Industrial and Data Center Site Work in Evanston, Wyoming

Footings in Evanston go at least 54 inches below finished grade, and 70 inches when they are unprotected and subject to frost creep, so a building here starts deeper than most contractors expect. We build industrial shells, equipment yards and heavy site civil in Uinta County with those numbers in the first estimate, not discovered at the first excavation.

The city's design load sheet, written for use with the current International Building Code, calls for 100 mph basic wind speed in the developed city with exposure B and 110 mph with exposure C on the surrounding benches. It requires a 40 psf minimum snow load, 60 psf in basin areas, and seismic zone D1 for residential. A pre-engineered building ordered from the wrong table will be rejected, and one that is merely oversized will cost money. We pull the right values before the order goes in.

Evanston is also where a very large energy project has been proposed. We treat it as context, not as a promise, and plan for it in ways that serve any owner building nearby, including operators in data centers who are weighing the same corridor.

Design Loads, Frost and Permit Review

Design snow, wind and frost values are set locally in Wyoming, and Evanston's are among the demanding ones. Wyoming has no single statewide code, and the state adopted the 2024 International Codes on June 28, 2024, with localities adopting on their own timelines. Check the city load sheet first, then ask the building official which edition and amendments apply to your parcel.

Frost depth drives more than footings. Slabs-on-grade need edge insulation or deepened edges, utility lines need burial depth below the frost line, and doors and aprons need details that do not heave. We design the whole building envelope to the 54 inch rule so the loading dock does not sit on a frozen mound by February.

A Rail Town on I-80 With a Large Proposal Nearby

Evanston is the seat of Uinta County at 6,749 feet. I-80 bisects it, and US 189, Wyoming Highway 89 and Wyoming Highway 150 also serve it. It began as a Union Pacific divisional point, with a machine shop and roundhouse added in 1871, and a railroad tank car repair operation still works near the old complex. Hospitals and a state psychiatric facility are among the major employers.

The large proposal is a 1.25 gigawatt data center on 506 acres of ranchland about 12 miles east of Evanston on the south side of I-80. Uinta County commissioners unanimously approved it, as reported June 19, 2026. Power would come mostly from natural gas, and construction would begin within six months of final permitting and take four to five years. A developer estimate of $16 billion was reported, a judge dismissed a legal challenge on August 17, 2026, the county permit carries about 30 conditions, and as of August 25, 2026 construction had not begun.

Building Next to a Project of That Size

An energy project on that scale would reshape the local market in three ways. It would draw trades, pushing up wages and lengthening bid lead times. It would load the highway and the interchanges with heavy trucks during construction. And it would put pressure on housing, lodging and services in Evanston. Owners who plan to build in town should assume those pressures and commit early to trades and materials.

It would also create opportunities for suppliers and service companies who need shops, yards and warehouses near the interstate. We build those: maintenance shops and service bays for equipment fleets, and truck courts and trailer yards for carriers who haul to and from the campus.

Heavy Site Civil in Cold Ground

Large power and data campuses are mostly civil work before they are buildings. Site clearing and mass grading prepares ranchland for roads, pads and drainage. Stormwater detention and drainage is sized for snowmelt and storm events, with outlets planned so they do not freeze shut. We build the temporary roads, the permanent roads and the utility corridors in sequence so the next trade finds them ready.

For data center work specifically, we build the support structures: equipment pads, generator yards, fuel storage containment and the underground electrical duct banks that tie them together. Our data center construction approach starts with power and cooling requirements and works back to the structure.

Wind, Cold and Highway Exposure

Evanston's weather can shut a site down in an afternoon. Wind passes crane limits quickly, and ice on haul roads changes stopping distances for loaded trucks. We train crews to stop work on wind thresholds, treat ice as a hazard and keep warming areas stocked. Daily toolbox talks cover the weather forecast as well as the work.

Trucks entering and leaving I-80 from a work site need traffic control, deceleration lanes where permitted and clear signage. We coordinate with the highway department on access permits early, because those approvals can take longer than the work itself. Visitors get a safety orientation at the gate before they enter active zones. Along the same corridor we also build in Kemmerer and Rock Springs.

Common Questions

How deep do footings have to be in Evanston?

Evanston's design load sheet requires footings at least 54 inches below finished grade, and 70 inches for unprotected footings subject to frost creep. Those are minimums from the city's published sheet, and your engineer may require more. We build to the sheet and verify the current version with the building official before we pour.

What snow load should a pre-engineered building be designed for?

The city sheet lists a 40 psf minimum snow load, with 60 psf in basin areas. Wind is 100 mph with exposure B in the developed city and 110 mph with exposure C on the surrounding benches. Give the metal building supplier those numbers in writing, and confirm them with the building official.

Is the proposed data center near Evanston approved and under construction?

County commissioners unanimously approved it, as reported June 19, 2026. A judge dismissed a legal challenge on August 17, 2026, and the county permit carries about 30 conditions. As of August 25, 2026 construction had not begun. We watch the status as a market signal and advise owners to plan for either outcome.

How will a large campus affect local contractors and suppliers?

It would raise demand for trades, trucking, lodging and materials. Prices and lead times for concrete, steel and electrical gear could rise. Owners with projects planned in the next few years should lock in subcontractors and orders early, and build schedule float for tighter trade availability.

What does Evanston winter do to concrete work?

Winters are long and cold. We use heated enclosures, insulated blankets and accelerated mixes to place concrete in cold weather, and we protect the slab until it reaches strength. Each of those adds cost and time, so we show them as line items. For a start in late fall, we budget for them from day one.
