Colony Construction delivers structural steel for Montana mining, agriculture, and Inland Empire forestry – from Butte and Stillwater hard-rock operations and Rocky Mountain Front cattle and grain facilities to Libby and Deer Lodge sawmills and Bakken-edge midstream construction. Founded in 1985 and responsible for more than 700 completed projects, Colony brings 40+ years of heavy-industrial, cold-climate steel experience to Montana owners. Every frame is engineered to AISC 360-22, welded to AWS D1.1:2020, stamped by licensed US PEs, and executed under federal OSHA and MSHA jurisdiction. Our Alberta and BC portfolio transfers cleanly onto Montana’s Rocky Mountain Front, Hi-Line, and Yellowstone Corridor projects.
Montana Steel Construction Expertise
Montana adopts the IBC through the Department of Labor and Industry (DLI), with state amendments that local AHJs layer on top. Seismic hazard is low to moderate across most of the state – Design Category B or C – climbing to Category D in the southwestern corner near the Yellowstone and Centennial ranges. ASCE 7 ground snow loads govern many Montana buildings: 40 to 70 psf is common across the Hi-Line and eastern plains, climbing to 100+ psf in the Rocky Mountain Front and Absaroka-Beartooth counties. Colony details primary framing to the site-specific ASCE 7 load combination and works with Montana-licensed PEs for DLI-stamped submittals. Federal OSHA has jurisdiction on non-mine work; MSHA Title 30 CFR applies the moment a worker crosses onto an active mine.
Montana’s industrial economy spans hard-rock mining at Stillwater (platinum and palladium) and Continental Pit at Butte (copper), a deep agricultural base across the Hi-Line and Yellowstone Corridor, Inland Empire sawmill work in the Libby, Deer Lodge, and Bitterroot valleys, and Bakken-adjacent oil and gas in eastern Richland and Roosevelt counties. Colony has fly-in mine, SAGD oil and gas, sawmill envelope, and ag-processing projects in our portfolio – all direct pattern matches for the Montana operator base.
What We Build in Montana
- Mining Construction – mills, truck shops, and mantle-rebuild facilities for Stillwater platinum-palladium and Butte copper operations under MSHA Title 30 CFR Parts 56 and 57.
- Agriculture Construction – grain-handling structures, feedlot buildings, and ag-processing envelopes across the Hi-Line, Yellowstone Corridor, and Rocky Mountain Front.
- Forestry Construction – sawmill and planer-mill envelopes for Libby, Deer Lodge, and Bitterroot Valley operators with NFPA 664 dust discipline.
- Oil & Gas Construction – modular process buildings, pipe racks, and maintenance shops for Bakken-edge midstream work in Richland and Roosevelt counties.
- Manufacturing & Warehousing – Billings, Great Falls, and Missoula industrial distribution envelopes.
Regional Challenges We Solve
High Ground Snow Loads in the Rocky Mountain Front
ASCE 7 ground snow loads of 70 to 100+ psf govern many Montana mountain-county structures. Colony details purlins, primary frames, and drift-plus-unbalanced load cases to the site-specific snow demand, with braced-bay layouts and cold-formed framing selections that stay economical at the load level. The discipline transfers directly from our BC interior and Yukon mountain-county portfolio.
Cold-Weather Steel for -30 deg F Service
The Rocky Mountain Front and Hi-Line see design temperatures of -30 deg F and below, pushing CVN notch-toughness specifications on primary steel and winter welding procedures qualified to AWS D1.1. Colony’s Alberta and Yukon cold-weather experience reads directly onto Montana projects north of Billings.
MSHA Part 56 and Part 57 Compliance at Butte and Stillwater
Any construction work inside an active Montana mine runs under MSHA Title 30 CFR, not OSHA. Colony supervisors carry MSHA Part 46 surface and Part 48 underground training, coordinate daily workplace examinations under 56.18002 and 57.18002, and integrate owner-specific orientation before boots hit the ground.
Bakken-Edge Midstream Construction
Eastern Montana’s Bakken-adjacent oil and gas economy runs on modular process buildings, compressor-station enclosures, and maintenance shops under aggressive schedule and API 650 / API 2610 adjacency. Colony’s Kearl Lake, MEG Energy, and Canadian SAGD experience translates directly onto Bakken-edge midstream work from Baker through Plentywood.
Heavy-Haul Logistics Across Montana
Montana’s I-15, I-90, and I-94 corridors are long and lightly serviced. Colony coordinates over-dimensional steel deliveries with Montana DOT permitting, plans escort requirements, and sequences deliveries around the seasonal road restriction cycles that govern Montana secondary highways.
Montana Projects
Newmont Red Chris Mine
Structural steel for process and support facilities at a large copper-gold operation in remote, seismically active, high-snow terrain. The remote-mining scope and cold-weather erection planning read directly onto Stillwater platinum-palladium and Butte copper operations.
West Fraser Quesnel Sawmill
Planer-mill and sawmill envelope with NFPA 664 dust discipline and long clear-spans integrated with process equipment. Directly applicable to Inland Empire Libby, Deer Lodge, and Bitterroot Valley sawmill rebuilds and new mill construction.
MEG Energy Phase 2
SAGD-adjacent oil and gas process facility with modular process buildings, pipe racks, and cold-weather envelope engineered to -40 deg C service. The midstream building-type and cold-climate expertise transfers directly to Bakken-edge Richland and Roosevelt county construction.
Frequently Asked Questions
Which Montana markets does Colony serve – Butte and Stillwater mining, Inland Empire forestry, Bakken-adjacent oil & gas, Rocky Mountain agriculture?
All four. Our focus is heavy-industrial scope – MSHA-compliant mining buildings at Stillwater and Butte, NFPA 664-compliant sawmill envelopes in the Inland Empire, Bakken-edge midstream modules in eastern Montana, and ag-processing envelopes across the Hi-Line and Yellowstone Corridor – rather than general commercial construction.
How does Colony approach Montana snow loads and cold-weather steel for the Rocky Mountain Front?
We design to ASCE 7 site-specific ground snow loads – 40 to 70 psf on the plains, 70 to 100+ psf in mountain counties – with drift-plus-unbalanced load cases and braced-bay layouts that stay economical at the demand level. Design temperatures of -30 deg F and below drive CVN notch-toughness specifications and qualified winter welding procedures.
What Montana Building Code and DLI (Department of Labor and Industry) requirements apply to industrial construction?
Montana DLI administers code adoption, currently built on the IBC with state amendments. Local AHJs (Billings, Missoula, Great Falls, Bozeman, Helena) layer their own amendments on top. Colony tracks adoption cycles and works with each AHJ’s specific amendment package, coordinating with Montana-licensed PEs for state-stamped submittals.
Can Colony serve Bakken midstream and oilfield construction from Montana into western North Dakota?
Yes. The Kearl Lake, MEG Energy, and SAGD portfolio in our record gives us direct pattern-matching experience for Bakken-edge construction on the Montana-North Dakota border. Modular process buildings, compressor-station enclosures, and maintenance shops are a recurring scope – deliverable under single-source engineering, fabrication, and erection.
