Clear-Span Metal Buildings in New Mexico
A machining company north of Farmington is putting a new 11,000 square foot facility on a 16-acre property beside an existing building it plans to renovate, according to a June 2026 state press release. A shop like that needs open floor. Every column in a machining bay costs you each time a pallet jack, a fixture table or an overhead hoist wants to cross it. That is the whole case for clear span.
A clear-span building has no interior columns. Rigid frames carry the roof across the full width, so everything under them is yours to arrange and rearrange. The price of that freedom is steel: deeper rafters, heavier columns and bigger footings at every frame line. Whether it is worth paying depends on how you use the floor, and a few feet of width can change the answer.
We design and erect clear-span buildings for owners who need the floor open: shops, production space, storage, arenas, equipment barns and hangars. We start by asking how things move through the building, because that tells us where a column would cost you money and where it would not.
Choosing the span before choosing the steel
Modular framing, where interior columns break the width into smaller bays, is cheaper in steel. A true clear span is more expensive per frame but often needs fewer frames, and it gives you flexibility that never goes out of style. We price both options on the same plan so the cost of open floor is a number rather than an opinion. Sometimes a single row of columns down the middle costs a small fraction of the full span and leaves you with a workable layout. Sometimes it ruins the plan.
A wide frame pushes outward at the base as well as down. That means bigger footings, and on some designs the slab is tied across to resist the spread. Your engineer decides which. Soil matters more with a wide span than a narrow one, so we push for a geotechnical report before we commit to a number. On the high desert, where the ground can change within a single lot, it saves arguments later.
Buildings that need the floor open
Production space comes first. A manufacturing plant wants straight lines for conveyors, room for machinery to be reset and, often, a bridge crane that rides on the frame. A logistics or fulfillment building wants a floor with no columns in the pick aisles and dock doors on a regular spacing. Aircraft owners want to put a wing under a roof without a column in the way, which we cover under aircraft hangars.
Ag operators use the same logic. A hay barn, equipment shed or arena has no use for a post in the middle, and our agricultural buildings work leans on clear span for exactly that reason. A building meant to carry a crane gets a heavier frame and runway beams, which we handle through high-bay, crane-ready buildings.
What a wider building costs
Width and eave height are the two numbers that move the price the most. Steel per frame grows faster than width does, because a longer rafter has to resist more bending. Raising the eave raises column weight and wall panel area. Every added door, window and liner panel adds money, and so does insulation on a roof with a lot of area. Snow load matters more as elevation increases, and the frames are designed for the address, not an average.
Distance and site work are part of the bill. A site with no water on it means hauling water for concrete and compaction. A remote site can mean crews lodging near the job. We price both out in the open. If your lot needs fill, drainage or a long utility run before we can start, that is the next biggest line after the steel itself.
Who we build open floor for
Several industries drive our clear-span work. Light manufacturers and machine shops are the obvious ones, and the Farmington expansion above is a good picture of the scale many of them work at. Rail-served industrial parks are another. The Clovis Industrial Park is described by Clovis Economic Development as a shovel-ready, certified industrial site with on-site BNSF railway and Xcel Energy, and its parks list 230 acres available. That sort of site supports warehouses and processing buildings with long clear floors and dock doors along one wall, which fits Clovis.
Small cities such as Moriarty also lease ground to businesses that want to build. The Moriarty Business Park, next to Interstate 40, offers lots for long or short-term lease. An owner building on leased land should talk to the lender first, because a building on ground you do not own is judged differently. Recreation owners come to us as well, and our recreation and sports facility work covers indoor arenas and training space.
Roof water, snow and fire code
A wide roof sheds a lot of water in a short time. A summer monsoon cell can drop a lot of water in a short time, so gutters, downspouts and the site grading around the building have to move that water somewhere that is not your slab or your neighbor. We size roof drainage with that in mind and we do not tuck the discharge against a wall. On sites with snow, we look at drifting where a low roof meets a high one.
Large open buildings also trigger code questions. Floor area, occupancy and use can require fire sprinklers, rated separations and more than one exit. The rules come from the 2021 New Mexico Commercial Building Code, and the local authority interprets them. We sort that out at the concept stage, before the frame width is locked, because a sprinkler requirement can change the economics of a very large span.
What we do on a clear-span job
We take the project from the building concept through foundation, frame, envelope and finish. That includes coordinating the manufacturer's drawings with the foundation design, setting anchor bolts to the tolerances the frame needs, erecting the frames in a braced sequence and closing the building in. Endwalls can be built as bearing frames or as expandable frames that make it easy to lengthen the building later.
We also handle interior layout items that depend on the span, like the structural supports for a crane runway, lighting and hoist points, mezzanines hung off or beside the frame, and large overhead doors. If you have a layout, send it. If you only have a use and a rough footprint, we can work.
Let us price your open floor
Send the use, the width you want and the town. We will return a clear-span price next to one with a column row, so you can see what the open floor costs on your site.
Common Questions
How wide can a clear-span metal building go?
Metal building frames can span very wide, and the practical limit is cost, not steel. Past a certain width, an interior column row becomes cheaper than a deeper rafter, and heavy frames need larger footings and bigger lifts. We price the open version and a one-row alternative, then you choose.
Does a clear span roof need more maintenance?
The roof panels, insulation and fasteners are the same as on a narrower building. The difference is scale: more area to shed water and more eave length to keep clear of debris. We detail gutters, downspouts and expansion points for the full length of the roof.
Can I hang a crane from a clear-span frame?
Yes, but the frame has to be designed for it. A runway beam adds vertical and horizontal loads at the columns, and the foundation has to take them. Tell us the crane capacity and travel before the frames are ordered.
Is clear span worth it for a small shop?
Often yes. For a shop of modest width, the cost of a full clear span is small compared with the cost of working around columns for the life of the building. For a very wide warehouse the balance is different, which is why we price it both ways.
