Accident Investigations and Reconstruction

From head-on collisions and multi-vehicle accidents to rollovers and heavy or commercial trucking accidents, the accident reconstructionist team employs forensic and physics-based modeling to illustrate a vehicle position at any point in an accident sequence. Investigation include site and vehicle inspections, as well as crash data retrieval (CDR), or "black box" download and analysis. The investgations also include heavy equipment such as farm and construction equipment as well as industrial accidents. Reconstructions are conducted using mathematical analysis of vehicle motion, on-site surveys, and analysis of photographic evidence. Utilizing the expertise of our animation specialist, the accident reconstructionist not only provides an accurate portrayal of the accident based on the facts, but also conveys complex vehicle dynamics in a clear and understandable manner.
