Data Center Construction in Pryor Creek, Oklahoma

Turnover is the point where a data center starts to earn money, and in Pryor Creek we plan commissioning before we pour the first slab. Mayes County already has a record of large technology projects, so an operator can expect local officials and the utility to understand what a power-dense building needs.

In March 2022, Northern Data said it would invest at least $270 million at MidAmerica Industrial Park and hire 150 people at first, aiming for 300 Oklahoma employees over time. In February 2018, Google announced a $600 million expansion of its campus near Pryor, with another four-story data center and a workforce already above 400. For a builder, such announcements point to a market that understands why commissioning, redundancy and security matter.

We act as coordinator for the owner, scheduling and inspecting the trade partners while we plan every functional test toward a clean handoff.

Commissioning does not begin at the end of the project, and we do not treat it that way. Handoff quality depends on integrated systems commissioning, supported by data hall fit-out and battery and UPS rooms. Each service has test points that must be reached in order.

We write the commissioning plan during design, assign witnesses and ask each equipment vendor to supply startup procedures. That prevents a test script from being invented after the equipment is already in place. Vendors who know the witness list and the acceptance criteria in advance tend to arrive prepared, and that saves days at startup.

Enterprise tenants, regional colocation providers and carriers fit out halls in existing or new shells, and enterprise and financial institutions often want controlled access, documented testing and a predictable outage window.

Colocation and wholesale operators want repeatable halls that can be delivered in phases. We organize the work so the first hall can go live while the next one is under construction behind a protected partition.

We work in Pryor Creek and the surrounding area, including parcels in and near MidAmerica Industrial Park. The park occupies 9,000 acres, and 116 of them hold the Northern Data campus, so the area already has large parcels with industrial infrastructure in place.

A groundbreaking for The District, a mixed-use development on 162 acres, took place on September 15, 2018, along with news of new greenfield sites of 600 acres (Igloo Valley) and 500 acres (Ridgeline) backed by $15 million of infrastructure spending. For sites outside the park, we compare options in Claremore and Owasso.

Fit-out scope varies, but the sequence is familiar. A fit-out begins with an existing or new shell and adds raised floor or slab-on-grade layouts, containment, power distribution, cooling units, fire detection and security. We coordinate the installation sequence so that dusty work is finished before sensitive equipment enters the room.

The work is done by licensed trade partners under our supervision, with a superintendent on site who knows the drawings and the test plan. We inspect conduit, cable tray, piping and controls at set points before covers go on, and we log each inspection. Photographs of concealed work go into the record, so the operator can see what is behind a wall years later.

We build the schedule backward from the commissioning window, which is the date the operator cares about most. If the operator wants to turn over in a given month, the integrated test must start weeks earlier, and every system must be ready before.

Long lead times on UPS equipment, switchgear and cooling units are tracked weekly, together with the vendor's factory test dates, which the operator may want to attend. We show the owner which items are critical and which have float, and we update that view each week as manufacturers confirm ship dates. An early look at a late UPS delivery is worth much more than a late look at a missed milestone.

Fit-outs next to live equipment need strict controls. We require energized work permits, lockout and tagout, clear labeling and separate access routes. A dust or vibration problem in an occupied hall can cost an operator more than the construction itself.

We coordinate with the local fire authority on suppression, detection and egress, and we confirm that the fire alarm tie-in is tested before the first rack is powered, and we inspect temporary partitions before any work begins near live racks. Sticky mats, negative air machines and daily cleaning keep dust out of the occupied hall, and we measure particle counts if the operator asks.

The first hall sets the pattern for later ones, and owners who think about the third hall while building the first one pay less for it. Structural capacity for heavier racks, space for additional cooling units and spare breaker positions are inexpensive to include at the start and expensive to add later.

We discuss those options with the owner and identify what can be left as rough-in. Sleeves through walls, spare conduits and extra pad space are cheap to include, and an operator that plans for 30 percent growth rarely regrets it. A well-planned edge or colocation hall can grow with its tenants, adding racks, cooling and power in measured steps, and our phased expansion build-outs approach shows how.

The largest cost drivers are the electrical gear, the cooling units and the redundancy level. Moving from a lower to a higher redundancy tier changes the equipment list, the room sizes and the commissioning scope.

Security, fire protection and controls are the next group, along with temporary power during construction and the cost of working around live equipment. Night and weekend work for tie-ins carries a premium that belongs in the budget from the start. We estimate each with vendor quotes and give the owner a clear range, along with the assumptions behind it. Allowances are labeled as such, and we tell the owner when a number is a quote and when it is an estimate.

Describe the hall, the redundancy level and the date you want to turn over. We will outline the commissioning sequence that gets you there.

When should commissioning planning begin?

During design. The plan sets test points, witness roles and documentation requirements that the drawings and the equipment orders must support.

Can a new hall be added beside a live one?

Yes, with protected partitions, controlled access and vibration and dust monitoring. We also plan tie-ins so outages are short and approved in advance.

What is in the turnover package?

Test results, as-built drawings, manuals, warranties, spare parts lists and a punch list with owners and dates. It is organized by system.

How do large technology announcements nearby affect scheduling?

They can tighten the supply of electricians and mechanical trade partners. We ask for commitments early and carry the dates in the schedule.

Who does the physical work?

Licensed trade partners do it. We schedule, supervise, inspect and coordinate them, and we answer to the owner for the result.
