Tilt-up data center shells in Oklahoma: heavy panels, power and cooling pads, security, utility timing and the campuses now announced across the state.
Power arrives later than the walls, and that single fact shapes how a data center shell is built. The utility interconnection, the substation and the generators can take years to deliver, while the concrete envelope that will house the servers can be up in a season. A shell contractor therefore works in a strange rhythm: finish the building fast, then wait while the owner's power and cooling teams catch up, and keep the building dry, secure and ready to receive equipment the whole time.
Tilt-up suits the shell for good reasons. Thick concrete panels give a data hall mass, fire resistance and security against forced entry. Large floor plates with few interior columns allow flexible rows of racks, and tall panels let the roof carry cooling units and cable trays. The owner's design team often specifies the structural criteria, and our task is to deliver the panels, slab, roof and site to those criteria.
This page explains what a shell includes, how Oklahoma's announced campuses influence the market, and where owners should plan their budgets and schedules.
Oklahoma has become a visible data center market. A $1 billion, 2-million-square-foot facility was announced in April 2026 for the 2,000-acre Fair Oaks industrial innovation park in east Tulsa, expected to be operational in 2028 with more than 1,000 construction jobs at peak. North of Tulsa, a multi-phase campus on unincorporated land was announced in October 2025 that the regional chamber said would reach $3 billion, with up to four buildings totaling close to 1.2 million square feet and first-phase completion scheduled for summer 2027.
A separate campus of 506 acres in unincorporated Tulsa County west of Owasso was reported in August 2026, and in Sand Springs the city council approved a project on 827 acres of annexed land in February 2026, with construction planned to start in 2027 and finish by 2029. These are announcements, not guarantees, and owners should treat schedules as plans that can move.
The most important approval for a data center is not the building permit but the utility. Oklahoma's Department of Commerce states that the state produces 61 percent more energy than it consumes, that renewables generate 47 percent of its electricity and that energy costs run 17 percent below the national average. Those facts attract owners, but each site still depends on a specific substation, a line capacity and a utility schedule. We ask for the utility letter before we price.
The state code commission adopted the editions of the International Building Code, while some city pages list editions, and we confirm which one governs. Zoning is another gate. In Enid, four proposed campuses were reported in September 2026 with developers estimating up to $35 billion of investment, rezoning filed for two sites and no city approval yet. That case is a reminder that entitlement can be the longest part of the schedule.
A typical data center shell includes the site, the foundation, the slab, the tilt-up wall panels, the roof structure and membrane, and the exterior doors and loading dock. The mechanical yard, generator pads and substation pads are built with the shell or just after it. The floor slab needs a flatness and load rating that suits the owner's racks and raised floor system, if there is one.
Panels are often thicker and taller than a warehouse, with extra connections for the roof and for equipment loads. The notes on panel connections and embeds explain how plates and bars are cast into panels so the owner's trades can attach cable trays, supports and cooling lines without drilling later. Fire and water lines for the site follow the guidance in site utilities and fire lines.
The schedule for a data center shell is set by the longest items: power, switchgear, generators, chillers and transformers. We build the shell so that it is complete a few months before the first equipment delivery, with the building dry and secure. That means the roof is on, the doors are in and the site drains. Interior fit-out by the owner's trade partners then begins in a clean environment.
Owners who have several buildings planned on one campus can repeat the shell design, taking advantage of formwork and crew learning. A phase might add one building at a time as customers sign, with site work extended in advance. We schedule the early site work to avoid trenching a second time, and we talk to the owner about the costs of holding a finished building empty. The page on long-lead procurement describes how we order and track items.
Data center owners ask for security at the construction stage: fenced sites, badge access, logged deliveries and background-checked workers. We plan for these rules from the first day, including a controlled entrance for trucks and a separate lane for visitors. The owner's security team will often review our site plan and the temporary lighting.
On lift day, the usual rules about wind apply. Spring in Oklahoma brings strong gusts and sudden storms, and the crane stays down when the forecast is poor. A large campus means more panels, which means more lift days, and each one is a decision about weather. We keep the owner informed through a simple morning message stating whether the crane will fly that day.
The shell is a small share of the total cost of a data center, because the equipment, power and cooling dominate. For the shell itself, the main drivers are the panel thickness, the slab specification, the roof structure and the site work required for generators and mechanical yards. A change in rack density can alter the roof load and the mechanical pads, so we ask for the preliminary design early.
Site costs vary with the land. A greenfield campus needs roads, drainage and utilities, and owners should consider grading to a single large pad versus several smaller ones. Our speculative industrial shell experience helps when an owner wants a shell built before the final user commits. A manufacturing plant next door may share some of the same utility corridors. For funding partners, the industrial developers and REITs page describes how we report cost.
We are a tilt-up shell builder, and we are plain about where our scope stops. We build the envelope, the slab, the roof and the site. We coordinate with the owner's mission-critical contractors, but we do not pretend to design or install the power and cooling systems. In Chickasha, a joint venture to supply on-site power at an industrial park for data centers, critical minerals processing and advanced manufacturing shows how often power and shell are decided together, and our role is to make the building ready when the power plan lands.
If you are comparing sites or sorting out phasing, send us what you have and we will give you a practical view of the shell schedule and cost, with the open questions listed.
Tell us the site, the building size and the power timeline. We will return a shell concept, a schedule and the questions that need answers first.
We build the tilt-up shell and the site. The power, cooling, security and white-space systems are normally handled by the owner's mission-critical team. We coordinate access, sleeves, pads and schedule with them.
Concrete panels give mass, fire resistance and security, and they go up quickly. Large floor plates and tall walls suit rows of racks and rooftop equipment. Tilt-up is also economical on large buildings.
Utility power and long-lead electrical equipment. The shell can be complete long before power arrives, so we help the owner plan the shell date against the equipment dates, not ahead of them.
Yes, as a speculative shell, though it carries risk because tenants often have specific requirements. We design with flexible loads and leave the interior open.
As a plan, not a contract. Several announced campuses are in different stages of approval, and schedules can shift. We recommend confirming zoning and utility commitments before relying on a date.
Send the site, the building, the schedule and the decision you need to make, and we will set up a project review.
