How AI Turns Subcontractor Safety Data Into Risk Visibility

Data center work is growing faster than almost any other part of construction, and its jobsites are some of the most crowded. U.S. construction spending fell 3.8% year over year in July 2026, according to the Census Bureau. Data center construction rose 57.2% over the same stretch, according to an analysis by the National Association of Home Builders. That split puts more of the industry’s work—and more of its risk—onto fewer, larger jobs that general contractors run.

Those jobs tend to carry 40 to 50-plus subcontractors, thin crews and schedules with little slack. General contractors answer for safety across all of it, and a missed hazard carries a steeper price than it did a few years ago. One slip-up and damaged equipment or injured workers can set a project behind schedule, costing millions of dollars in material, insurance and liability.

Together, those pressures turn subcontractor safety management into a business risk control, and the data coming off the front line is how general contractors manage it.

Where Is the Construction Boom Happening?

Data centers now account for more than 60% of office construction spending, making them the main driver of the current boom.

Overall spending figures can hide how uneven the market has become. Census data suggests a slowdown—total construction spending in July 2026 ran at a seasonally adjusted annual rate of about $2.16 trillion, its lowest level since October 2023. However, data center work kept climbing as the rest of the industry cooled. These megaprojects are hot right now, but not every organization that dives in to this gold rush is ready for the logistical challenges and financial pressures that come along with the opportunity.

Concentrated demand in the space changes the shape of the work general contractors take on:

• More trades working the same footprint at the same time, especially in the push toward commissioning
• Schedules tied to an owner’s go-live date, with little room to absorb delays
• A larger share of a firm’s revenue and exposure riding on a handful of projects
• Construction often continuing while commissioning teams test and energize electrical systems nearby

Engineering News-Record reported in July 2026 that contractors on hyperscale data center projects can struggle to keep one safety culture intact across dozens of subcontractors and thousands of workers.

Each of those shifts raises the stakes on how clearly a general contractor sees what’s happening across every trade on site. A blind spot on one megaproject carries more financial and legal weight when so much of the business depends on that job.

How the Labor Shortage Changes Who’s on Your Jobsite

On top of a data center boom, construction is also facing a serious labor shortage. Ninety-two percent of contractors struggle to hire, so crews tend to turn over fast and last month’s orientation may not cover today’s crew.

The Associated General Contractors of America reported in its 2025 Workforce Survey that 92% of firms have trouble filling open positions. Forty-five percent reported project delays tied to worker shortages, either in their own workforce or among their subcontractors.

The same survey points to churn among new hires:

• 57% of firms say candidates lack the skills or qualifications for the job
• 48% say new hires fail to show up or quit soon after starting

Data center projects tend to pull skilled labor away from other work, and their schedules leave little time to re-orient each new crew. Overlapping trades in tight spaces add strain of their own. Trade stacking puts several crews in one work zone, and traditional safety programs tend to break down on megajobsites under that pressure.

Who Is Responsible for Subcontractor Safety on a Multi-Employer Jobsite?

OSHA’s multi-employer citation policy lets the agency cite a general contractor that controls a site for hazards affecting subcontractor workers.

Contracted workers carry a disproportionate share of the risk on construction sites. The Center for Construction Research and Training found that contracted workers accounted for 52% of all construction fatalities and 62.7% of fatal falls from 2011 to 2022. CPWR counts a worker as contracted when one company employs them and another company holds overall responsibility for the site.

OSHA‘s citation policy connects those numbers to the general contractor. It sorts the employers on a site into four roles:

• Creating employer: caused the hazardous condition
• Exposing employer: has workers exposed to the hazard
• Correcting employer: holds responsibility for fixing it
• Controlling employer: has general supervisory authority over the site, a role that usually belongs to the general contractor

OSHA expects a controlling employer to exercise reasonable care to prevent and detect violations, even when its own employees face no exposure. That standard shifts the question after an incident to what the general contractor knew and when it knew it.

Safety directives spell out how OSHA inspectors judge reasonable care. The right inspection frequency depends on the scale of the project, the pace of the work and what the general contractor knows about each subcontractor’s safety history and expertise. Inspectors then look at whether the controlling employer:

• Conducted periodic inspections at an appropriate frequency
• Put an effective system in place for correcting hazards promptly
• Enforced subcontractor compliance through a graduated system of enforcement and follow-up inspections

The obligation goes beyond finding hazards. One example in the directive describes a general contractor that found fall protection violations during its inspections and still drew a citation, because it lacked a graduated system to make the subcontractor fix them.

Each of those questions has a data trail behind it. Observations document how often someone walked the site, corrective actions record how quickly hazards closed and a subcontractor’s history over time shows whether enforcement escalated when problems repeated. The directive also names a consistently high level of compliance as the strongest sign that a subcontractor’s own safety effort works, and steady frontline data is how a general contractor can show it.

A general contractor that can show it identified hazards across its subcontractors and followed through on them stands on firmer ground with regulators, insurers and juries. Strong incident management records help that case hold up after the fact.

What a Missed Hazard Costs General Contractors Now

Megaprojects offer a massive profit opportunity, but they come with high risk that can affect insurance premiums if an organization has a spotty track record in safety. Insurance industry analysts estimate litigation trends added $231.6 billion to $281.2 billion to U.S. liability losses from 2015 to 2024.

The Insurance Information Institute and the Casualty Actuarial Society attribute that increase to what they call legal system abuse and related litigation trends, over and above normal economic inflation. Two lines of coverage general contractors rely on carry a large share of it:

• General liability: an estimated $83.4 billion to $103.3 billion in added losses
• Commercial auto: an estimated $52.0 billion to $70.8 billion in added losses

Commercial auto exposure comes with the job for most general contractors. Pickup fleets, material deliveries and equipment hauls keep vehicles moving in and around active sites, and a single serious crash can turn into a multimillion-dollar claim.

Insurers call the broader pattern social inflation: claim costs rising faster than the broader economy because of larger jury awards, more litigation and shifting attitudes about corporate responsibility. Nuclear verdicts, meaning jury awards of $10 million or more, are one of the clearest signs of it. Marathon Strategies counted 135 of them against corporations in 2024, totaling $31.3 billion. Construction and engineering drew $2 billion of that total, the fourth-highest of any industry, according to Risk & Insurance.

The pressure shows up in pricing. Marsh reported that U.S. casualty insurance rates rose 7% in the second quarter of 2026, while global commercial rates fell 6%.

Underwriters tend to price that exposure based on how well a contractor manages risk, and they increasingly want to see the evidence. A safety record of documented hazards and closed-out fixes gives a general contractor something concrete to put in front of them. The claims history behind that record also drives a contractor’s experience modification rate, which can shape bid eligibility on large projects.

Why Subcontractor Safety Management Runs on Frontline Data

Frontline data, like pre-task plans, observations and near-miss reports, shows a general contractor where hazards sit across every subcontractor.

Those records are leading indicators: signals that a hazard exists before anyone gets hurt. Lagging indicators, like recordable injuries and lost-time cases, arrive after the harm. Those numbers tend to trail too far behind a megaproject to guide it. A recordable rate can take weeks or months to show a trend, and by then the crew involved may have rotated off the job.

Early safety planning tends to show up in injury rates, and that planning depends on knowing where hazards sit. Dodge Construction Network and CPWR’s 2026 safety management study found that 80% of firms that involve a safety director in preconstruction planning report reduced recordable injury rates, compared with 63% of firms that don’t. Only 43% of firms bring one in.

Conversations with general contractors tend to circle back to two concerns. Trades often push back on new safety requirements, since each one can feel like another form between the crew and the work. Owners and insurers also want evidence of the due diligence behind a safety program and a binder of signed forms rarely gives them enough of it. Both concerns point to the same need: safety data that crews will submit and leadership can put to use.

Capture It Consistently Across Every Trade

Every subcontractor tends to bring its own forms, habits and standards for what a complete PTP looks like. A general contractor gets the clearest picture when those submissions come in through the same channels and carry comparable detail.

Simpler capture helps on both counts. Crews tend to submit more often—and in more detail—when they can snap a photo of a paper PTP or speak an observation aloud. A quality score on each plan then flags the ones that leave hazards uncovered.

Rank It So the Right Hazard Gets Attention First

A jobsite with hundreds of subcontractors can produce more safety records in a day than any team can review in a reasonable timeframe. That’s thousands of documents, which results in a ton of data but very little clarity. Using digital tools to rank those records by hazard severity and recent activity on each job gives a safety leader a clear starting point.

Prioritizing severity matters most here. A missing guardrail on an elevated deck and an expired fire extinguisher tag both belong on someone’s list, and the guardrail carries far higher stakes, since falls have long ranked among the deadliest hazards on a jobsite. A ranked list puts that fall exposure in front of a superintendent first, so the fix can happen before the crew climbs.

Close the Loop and Keep the Record

A flagged hazard protects no one until someone fixes it and documents the fix. A corrective action that links to the original submission and carries a closing time stamp can serve as evidence of reasonable care. A corrective action plan keeps that follow-through and accountability consistent across every subcontractor.

What Ranked Frontline Data Looks Like in Practice

Ranked frontline data turns thousands of daily safety submissions into a short, prioritized list of hazards, each paired with a specific fix.

Here’s how that works, using Safety Mojo’s Risk Feed Dashboard as an example. It reviews the last 10 days of safety submissions and lists the top items that need your attention, in priority order. Those submissions include the records crews already file: pre-task plans, observations, permit requests, incident reports and near-miss reports.

Risk Feed weighs each new submission against three factors:

• How serious the hazard is under OSHA standards
• What’s happened recently on that specific job
• The priorities the safety team sets

The list updates in real time. Each item explains why Risk Feed flagged it, what’s deficient and the best-practice fix, with a link back to the original submission. Strong submissions can earn a spot too, which gives supervisors a reason to recognize crews doing good work.

Acting on the list also builds the record. A safety manager who opens the feed, sends a foreman or superintendent to close a flagged fall hazard and logs the corrective action in Safety Mojo creates a time-stamped record of that fix. The same record can later show a regulator, insurer or jury that the general contractor identified the gap and closed it.

Risk Feed ranks what crews submit, so the quality of those submissions matters. Safety Mojo’s Flex PTP reads pre-task plans and permit requests in the formats crews already use, including paper, whiteboards, PDFs and voice, then scores each plan against a rubric the safety team sets. Conversational Forms lets workers submit observations and incident reports by talking, in English or Spanish, and prompts for details they leave out.

Safety Mojo’s Contractor Scorecard adds a subcontractor-level view, giving each trade a current safety score built on leading and lagging indicators.

Where General Contractors Go From Here

The data center boom looks set to keep concentrating work, crews and liability on fewer jobs. General contractors that capture safety data consistently across every subcontractor, rank it so the right hazard gets attention first and document every fix put themselves in a stronger position with owners, insurers and regulators.
