Power drives every siting decision for a data center, and in the Basin the conversation about power already runs through energy companies, midstream plants and utility interconnections. For the concrete contractor, that means the first questions are about generator pads, switchgear pads, duct banks and the data hall slab, in roughly that order of urgency. The building comes later in the sequence than most owners expect.
We approach a data center in Midland as a set of heavy, precise concrete packages that must be finished before equipment arrives. Each package has its own tolerance, curing requirement and inspection hold, and each ties to a delivery date for something expensive. A switchgear lineup that arrives before its pad is cured sits in a laydown yard accruing storage charges, and an owner's rep will feel that quickly. Our pour calendar is built to prevent.
Owners and developers behind the project
The companies that plan data centers include technology firms, colocation developers, utilities and energy companies that want computing capacity near their own generation. Most of them arrive with a standard campus design and a strong view on schedule. Utilities and energy companies are a natural partner here, since they already have the interconnection experience and the site control that a power-intensive facility needs.
Commercial developers who build to suit often hire us earlier than general contractors do, because the first work on a data center site is concrete and civil: pads, ducts, access roads and drainage. We provide a concrete budget and a pour calendar to commercial developers long before the building drawings are complete, so the owner can plan the order of procurement.
Midland as a place for power-intensive buildings
Midland sits inside an energy economy that has experience with large electrical loads, gas supply, and fast construction on pad sites. The infrastructure around the city is changing as well. A TxDOT proposal for Loop 250 adds main lanes from Fairgrounds Road out to CR 1150, also called Elkins Road, and puts an overpass over Todd Drive; the public comment window for it closed July 10, 2024. A data center near the Loop 250 and SH 349 corridor should expect changes in access and traffic over the life of the project.
Climate matters for cooling design and construction. At Midland International Airport the 1991 to 2020 normals show about 13.51 inches of precipitation a year, 24 days at or above 100 degrees F and 58 mornings at or below freezing. Low rainfall means dust and wind matter as much as water during construction, and the heat affects cooling loads and the mix design for equipment pads.
Design questions that shape the concrete
The first question is bearing capacity. Generators, transformers, chillers and battery systems concentrate heavy loads on small footprints, and the geotechnical report must cover each pad location, not just the building. We ask for borings at pad locations and compare the report to the structural design before bid. Where soil capacity is marginal, the engineer may call for thicker pads, deeper footings or soil improvement by a trade partner.
The second question is cleanliness. A data hall needs a dust-free floor, so the slab surface is treated, sealed or hardened to limit particles from wear. Howard County sees common dust storms and high winds in early spring and summer, with an average annual rainfall of about 15.88 inches, which gives a sense of the regional conditions that crews work through. We protect finished slabs and keep construction dust out of conditioned spaces.
The third question is duct banks. Underground electrical and fiber routes require coordinated trenching, conduit spacing and concrete encasement. Our electrical duct banks work is sequenced with pads so that elevations match at the building penetration.
Permits, inspections and owner standards
Data center projects are reviewed by the local permit office under the adopted building code, and many owners layer their own standards on top. Those standards often require special inspection of concrete, material certifications, mock-ups for floor finish and detailed commissioning documents. We keep a submittal register that tracks each item and its approval status.
Electrical interconnection has its own approvals that are outside our scope, but they affect our schedule: the utility may set dates for pad readiness and conduit inspection. We build those dates into the pour calendar and keep the owner's rep informed when any inspection moves.
Special inspection is where schedules slip, so we agree on the inspection agency and its notice period before the first placement. Rebar placement, embedded plates, conduit stub-ups and formwork are all inspected before concrete arrives, and we do not call for trucks until the inspector has signed the card. When the owner has a commissioning agent, we share the pour record so the agent can trace every pad to its test results.
What moves a data center concrete budget
The biggest cost items are the heavy equipment pads, the data hall slab with its tolerance and finish requirements, and the duct bank network. A campus with many identical buildings may repeat a standard detail, which allows form reuse and simplifies the crew's learning curve. A one-off facility will cost more per cubic yard.
Haul distance and mix design also add cost. If the batch plant is distant or the mix includes special admixtures for heat control, the price per yard rises. We show those items on separate lines. For related work, see our manufacturing plant and flex light industrial pages, which cover similar slab and pad details for different owners.
The less visible costs are mobilization and standby. Equipment pads are small but scattered, and moving a pump and finishing crew between four pads in one day costs more than pouring one large floor. We group pads by location and curing requirement to keep crews working and trucks moving, and we tell the owner when a revised sequence would save money without moving a delivery date.
Send the pad schedule and the power date
Send the one-line diagram, the pad schedule and the civil drawings. We return a pour calendar tied to equipment delivery dates, with inspection holds and cure windows listed for each package.
Common Questions
What concrete is needed before the building goes up?
Typically the generator and switchgear pads, the duct banks, the access roads and the slab for the first data hall. Large equipment often arrives early, so we sequence those pads first.
How flat does a data hall floor need to be?
The tolerance depends on the raised floor or rack system the owner selects. The engineer states a flatness and levelness requirement, and we confirm it with measurement during placement and again after curing.
Can you work around dust and wind on the site?
Yes. We schedule placements for calm hours when we can, use windbreaks and curing compounds, and clean the slab before sealers go on. Dust control is part of the written pour plan.
Who coordinates with the electric utility?
The owner or the electrical contractor leads the interconnection. We coordinate trade partners and share pad and conduit readiness dates so the utility can schedule its own work.
Do you build the foundations for backup generators and fuel tanks?
Yes. Generator pads, fuel tank pads and containment curbs are within our concrete scope. We coordinate with the fuel system supplier on dimensions and with the engineer on containment capacity, and we pour the containment as a continuous, sealed section when the design calls for it.
