Data Center Construction in Coweta, Oklahoma

Cooling water decides how a data center near a river is built, and in Coweta we begin with where the water comes from, where it goes and how much of the site the mechanical yard will take. Chiller pads, pump rooms, piping and drainage are laid out before the shell, since the building has to fit the plant and not the other way around.

The Arkansas River runs past Coweta, and Tulsa is some 30 miles northwest, which suggests a setting with reliable surface water nearby and flood questions to match. Whether the owner chooses air-cooled equipment, a closed loop or a design that draws on a municipal supply, the decision depends on utility capacity, discharge rules and the groundwater found in the borings.

We schedule, supervise and inspect the trade partners who build the plant, and we coordinate the engineer, the water provider and the owner from the first sketch to the last test.

A central utility plant is often the first building we plan here, followed by a data hall or an edge facility sized to the electrical service. A smaller modular data center can also work on a compact lot when the cooling equipment is delivered as a skid.

We also build the neighbors of those buildings: a gatehouse, an administration building and a generator and fuel yard. Each is placed with the prevailing wind, the drainage path and the neighbors in mind, because the sound of fans and pumps carries farther than most owners expect, and a screening wall or a different orientation is cheaper before construction than after.

Our mechanical yard scope includes chiller and cooling plant pads, pipe racks, buried supply and return lines, pump enclosures, water treatment space and the screening walls that go with them. We detail pad elevations and slopes so that a leak or a washdown flows to a collection point, not toward the building. Where the design uses glycol or treatment chemicals, we add secondary containment and a clear drain plan, and we confirm the discharge path with the city before the pour.

The concrete is heavy and the tolerances are tight. We coordinate the trade partner and the equipment vendor on bolt patterns, housekeeping pads and embedded sleeves before the pour.

The water side of a project is covered by chiller and cooling plant pads and cooling water supply and reuse lines, and a high-density design may add liquid cooling infrastructure coordination.

These scopes share trenches, power feeds and controls, so we organize them as one package. The result is fewer conflicts at the pipe rack and fewer surprises at startup. We model the rack in three dimensions with the mechanical engineer, check clearances for valves and maintenance access, and review the model with the trade partners before fabrication begins.

Tornado season shapes how we plan. In January 2023, the public school district asked voters to approve a $50 million bond, and part of it would pay for three tornado shelters that also serve as gymnasiums. Storm readiness is clearly part of local building culture. On a data center site, that means a written weather plan, secured materials, a defined shelter location and a rule that cranes stop lifting when the forecast turns. We brief every trade partner on the plan the day it mobilizes, and we repeat the briefing when a new crew arrives.

Deep trenches for water lines need shoring, spoil setbacks and daily inspection. We require each trade partner to submit its excavation plan and confined-space procedures before work begins, and our superintendent checks the trench every morning and after any rain.

The Muscogee Nation opened a $100 million casino hotel of 104,000 square feet on March 2, 2026, on the southeast corner formed by State Highway 51 and East 131st Street South. It has 46 hotel rooms and added 250 permanent jobs. On the same highway, at 31350 E. State Highway 51, an 11,810-square-foot building for Indian Capital Technology Center, valued at $2,200,000, was being built as of January 31, 2025.

Projects like these draw on the same suppliers and trade partners as ours, so we confirm availability early, and we plan material deliveries to avoid the busiest hours on the highway. They also show growth along State Highway 51 and a local interest in training, which can help an operator who needs technicians. For comparison, see how we approach Broken Arrow and Bixby, both nearby in the Tulsa metro.

The local building department reviews the building and mechanical permits, and the state environmental and water agencies may review discharge, stormwater and withdrawals. We prepare the submittals with the engineer and keep a log of each reviewer's comments.

A site near the river also needs a floodplain determination. We request it before design is frozen, since a pad that must be raised changes the earthwork, the drainage and sometimes the access road. If the river corridor affects the parcel, the floodplain administrator's requirements go into the drawings and the budget at the same time.

Our approach is to settle water first. We gather demand estimates from the cooling engineer, ask the provider what is available, test options for reuse and decide on the cooling method before we ask the owner to approve a building footprint.

This is part of our preconstruction and estimating work, and it keeps the budget honest, since the cost of pipe, pumps and treatment is shown beside the cost of the shell.

Commissioning is where a cooling plant proves itself. We schedule flushing, pressure tests, water treatment, controls checks and load-bank tests in order, and we invite the operator's staff to witness each one so that they learn the system while it is being proved.

Utility owners and power developers who build near the plant can use the same records for their own acceptance tests. We then assemble the turnover package: test reports, drawings, manuals, warranties and a punch list with owners and dates. The package is organized by system, which saves the operations team hours when they need to find a record.

Send us the load, the cooling approach and the parcel. We will outline the water, drainage and commissioning steps in plain terms.

How do you decide between air-cooled and water-cooled designs?

We compare the water available, the electric load, the climate and the site area. Air-cooled systems use less water but more power and space, while water-cooled plants are more efficient but need supply, treatment and discharge permits.

Is flood risk a concern near the river?

It can be. We request a floodplain determination, set pad elevations above required levels and design drainage so that stormwater does not cross the equipment yard.

What does commissioning involve?

Staged tests of power, cooling and controls, followed by integrated tests under load. The operator witnesses each stage, and results go into the turnover package.

Who installs the piping and equipment?

Licensed mechanical and electrical trade partners install it. We schedule, coordinate, supervise and inspect them, and we manage the interfaces between their work.

Can the plant be expanded later?

Yes. We reserve pad space, valved tie-ins and electrical capacity so a second plant module can connect without a shutdown of the first.
