliver design-build under AIA A141, ConsensusDocs 410, and EPC contracts, and we routinely overlap 30%-design release with long-lead procurement so owners shave weeks off the critical path.
Inside the team we run SKM and ETAP for power-system studies, Helioscope and PVsyst for solar yield, Revit/Navisworks for clash detection, and Bluebeam for issued-for-construction sets. Every project gets a real RACI, a real schedule, and a real risk register — owners and GCs get transparency, not promises.
Where the project benefits from progressive design-build, we offer open-book preconstruction with a target-value design approach. Owners see line-item budget, crew loading, and material escalation assumptions, and we lock GMP only when scope, schedule, and price all line up.
Capabilities
What we self-perform under this discipline.
Our crews self-perform every capability listed below. We sub specialty trades only when the scope demands it, and we manage them under our prime contract.
- Design-build under AIA A141 and ConsensusDocs 410
- EPC contracting for solar, BESS, and substations
- Progressive design-build with target-value design
- Coordination, short-circuit, and arc-flash studies (SKM/ETAP)
- Solar production modeling (Helioscope, PVsyst)
- Revit/Navisworks BIM-VDC coordination
- Long-lead procurement strategy
- Constructability and value-engineering reviews
- Open-book preconstruction with line-item transparency
Frequently asked
Common questions about this service.
- Yes. We have Utah-licensed PEs on staff for power, lighting, and PV design. For Idaho, Wyoming, and Nevada projects, we partner with reciprocal-licensed PEs and stamp accordingly.
- AIA A141 design-build, ConsensusDocs 410 design-build, EPC, progressive design-build with GMP, and lump-sum spec-bid. We're also CMAR-qualified in Utah and Idaho.
- Yes. Our design-build approach typically saves 20–40% off a comparable design-bid-build schedule by overlapping engineering with long-lead procurement and field work. The savings depend on owner decision speed.
What clients say
Owners and general contractors keep coming back.
Roughly 70% of our annual commercial volume is repeat business with the same owners and GCs. Below are recent quotes, all attributed and verifiable.
"We've used Trail Mountain on three hospital pavilions now. They self-perform the work, they understand NFPA 99, and they bring documentation that makes our QA team's job easier — not harder. They're our go-to electrical contractor for healthcare in Utah."
"Our 20,400 sq ft Promontory home had a Lutron HomeWorks panel with 340 channels, hybrid Powerwall and Kohler standby, snowmelt, architectural lighting — Trail Mountain commissioned the whole house in a single pass with zero punch items. That doesn't happen."
"We selected Trail Mountain for the I-15 NEVI corridor because they could actually deliver eleven sites in nine months. Every site passed FHWA reimbursement on the first audit, and uptime has held above 99% since commissioning."
"Our cleanroom expansion happened inside a fully operational biotech facility. Trail Mountain coordinated through QA, met our IQ/OQ timeline with zero rework, and our validation team accepted their documentation on first review — which never happens with electrical."
"I've worked with maybe a dozen solar contractors across Utah. Trail Mountain is the only one I'd hand a 12MW ground-mount and an 8MWh BESS to without sleepless nights. They commissioned three months early. We saved $1.8M in MACRS and ITC."
