Subcontractor Fall Claims and Your Mod: What GCs Must Document

A Massachusetts appellate court ruled in 2025 that a general contractor was not directly liable for a subcontractor's employee who fell from a roof (Massachusetts Appeals Court, 2025). The GC had delegated roofing work to a subcontractor. The sub's employee sued the GC. The court said no: the GC retained no control over the roofing means and methods, so the tort claim failed.

That is the legal story. The workers' comp story is different, and it lasts longer.

If the injured worker's claim runs through your policy rather than the sub's, the experience modification impact hits your experience modification rate for three policy years. Winning the tort case does not touch the mod. The mod responds to claim dollars on the worksheet, not to fault.

The fall-protection numbers behind the risk

OSHA issued 11,842 fall-protection citations in fiscal year 2024, the most frequently cited standard for the 14th consecutive year (OSHA, October 2024). The construction industry accounted for 1,016 fatal falls in 2023, the highest count since 2016 (BLS Census of Fatal Occupational Injuries, 2024). Roofing work drives a disproportionate share.

For Southeast contractors, the exposure is constant. A single severe fall can produce a claim valued at $250,000 to $500,000 or more once medical, indemnity, and reserve padding are included. On a contractor with $3 million in expected losses, a $400,000 claim can move the mod from 0.95 to 1.15 or higher, depending on where it lands relative to the split point. That 20-point swing follows you into every bid room for three years.

Legal fault and EMR cost are separate problems

The Massachusetts decision turns on control. The court found the GC did not retain control over the subcontractor's roofing methods, so the GC was not liable for the employee's injury. That is a tort standard. It answers who pays for the worker's damages outside the workers' comp system.

The EMR answers a different question. It asks whether the claims on your policy are worse than expected for your class codes and payroll. If the sub was uninsured or underinsured and the claim landed on your policy via an uninsured subcontractor endorsement, your mod absorbs the loss. If the sub had its own coverage but you were named on the suit and the claim touched your policy through additional-insured provisions, the outcome depends on how the carrier reported the loss to NCCI.

The point is simple. A court can clear you of negligence. Your mod still reflects the claim dollars.

What drives the mod damage

The reserve the carrier sets early in the claim life is what hits the worksheet. NCCI experience rating uses the reported losses, including reserves, not the final settled amount. A $400,000 reserve on a severe fall stays in your experience period until the claim closes and the final settlement replaces the reserve.

That lag is the three-year problem. The claim enters your mod in the first year. It sits there for the second and third. If the reserve was set high and the claim later closes for less, you get a correction, but only on the next available worksheet. The money you overpaid in premium during the interim years is gone unless an audit recovers it.

For a contractor bidding public work in the Southeast, a mod above 1.00 can disqualify you or push you into a higher tier. Some project owners require a mod of 1.00 or below. A single severe claim can cost you prequalification for the duration of the experience period.

What an audit would check

An audit checks whether the claim on your worksheet belongs there at all, whether the reserve matches the carrier's current claim file, and whether the classification codes assigned to the subcontractor's work are correct. It also checks whether the subcontractor's payroll was properly excluded or included based on the insurance status at the time of the injury. Most contractors we review have at least one claim on their worksheet where the reserve has drifted from the actual exposure, or where a sub's claim should not have been on the GC's policy in the first place.

Before the claim, the documentation that matters is the certificate of insurance with adequate limits, the subcontractor agreement that defines insurance obligations, and the OSHA 300 log that shows your safety program was active on the site. After the claim, it is the reserve letter from the carrier and the claim status report that shows whether the reserve is tracking toward the real cost.
