Services
Accident Reconstruction
Our engineers investigate vehicle, motorcycle, and industrial accidents using physics-based modeling. We analyze evidence to determine causes and sequences, creating courtroom-ready reports and animations. Clients receive clear explanations of factors like speed, braking, and visibility.
CDR Data Retrieval
We extract critical data from vehicle event recorders using Bosch CDR tools. This includes pre-crash speed, brake application, and seatbelt usage. The data helps reconstruct accident dynamics and supports legal or insurance claims with objective evidence.
3D Scanning
FARO scanners capture precise measurements of accident scenes or equipment. The data creates interactive 3D models for courtroom presentations. This technology preserves evidence digitally and enables detailed spatial analysis for complex cases.
Expert Witness Testimony
Our ACTAR-certified specialists provide expert testimony in depositions and trials. We explain technical findings through demonstrative exhibits, ensuring juries and legal teams understand accident mechanics and failure analysis in plain language.
Premises Liability
We investigate slip-and-fall incidents using floor friction testing and security camera reviews. Our WACH-certified team assesses warning signage, lighting, and environmental factors to determine liability and compliance with safety standards.
