Data Hall Fit-Out and Conversion in Katy, Texas

West of Houston, a growing belt of light-industrial buildings along the Grand Parkway offers owners a way to put small and mid-sized computing capacity into place without ground-up construction, and in Katy we turn those buildings into working halls. We handle data hall fit-out space inside new speculative warehouses, build the electrical and cooling yards beside them and commission the result. The approach suits edge operators, enterprise teams and colocation providers who want a fast, repeatable deployment close to the western suburbs.

The supply of buildings is documented in local reporting. A developer began construction on a 433,300-square-foot building at the intersection of the Grand Parkway and Clay Road in 2019, with plans for five buildings ranging from 165,100 to 433,200 square feet across roughly 78 acres. In July 2025, another developer was ahead of schedule on a 97,000-square-foot warehouse along Highway 99 that could be divided into spaces as small as 9,500 square feet. In August 2026, a wind-turbine maker was reported to have leased a 131,300-square-foot warehouse and office facility at a 17-acre property about a mile south of Interstate 10 and Woods Road.

Taken together, those reports describe a market that favors flexible bays and quick tenancy. They also describe buildings with specific physical features: dock doors, clear heights, wide column grids and slabs designed for warehousing. Each feature either helps or hurts a data hall, and our job is to find out which before the lease is signed.

A speculative warehouse is built for racking and forklifts, not for servers. Its slab is usually thinner than a data hall would like, its power is modest, its roof is designed for little more than its own weight and its fire protection is tuned to stored goods. We survey each of these in a few days and tell the tenant what the conversion will require.

The typical work includes a new electrical room built inside or beside the bay, a roof-mounted or ground-mounted cooling plant, a hot-aisle or cold-aisle containment system and a security envelope within the larger building. For small tenants, the right answer may be an entirely prefabricated electrical and cooling skid placed behind the building, as covered in our description of the modular data center building type.

Local reporting in May 2026, citing Harris-Galveston Subsidence District data, said parts of the Katy area have sunk about 14 inches over a period that begins in 2007, with one monitoring station recording more than 14 inches between 2007 and 2025. Subsidence of that size affects slab-on-grade buildings, underground utilities and drainage. A rigid, heavily loaded data hall is more sensitive to differential settlement than a lightly loaded warehouse.

Our response begins with a review of the building's foundation type and the geotechnical record, followed by monitoring points on the slab that we read before, during and after the fit-out. For heavy equipment, we place isolated footings or pile-supported pads and use flexible connections for piping and conduit. The costs are modest when planned at the start and large when added after a crack appears. The same attention to ground and drainage drives our stormwater and detention designs.

A fit-out in an existing shell can be much faster than a new build, but only if long-lead items are ordered early. Switchgear, UPS systems, generators and chillers have lead times that are often longer than the construction itself. We help tenants place orders as soon as the lease is signed, and we line up delivery with the building's readiness.

The Grand Parkway segment from I-10 near Katy to US 290 near Cypress is a 15.2-mile, four-lane controlled-access toll road that opened in 2013, and it connects the area's industrial parks to the western and northern suburbs. For deliveries, it gives trucks a route that avoids the Katy Freeway during peak hours. Our fast-track scheduling approach uses these routes to plan oversize loads for off-peak windows.

Because the area's tenants include a wind-turbine maker and warehouse operators, the surrounding businesses are industrial and logistics-oriented. They run warehouse management systems, supply chain software and plant controls that benefit from low-latency local compute. At the other end are suburban healthcare, schools and municipal services that need dependable networks.

These needs fit the edge segment. Owners on that path can read more under telecom and network carriers, which often supply the connectivity to such sites. If the Katy parcels do not fit, a nearby market such as Sugar Land or Houston proper may offer a better match, and we can compare them.

The largest items in a fit-out are the same as in any hall: electrical distribution, cooling and controls. Where a conversion differs is in the cost of fixing the building to carry them. Strengthening the roof for rooftop units, thickening the slab under heavy cabinets and upgrading the service entrance are the main variables. We list them in the proposal as separate lines so that the owner can see what the building adds or subtracts.

Lease terms also matter. Improvements that the landlord keeps at lease end are worth less to the tenant, so we help owners think about which items are mobile, such as modular units and skids, and which are fixed. That distinction can change the choice between conversion and a ground-up building. We also ask the landlord early about roof penetrations, outdoor equipment space and the right to run new conduit, because a lease that forbids them ends the conversation no matter how good the slab is.

Share the building address or plans, the load you need and the lease terms. We will return a conversion assessment with the major costs and the schedule.

Can a speculative warehouse be converted into a data hall?

Yes, in many cases. The slab, roof, power and fire protection need review. Small halls can be built inside a bay, and larger ones may need new structures beside it. A short survey tells us which approach is practical.

How does subsidence affect a Katy building?

It can cause differential settlement in slabs and strain on underground lines. We review the foundation, monitor the slab during fit-out and use isolated or pile-supported pads for heavy equipment, with flexible connections for pipes and conduit.

What size bay is suitable for a small hall?

Bays as small as 9,500 square feet are reported in some local buildings. That is enough for a small hall with a separate electrical room, depending on the load. We test fit layouts before recommending a space.

Do I have to build my own power?

The building has a service, but it is usually sized for warehouse loads. Most data halls need a larger service, a new transformer or both. The utility decides the timeline, so we recommend starting the request early.

Can I get a modular unit instead?

Yes. A prefabricated power and cooling module placed behind the building is often faster than building rooms inside. The choice depends on the landlord's approval, the space available and the load.
