A colocation tenant signs a lease against a date, not a design, and the operator who built the building owes that date to a dozen customers at once. That changes how we plan. Wholesale and retail colocation buildings are built in repeatable data hall blocks, each one sellable on its own, and the construction schedule is really a delivery calendar for those blocks.
The economics favor builders who can finish a hall on time and hand it over clean. Colocation operators also need flexibility inside the building: cage layouts that change, power densities that creep upward, and customers who want their own cooling loops. We build the base building to take that change without cutting concrete or pulling new feeders through finished space.
In Oklahoma the pattern is a little different from a coastal market. Land is cheaper and, per the state's commerce department, energy costs run 17% below the national average, so operators can build larger halls on simpler sites. We work with colocation owners and the developers who finance them, and we deliver everything from powered shell to turnkey data halls.
We sequence a colocation building around the block that can be sold first. The shell, the site utilities and the shared electrical room go in once. Individual data halls, with their own distribution boards, cooling and fire suppression, are completed in the order the leasing plan expects tenants to arrive.
That means the first block gets full commissioning while the second is still being framed. We build protective separations, positive-pressure barriers and dedicated construction power so dust and vibration never reach the live hall. Owners who want their later blocks to follow quickly can also read about phased expansion build-outs, where this approach is described in more detail.
The Oklahoma Department of Commerce described a project in a Chickasha industrial park in June 2025 that includes a joint venture to supply on-site power for sectors such as data centers, critical minerals processing and advanced manufacturing. The announcement matters for colocation because it shows developers are bundling power with land, which shortens the wait that usually follows an interconnection request.
Public infrastructure money is also reaching industrial parks. In Ardmore, leaders reported in June 2024 that they had secured $47 million from the PREP fund for airpark infrastructure upgrades, with railway construction scheduled and a further $25 million in upgrades. Sites with roads, rail and utilities in place are the ones that fit the timelines of colocation buyers, who cannot wait on a long civil package.
A typical colocation project in our hands begins with site work and utilities, followed by a shell with a dedicated meet-me room and carrier entrance. Inside, we frame the data halls, install raised-floor or slab-on-grade systems, set electrical rooms and battery spaces, and rough in mechanical distribution. Outside, we build generator yards, cooling plant pads and the fuel systems that serve them.
Owners decide how much of the interior we finish. Some want a powered shell and will complete the halls with their own contractors, others expect fully commissioned halls with cages ready for tenants. We price both options and describe the handoff clearly. Our data hall fit-out page covers the interior scope in full.
The electrical system carries the most review. Oklahoma adopted a newer National Electrical Code, and electrical licensing exams moved to that edition, so the trades we hire are current on its requirements. A city may still list an earlier edition, which is why we confirm the governing code at the building department before plans are final.
Colocation buildings also raise questions about occupancy classification, fire suppression and generator fuel storage that the local fire marshal will want answered. We bring those questions to the first plan review meeting. For the broader permitting picture, including utility agreements, see permitting and utility interconnection.
The core product is the colocation data center itself, ranging from a single-floor facility to a multi-hall building. Related spaces include the carrier hotel and meet-me room, where network providers interconnect, and the network operations center that monitors the building.
These support rooms have different requirements from the halls: more fiber pathways, tighter security, and sometimes a different fire suppression approach. We design the construction sequence so the meet-me room is available early, because carriers need time to light their circuits before tenants can move in. Our page on the carrier hotel and meet-me room describes that work.
Colocation owners often ask us to handle integrated systems commissioning, in which electrical, mechanical and controls are tested as a single system before tenants arrive. We schedule that testing in blocks so each hall can be certified separately.
Many also use our colocation and wholesale operator services for long-term site planning, because the same land that supports today's hall is expected to support five more.
When a second building goes up next to a live one, the greatest risk is to the tenants. We run hot-work permits, lift plans and lockout procedures through the operator's own change-management process, so no crane swing or energized tie-in surprises the control room.
Dust control, vibration monitoring and clean construction practices are written into our site plan. Our approach to clean work is covered in construction cleanliness and safety.
Tell us when your first tenant expects to move in and how many blocks follow. We will return a construction calendar built around those dates and the utility timeline.
It is whatever the lease says. Common options are powered shell, shell and core with electrical and mechanical rooms complete, or a finished data hall ready for cages. We document the handoff in a punch list with test results, so the tenant contractor starts from verified conditions.
Separate the two physically and electrically. We use a dedicated construction entrance, temporary power and positive-pressure barriers, and we schedule tie-ins to live systems with the operator. Any work that touches energized equipment is planned with the operator in advance.
Often it needs more flexibility. Operators change cage layouts and rack densities over time, so we design the slab and the floor loads to handle heavier equipment than the first tenant needs. Our mission-critical concrete slabs page explains how we flatten and cure those floors.
The answer depends on the structure, the site and the long-lead equipment. We do not quote a single number because the electrical gear usually decides the date, not the walls. In our planning, we start with the energization date from the utility and work backward to a construction start.

Tell us about the site, the power and cooling plan and the schedule, and we will set up a review of scope, schedule, permits and inspections.
