Hyperscale Data Center Boom Tests Contractor Safety Systems at Scale

Hyperscale Data Center Boom Tests Contractor Safety Systems at Scale

Hyperscale data center construction is moving so fast that even large, well-resourced general contractors are struggling to keep their safety programs from cracking under the pace, according to Engineering News-Record. The publication’s reporting on JE Dunn Construction and Caterpillar Safety Services shows a sector where billing volume, worker headcount, and subcontractor counts have outgrown the safety infrastructure built for conventional commercial jobs.

Background

JE Dunn senior vice president Marc Hutson told ENR that data center work runs at a scale that breaks old safety models. He compared it to a typical $200 million hospital job, which might run $15 million a month in construction billings. A hyperscale data center project, by contrast, can post $60 million to $70 million in monthly work in place. “If you approach that with an old school mentality, you will continue to come up short on preventing injuries,” Hutson said.

That volume brought JE Dunn back to Caterpillar Safety Services, a standalone consultancy inside the equipment maker that is not tied to Caterpillar equipment sales or rentals. Justin Ganschow, the unit’s business development manager, told ENR that conversations with contractors representing six of the largest data center companies revealed a consistent pattern: rising “error precursors,” near-misses, miscommunications, and fatigue-driven mistakes that don’t always show up as recordable incidents but often precede serious injuries.

Ganschow also pointed to a disconnect between owners and contractors on what safety should mean. Some data center owners focus narrowly on recordable injury rates (RIR), he said, while missing the more serious hazards captured under the industry’s “stuff that can kill you” (STCKY) framework. He described one instance where a contractor spent roughly 20 minutes discussing safety with an owner and over two hours on schedule, reinforcing the sense among crews that safety reviews are a box-checking exercise. A recent ABC survey cited in the ENR report found that contractors with over $100 million in revenue are capturing the largest share of data center work, meaning the biggest firms are also the ones absorbing the most strain.

Analysis

The core problem here isn’t a lack of safety commitment, it’s span of control. Ganschow told ENR that GCs are running a safety perception survey across 90 subcontractors on a single project, which is a scale of coordination that most commercial safety programs were never designed to handle. When a GC is stacking multiple hyperscaler contracts at two to three times its normal project volume, the informal channels that catch small problems before they become incidents, a foreman noticing fatigue, a super flagging a near-miss, start to break down simply because there aren’t enough eyes per worker.

This is why the fix JE Dunn adopted isn’t a new app or a stricter penalty system, it’s pushing safety ownership down into operations leadership. Hutson’s point that “if operations leadership is not bought in on safety, you’re gonna have safety cops” without real authority is the crux of the story. Caterpillar’s model requires superintendents, many of whom came up through the trades, to be the ones enforcing safety on the ground rather than outsourcing it to a separate compliance function. JE Dunn is now requiring craft workers to complete a day-long safety course and superintendents a three-day course before they can work on its data center projects, and Hutson plans to extend that requirement across all of JE Dunn’s data center work this year.

The other notable shift is the “Speak Up and Listen Up” approach, which asks workers to rate their bosses on safety and surfaces leadership lapses through direct interviews rather than paperwork audits. Combined with root cause analysis training for frontline supervisors and a separate session for senior project managers on why people make mistakes under pressure, the program is built around behavioral data, not just incident logs.

Hutson’s closing point to ENR, that GCs are sharing safety approaches openly because “we don’t really have trade secrets when it comes to safety,” suggests this kind of cross-company collaboration on safety standards may become more common as hyperscaler campuses keep stacking multiple GCs and thousands of transient workers on the same site.

What It Means for Subcontractors

• Expect GCs bidding hyperscale data center packages to require standardized safety onboarding, JE Dunn is now mandating a full day of training for craft workers and three days for superintendents before badge access, so build that time into labor scheduling and bid pricing.
• If your crews are cycling across multiple data center campuses, prepare for safety perception surveys and worker interviews as part of GC oversight. Ganschow described a GC running these surveys across 90 subcontractors on one job, meaning your foremen should expect direct questions about leadership behavior, not just incident paperwork.
• Watch for owners who emphasize recordable injury rate metrics over near-miss reporting. Ganschow flagged this as a source of “mixed messages” that push crews toward treating safety reviews as a formality, so subs should document near-misses and error precursors internally regardless of what the owner’s dashboard tracks.
• Trades most exposed to the fatigue and pace issues described, electrical, mechanical, and general labor crews running compressed schedules, should push for root cause analysis training for frontline supervisors, a practice Caterpillar Safety Services is building into its data center programs.
• Firms with over $100 million in revenue are capturing the largest share of hyperscale data center work per the ABC survey cited by ENR, so smaller subs should confirm which GC tier they’re working under and whether that GC has the safety program capacity to manage add-on subcontractor layers without gaps.
