Warehouse Construction in Evanston, Wyoming

Warehouse and distribution construction in Evanston, Wyoming: deep-frost footings, heavy snow-load roofs and wind-exposed truck courts along I-80.

Footings in Evanston go at least 54 inches below finished grade, and 70 inches where an unprotected footing is subject to frost creep. That one line from the city's design load sheet tells an owner more about the cost of a warehouse here than any rate per square foot. We build warehouses and distribution shells in Evanston with the foundation first in mind: deep footings, frost-protected slab edges, and a roof designed for a 40 psf minimum snow load, or 60 psf in basin areas.

The wind numbers deserve attention too. The city's sheet calls for a 100 mph basic wind speed with exposure B in the developed city area and 110 mph with exposure C on the surrounding benches, so a building on a bench lot takes more wind than one in town and needs a stiffer structure. Evanston is bisected by I-80 at 6,749 feet and also served by US 189, Wyoming Highway 89 and Wyoming Highway 150, which gives a freight user a choice of ways in and out.

We read that load sheet before we sketch a floor plan, and we share it with every consultant on the job.

The load sheet and the code office

Evanston's design load sheet is written for use with the current International Building Code. Besides wind and snow, it lists seismic zone D1 for residential and the footing depths already noted. The International Code Council states that Wyoming has no single statewide building code and that local governments adopt and enforce theirs, and design snow, wind and frost values are set locally and vary widely. Laramie County, for example, lists a 32 lb/ft2 ground snow load and a 36 inch frost line depth in its residential table.

For an owner, the lesson is not to borrow numbers. A building drawn for another town's criteria may be under-designed here or over-designed and expensive. We start from Evanston's published sheet, confirm with the city building office, and ask your engineer of record to certify the final design values. That keeps the permit review short and the construction free of late structural changes.

Rail history and a very large data center plan

Evanston began as a Union Pacific divisional point. A machine shop and roundhouse were added in 1871, the Union Pacific Railroad Complex is on the National Register of Historic Places, and Union Tank Car repairs railroad tank cars near it. That industrial history means the town already has trades, yards and shops used to heavy work, and the I-80 interchange gives warehouse tenants a quick link to the highway.

Then there is the data center. Uinta County commissioners unanimously approved Prometheus Hyperscale's 1.25 gigawatt data center on 506 acres of ranchland about 12 miles east of Evanston on the south side of I-80, reported June 19, 2026, with mostly natural gas power and construction to begin within six months of final permitting and take four to five years. Prometheus estimates a $16 billion investment, a judge dismissed a legal challenge on August 17, 2026, the county's permit carries about 30 conditions, and as of August 25, 2026 construction had not begun. We watch it closely, because a project of that scale would bring a sharp increase in demand for supply and staging buildings, and a data center support facility is something we can build.

Foundations and tilt-up in deep frost

Deep frost footings are slow, so we plan them like a project of their own. We excavate, form and place footings in a sequence that lets the next trade start while concrete cures, and we protect the work from freezing until it reaches strength. Backfill and compaction follow the geotechnical report, and we do not backfill against green walls. Tilt-wall panels, which suit the heavy snow loads and the wind, are cast on the slab and set once the concrete reaches strength, a method we use in tilt-wall buildings across Wyoming.

Slab edges need extra attention at this latitude. Insulation at the perimeter and under unheated edge conditions keeps frost from lifting an industrial concrete floor at the walls, and joint layout at the doors prevents cracking where trucks enter. Those details are small on a drawing and large in a ten-year maintenance record.

Working at 6,749 feet

Altitude and cold both affect crews. We schedule heavy lifting for the warm part of the day, keep warm-up areas near the work and plan for short winter daylight. Panels are braced as they are set and tied to the slab before the crane releases them. A wind of the kind the load sheet anticipates would be enough to threaten a loose panel, so lifts stop when gusts rise.

Traffic on I-80 and the nearby highways also shapes the site plan. We locate haul routes, flaggers and staging to keep trucks off the shoulder, and we coordinate delivery windows so concrete trucks do not wait with the drum turning. Visitors to the site sign in and receive a briefing before walking the slab.

What Evanston adds to the price

Evanston's price premium over a lower town comes from four items: deeper footings, a heavier roof structure, winter protection for concrete and a shorter productive season. None of these is a surprise if the load sheet is read at the start. We itemize them so an owner can see what the climate costs and what the building costs.

Some owners reduce the premium by phasing. A first phase with fewer bays, one set of docks and a smaller yard can open sooner and prove the business. We lay out the foundation and utilities so the next phase can attach without tearing out the first. Developers use the same approach to lease space in stages. For a regional comparison, we can price the same shell in Rock Springs or Kemmerer.
