The United States had 4,287 data centers as of May 2026, and 10 states hold 59% of them. Virginia leads with 603, or 14.1% of the national total. Texas is second with 461. Those numbers come from an AM Best analysis reported by Risk & Insurance, and construction is not slowing.
Behind each of those buildings is a construction workforce that runs from the hundreds into the thousands. Those crews arrive long before the first server is installed and leave long before the ribbon is cut. Schedules are compressed, hazards are unusual, and the site is often nowhere near a hospital.
Which raises a question many general contractors are answering for the first time: how do you pick a medical provider for a job like this? What actually separates one from another?
Why data center builds break the standard occupational health model
Delay is unusually expensive here. AM Best notes that data center construction timelines are often compressed because a completed facility can start generating revenue quickly, which means even modest delays carry high costs. Send a worker to an urgent care 25 minutes away, and you have not just paid for a medical visit; you have lost half a shift from a trade that was on the critical path.
The workforce is temporary, and the site is often isolated. Crews are often left to handle medical needs in places with limited or inconsistent access. Rural land is cheap, and power is available, which is exactly why these campuses get built there.
The hazard mix is its own thing. High-voltage electrical work, heavy rigging of servers, and heat exposure in the southern corridors where much of this construction has landed. Add one more wrinkle that is specific to data centers: builds are often phased, and parts of a facility can go live with running servers before the project is finished. Your crews may be working alongside energized equipment months before turnover.
Questions to ask before you sign
1. Can they staff your peak, and scale back down?
A hyperscale campus can need a full clinic for years. A smaller edge build may need a few months of part-time coverage. Ask what the staffing plan looks like at peak headcount, and then ask the harder version: what happens to your rate when headcount drops 60% during commissioning? Get the answer before you sign, not when you are trying to demobilize.
2. How is the work priced, and does the price move when injuries do?
This is the biggest cost-predictability question in the whole evaluation. Some providers bill per encounter while others bill for time on-site. That logic matters more than the vendor, because if your provider earns more when your people get hurt, the incentives are pointed the wrong way. Ask for the pricing model in writing.
3. What share of cases do they close on-site?
This number determines whether the clinic pays for itself, and it is the easiest thing to benchmark. Ask every provider you are considering for their number, plus the period it covers. A provider who tracks this will hand it over.
4. Who makes the first aid versus recordable call?
Your Total Recordable Incident Rate (TRIR) is largely decided by this judgment, case by case, for the life of the project. On-site medical teams can give real-time guidance on recordables versus first aid as part of compliance support. Of course, that guidance is only as good as the clinician making it.
That being said, be sure to ask:
- Who makes the determination
- What their credentials are
- How it gets documented
- Whether the provider will stand behind the call in an audit
If you want a refresher on where the line actually sits, we have a full guide on how Occupational Safety and Health Administration (OSHA) recordability is actually determined.
5. What do they do before anyone gets hurt?
Treatment is the visible part of the job, but prevention is where the numbers really move. Ask what the provider handles on-site rather than sending people off-site for activities like:
- Pre-employment screening
- Medical clearances
- Respirator evaluations
- Drug and alcohol testing
- Vaccinations
Then ask about the daily work. Think hydration/heat protocols, ergonomic coaching for repetitive tasks, or stretch and flex programs that get crews moving before the shift instead of treating strains after it.
6. How fast can they actually mobilize?
You need a benchmark to hold vendors against. Generally, a month is a reasonable bar. Ask for a mobilization timeline in the contract with dates attached.
7. What will you actually see, month to month?
General contractors on these projects answer to a lot of people. As such, you'll want to ask what reporting comes standard, whether that means incident logs, screening counts, compliance documentation, or portal access for your safety team.
Look for specificity here, all the way down to individual screening and immunization totals. That level of detail is the standard to hold a vendor to, because it is only possible if the underlying tracking is real.
The question most proposals never ask
Every provider in this market sells to the employer. Cost per case, recordables avoided, claims reduced. Those are the right questions for a procurement file, yet almost nobody publishes what the workers think.
That's a gap worth closing, because on a union job with high turnover, crew confidence in the clinic is not a soft metric. If your team trusts the clinic, they report early, small things stay small, and they come back for the next phase. If they don't trust it, they work hurt, and you find out later. When you evaluate providers, ask whether they survey patients at all, then ask to see the survey itself.
At Mobile Medical Corporation, we ask. Since March 2023, we've surveyed 331 workers across 34 projects about the care they received in our clinics - because a clinic only works if the crew is willing to walk through the door.
Power your data center build with MMC
We've spent more than a decade on technology projects, and that work is now the largest part of all construction sectors we serve. Because these builds run multi-year and multi-phase, MMC staffs Data Center Health Care Specialists who work directly with your site safety team - so the standard you set at groundbreaking is the same one in place at turnover.
