Forty-eight inches is how deep footings go in Eagle County where frost applies, and the county writes it into its own amendment of the building code. That one line shapes the foundation budget on every steel building we quote here. We erect pre-engineered metal buildings for contractor yards, fleet and transit shops, storage and light commercial owners, and we state the load package and the lead time up front.
Eagle County's Building Resolution, amended January 21, 2025, adopts the 2021 International Building Code with Appendices C, E, I and J, plus the 2021 IRC. Fire codes are amended and adopted by Vail Fire and Emergency Services and other fire districts. So two offices can have a say on one building: the county for structure, and the fire district for fire. We bring both into the plan early.
Why mountain-resort building runs through steel
Eagle County Regional Airport has a 9,000 by 150 foot runway, 4 airlines and 6 gates, and recorded 289,867 enplanements in 2024. Air traffic of that size brings charter operators, hangar tenants and the service businesses that follow. For a general aviation owner, a steel hangar with a tall insulated door is the usual answer, and our aircraft hangar scope shows how we price it.
The resort economy runs on support buildings that guests never see: equipment shops, laundry and linen operations, delivery depots, fleet barns, snow-removal storage. Those are plain, wide, high-bay boxes, and steel is the cheapest way to enclose them. Owners in fleet and vehicle operations usually lead the list.
Those buildings share a pattern. Doors tall enough for a plow truck or a shuttle bus. A floor that drains. A wash bay at one end and a parts room at the other. Because the shape repeats, we can price them tightly per square foot, and we can add a second identical bay later for far less than the first one cost. Tell us the vehicle mix and we will draw the bay.
Snow map, ASCE 7 and defensible space
Eagle County amends IBC 1809.5 to require footings subject to frost to be at least 48 inches deep, and replaces IBC 1608.2 so snow loads come from the 2016 Colorado Ground Snow Map or Colorado Design Snow Loads, using the more restrictive of that map and ASCE 7. We apply the rule by running both and writing the higher number on the quote. If a parcel sits in a part of the map with a steep gradient, small changes in location can move the load, so we use the exact address.
Eagle County wildfire regulations apply to all new construction in unincorporated areas, assign each project a low, moderate, high or extreme hazard rating, and require defensible space and ignition resistant construction in moderate, high and extreme zones. Metal roofs and walls help. Vents, eaves, openings and attachments still need review. We ask for the hazard rating at kickoff and design the details to it.
Shops, fleet buildings and storage
A typical Eagle County order is a heated vehicle bay with floor drains and a mezzanine, a cold storage barn, or a row of storage units. We offer liner panels and trim for interior walls that take impact, and we plan overhead door sizes to the tallest vehicle with room to spare.
Fleet and logistics operators also ask about truck terminals and cross-docks, where doors line one or two walls and the slab and apron take heavy loads. We detail the apron and the dock edges alongside the building, because the concrete usually costs as much as the steel.
Insulation is the other choice that changes the bill. A heated bay wants an insulated panel or liner and batt; a cold storage barn wants none. Snow retention over entries is a safety item we raise on every public-facing door, and we price it as an add so you can decide.
Vail Pass and the I-70 grade
Vail Pass (10,662 feet) carries I-70 and formerly U.S. 6 between Vail and Copper Mountain, with a maximum 7% grade and frequent weather related hazardous driving conditions. Trucks from the east climb it, and trucks from the west work the canyons. Either way, a delivery here is slower than on flat ground.
We handle that by splitting shipments, scheduling in good weather windows and keeping the erection start flexible. Foundations go in during the open season. Steel arrives in the next window. We dry in the roof before heavy snow. When a date is firm, tell us at quote and we will say if it can be met. We name the lead time in writing and update it if the fabricator moves.
Footings, snow and fire details
Deep frost footings, a high snow number and wildfire details raise cost compared with a lowland building. We show each as a separate line so you can compare. Steel tonnage follows snow load and span. The roof system is another choice, and a rigid frame erection price includes the crane, crew and bolting, so you can see labor against material.
Ask for the shell price per square foot and a total with finishes. Then look at the neighboring markets. Summit County and Glenwood Springs use different numbers, so a bid from one cannot be copied to the other.
Get an Eagle County steel building price
Send us the parcel, the footprint and the use. We will check the county snow source, the frost depth and the wildfire rating, then come back with a written load package, a lead time and a dollars-per-square-foot range.

Common Questions
The county replaces IBC 1608.2 so snow loads come from the 2016 Colorado Ground Snow Map or Colorado Design Snow Loads, using the more restrictive of that map and ASCE 7. We check both for your address and design to the higher number.
Eagle County amends IBC 1809.5 to require footings subject to frost to be at least 48 inches deep. We use that depth in the foundation design and price it as its own line.
Yes in unincorporated areas. Each project gets a low, moderate, high or extreme hazard rating, and moderate, high and extreme zones require defensible space and ignition resistant construction. Metal helps, but vents, eaves and openings still matter.
Fire codes are amended and adopted by Vail Fire and Emergency Services and other fire districts, so the answer depends on the parcel. We identify the district at kickoff and copy them on the drawings.
Possibly, with a lease or site rights. Eagle County Regional Airport has a 9,000 by 150 foot runway and 6 gates, so airside work follows airport rules. We build the steel and door package once those rights are in hand.
