Warehouse and logistics builds in south Dallas County are large, open and long, so a single bank at the gate is rarely enough. Plan several banks by work area, a handwash station at each, a count that follows the headcount in each phase and a servicing routine built for dust, heat and distance.
Key takeaways
- The Dallas Logistics Hub is described by its developer and lead consultant as a 6,000-acre master-planned site across Dallas, Hutchins, Lancaster and Wilmer, with up to 60 million square feet planned over 20 to 30 years.
- Long distances across open ground mean a single bank at the gate costs crews time, so plan several banks near the work with a handwash station at each.
- The crew and the count change with each phase, from site work and slab to walls, roof and fit-out, so review the number of units at the start of every phase.
- Dust, heat and dry or wet ground change how often units need service and how a truck reaches them, so agree the schedule and the haul route with the provider.
- OSHA 29 CFR 1926.51 sets one toilet for a crew of 20 or fewer and adds more as the headcount grows; the site manager confirms the number and this site names no project.
What is the Dallas Logistics Hub?
It is a master-planned logistics area described by its developer and lead consultant as 6,000 acres spanning Dallas, Hutchins, Lancaster and Wilmer, with up to 60 million square feet of distribution and manufacturing space planned over 20 to 30 years. For a toilet rental, it means long-running building on open ground.
In Wilmer, a first phase of 255 acres was reported as two buildings of 2.1 million square feet, growing to 4.5 million square feet in four buildings. No groundbreaking year is given here, because the reports used do not state one, and this guide names no builder or tenant.
What matters for sanitation is the shape of the work. Buildings that size need crews of hundreds over many months, and a program spread over decades means a steady stream of new sites rather than a single project that ends. A provider that serves the area plans routes and stock for that rhythm.
A reader might ask why a guide about toilets spends time on acreage. The answer is that distance is the main variable in sanitation on a large site. The number of toilets is set by the crew, but their usefulness is set by where they stand, and a count that looks right on paper can fail when the nearest unit is a quarter mile from the work.
How do phases change the toilet count?
The crew changes with the work. Site work and grading use equipment operators, the slab brings finishers, walls and roof bring many trades at once and fit-out brings electricians and installers. Count the peak crew in each phase and review the number of units at the start of each.
OSHA 29 CFR 1926.51 sets one toilet for a crew of 20 or fewer and adds more as the headcount grows under the standard's table. The site manager reads the requirement from the standard and applies it to the peak crew. This site cannot say that any number meets a code.
The table below lays out the phases and what changes for sanitation. It gives directions rather than counts, since the real counts depend on each site's crew.
Planning by phase also helps with budgets. A site manager who knows that the slab phase needs more units for six weeks can ask the provider for a short-term addition rather than carry extra units through the whole build. Ask whether the provider can add units for a phase and take them back afterward.
| Phase | Typical change | What to ask the provider |
|---|---|---|
| Site work and grading | Equipment operators, dust, moving ground | Where can banks stand that will not be graded soon? |
| Slab and foundation | Large finishing crews, long days in heat | Can you add units and handwashing for pour days? |
| Walls and roof | Many trades on the same day | How fast can you add a bank? |
| Fit-out and finishing | Specialist trades working inside | Do banks need to move closer to the building? |
| Handover | Units no longer needed | When can you collect, and what notice do you need? |
Where should banks go on a big site?
Near the work, on firm higher ground, away from haul roads and future trenches, with a route for the service truck. A single bank at the gate may be far from the work, and walking costs time. Several banks, each with a handwash station, serve crews better.
Ask the foreman where water will run after rain, where the next excavation is and which roads carry heavy traffic. Mark each bank on the site plan, number it and give the plan to the provider so the driver places units where you intended.
When work moves, banks move. Only the provider moves them. Tell it where and when, and expect a charge per move. The delivery page explains the access the driver needs.
Think about the driver's view. A service truck is long, heavy and slow to turn. It needs a straight approach to each bank, a firm surface and room to back out. If the only way in is a narrow lane between stockpiles, the driver may skip the unit. Walk the route in a pickup before you finalise the bank positions.
- Near the work
- Firm higher ground
- Off haul roads
- Numbered on the site plan
How do dust and heat change the plan?
Dust gets into latches, pumps and towels, and heat raises use and odour. On open ground with no shade, both are strong. Ask the provider for more frequent service in summer, shade over banks and handwash stations with large tanks and a cleaning plan.
Press reports put an ordinary Dallas year at roughly 20 days at 100 F or hotter at DFW Airport, and the National Weather Service records many more in the hottest years. A crew working a bare slab in July is exposed to all of it. The heat guide explains what to ask for.
Rain brings the opposite problem. A dry haul road can turn to mud, and a truck may not reach a bank. Agree an alternative access route with the provider and the foreman.
Where a site has a water truck damping the dust, tell the provider the timing. Wet roads help the dust but are slick, and a service truck may need to wait. Agree a time for the visit that suits both.
What should the site contract say about sanitation?
It should say who supplies the facilities, how many units are on site for each phase, who the provider is and who calls it. On a multi-employer site, a subcontractor who assumes another trade has handled sanitation can leave a crew without a toilet. Write it down at the start.
Include handwashing in the same clause. A site with toilets but no handwashing has missed half the requirement, and the fix is a call to the provider, not a new contract.
Keep the provider's quote and the servicing schedule with the site records. The construction requirements guide explains the file to keep.
Think about who else uses the toilets. Delivery drivers, inspectors, surveyors and the owner's representatives all pass through a large site. A visitor bank by the gate, with an accessible unit and a handwash station, keeps them from using the crew's units and gives the site a clean face to visitors.
How should servicing be set up on a large site?
Agree the days, the route and the access points. A truck servicing banks across acres needs a plan: which bank first, where it can turn and which gate it uses. Ask the provider to confirm in writing and to say how it will handle an extra visit.
Large sites have security and gate rules. Tell the provider about passes, hours and speed limits so that the driver arrives with the right papers.
A weekly visit may be enough for a quiet bank and not enough for a busy one. Ask the provider to set a schedule per bank. The servicing page explains what a visit includes.
Because crews are large, one missed service can affect hundreds of people. Ask the provider what its backup is. If a truck breaks down, does another take the route? If the provider cannot say, ask for a second route plan, such as extra capacity at the busiest banks.
How does a logistics build differ from other jobs?
It is bigger, flatter and longer. Distances are greater, shade is scarcer, the programme runs over years and cranes and trucks fill the site. Units must stay out of the way of heavy traffic, and the provider must be able to reach them without blocking it.
Smaller sites can get by with a gate bank and a trailer. On a logistics site the same plan fails because of distance. The principle is the same, to put the toilet where the work is, but the scale changes the number of banks.
If you are comparing quotes, check how many banks and stops each includes, because each stop adds a delivery and a service.
What about the end of a phase or the whole build?
Tell the provider the last day of use and ask for the pickup in writing. Units on a finished site still count as on rental, and an owner or tenant who finds them left behind may complain. Arrange a final service so that the units leave clean.
When a building gets its own plumbing, the crew may switch to its fixtures. Check with the owner and the general contractor that the building's restrooms are approved for use before you give up the units.
Keep a record of the pickup. A photo of the empty pad and a note of the date settle any later question about when the rental ended.

Frequently asked questions
Does this guide name a project or a builder?
No. It describes the area and the kind of work from public reports, and it names no project, builder or tenant. This line connects callers with a provider and does not say who works on which site.
How many units does a large warehouse build need?
It follows the peak crew in each phase. OSHA 29 CFR 1926.51 sets one toilet for a crew of 20 or fewer and more as the headcount grows. The site manager confirms the number, and the provider can tell you what a given crew usually needs.
Can banks be moved as work progresses?
Yes, through the provider. Give it the new location and the date, and ask what a move costs and how much notice it needs.
Do I need a handwash station at every bank?
It is a good practice on large sites, because OSHA expects handwashing near toilets and a long walk discourages it. Ask the provider about tank size and refills.
What if the build runs for years?
Ask for a long-term arrangement and a review of units and servicing at set intervals. The long-term rental page explains how.
