Lower Workers’ Comp Premiums: The Safety-Data ROI for GCs

Lower Workers’ Comp Premiums: The Safety-Data ROI for GCs

General contractors lower workers comp premiums by giving carriers verified safety data, because carriers price the risk they can see. SD Builders showed what visible risk control is worth, reporting an EMR drop from 2.1 to 1.2 in twelve months alongside zero false workers’ comp claims. Across projects, BiltOn clients report a 7 percent premium or deductible reduction per project and up to $955K+ saved on a single job, both client-reported.

This guide is for the finance and risk committee: the CFO who signs the renewal, the VP of Risk who manages the broker, and the COO who owns the record behind both. BiltOn is a Safety Intelligence platform that gives enterprise GCs the verified data the whole premium chain runs on.

One scoping note. Our guide to reducing your EMR with verified safety data covers the mod mechanism in depth, so this piece covers the rest of the premium picture: rate structure, carrier credits, program terms, and the board-ready ROI case.

Two terms anchor this guide:

Safety Intelligence: the practice of turning verified, field-captured safety data into risk decisions that hold up to an audit and to an insurance underwriter.

Predictive Safety Management: using verified leading-indicator data to score risk and act before an incident happens, rather than reacting after a claim is filed.

How is a workers’ comp premium actually built?

A workers’ comp premium starts as payroll times a class rate, gets multiplied by your experience modification rate, and then moves with credits, debits, and program structure. Each layer responds to different evidence, which is why premium strategy fails when it only targets one layer.

Plain definitions first. The class rate is the price per $100 of payroll for a given trade. The EMR is the multiplier that compares your losses to expected losses for a contractor your size. Schedule credits are discretionary discounts an underwriter, the person at the carrier who prices your risk, applies when the account looks better than its class.

Timing matters on the second layer. Because EMR is calculated on a rolling three-year basis, today’s discipline shows up in renewal terms 18 to 36 months later. The credits and program layers can move at the very next renewal, which is where verified data earns its fastest return.

What is the 2026 workers’ comp market telling GCs?

The market is soft on rates and hard on severity, and that combination rewards contractors who control claims now. Rate decreases are a market gift that severity can take back one claim at a time.

• Rates keep falling. NCCI’s 2026 State of the Line report put the calendar year 2025 combined ratio at 91 percent, the twelfth straight year of underwriting gains, with net written premium down 0.2 percent.

• Filed rate cuts are compounding. Reporting from Risk & Insurance on the same results notes approved rate filings are expected to cut premiums about 5.0 percent on average through 2026.

• Severity is climbing underneath. The same NCCI data shows lost-time claim frequency fell only 2 percent, a slower decline than the long-term average, while medical and indemnity severity each rose 4 percent.

• Medical inflation is structural. The Enlyte Envision 2026 trends report shows injured workers receiving more services per claim, with moves like Florida’s 2025 fee schedule change lifting recommended payments 21.1 percent per bill.

• Buyers have negotiating room. Alera Group’s 2026 Property and Casualty Market Outlook expects average workers’ comp rate decreases and describes underwriting as increasingly flexible for well-presented risks.

Read those together and the strategy writes itself. Every GC gets some of the rate tailwind. Only GCs who can prove low claim frequency and defend questionable claims keep it when severity hits their loss runs.

Where does verified safety data create premium leverage?

Verified safety data creates leverage at four points in the chain: fewer claims, defensible claims, underwriter credits, and better program structure. Each lever moves a different line in the premium build.

Prevention is the first lever. Leading-indicator data, like daily pre-task plan completion and verified credential checks, catches risk before it becomes a claim, and BiltOn clients report a 30 percent average EMR reduction, client-reported. We covered why incident counts alone cannot do this in tracking lagging indicators is not a safety strategy.

Defense is the second. Rabsky Group calculated that fighting one false injury claim without verified records cost $35,000 or more in investigation, legal, and deductible costs, client-reported, and BiltOn clients report roughly three fraudulent claims prevented per project. Claims that never reach your loss runs never reach your EMR.

The third lever is the underwriter’s pen. Gallagher’s construction market update for late 2025 into 2026 reports that firms with strong documentation, training, and oversight can earn preferred pricing and retention terms, and cites contractors using predictive analytics cutting incidents by up to 20 percent. Carriers themselves are funding the shift: Zurich’s program with Arrowsight, announced in November 2025 and separate from BiltOn’s customer base, reported a greater than 50 percent reduction in workers’ comp claim frequency in its pilot cohort.

Structure is the fourth. Contractors are moving into large deductible and captive programs to retain underwriting profit, and the entry ticket is credible loss data, because you cannot responsibly retain risk you cannot measure. Verified field data is what makes a deductible or captive feasibility study defensible.

What does decision-grade data earn with your broker and underwriter?

Decision-grade data earns credibility, and credibility is the currency of every renewal negotiation. Decision-grade data means records an underwriter can act on without discounting them for doubt: identity-verified, timestamped, complete, and consistent across every site in the portfolio.

The renewal submission is where this shows up. A standard submission carries loss runs, payroll, and a safety manual, while a submission backed by Safety Intelligence adds leading-indicator evidence: pre-task plan completion rates, verified headcounts, observation time-to-resolve, and access records for every worker. We described that gap in how Safety Intelligence turns jobsite data into lower insurance costs, and underwriters are already repricing it, as we covered in why carriers are repricing GCs.

Archstone’s experience shows the tone of the conversation changing. As Michael Drumm, Head of Safety at Archstone, put it: “When insurance comes to do a walk, I show them the platform. They love it. No binders. No guessing. Just a clean, searchable record.” An underwriter who trusts the record prices the account, not the class average.

Think of verified safety data as the telematics for the jobsite. The old way rewards you for not having an accident three years ago, and the new way rewards you for preventing an accident today and proving it at renewal.

What does the ROI math look like for the board?

The board case rests on one worked example and three client-reported multipliers. Start with an enterprise GC running $120 million in annual payroll at a blended class rate of $7.00 per $100 of payroll.

That mod swing alone is worth about $2.5 million a year, before schedule credits and program restructuring. Layer on the client-reported BiltOn figures: a 7 percent premium or deductible reduction per project, up to $955K+ saved on a single project, and a 6 to 9x median ROI. SD Builders is the live version of the math, with its EMR falling from 2.1 to 1.2 in twelve months, client-reported by COO Ryan Goddard.

Present the timeline honestly and the board will trust the rest. Credits and program terms can move at the next renewal, and the mod compounds over the following cycles as the three-year window refills with clean years. Total cost of risk, meaning premiums plus retained losses, claim administration, and the bids a high EMR locks you out of, falls across the whole period.

How does BiltOn give risk leaders that data?

BiltOn is the verified layer between the field and the carrier, turning daily jobsite activity into decision-grade records. The platform verifies every worker with 3D facial verification, ties pre-task plans and observations to those identities, and syncs two ways with Procore and Autodesk, both partners, so safety records stay connected to project records.

For the risk team, the output is a portfolio-wide record that answers underwriter questions in minutes. Consistency is what carriers reward, a point we documented in why consistent safety platform adoption decides your construction insurance premiums, and verified identity records are what let clients like Rabsky disprove a false injury claim before it reached the loss record.

Customer proof point: SD Builders. SD Builders took its EMR from 2.1 to 1.2 in twelve months and recorded zero false workers’ comp claims over the period, results reported by COO Ryan Goddard. Verified identity and access control kept fraudulent claims off the loss runs that set the mod, and the cleaner mod now prices every renewal and every bid the firm submits.

As Omer Slavin, Co-Founder and CEO of BiltOn, puts it: “See every site, verify every worker, prove every record.”

Executive takeaway

A workers’ comp premium is built in layers, payroll times class rate times EMR plus credits and program structure, and verified safety data moves all four. NCCI’s 2026 State of the Line shows a 91 percent combined ratio and roughly 5 percent average filed rate cuts, but medical and indemnity severity each rose 4 percent. In the worked example, moving the EMR from 1.2 to 0.9 on $120M of payroll is worth about $2.52 million a year before credits. BiltOn clients report a 30 percent average EMR reduction, a 7 percent premium or deductible reduction per project, and a 6 to 9x median ROI, all client-reported. SD Builders cut its EMR from 2.1 to 1.2 in twelve months with zero false claims, and the rolling three-year mod window keeps that discipline paying through 2029 renewals.

Frequently Asked Questions

1. How much can a GC save on workers’ comp with better safety data?

The swing depends on payroll size and starting EMR. On $120M of payroll, moving the EMR from 1.2 to 0.9 saves about $2.52 million a year before schedule credits. BiltOn clients report a 7 percent premium or deductible reduction per project and up to $955K+ saved on a single project, client-reported.

2. How long does it take for safety data to lower premiums?

Schedule credits and program terms can improve at the next renewal once the underwriter sees credible data. The EMR moves more slowly because it is calculated on a rolling three-year basis, so today’s discipline shows up in renewal terms 18 to 36 months later. The savings compound as clean years replace bad ones in the window.

3. What is total cost of risk?

Total cost of risk is every dollar risk removes from the business, not just the premium. It includes premiums, retained losses inside deductibles, claim administration and legal costs, collateral, and the margin lost when a high EMR takes you off an owner’s bid list. Verified safety data lowers several of those lines at once.
