Construction Site Injuries & Third Party Claims in Washington State

It’s too easy to be injured on a construction site. Exposed rebar, moving vehicles, unmarked hazards, burns, electrical shocks, cave ins, falling material, trench collapses, chemical exposure, lack of safety meetings, crane injuries, falls, careless subs and other unsafe conditions all cause injuries. Construction site injuries can create both L&I claims and Third Party Claims.

Construction site L&I claims are for the most part like any other L&I claim. Information about how to handle an L&I claim is all over this website. L&I Benefit Information and L&I Claims – A Beginners Guide.

The unusual thing about construction site injuries is that they often create two claims.

Two Claims in One, L&I Claim and Third Party Claim.

A worker hurt on any job in Washington State has an L&I  workers compensation claim. A construction worker may also  have a third party claim. 

Construction L&I Claims?

L&I is no fault workers’ compensation coverage in Washington State. After a job injury the worker and their doctor file a Report of Accident with the Department of Labor and Industries. This begins the L&I claim for medical and money benefits. There is no requirement or need to prove that someone was at fault.

Third Party Claims in Washington State

L&I third party claims are negligence (fault) based. Fault is important.  The injured worker must prove the negligence of the third party.

Construction Site Injuries and Accidents Often Involve Both L&I Claims and Third Party Claims.

You have a third party claim if you are injured while on the job, by someone who is not your employer or a co-employee.

A third party claim is a personal injury claim together with an L&I claim, arising out of the same set of facts. When you have both an L&I claim and a personal injury claim, the personal injury claim is called a third party claim.

Third Party Claim Example #1

An employee of a subcontractor injured on the job by the general contractor or a different subcontractor has a third party claim. That employee has an L&I claim for the on the job injury and a third party personal injury claim because someone who is not his employer or co-employee injured him.

Third Party Claim Example #2

A truck driver on the job is injured on the highway in an accident involving  another vehicle. This truck driver may have two claims. He has a no fault L&I claim for having been injured on the job. He also may have a third party fault based personal injury claim against that other driver.

Can I Have Both an L&I and a Third Party Claim? Can I Sue the Third Party?

Yes, you can have an L&I claim and also a third party claim. You can have them both at the same time.  The L&I claim has a 1 year Statute of Limitations.  The third party claim has a 3 year Statute of Limitations.

Why Would I Want to Sue a Third Party if I Have an L&I Claim?

You pursue a third party because third party claims pay monies not available from L&I. You can recover for all your lost wages, injuries, pain and suffering, and future loss of earning capacity.

L&I claims pay less than what you have lost. Time loss money is limited. Permanent Partial Disability settlements are small. L&I does not pay enough.

Can I Recover Money Under Both Claims – L&I and Third Party?

Yes, you can recover under both systems subject to the subrogation rights of L&I. How you proceed with a third party claim while being wary of L&I’s subrogation is important. Get details at Third Party Claims.

Statute of Limitations

There are very important time deadlines for both third party claims and L&I claims. Don’t miss your deadline.

What About Fault in L&I Third Party Claims? Learn the Rules.

A third party claim requires fault (proof of negligence) to be successful.

  • The general contractor has a common law duty to maintain a safe workplace, and a statutory duty to comply with WISHA. The general also has vicarious liability for the negligence of parties to whom it delegates, and for the negligence of parties over whom it exercises control.
  • Sub contractors are responsible to ensure a safe work place regarding their scope of work and the zone of danger under their control. A breach of duty is evidence of negligence.
  • The material suppliers are responsible for the movement and storage of the materials they bring on to the work site.
  • The manufacturer of products is responsible for the foreseeable consequences of safe use of their product. These products can be defective or toxic and dangerous. They can be the subject of a successful third party lawsuit.
  • Landowners should keep their property free of dangerous conditions. If their negligence injures you, consider a third party lawsuit.

To be successful with a third party construction site case you will need to prove fault. To prove fault you need evidence. Evidence can disappear quickly. It is important to take pictures, find and talk to witness, gather investigative reports, and encourage WISHA inspectors to visit the site. Get legal help if you need it

Insurance Companies and Lawyers

Construction site accidents are vigorously defended by experienced insurance adjusters and their stable of aggressive defense lawyers. To get the insurance company to take you seriously you will want to have your own lawyer.

Can I Sue My Employer?

You can sue a third party, but you cannot sue your employer or coworker for a job injury.   The L&I system replaces your ability to sue your employer for his negligence. It doesn’t matter that it’s your employer’s fault. An exception to this rule is intentional injures. If the employers’ conduct was so over the top that he intended the injury then the employer can also be sued. More information at  Can I Sue My Employer?

Another semi-exception to this rule exists for Temporary Workers. For more information see Temporary Agency Employee and Third Party Rights.

What is a Third Party Election Form?

The third party election form starts the third party claim. This form is important. This is how you tell L&I what to do and where to go. Understand what you are doing before you complete this form. Don’t give up your right to a third party claim. Get details and a form here, Third Party Election Form.
