Tilt-up warehouses and shop buildings for Duncan industrial parks near U.S. 81 and Halliburton Field, built in a clear order from slab to roof.
Small industrial parks are where a great deal of Oklahoma tilt-up work begins, and Duncan has three of them. An October 4, 2022 report said the Eastland, Northland and South industrial parks in Duncan share $1.4 million in federal ARPA funds and $1 million in state PREP money. That kind of money goes into streets, utilities and site readiness, which is exactly the work that decides whether a developer can put a panel casting bed on a lot and start a schedule. We build tilt-up warehouses, shop buildings and light industrial shells, and we price them on the ground an owner is actually looking at.
When an owner calls about a lot in one of those parks, our first questions are practical. Where does the utility stub sit, how deep is the clay, and how does a crane get in and out on lift day? A park with fresh infrastructure can still have a lot that drains toward the building, a street too narrow for a truck-mounted crane to swing, or a power service that needs a new transformer. We walk the lot with the owner, sketch the panel layout on the future slab, and explain in plain order what happens: grade, cast, lift, brace, frame, roof, finish.
Tilt-up suits this part of southwest Oklahoma because the shell is mostly concrete cast right where it will stand. There is less hauling of finished wall material over long distances, and the building gets a hard, fire-resistant envelope that fits shop, storage and service uses. The sections below describe how we handle the site, the permits, the weather and the schedule for a Duncan project.
Duncan is served by U.S. Route 81 and State Highway 7, and Halliburton Field is owned by the City of Duncan and located two miles south of town. For a distribution or service tenant, that pairing of a north-south U.S. route and a state highway is the whole logistics story: trucks leave the park, reach the highway in minutes and can serve customers across the southwest corner of the state without crossing a metro. We design truck courts and dock aprons with that traffic in mind, sized for the trailers the tenant really runs.
The history here is industrial, and it shows in the labor pool. The Encyclopedia of Oklahoma History and Culture says that in the mid-1950s one oilfield services employer had 1,750 people in Duncan, equal to 25 percent of the city's working population. That is a historic figure and we do not lean on it as a forecast, but it explains why shop buildings, equipment yards and heavy-duty slabs are familiar here. Owners in Duncan tend to know what a loaded forklift or a service truck does to a floor, and they ask for slabs and aprons that match. For the larger picture of how the work is organized, see our tilt wall building construction page.
Most of the buildings we are asked about in a park like this fall into three groups: a speculative or owner-user warehouse of 20,000 to 80,000 square feet, a service and repair shop with tall overhead doors, and a small multi-tenant building cut into bays. Each is a good fit for panels cast on the building slab. We pour the casting slab as part of the floor, so no work is wasted, and we sequence panels so that the crane works from one side of the building to the other without crossing its own pick path.
Inside the shell we plan joists and deck to carry mechanical units, crane rails or heavy shop equipment if the owner needs them. The joist and roof deck framing crew we coordinate sets steel soon after the panels are braced and connected, which stiffens the walls and starts the building toward a dry roof. Dock doors, man doors and window openings are placed in the panel drawings, not cut later, so the owner sees each opening on paper well before concrete is poured.
Halliburton Field has a concrete runway 6,326 feet long and 100 feet wide, and the Oklahoma Aerospace Commission lists its role as Regional. A lot near an airfield can bring height limits, lighting questions or review by the airport owner, which in this case is the city. We ask early whether a parcel sits close enough to the field for those questions to matter, and we put the answer in the preconstruction schedule rather than discovering it during permit review.
Statewide, the Oklahoma Uniform Building Code Commission has adopted the International Building Code with amendments, though cities adopt and enforce their own editions and amendments. We confirm which edition the city will review a given permit under and design to it. Our permitting and inspections process lists every review the building passes through: site plan, building, fire, utilities and any state or federal item, so nothing waits in someone else's inbox.
The National Weather Service Norman office lists an EF3 tornado on 11/03/2024 from 5 S Comanche to 7 NW Velma in Stephens County that injured 6 people. That is a reminder that Duncan sits in a county with real severe weather, and it shapes how we run the most exposed days in tilt-up work, when panels stand braced but the roof has not yet tied them together. We watch the forecast for wind and storms ahead of every lift, set the lift for a calm morning and keep a decision point the evening before when we can still move it.
Once panels are up, temporary panel bracing is sized for the wind the engineer specifies for the exposed condition, and the braces stay until the roof deck and connections make the building stiff. We do not shortcut that step to save a week. If a front is coming, we hold off on setting the last panels, secure what is standing and wait. Owners hear this plan before the job starts so that a delay for wind is a decision they expected, not a surprise.
For a 40,000-square-foot warehouse, we usually plan around a rhythm of site work, slab, panel casting, a wait for panel strength, then a lift that takes a few days. Casting waits on concrete strength, not on a calendar date, and the crane is booked only after the engineer signs off. Joists, deck and the roofing system follow, and the building is dried in while slab joints are sawn and dock work is finished inside.
Long-lead items such as joists, overhead doors and electrical gear are ordered as soon as drawings allow, since they can run longer than the walls themselves. We cover that in long-lead procurement. An owner who knows the tenant's move-in date can hand it to us on day one, and we work backward from it, naming the dates that matter: slab, lift, dry-in, power on and final inspection. Duncan owners who compare options in nearby Chickasha or Lawton can have us price the same building in each place.
Give us the park, the lot number if you have it and the building you have in mind. We will return a panel layout, a lift sequence and the list of reviews your permit will face. See also our manufacturers page for plant owners.
Yes. We start by walking the lot, checking utility stubs, grade and crane access, then sketch the panel layout on the future slab. Park infrastructure funding helps with streets and utilities, but each lot still needs its own drainage and pad plan. We include those items in the first estimate so the owner sees the whole cost.
That depends on the lot and on what the airport owner and the city require. We ask early whether the parcel is near the runway or its approach, because height, lighting and review questions can affect the design. The city owns the field, so the same city offices often handle both questions.
Mostly it affects lift days and the weeks before the roof is tied in. We watch forecasts, choose calm mornings and keep panels braced to the engineer's wind criteria. If a front is coming we stop setting panels and secure the site. Owners should expect a few weather days in any spring schedule.
U.S. Route 81 and State Highway 7 serve Duncan. We size the truck court, the entrance and the dock apron for the trailers the tenant runs, so the layout works with those routes rather than against them. Turning radius and queuing space matter more than most owners expect.
We can plan joists, columns or a runway to carry a crane when the owner needs one. The engineer sets the loads, and we coordinate steel, panel embeds and slab thickness around them. Tell us the crane capacity at the start, because it changes the whole structure.
Send the site, the building, the schedule and the decision you need to make, and we will set up a project review.
