Industrial Construction at Timberline and Prospect

Door size, yard room and slab thickness decide whether a small-bay industrial building in southeast Fort Collins leases, and we design for all three before anything else. The Timberline and Prospect area is where Fort Collins puts its working buildings: shops, trades, light assembly and storage, within reach of Prospect Road, Timberline Road, Highway 14 and the interstate.

A broker listing describes a newly built 24,000 sq ft industrial building, built in 2025, at the southeast corner of I-25 and Prospect Road, offering suites from 3,000 to 24,000 sq ft, 12 ft by 12 ft and 14 ft by 14 ft overhead doors, and about 0.6 acres of fenced yard with room for about 3.5 more acres. We treat a listing as a sign of what the market is selling, not as a record, but its features match what we hear from owners: doors big enough for a service truck, a yard that can grow, and suites that can be combined or split. We build to that kind of program.

From 3,000 sq ft suites to a full small-bay building

Small-bay users range from one-person trades to light-manufacturing firms with a dozen employees. A single owner might want a warehouse building with a front office and a rear yard, while a developer wants a row of demisable suites that can be leased separately. The two programs share a structure but differ in utilities: separate meters, fire separations between suites and individual restrooms for each tenant.

A pre-engineered metal building often delivers this program economically, with clear spans and a bolted frame that can be extended later. We review the manufacturer's design loads against local criteria, and we detail the walls and doors so they can take the beating that service trucks and forklifts deliver every day.

Slabs, aprons and the yard

In a small-bay building the slab does the most work, and it deserves good detailing: reinforcement matched to the loads, control joints placed at columns and door lines, and edges thickened at overhead doors. We inspect concrete placement and finishing as it happens, which lets us correct a low spot or a joint problem on the day instead of discovering it weeks later.

Yards need their own design. A fenced area with trailers or equipment sees repeated point loads, and the paving or aggregate surface under it must be built to carry them, which is the subject of our stabilized parking lots work. Sidewalks, ramps and accessible routes are built to the standard in site concrete and ADA compliance, and we check slopes before forms are stripped.

Frost, snow, wind and a small-building testing option

Fort Collins building design criteria list a 30 inch frost depth and Seismic Design Category B. They set a minimum ground snow load of 50 psf (ultimate) for Risk Category 1 and 2 buildings, with a roof snow load of at least 43 psf, and wind design refers to the Front Range Gust Map. A shop roof in this area must be designed to the snow load, even when the owner expects to heat the building, because a failed roof does not care about intentions.

The city also requires commercial air leakage testing, with an alternative protocol for small commercial buildings under 5,000 sq ft, and provides a commissioning fact sheet and checklist alongside its 2024 code set. Many suites in this part of town fall under that small-building threshold, so the testing is simpler, but it still has to be scheduled and documented. Access to this area often comes by way of the Mulberry and I-25 interchange, and we check that route when we plan construction deliveries.

Why a small building costs more per square foot

Fixed costs spread over fewer square feet. A building of 10,000 sq ft still needs a utility service, a stormwater plan, a fire line and a permit set, and these cost almost as much as they do for a building twice the size. We list those items separately, as a site utilities package and a site development budget, so an owner can see which costs belong to the lot and which belong to the building.

Listings give a sense of rents: a broker listing for a business park at 2518 Midpoint Drive, a 9,920 sq ft complex built in 1984 with access to Prospect Road, Timberline Road and Highway 14, showed a 2,480 sq ft industrial suite at $13.00 per sq ft NNN. We use numbers like that to test a developer's pro forma, but only as one point among many.

Phasing a spec project and serving tenants who will not wait

A developer building suites for lease usually wants the shell first and finish work as tenants arrive. We build the structure, slab, roof and utilities for the whole building, then finish individual suites to each tenant's plan, sequencing so that early occupants are not disturbed by work next door. Fire separations and shared systems are completed before the first certificate of occupancy.

Owners who serve automotive and EV trades, such as service shops, upfitters and charging installers, tend to want taller doors, floor drains and strong electrical service, and we design accordingly. Another market is the nearby Harmony Road corridor, where users who need more office and less yard can compare space.

Give us the program and the lot

Tell us the suite sizes, the doors you need and the yard you expect to use. We will test the program against the lot and the local criteria, then return a budget and sequence.

Common Questions

What door sizes are typical for small-bay industrial space?

A recent listing in this area describes 12 ft by 12 ft and 14 ft by 14 ft overhead doors, which handle service vans, box trucks and many tradespeople's vehicles. Your tenants may need taller doors for lifts or equipment. We recommend setting door sizes for the tallest likely user, since enlarging an opening after the wall is built is expensive.

What snow load should I expect to design for?

Fort Collins lists a minimum ground snow load of 50 psf (ultimate) for Risk Category 1 and 2 buildings, with a roof snow load of at least 43 psf. Your engineer will apply the criteria to your roof shape and exposure, and drifting near taller structures can add load. We include these numbers in the structural budget from the start.

Does air leakage testing apply to small suites?

The city requires commercial air leakage testing and provides an alternative protocol for small commercial buildings under 5,000 sq ft. That makes testing simpler for small suites, but results still have to be documented. We schedule the test before the finishes hide the envelope and correct any leaks found.

How much yard should I plan for?

The right answer depends on trailers, equipment and vehicle count. A recent listing describes about 0.6 acres of fenced yard with room for about 3.5 more acres, which shows how developers think about growth. We help you choose a yard size that matches your use, and we lay out the parcel so the yard can expand without disturbing the building.

Can we split a building into separate suites later?

Yes, if it is designed for it. That means utilities that can be separated, a roof structure that allows demising walls, and doors and restrooms placed with future suites in mind. The incremental cost at construction time is modest compared with the cost of altering a finished building.
