Rail-served sites from 5 to 200 acres change how we draw a steel building. Great Western Industrial Park in Windsor is a 3,000 acre master-planned park with dual rail interchanges to Union Pacific and BNSF, and industrial buildings there range from 60,000 to 1,000,000 square feet. At that scale, the frame, the dock layout and the track position are all decided together, and a rigid frame with clear spans of the right width is often the lowest cost way to enclose the space.
We erect pre-engineered metal buildings for manufacturers, distributors and trades in and around Windsor. Standard frame bays, insulated metal panels, heavy-duty slabs and the crane or mezzanine options industrial users ask for. We name the snow load and wind package up front and quote a lead time before you sign.
Not every Windsor owner needs a million square feet. A small contractor may need 10,000 square feet of shop and yard. The same frame logic works at both ends, and we can start small with a bay arrangement that extends later. For a younger company, that can mean a first phase sized to your cash flow, with the second phase ready to go when the order book grows.
From a 10,000 square foot shop to a rail-served shell
The park's tenants have included Vestas, Carestream, Front Range Energy, Halliburton, Hexcel, Kodak, Cargill and Schlumberger, a list that shows how many kinds of users sit in one place. Manufacturing wants height and power. Distribution wants dock positions and a flat floor. Energy and ag processors want wide aisles and good truck circulation.
We build warehouse and manufacturing plant shells in those formats, and we draw them with expansion in mind. A frame that can be extended on one end wall saves a lot of money later, because the next bay uses the same column line and the same utilities. A crane industrial building follows the same logic, with runway beams and column sizes set for the heaviest load you may add.
Wind blades, jobs and what they ask of a building
In February 2021 Vestas announced that Windsor would take over wind turbine blade production from its Brighton factory, and the town's economic development director expected about 150 added jobs. Large-component manufacturing is a good example of the building problem we solve: long tall bays, crane service, high slab loads and open yard space for staging.
A developer release in April 2015 counted about 1,500 workers at the park, with about 575 new jobs planned that year. Those numbers are older, but they show the pattern. Employment grows, supplier space grows, and the steel building market follows. If you are weighing Windsor against Greeley or Johnstown for a plant or warehouse, we can price all the parcels on the same terms. The cheapest land is not always the cheapest building, once you count road work, utilities and drainage.
Rail, road and the delivery window
Windsor sits at 4,797 feet in Larimer and Weld counties, with its main business district along State Highway 392 and a BNSF line north of Main Street. For deliveries, that means steel arrives by truck from the interstate side, and heavy loads need a route plan. We schedule trucks to match the erection sequence so material is not sitting on the ground in the wind.
Industrial users with a rail spur should tell us the track elevation, loading position and clearance early, because it affects the slab, the door height and the column spacing. Rail work has its own approvals and track-side safety rules, and we keep the crews out of any live track area. We also plan material laydown so that stacks of panels, purlins and girts are protected from wind and kept off the haul road.
One scope, one price, one crew boss
We start with a short intake: the use, the equipment, the sizes and the timing. Then we return a load package, a frame layout, a price per square foot and a lead time. If the number is too high, we show where we can cut it, such as a shorter eave, wider bays or a simpler door arrangement.
During construction, you deal with one crew boss who knows the plan. We report weekly on progress, on any engineering questions and on what is coming next. For larger buildings, we break the work into pours, steel erection phases and enclosure phases so you can see the building take shape. A manufacturing owner who needs production started by a certain date can see which phase controls the date.
Which jurisdiction reviews your plans
Windsor lies in both Larimer and Weld counties. Code editions in Colorado are adopted locally, so a design that works in one community can need changes in another. The Home Builders Association of Metro Denver tracker dated January 20, 2026 shows how widely editions vary: Adams County, Arvada and Castle Rock on the 2018 codes, Aurora and Arapahoe County on 2021, and Boulder, Golden and Cherry Hills Village on 2024.
We confirm the edition with Windsor's building staff before we engineer, and we check floodplain, fire access and utility requirements at the same time. That avoids surprises when the drawings go in for review. Colorado adds a statewide energy layer too. Any county or municipality that updates its code after July 1, 2023 must adopt an energy code at least as strong as the 2021 IECC, which affects wall and roof insulation and is another reason we price insulated panels for conditioned areas.

Common Questions
Yes. Rail service changes the slab, door height, column spacing and fire access, so we need the track position early. We design the building to the spur, then coordinate with the railroad's requirements for clearances. Crews on site stay clear of live track.
Very large. Buildings in the hundreds of thousands of square feet are built from repeated frame bays. The real limits are the site, the fire code and your budget. We price a few footprint options so you can see the cost for each.
Send us the product, the equipment list and the truck traffic you expect. From those, we can sketch a footprint, a clear height and a dock count, then give you a price per square foot range. Many Windsor owners refine the numbers after seeing the first sketch, and there is no cost to ask.
A crane needs heavier columns, a runway beam and a stronger slab, and the exact cost depends on capacity and span. We design for a future crane if you may add one later, because upgrading afterward is more expensive than planning now.
A master-planned park often comes with design standards, utility stubs and roadway access already in place, and that can shorten site work. It does not replace the building permit. We still confirm the code edition, the fire access and any park design review before drawings are final, and we build those steps into your schedule.
Keep one end wall free of utilities and doors, and ask us to design the end frame to be extended. We also set the site plan so trucks and fire lanes still work after the expansion. This costs little now and saves a lot later.
