Rockslides closed Interstate 70 in Glenwood Canyon in February 2016 and again in July 2021, and any shop that depends on a parts truck from the east learned what that means. A maintenance shop on the Western Slope or in an energy corridor is the building that keeps a plant, a fleet or a field operation running when supply is a day away. It needs to hold stock, repair what breaks and work through winter, and its design should assume the parts will not arrive tomorrow.
We build maintenance shops and service bays for plants, utilities, energy operators, contractors and public works. The type ranges from a single-bay metal building with a bridge crane to a multi-bay machine and weld shop with a tool crib, parts room, wash bay and office. Whichever size, the building has to handle the work done in it: heavy lifts, hot work, solvents, compressed air and long hours with the doors open.
This page covers industrial and equipment shops. Where the user's main need is vehicles, our automotive and fleet facilities work covers lifts, pits, charging and exhaust. The two share ventilation and drainage principles, but the loads and layouts differ.
Hot work, fumes and fire
The hazards in a maintenance shop are predictable and controllable. Welding and cutting produce fumes that need source capture at fixed stations and general ventilation with makeup air heated in winter. Grinding and machining create particulate and sparks, so the layout separates them from storage of flammables. Paint, solvent and parts-washing areas need their own exhaust, spill containment and appropriate electrical classification. We design these as systems, not as add-ons after the bays are laid out.
Fire protection follows the contents. Shops store lubricants, gases and combustible materials, and sprinkler design reflects the commodity. Gas cylinders get a dedicated storage area with restraints, and flammable cabinets are located away from egress. Fire doors, extinguisher locations and egress paths are laid out with the fire marshal before drawings are final, and the shop's hot-work permit procedure is built into the layout by locating welding bays where fire watch can be maintained.
Bays, cranes and support rooms
The base scope includes the building, slab, bay doors, lighting, power distribution, compressed air and ventilation. Bridge cranes and jib cranes extend the work: runway beams and crane columns are designed with the crane vendor, and we coordinate them with the structure; the related details are in our crane-ready building work. Support rooms include a tool crib, a parts room with shelving and a counter, a break room, a restroom with showers where work is dirty and an office for planners and supervisors.
Floors take abuse, so we specify them for point loads, impact and chemical exposure. Slab thickness and reinforcing are sized for jacks, stands and heavy parts, and slab surfaces may include hardener or sealer. Radiant heat in the slab is a good fit for shops with large doors, because it warms people and equipment at floor level while doors are open. Drains, sumps and oil separators are located at wash and fluid-change areas.
Building for remote and mountain sites
Remote shops are built around logistics. We plan deliveries for the access road, bring in materials on a schedule that accounts for weather and closures, and inventory what arrives. A pre-engineered shell often makes sense for these sites because the components ship as a package and erect quickly; the structural approach is described in metal building construction. We locate fuel, water and power early, and arrange temporary heat so winter concrete work can proceed.
Glenwood Canyon carries I-70 for 12.5 miles near Glenwood Springs, and the closures there show how a single corridor can interrupt supply to the Western Slope. We carry spare critical items, such as door operators and heater controls, as part of the turnover so the owner's first failure does not require a mountain-pass delivery. We also locate shop doors and yards to take advantage of snow management: leeward sides for entries, snow storage areas away from egress and roof slopes that do not shed onto doors.
Loads, codes and elevation
Code criteria vary by location and elevation. Garfield County's commercial requirements, for instance, call for a 40 psf roof snow load up to 7,000 feet elevation, which covers Rifle, and a 36 inch frost depth up to 8,000 feet, and the county lists the 2015 International Building Code with the 2018 IECC for unincorporated commercial projects, updated July 1, 2023. A shop on a ridge above Rifle will have a heavier snow load than one in town. We confirm the criteria with the building department at the pre-application stage and check them against the owner's elevation.
Rifle's economy has cycled through booms and busts tied to the fossil fuel industry, after earlier growth as a ranching center and railroad commercial hub. For a shop owner, that history means demand can change fast, so buildings should be adaptable. We build with generous clear heights, standard bay widths and utilities that serve a new user without major changes. See our work in Rifle and Glenwood Springs for the regional context.
Who uses these shops
Energy and utility operators use maintenance shops to service compressors, pumps, switchgear and field equipment. Our work for utilities and power buyers covers storage for spares, heavy-lift areas and secure yards. Heavy industry uses shops for mill maintenance, fabrication and rebuild work, and our metals and heavy industry experience extends to crane capacity, heat and noise control.
Municipal and county public works departments use shops for road and equipment maintenance, and contractors use them for fabrication and storage. In all cases, we review the actual work, equipment list and staff size before drawing bays, because a shop sized for last year's fleet is cramped by next year's.
Plan for the day the part does not arrive
Tell us the work the shop does, the heaviest lift and the site elevation. We will return a bay layout, a structural approach and a schedule that accounts for access and weather.
Common Questions
What crane capacity should the shop have?
Size it for the heaviest component you lift, plus a margin, and consider the next equipment generation. The crane vendor supplies reactions that the building structure must carry. Upgrading a crane later is expensive, so we ask for the equipment list and design runway beams with spare capacity when budget allows.
How do we handle welding fumes?
Use fixed-station fume extraction where possible and general ventilation for the rest, with makeup air heated in winter. Fume capture works best near the source. We lay out welding stations so extraction arms reach the work and so fire watch is possible.
Is in-slab heat worth it?
In shops with frequent door openings, it often is. Radiant slab heat warms floor-level work and recovers quickly after doors close. It also complements unit heaters. The slab design must account for the heating loops, so the choice is made before the pour.
How do snow loads affect the building?
Snow load sets the roof structure, and it varies by county and elevation. In Garfield County, for example, the requirement rises with elevation. We use the criteria published by the building department for the parcel.
Can you build a shop in a remote location?
Yes. We plan logistics, temporary utilities and winter work, and we phase deliveries to match site conditions. We also provide a spare-parts list for critical equipment as part of turnover.
