A plant manager rarely calls us to talk about steel. The call is about a line that has to start on a date, a new press that is already on a truck, or a second shift that needs somewhere to park forklifts. Metal building design-build earns its place with manufacturers because the building is a schedule problem first and an architecture problem a distant second. Broken Arrow is said to hold the third-largest concentration of manufacturers in Oklahoma, and Shawnee alone counts more than 70 manufacturing companies in the surrounding county. Owners in those towns buy buildings the way they buy equipment: on lead time, on loads and on what it costs to be wrong.
The questions we hear most are practical. How tall does the eave need to be for the crane or the stacked rack? Where does the next bay go when the product line grows? Will the floor carry the machine, and who pours it? Will the insurance carrier and the fire marshal sign off on the first try? We answer those in the first meeting, in plain numbers, before anyone talks about color.
This page is for owners and operations managers who need a plant, a fabrication shop, a machining bay or a production addition and want to understand what drives the price, the schedule and the warranty questions before they sign anything.
Most manufacturing buildings we are asked about fall into four groups. The first is a new production shell with a tight bay grid, a few overhead doors and a mechanical yard. The second is an addition to a running plant, where the new frames must tie into an old end wall without stopping the line. The third is a fabrication or machine shop with a runway beam and a crane that has to be designed in from day one. The fourth is a support building: tool crib, maintenance shop, raw material storage or shipping staging.
Each one starts with the same short list. We need the equipment footprints and weights, the tallest thing that will ever be moved inside, the clear height under the lowest obstruction and the way product enters and leaves. A clear-span building keeps columns out of the work area, which is worth real money to a plant that rearranges every few years. If the process needs lifting, a crane-ready industrial building is designed with the runway loads in the frame rather than bolted on afterward, and that difference shows up in both cost and deflection.
Oklahoma sets statewide minimum building codes through the Uniform Building Code Commission. The International Codes apply, while plenty of cities list their own editions, and general contractors need no state license for general work. That mix is the reason we confirm the adopted edition and the local amendments with the building department before we freeze loads on a plant drawing. A manufacturing occupancy also pulls in fire separation, egress, sprinkler design and often a hazardous materials review that a warehouse never sees.
For a plant the permit set usually includes the engineered metal building drawings, the foundation design, the site and drainage plan, the fire protection submittal and the electrical and mechanical packages. We coordinate those so the building department reviews one consistent set. When the insurance carrier has its own list of requirements, we want it early, because a roof class or a sprinkler density requirement found after the order is placed costs far more than one found at quote time.
The crews that matter on a manufacturing job are the ones who touch the structure and the slab. We erect the frame, hang the girts and purlins, set the wall and roof panels and install the doors, and we can run the foundation work and the concrete floor through a vetted partner, depending on the scope. That keeps one party accountable for the foundation bolts landing where the frame expects them. Every steel erector has a story about bolts set an inch off, and none of those stories end quickly.
Inside an active plant we also plan the work around the people. Haul routes, laydown areas, crane picks near live aisles and tie-in days all get written down and shared with the plant safety lead. If an addition needs the old wall opened, we sequence the cut so product keeps moving, then close the opening the same day. That sort of planning is dull to read and expensive to skip.
For a plant, price per square foot is a poor first number. The building might be a modest share of the project once the slab, utilities, process piping, power and the equipment itself are counted. What moves the steel price most is the load: a bridge crane, heavy roof-mounted units, a mezzanine for controls or a deep snow and wind design all add weight to every frame. Insulation, liner panels for washdown, a higher eave and the number of overhead doors come next.
We give owners a line-item budget early, separating the metal building package, the foundation, the erection, the envelope extras and the site work, so a change in one line does not hide inside a lump sum. If a bay can wait for phase two, we say so and show what the future frame looks like, because adding a bay to a building designed for expansion is much cheaper than adding it to one that was not. A planned addition starts at the first drawing, not at the second need.
Plants rarely buy steel alone. Many want mezzanines and platforms for controls, offices or storage over the floor, and an industrial office buildout for supervisors and quality staff. Those pieces tie into the same structure, so we price and design them together instead of in separate bids that argue about who owns the column.
Some owners compare us with the buildings next door: other manufacturers who need a lot of bay height might also look at warehousing and distribution examples for dock layouts, and those who make parts for the air industry often share a campus with the work described on our aviation page. We are happy to talk through either comparison.
Lead time is the number nobody likes. The metal building package has to be engineered, approved, fabricated and shipped, and that run is often the longest single item on the schedule. We start permits and foundation drawings while the package is in the queue, so excavation and footings are ready by the time steel arrives. Pratt & Whitney opened a military engine facility of 845,000 square feet beside Tinker Air Force Base in October 2024, and a project of that size shows what is happening around Oklahoma City: owners are competing for crews and materials, which makes early orders matter.
Midwest City's Soldier Creek Industrial Park was recognized as Site Ready by the Oklahoma Department of Commerce, one of 19 light industrial parks in the state with that certification, and a ready site shortens the pre-construction months. When land is not Site Ready, we check utilities, geotechnical conditions and drainage before pricing, because a surprise there is the usual reason a plant opening slips.
Send the equipment footprints, the tallest lift and your target start date. We will come back with a budget range, the schedule risks we see and what we still need to know.
It depends on the size and on whether the site is ready, but the sequence is fixed: engineering and approvals, steel fabrication and delivery, foundation work, erection, envelope, then interior and commissioning. The package lead time is often the longest single item, so ordering early shortens the whole run. We give a dated schedule after we see your drawings, and we flag the items that can slip, such as utilities or permit review.
Usually yes. We separate the new foundation and frame from the old building as long as possible, then cut the tie-in opening in a planned window and close it the same day. Haul routes, crane picks and laydown get agreed with your safety lead beforehand. Some jobs need a short shutdown for the final connection, and we say so in the schedule instead of pretending otherwise.
Equipment footprints and weights, the tallest item that will be moved, the clear height under the lowest obstruction, the crane capacity if any, door counts and sizes, the occupancy and any insurer requirements. A site plan or survey helps. With those we can give a useful budget range rather than a placeholder number.
The state sets minimum codes, but cities adopt and enforce their own editions and amendments. Many cities list their own editions, while the International Codes apply. We confirm the edition and any local amendments with the building department before we freeze design loads.
It can be, when the insulation, ventilation and door strategy are planned together. Roof and wall insulation limit heat gain and condensation, high-volume fans or mechanical ventilation move air, and dock or overhead doors can be sized to the traffic. Process heat and hot work need their own review, and we ask about them at the start.
Tell us about the site, the building and the schedule, and we will set up a review of scope, schedule and permitting.
