Accidents and injuries on the job site are common and may initially appear to be only a Worker's Compensation matter; however, this is not always the case. Negligence can result from malfunctioning, improperly designed, or poorly maintained pieces of equipment or materials, and from faulty or improperly constructed buildings, whether completed or under construction.

An investigation into such accidents provides the background information necessary for determining whether or not there is a third party responsible for the accident. In such cases the owner, designer, builder, general/sub-contractor, or maintenance contractor are identified.
