Hyperscale Campus Construction in Oklahoma

Four buildings on one parcel is a different problem from one building on one lot. The Tulsa Regional Chamber has described a campus north of Tulsa that could reach $3 billion across multiple phases, with up to four facilities totaling close to 1.2 million square feet and first-phase completion scheduled for summer 2027. When a site is planned that way, the shared infrastructure is the real project: the substation, the loop road, the stormwater system and the water supply all have to be sized for a future that has not been built yet.

Hyperscale buyers in Oklahoma are also working at acreage that was unusual a few years ago. A campus spanning 506 acres has been reported in unincorporated Tulsa County west of Owasso, near Cherokee Industrial Park. Land at that scale usually means annexation or a county agreement, a road network built by the developer, and a long timeline of site approvals. We treat the campus as a program of work with its own phases, not as a stack of individual buildings.

We build the civil backbone, shells, mission-critical slabs and yards for these campuses, and we coordinate the owner's equipment contractors through commissioning. The sections below explain how we structure.

The first decision is what gets built once and what gets built per hall. Duct banks, fiber trunks, cooling water mains and the main loop road are installed at campus scale, ahead of any building, because trenching through a live site later is slow and risky. We draw a master utility plan with future tap points stubbed out and capped, so each later phase connects without reopening a completed one.

The second decision is where the cranes and trucks go. A campus with active halls and an active construction front needs a physical separation: its own haul route, gate and laydown yard, and a clear boundary for the security perimeter. Owners who skip this planning step end up with delivery trucks crossing live generator yards. Our phased expansion build-outs work shows how we handle that separation in detail.

Early work covers clearing, mass grading, detention and the haul roads that carry heavy equipment. Once the pads are ready, we place the building foundations and the mission-critical slabs, then erect shells in tilt-up, precast or steel depending on the owner's design. Meanwhile, separate trade teams build the generator yards, chiller pads and electrical duct banks so the equipment pads are cured before the first delivery trucks arrive.

On the largest sites the utility often builds its own substation inside the campus fence. We coordinate that work with the utility's crews and handle the supporting site work, including the access road, foundations and grounding grids the utility specifies. For the full description of that work, see utility substation site work.

On a multi-building campus, the first building teaches the next one. We use the first hall as a production run, recording crew productivity, concrete placement rates and equipment delivery lags, and carry those numbers into the schedule for later halls. By the third building the schedule rests on measured numbers, which is what an owner needs before committing to tenant dates.

Labor is the constraint. Peak construction on large Oklahoma data center projects has been reported at more than 1,000 workers, and a campus can easily compete with itself for finishers and electricians. We stagger hall starts so each trade moves from one building to the next in a steady rhythm rather than showing up all at once. Our fast-track scheduling page explains how we hold pace without sacrificing quality checks.

A campus of this size has no chance of moving without a power plan. We meet with the utility early to learn whether service will come from an existing line, a new transmission tap or an on-site substation, and what the interconnection study will require. Those answers determine the phase boundaries, because a campus is usually energized in blocks as the utility completes its own upgrades.

The county gets equal attention. At campus scale, road improvements, stormwater permits and tax incentive agreements are negotiated, not simply approved. We come to those meetings with a phasing plan, truck traffic estimates and a schedule of when each infrastructure piece will be delivered. At MidAmerica Industrial Park in Pryor, a 9,000-acre campus with about 80 companies, custom electricity comes from the Grand River Dam Authority, a reminder that large-load service in this state is often arranged by the park or the authority, not just the investor-owned utilities.

Shared infrastructure usually carries a larger share of early cost than owners expect, and it is spent before any revenue-producing space exists. That is why we price the master utility package separately and show the owner what it costs to defer each piece. Deferring a duct bank saves money in year one and costs more in year three, when the work has to cut through finished pavement.

Equipment dominates after that: switchgear, generators, transformers and chillers are the largest line items, and their lead times move the budget as much as their prices. We keep a running comparison between the equipment the design assumes and what manufacturers can actually ship, so the owner learns about a long lead time while there is still room to adjust. Our service on long-lead equipment procurement covers how we do.

Most hyperscale campuses are built for cloud providers and for the AI operators who are now competing for the same land. Those buyers are described on our pages for hyperscale cloud providers and AI and GPU cloud operators.

We also work with the developers who assemble land, secure power and entitle sites before the operator arrives. Their needs differ: they want the site ready for any of several tenants and need flexibility in the plan. For a developer without a named occupant, we price the work so the final tenant can adjust the design without a change-order spiral. Our hyperscale data center page covers what happens inside the buildings.

Share the acreage, the power target and the number of phases you expect. We will outline the shared infrastructure and show how each phase can be energized and built without disturbing the last.

How do we decide how much infrastructure to build in phase one?

Build everything that would be difficult to add later and defer anything that scales with load. Main duct banks, drainage, the loop road and cooling water mains belong in phase one. Individual generator banks, chillers and some switchgear can follow the halls. We create a cost comparison so you can see the tradeoff before you commit.

Can the utility energize the campus in blocks?

Often yes. Many utilities prefer to energize large loads in steps, as their own substation and transmission upgrades finish. We plan the phases around those energization dates, and we keep each hall self-contained so one block can go live while the next is still under construction.

What land and zoning issues come up on a campus of several hundred acres?

Annexation or county agreements, rezoning, road-use commitments and stormwater permits all matter. Parcels in unincorporated counties follow county rules, while annexed land follows the city. We run those approvals in parallel with design so none of them waits for the other.

How do you keep tenant-fit-out crews from conflicting with construction?

We give each active building its own gate, laydown area and temporary power, and we establish a clean boundary between live halls and active construction. Haul routes avoid the generator yards of operating buildings, and hot work or heavy lifts near live equipment are scheduled with the operator.

Do you build the shell before the operator is chosen?

We can, for developers who want a speculative building ready for a tenant. The risk is that the tenant will want different column spacing or floor loads. We design speculative shells with enough structural margin and slab flexibility to accept common data hall layouts without rework.
