Industrial Earthwork Services Across Texas and Oklahoma
Industrial sites are measured in acres and in hundreds of thousands of cubic yards, and the slab that goes on them is measured in hundredths of an inch. IRONWILL Earthworks delivers the mass grading, building pads, paving subgrade and drainage that manufacturing plants, distribution centers, cold storage and data centers are built on, across the whole footprint and in the order the program releases it.
Acres, not lots, and the fleet to match
One design surface held across the whole footprint
Truck courts and rail roadbed built to their own specifications
Early pads released while grading continues
At industrial scale, small errors are multiplied by the acre
A tenth of a foot out of tolerance on a small pad is a nuisance. Across a floor slab of several hundred thousand square feet it is thousands of yards of concrete out of place, and it shows up in the numbers the owner will measure. ASTM E1155 quantifies a finished floor's flatness and levelness as FF and FL numbers1, racking, automated storage and forklift traffic are all specified against those numbers, and a slab cannot be flatter than the subgrade beneath it is uniform. Industrial earthwork is the same work as any other site, done at a scale where uniformity matters more than anything else about it.
IRONWILL Earthworks partners with developers, general contractors and industrial owners across Texas and Oklahoma on greenfield builds and expansions. Our crews run GPS-guided equipment, build the whole footprint to one design surface and check grade against it in the field as we go, so the pad under the last column line is built to the same model as the first, and a miss is found the day it happens rather than at the end.
The other constraint is loading. Industrial pavement carries loaded trailers, container handlers and constant truck traffic, and an industrial specification more often calls for modified Proctor compaction: the ASTM D1557 test applies 56,000 foot-pounds per cubic foot, four and a half times the standard effort, with a ten pound rammer dropped eighteen inches2. A subgrade compacted to a percentage of that maximum is denser than a retail parking lot ever sees, and it is proven lift by lift with a nuclear gauge to ASTM D69383.
Earthwork for industrial sites, from the first acre to the last pad
Industrial developments involve very large grading quantities, heavy pavement, deep process utilities and pads that go to different tenants at different times. That is the list of scopes an industrial site actually needs from us.
Balance and haul studied across the whole site before the bid, because on two hundred acres the difference between a balanced site and an imported one is the whole schedule.
Complete clearing of former farmland and pasture, with the fence lines, stock tanks and old foundations that come with it.
Removal of the plant, slabs and rail of a previous industrial use, with the surveys and notices demolition requires done first.
Bulk cut and fill across the whole footprint, with embankment placed in lifts and each lift tested before the next goes on.
Building pads of several acres built to one uniform section, so the slab's flatness numbers are achievable from the first pour to the last1.
Truck courts, trailer storage and fire lanes on the heavier sections the geotechnical report assigns to them, with base placed and tested before paving.
Support for deep pits, dock walls and excavations beside an existing plant, engineered wherever an adjoining structure would be endangered9.
Controls sized for a site that may stay open a year or more, with the SWP3 kept current as phases are released6.
Pad release sequence, haul road plan, testing coordination and the daily production record a phased program runs on.
Every scope also covers the work that does not get its own page: storm drainage structures and their backfill, rough and final grading, stabilization, import and export of material, and the haul roads that let the rest of the site keep moving. On an industrial site it is sequenced around production, because the paving crew cannot start until the base is accepted and the slab cannot start until the pad is.
How a staged industrial site is delivered
Industrial schedules run on production: yards per day, pads released per week, and a paving crew that cannot start until the base is tested and accepted. The earthwork is shaped by what will stand on it, facility by facility.
| Facility | What the earthwork must deliver | What governs it |
|---|---|---|
| Distribution and logistics | One floor slab across hundreds of thousands of square feet with flatness and levelness the owner will measure, and truck courts and trailer storage on the heavy pavement section | ASTM E1155 FF and FL numbers1; the geotechnical report's pavement sections |
| Manufacturing | Equipment pads and pits at different elevations inside one footprint, with process utilities deep beneath them | Federal excavation rules where a cut runs below an adjoining footing9; the report's fill requirements |
| Cold storage | A pad with no soft spot anywhere under a slab that will carry insulation, a heated subfloor and racking to the roof | ASTM E11551; proof rolling over the whole footprint |
| Data centers | Several building pads plus generator and switchgear yards released in sequence, and detention sized for a very large roof | The pad release schedule; the region's iSWM stormwater criteria10 |
| Rail-served sites | A spur roadbed built to the railroad's standard: the top three feet of subgrade at 95 percent of the modified maximum density, moisture within three percent of optimum, every lift tested before the next, proof rolled before subballast | Union Pacific Industrial Track Specifications4; ASTM D15572; ASTM D69383 |
| Any of them, once operating | Yards graded so stormwater from material storage and loading areas is manageable under the owner's own permit | TCEQ Multi-Sector General Permit TXR0500007 |
Safety on a site this size is a production issue as well as a compliance one. Large crews, heavy haul traffic and deep utility work share one footprint, so the plan that keeps them apart exists before the first machine tracks onto the site: utility locations determined and the owners contacted before any excavation is opened, a competent person inspecting every excavation daily and after rain, and haul routes that never cross an active pad9. Dust is regulated as well. Texas prohibits discharging any air contaminant in a concentration and duration that interferes with the normal use and enjoyment of property8, and a two hundred acre grade in August produces exactly that unless the water trucks are running.

Industrial projects we support
We provide earthwork for industrial development across Texas and Oklahoma, whether the project spans several acres or several hundred, and whether it is one building or a park delivered over years.
Two of them carry specifications of their own. A rail-served site's spur is built to the railroad's standard: on a Union Pacific industry track the top three feet of subgrade are compacted to at least 95 percent of the ASTM D1557 maximum density, material below that to 90 percent, moisture is held within three percent of optimum, every lift is tested before the next is placed, and the finished subgrade is proof rolled before subballast goes down4. And once the plant is running, stormwater from its material storage and loading areas may need the owner's own coverage under the state's Multi-Sector General Permit, TXR050000, whose new term begins August 14, 20267. We grade the yards so that permit is easier to keep.
Planning an industrial development?
Send the civil plans, the geotechnical report and the phasing you have in mind. We will come back with earthwork quantities, a pad release sequence, and what the testing and treatment actually add to the schedule.

Industrial earthwork FAQ
What types of industrial projects does IRONWILL Earthworks support?
Manufacturing plants, warehouses, distribution and logistics centers, industrial parks, flex buildings, cold storage, processing plants, data centers, rail-served sites and expansions of existing plants across Texas and Oklahoma.
Can you handle large-scale industrial earthwork?
Yes. Large industrial sites are what our fleet and crews are organized around: bulk grading in the hundreds of thousands of cubic yards, building pads covering several acres, storm systems and phased delivery that releases early pads while grading continues elsewhere. Where a report specifies select material for the pad, TxDOT's Type A embankment, with a liquid limit of 45 or less and a plasticity index of 15 or less, is the kind of definition it usually points to5.
Do you provide complete industrial site preparation?
Yes: clearing, selective demolition, excavation, mass grading, pad preparation, paving subgrade and flexible base, storm drainage, excavation support, erosion control and final grading, as one scope rather than split across subcontractors.
How is an industrial floor slab pad different from a commercial one?
Mostly in uniformity and in the compaction standard. An industrial slab is specified to flatness and levelness numbers under ASTM E11551, and the subgrade has to behave the same at every point beneath it, so the pad usually gets deeper treatment or select fill, proof rolling across the whole footprint rather than spot checks, and compaction measured against the modified Proctor curve rather than the standard one2.
Do you build the truck courts and heavy-duty pavement too?
Yes. Truck courts, trailer parking and fire lanes take the heaviest loading on the site and are prepared to a heavier section than the car park: treated subgrade where the report calls for it, thicker flexible base, and density proven with a nuclear gauge before paving3.
What areas do you serve?
Industrial construction across Texas and Oklahoma from our Dallas base, including Dallas, Fort Worth, Plano, Frisco, McKinney, Allen, Prosper, Celina, Denton, Sherman, Greenville and the surrounding communities.
