Data Center Construction in the Southern Dallas Inland Port

Large parcels beside an intermodal rail terminal and three interstates are what a campus-scale data center needs, and southern Dallas County is where that combination exists. We build mass-graded pads, shells, mission-critical slabs, heavy truck courts and utility yards for operators and developers who need acreage and a clear path for equipment. We start with the power requirement, then size the grading, the drainage and the road network to carry it.

Union Pacific's Dallas Intermodal Terminal sits partly in Wilmer and partly in Hutchins. Wilmer is on I-45 with ready access to I-20 and I-30 and lies about 14 miles south of downtown Dallas, while Hutchins, about 9 miles south of downtown, is served by I-20 and I-45 and has many industrial and manufacturing businesses. Lancaster adds I-35E along its western boundary and I-20 on its far north side.

Dallas developed an inland port because railroads, interstates and DFW Airport converge here, and the southern end of the county is where that logic plays out on open ground. A builder with experience in grading and paving at that scale is as important here as one with experience in electrical rooms, and we bring both.

The first work is earth. A large pad needs a grading plan that balances cut and fill, controls erosion, protects drainage channels and leaves a stable subgrade. We start with borings, test the soil, and design the pad with the geotechnical engineer. Where clay is expansive, we specify moisture conditioning, lime treatment or select fill, and we do not place a slab on untested material.

Our mass grading and site development scope includes the pad, haul roads and stormwater controls, while the stormwater and detention scope sizes the basins. A good pad is flat enough to drain, firm enough to pave and arranged so that later phases can attach without rebuilding the first.

After the terminal arrived in Wilmer, the city attracted manufacturers of consumer goods, appliances and medical supplies. Lancaster's largest employers in its 2024 report include a national retailer with 2,125 employees, a freight forwarder, an online retailer and a resale marketplace, and the city includes the Park 20/35 logistics business park. Lancaster Regional Airport, a city-owned reliever field with a 6,502-foot runway, is two miles southeast of the central business district.

These logistics and manufacturing neighbors run warehouse and order systems that depend on dependable networks. For a developer, they are also a source of competition for labor, trucks and materials. Our real estate developers and site owners page explains how we help landowners bring pads to the market, and our Mesquite page covers another rail-served park.

Trucks define the site. Tractor-trailers delivering generators, transformers and chillers are heavier than ordinary traffic, and the access road, the truck court and the entry apron must be built for them. We design pavement sections for the actual axle loads, dowel the joints, and detail the entry so that trailers can turn without climbing curbs.

Our truck courts and access roads scope covers those details. Because logistics neighbors share the same roads, we agree on haul times and routes with the city and with adjacent owners, and we keep the roads clean during construction. A sweeper on site every day is a cheaper investment than a complaint. For a campus with an airport neighbor, Alliance Fort Worth is the natural comparison.

A campus is built in phases that each need power. We set up the first phase so that its utility service, site work and main building can be completed on one schedule, then design the infrastructure for the later phases to connect without interrupting it. Duct bank trunks, drainage structures and roads are often built for the whole campus at once, since they are cheaper to build once than to rebuild.

Procurement of electrical equipment is the critical path. We place orders based on the utility date and keep delivery windows tied to site readiness, not to optimistic calendars. See long-lead equipment procurement for how we track production slots and factory tests.

On a large site, small unit-rate differences become large totals. A dollar per cubic yard of earthwork across a very large pad, or a few inches of added pavement thickness across a truck court, moves the budget by amounts that dwarf most building line items. We therefore spend extra effort on quantities: grading models, pavement takeoffs, drainage structure counts and duct bank lengths are all checked against the civil drawings before the price is released.

Land and utility costs vary widely across the area, so we compare parcels on the full delivered cost of readiness: grade, drainage, roads and power. A lower land price loses its advantage if the feeder route is long. Our electrical duct banks and service entrances page explains the feeder estimate, and our utilities and power developers page covers the yard work we do for the utility side.

Mass grading creates dust and mud, and both reach public roads. We install stabilized construction entrances, wash or sweep trucks leaving the site, use water trucks on haul roads and keep a street sweeper on call. Stormwater controls such as silt fence, inlet protection and sediment basins are installed before earthwork begins and inspected after rain.

Equipment operators work around large machines and trucks, so we use spotters, back-up alarms, separated pedestrian paths and clear communication on radios. Heat and lightning plans apply to every shift. When a storm closes the site, a re-entry checklist verifies that excavations, shoring and temporary power are safe before work resumes.

Tell us the acreage, the load and the date. We will respond with a grading concept, a road and drainage plan and a phased schedule.

How do you decide the size of the first pad?

We size it from the building program for the first phase plus the infrastructure that must be built for all phases. We then check that later phases can attach without disturbing the first, and we show the owner the cost of building extra capacity now against doing it later.

What soil treatments are used under slabs?

The treatment depends on borings and lab tests. Options include moisture conditioning, lime or cement treatment, select fill and drilled piers. We follow the geotechnical engineer and do not place a slab on untested clay. The cost of the treatment is carried in the estimate as its own line.

Do rail operations affect construction?

They can. Noise, vibration and crossing delays affect scheduling and layout. We keep sensitive rooms away from rail-facing walls and plan truck routes to avoid crossings. Any work near a rail right-of-way follows the railroad requirements and review times.

Can you work on a spec pad for a developer?

Yes. We can grade, stabilize and utility-prepare pads, with the building shell delivered later when a tenant is signed. We show the developer what a pad should include so that a future tenant does not pay for it twice.

How far is the area from downtown Dallas for crews and deliveries?

Wilmer is about 14 miles south of downtown Dallas and Hutchins about 9 miles, according to the public record. Crews and suppliers from the metro reach the site by I-45, I-20, I-30 and I-35E. We plan start times and deliveries around the freeway peaks, and we keep laydown on site so that trucks do not wait on public roads.
