Company Profile

Sayre & Associates Forensic Engineering is a multidisciplinary team of engineers and retired Kentucky State Police reconstructionists with over 100 years of combined reconstruction training and experience.  Our SAFE team was formed to provide statewide accident reconstruction services to our clients and the capability to respond immediately to serious crashes.  With offices in Lexington, Murray, Hindman, and Frankfort we can get a reconstructionist on scene rapidly to thoroughly document critical physical evidence, begin vehicle inspections and meet with adjusters, police officers and safety personnel.

Our services include extensive digital photography, total station mapping of scenes and vehicles, forensic trace evidence collection, skid testing, detailed vehicle crush analysis, occupant kinematics and injury causation analysis, downloading computer data from passenger and commercial vehicles and we can provide aerial photography on special cases.  Our philosophy is do the hard work now, thoroughly and professionally, so all of the tough questions to come later can be answered in the same manner.  We believe our multidisciplinary training and experience is invaluable, but we also know that well documented physical evidence will the basis of our ultimate opinions.

Our rapid response capabilities can help prevent the loss or destruction of critical physical evidence.  As everyone knows, tire marks, scrapes, gouges, spillage, debris, pieces and parts as well as vehicles can disappear suddenly and important evidence can be lost or spoiled.  Furthermore, the sooner such evidence is documented the sooner some critical questions can be answered and proper reconstruction protocols can be initiated.
Each investigation is different but the evidence found determines what needs to be done
for accident causation as well as injury causation analyses. 

We also have an indoor vehicle inspection and storage facility in downtown Lexington.
With a vehicle lift, extra lighting, tools and a comfortable workspace, forensic inspections will be more efficient and less expensive and can be easily arranged to accommodate your schedule including nights and weekends.  Contact us if you need to store a vehicle or component or would like to use our facilities for an inspection by your experts or others.
