Our engineers have been assisting attorneys and insurance representatives in investigating accidents since 1990. We have a highly qualified staff of engineers with advanced degrees from top-tier universities who have provided testimony on behalf of both plaintiffs and defendants at trial
An SUV lost control and traveled over a portion of highway guardrail before rolling down an embankment, destroying the roll cage's integrity. The defense theorized the driver was killed by intruding guardrail posts as the SUV rolled along the guardrail, and that a stronger roll cage design would not have protected him. We reconstructed the accident using computer modeling, which disproved the defense's theory and showed that the driver would have survived if the roll cage had been designed stronger.
Water Wagon Rollover at Landfill
The driver of an articulated water-tanker tractor was injured when the tank trailer rolled onto its side, causing the tractor to roll with it, crushing his arm. The plaintiff claimed that the articulating hitch that was used by the manufacturer was inappropriate in that it did not allow the water tank to roll over independently of the tractor. Using a 3D computer simulation, we demonstrated that the proposed design change could not have prevented the accident.
