Laser scans of the environment and vehicles were utilized to demonstrate how workers could have come in direct contact with a moving trailer. The laser scan of the environment included important information such as the curvature of the roadway, and the curb-to-curb width of the street. Laser scans of construction vehicles allowed DJS to properly place the vehicles on the roadway. With the remaining space, DJS prepared a to-scale pickup and trailer and had it move, according to the laws of physics, and witness testimony. To-scale workers were also placed according to witness testimony. Once all contributing factors to the accident were in place, DJS was able to illustrate, with a reasonable degree of engineering certainty, how the off-tracking movement of the trailer could have contacted the workers, standing nearby.
