Colony Construction delivers structural steel across the Mountain West – Montana, Idaho, Wyoming, Colorado, Utah, and Nevada – for clients running multi-state portfolios in mining, energy, data centers, ski-resort infrastructure, and Tier-1 manufacturing. Founded in 1985 and responsible for more than 700 completed projects, Colony brings 40+ years of Pacific Northwest and western-Canadian heavy-industrial experience to Mountain West owners. Every frame is engineered to AISC 360-22 and AISC 341 seismic provisions where Wasatch Fault or Walker Lane seismicity requires, welded to AWS D1.1:2020, stamped by state-licensed US PEs, and executed under federal OSHA (MT, ID, WY, CO) or state-plan OSHA (UT, NV) and MSHA jurisdiction. This page gives clients running a Mountain West portfolio a single Colony landing page; state-specific detail lives on the individual state pages linked below.
Mountain West Steel Construction Expertise
The Mountain West is a six-state region that behaves like one industrial market in some sectors (hard-rock mining, ski-resort infrastructure, hyperscale data centers) and six distinct markets in others (state-by-state code adoption, state-plan vs. federal OSHA, AHJ permit practice). Colony delivers to the region’s shared industrial scope while respecting each state’s regulatory framework. Snow loads range from 30 psf on the eastern Wyoming plains and Hi-Line Montana to 150+ psf at Alta, Aspen, Telluride, and Crested Butte; seismic hazard ranges from Category B across eastern Wyoming and Montana to Category D along the Wasatch Front and Walker Lane. Our engineers design to site-specific ASCE 7 load combinations and work with state-licensed PEs in each jurisdiction for stamped submittals.
Mountain West industrial construction runs on four durable cross-state scopes. Hard-rock mining – Nevada gold (Carlin Trend), Utah copper (Kennecott), Colorado molybdenum (Climax, Henderson), Montana copper (Butte, Stillwater platinum-palladium), Wyoming trona and surface coal, and Idaho Silver Valley lead-silver – runs under MSHA Title 30 CFR region-wide. Energy spans Wyoming Powder River and Green River oil and gas, Montana Bakken-edge midstream, and Colorado DJ Basin construction. Data centers are increasingly regional, with Utah Silicon Slopes, Nevada Reno-Sparks, Colorado Front Range, and Idaho Treasure Valley hyperscale clusters. And ski-resort infrastructure – Vail, Aspen, Telluride, Park City, Alta, Snowbird, Deer Valley, Big Sky, Jackson Hole, Steamboat – drives AESS-quality day-lodge, base-station, and lift-support construction. Colony has direct pattern-matching experience for all four.
What We Build Across the Mountain West
- Mining Construction – mills, truck shops, crusher houses, and mantle-rebuild facilities for operators across the Carlin Trend, Kennecott Bingham Canyon, Climax-Henderson, Butte-Stillwater, Wyoming trona, and Silver Valley districts under MSHA Title 30 CFR.
- Oil & Gas Construction – modular process buildings, compressor-station enclosures, and pipe racks across the Powder River Basin, Green River Basin, DJ Basin, and Bakken-edge Montana.
- Data Center Construction – hyperscale shells and colocation buildings in the Silicon Slopes (UT), Reno-Sparks (NV), Front Range (CO), and Treasure Valley (ID) corridors to Uptime Institute Tier III and Tier IV standards.
- Sports & Recreation Construction – AESS day lodges, base-station buildings, and lift-support structures for Colorado, Utah, Montana, and Wyoming resort operators.
- Manufacturing & Warehousing – Tier-1 supplier facilities in the TRIC (NV), Wasatch Front (UT), Front Range (CO), and Treasure Valley (ID) corridors.
Regional Challenges We Solve
Multi-State AHJ Coordination on Portfolio Programs
Mountain West operators running multi-state portfolios face six different code-adoption realities. Utah and Colorado adopt the IBC cleanly through state agencies. Nevada and Wyoming have no statewide code – each county and municipality runs its own cycle. Montana adopts through DLI with local amendments. Idaho adopts through DBS. Colony maintains AHJ practice maps for each jurisdiction and works with state-licensed PEs in each state for stamped submittals, allowing a single integrated delivery team to serve a cross-state portfolio.
Snow Load Range – 30 psf Hi-Line to 150+ psf Alta
ASCE 7 ground snow loads across the Mountain West span a 5x range. Colony designs each structure to the site-specific demand – 30 to 70 psf on the plains and in the Hi-Line; 90 to 100 psf in the Panhandle, Absaroka, and Wind River ranges; 150+ psf at Alta, Snowbird, Aspen, Vail, Telluride, and Crested Butte. Unbalanced-snow, drift-load, and sliding-snow cases are worked into primary-frame and purlin sizing at the load level required.
Seismic Range – Category B to D Across Six States
Seismic hazard ranges from Category B across eastern Wyoming and Montana to Category D along the Wasatch Front (Utah) and Walker Lane (western Nevada). Colony applies AISC 341 seismic provisions with prequalified moment-frame connections under AISC 358 and drift-limit-checked envelope attachments where SDC D demand requires – and keeps the detailing economical where lower-category demand allows.
MSHA Region-Wide for Mining
Every active mine in the Mountain West runs under MSHA Title 30 CFR Parts 56 (surface) or 57 (underground). Colony supervisors carry MSHA Part 46 and Part 48 training and coordinate daily workplace examinations, owner-specific orientation, and ground-control documentation across all six states. The MSHA framework is consistent region-wide – only the owner-specific safety program varies.
Cross-State Logistics – Rail, Truck, and Mountain Passes
Mountain West construction often requires over-dimensional steel crossing multiple state lines via I-15, I-25, I-70, I-80, I-84, and I-90. Colony coordinates multi-state DOT permitting, plans escort requirements, and sequences deliveries around seasonal road restrictions on I-70 Vail Pass, I-80 Donner, and Rocky Mountain passes. Our logistics team has decades of experience shipping into BC interior, Yukon, and Alberta – the Mountain West is an adjacent variation on a well-practiced discipline.

Frequently Asked Questions
Which Mountain West states does Colony serve – Montana, Idaho, Wyoming, Colorado, Utah, Nevada?
All six. We deliver integrated cross-state programs for operators running regional portfolios in mining, energy, data centers, and ski-resort infrastructure, while working with each state’s specific code adoption, AHJ practice, and OSHA framework. State-specific project portfolios and FAQs live on the individual state pages above.
How does Colony handle the Mountain West’s range of snow loads (70 psf Hi-Line to 150+ psf Alta / Aspen / Telluride)?
We design to ASCE 7 site-specific ground snow load, with unbalanced-snow, drift-load, and sliding-snow cases worked into primary-frame and purlin sizing. At the 150+ psf range, braced-bay layouts and connection selections shift to keep the building economical at Alpine-zone loading. The same discipline applies across all six states, scaled to the site-specific demand.
How does Colony coordinate permitting across multiple Mountain West AHJs on portfolio-scale programs?
Colony maintains AHJ practice maps for each jurisdiction across all six states and works with state-licensed PEs in each state for stamped submittals. A single integrated delivery team can serve a cross-state portfolio – one owner-facing point of contact coordinating with six state-specific engineering and permitting tracks. This matters for mining operators with sites across multiple states and for ski-resort groups and data-center developers running multi-state programs.
What is Colony’s cross-state logistics approach for Mountain West mining, data-center, and ski-resort clients?
We coordinate over-dimensional steel deliveries with multi-state DOT permitting, plan escort requirements, and sequence deliveries around seasonal restrictions on I-70 Vail Pass, I-80 Donner, and other Rocky Mountain passes. Our logistics team carries decades of experience shipping into BC interior, Yukon, and Alberta – the Mountain West cross-state environment is an adjacent variation on a well-practiced discipline.
