Construction Accident Third-Party Claims
Workers' compensation is generally your only claim against your own employer, but on a construction site many other parties can be responsible. A third-party claim against a general contractor, another subcontractor, a property owner or an equipment manufacturer can recover pain and suffering and full lost earnings that workers' compensation does not.
Why Third-Party Claims Matter
Direct Answer: Because workers' compensation benefits are capped and do not compensate pain and suffering, a successful third-party claim can result in a far larger recovery than compensation alone.
Construction sites involve many companies working side by side. When someone other than your employer, such as another trade's negligence, an owner's unsafe premises, a defective machine or a design failure, contributed to your injury, that party can be sued in the ordinary way.
Who Can Be Sued
Depending on the facts, potential defendants include:
- The general contractor, if it controlled site safety
- Other subcontractors whose work created the hazard
- The property owner, for unsafe premises
- Manufacturers of defective tools, scaffolds, lifts or safety equipment
- Architects or engineers whose design created a danger
Workers' Compensation Liens
The workers' compensation insurer that paid your medical costs and wage benefits may have a right to be repaid from any third-party recovery, called a lien or subrogation claim. Negotiating that lien is a significant part of a settlement, so ask how it will affect what you keep.
