Data Hall Fit-Out Space in Texas

Industrial vacancy in the Houston area stood at 6.8 percent in the second quarter of 2026, according to a regional report, and that figure hints at a choice many data center owners face: buy or lease finished shell space and fit out a hall inside it, or build a new building from the ground up. Fit-out space is the product of that first choice. It is the interior of a building, whether new or existing, turned into a working data hall.

The work starts after the shell is weathertight and has a sound slab. The fit-out contractor installs the electrical distribution, the cooling system, the fire protection, the cable pathways, the controls, the containment and the finishes, then hands the room to the owner's commissioning team. It sounds like interior work, but it is the part of the project where nearly all of the cost, risk and schedule uncertainty sits.

We approach fit-out from the plant backward: how power gets into the room, where heat leaves, and how air or liquid moves in between. The room layout follows.

A hall fit-out typically includes power distribution units or busway, floor or overhead cable pathways, in-row or perimeter cooling or liquid headers, containment for hot and cold aisles, fire detection and suppression, leak detection, security devices and lighting. Floors are sealed, ceilings are cleaned or removed, and walls are finished to a standard that does not shed particles.

Our data hall fit-out scope also includes the commissioning support that every system needs: startup, testing, deficiency tracking and documentation. We coordinate with the owner's integrated systems commissioning agent so tests happen in the right order and a failed test is traced to the right trade.

Texas developers deliver large industrial buildings on spec. In Katy, a developer started a 433,300 square foot building for a five-building project on roughly 78 acres along the Grand Parkway, and another warehouse could be split into suites as small as 9,500 square feet. Buildings like these have the clear height, roof and slab that a modest data hall can use, though they rarely have the electrical service.

In Taylor, a 135,000 square foot data center is reported to be slated for an 87.97 acre tract, which suggests that new data center buildings are being planned in the Austin area as well. Both examples show the range of fit-out starting points. Our Taylor page and our Houston page describe what we see in those markets.

The State Energy Conservation Office continues to list the International Energy Conservation Code for commercial buildings, and cities may adopt later editions locally. Data halls consume large amounts of energy, so envelope, lighting and mechanical provisions of the energy code are part of design, and some of the code's compliance paths do not fit mission-critical load. We review the path with the local building department early.

The permit also has to match the use. A warehouse converted to a data hall changes occupancy and fire protection requirements, which can trigger sprinkler, egress and structural reviews that surprise owners who assumed the building was already approved.

Dust and debris are the common enemy of electronics, so the order of work matters. We finish all overhead work first: sprinkler lines, conduit, trays, lighting. Then we seal the floor and clean, then bring in equipment last. A fit-out that follows this sequence can be cleaned once and kept clean, and a fit-out that does not has to be cleaned again and again.

Our rules are documented in construction cleanliness and safety. They cover entry mats, tacky mats, filter changes on construction air handlers, controlled access to the hall, and a final cleaning before equipment moves in.

Fit-out space often belongs to real estate developers and site owners who build the base building and finish halls as tenants sign. For them, the fit-out package is a menu: a basic hall with power and cooling, an upgraded hall with higher density, and an optional liquid cooling spine. We price each so the developer can quote tenants quickly.

Operators then use the finished space as a colocation data center suite or as a branch hall for an enterprise tenant, and the room may link to a network operations center for monitoring.

Electrical distribution is the largest piece, followed by cooling, then containment and controls. Busway is faster to install and reconfigure than conduit and wire, but it costs more up front, and the owner chooses between flexibility and first cost. Liquid cooling headers add pipe, pumps and leak detection, and they change the structural load on the floor and ceiling.

Finishes are a small share of cost but a large share of risk: a sealed floor that fails inspection delays equipment delivery, and a ceiling that sheds particles forces cleaning after racks are in. We spend on those items deliberately.

Fit-out has fewer weather risks than site work but more dependency risk. Each trade needs the one before it to finish, and each piece of equipment has a lead time. We put the equipment delivery dates on the master schedule, tie each to a physical readiness date in the room, and hold weekly walkdowns with the owner and commissioning agent.

When a delivery slips, we resequence interior work so crews stay productive: containment and lighting can proceed while a chiller waits, and cable pathways can be completed while a switchboard is delayed. A fit-out that is planned this way finishes closer to its date.

Send the building plans and the target density. We will survey the slab, roof and service, and return a fit-out scope and schedule.

How long does a data hall fit-out take?

It depends on equipment lead times more than on labor. A hall can be built quickly when switchgear, cooling units and containment are on site, and slowly when they are not. We build the schedule from the owner's delivery dates and the commissioning plan.

Can any warehouse be fitted out as a data hall?

Not any. The roof must carry the added loads, the slab must be flat and strong, the electrical service must reach the site and the fire protection must meet the new use. A feasibility review, including a slab survey, tells you quickly.

Who pays for the electrical service upgrade?

That is a lease and utility question, but it frequently decides the economics. We estimate the service and distribution work separately so the owner can negotiate with the utility and the landlord with a clear number.

What does commissioning add to the schedule?

Testing takes the time it takes, and failures cost more days. We plan factory tests, site acceptance tests and integrated tests with the commissioning agent, and keep contingency for repairs.
