Most contractors focus on incident prevention to lower their EMR — and they’re only half right. The Arthur J. Gallagher study of eMOD users found that the companies achieving the steepest experience modification rate reductions weren’t the ones that added more safety rules. They were the ones that changed behavior before incidents happened.
That’s the meaningful distinction. Here’s what the data shows.
What Is EMR and Why Does It Control Your Insurance Costs?
Your experience modification rate is a multiplier applied to your base workers’ compensation premium. An EMR of 1.0 means you pay the industry average. Drop it to 0.85 and you’re paying 15% less. Climb to 1.15 and you’re paying 15% more — and increasingly, you’re also getting screened out of GC prequalification lists before the bid process even starts.
The modifier is calculated by the National Council on Compensation Insurance (NCCI) using your claims history over the prior three years, excluding the most recent policy year. That lag creates a frustrating reality: the work you do on safety today won’t show up in your EMR for 12–18 months. Which means contractors who want to lower their experience modification rate need to start now.
What the Arthur J. Gallagher Study Actually Found
An independent Arthur J. Gallagher study of an ENR Top 400 contractor using eMOD Safety documented a 24.5% EMR reduction, 45.3% TRIR decrease, and 46.3% drop in workers’ compensation premiums over three years of deployment — compared against a five-year pre-eMOD baseline.
The study, published in 2024, examined a general contractor handling more than $600 million in annual construction volume. The contractor had a better-than-average safety record before eMOD — which matters, because it rules out the easy explanation that a poorly run program got fixed.
The results weren’t incremental.
- Experience Modification Rate (EMR): 24.5% reduction
- Total Recordable Incident Rate (TRIR): 45.3% decrease
- Days Away, Restricted, or Transferred (DART): 50.9% decrease
- Workers’ Compensation Premiums: 46.3% decrease
- Administrative hours recovered: 884 hours per year for the Safety Admin; 1,300 hours per year for the Safety Officer
As Arthur J. Gallagher Executive Mathew Kalafatis noted: “When they put the eMOD platform in the hands of their workers and field supervisors, there was a profound shift to proactive vs. reactive behaviors and measurements.”
Four Behavioral Changes That Reduced EMR by 24.5%
The mechanics of the study aren’t complicated, but they’re worth understanding. The EMR didn’t drop because the contractor changed its paperwork. It dropped because of what changed on the ground before mobilization.
- Pre-task planning became real-time and verifiable. Superintendents confirmed that every trade partner submitted and received JHA approval before crews mobilized — not after-the-fact, not in a paper binder. OSHA’s job hazard analysis guidance outlines exactly why pre-execution hazard identification is the foundation of any effective safety program. The verification gap closed.
- Worker safety profiles followed individuals across projects. Certifications, training records, and orientations travel with the worker. Credential gaps got flagged before the work started, not discovered during an audit.
- Hazard reporting shifted from reactive to proactive. Digital pre-task planning gave supervisors visibility into identified hazards before incidents occurred. Near-miss data became actionable.
- Administrative burden dropped for safety staff. Saving 884–1,300 hours per year means your safety officer spends less time chasing paperwork and more time on site, where the actual risk lives.
When Can Contractors Expect to See EMR Improvement?
This is the question every Safety Director asks, and the honest answer requires understanding how the EMR calculation works.
TRIR and DART improvements can show up within the first year of deployment — the Gallagher study documented measurable incident rate reductions in its first annual period, with workers’ comp premiums following at 46.3% reduction across three years.
EMR moves more slowly because it’s based on a trailing three-year claims period — that’s how NCCI calculates the modifier for most contractors. Industry experience suggests initial modifier movement typically appears in year two, with the full effect in year three and beyond. That’s not a reason to wait — it’s the opposite. Every month you’re not capturing incident data in a verifiable digital format is a month working against your next mod recalculation.
That math applies to a $12 million specialty sub just as much as it does to an ENR Top 400 GC.
How Digital Safety Management Enables Behavioral Change
The connection between digital pre-task planning and EMR reduction isn’t intuitive until you look at where claims actually originate. Most recordable incidents follow patterns — specific trades, specific task types, specific combinations of hazard exposure and inadequate pre-planning.
Paper-based pre-task plans don’t surface those patterns. They get filed, not analyzed. When superintendents can’t verify in real time whether a trade partner’s JHA was submitted and approved, they’re managing compliance on assumption. That’s the verification gap that drives liability exposure.
eMOD — built by field superintendents at Dome Construction who faced this problem directly — puts hazard identification in the hands of field crews with real-time supervisor visibility. The eMOD construction safety platform integrates with Procore and Autodesk, layering onto systems most mid-to-large contractors already use rather than requiring a parallel workflow.
The behavioral shift the Gallagher study documented is what happens when the barrier to pre-task compliance drops to near zero for field crews and verification time for management goes from delayed to immediate.
Start Measuring What Will Move Your Modifier
If reducing your experience modification rate is a priority — whether for insurance costs, prequalification requirements, or CFO pressure — the most useful first step isn’t another safety training. It’s closing the gap between what your safety program requires on paper and what you can verify actually happened in the field.
