SERVICES

  • Investigate and reconstruct vehicle, pedestrian, and bicycle collisions and incidents and provide analysis and expert testimony in civil and criminal cases. Reports and/or testimony are based on police reports, scene evidence, injury reports, vehicle examination and repair documents, witness interviews and depositions, photographs, and other documents and sources.

  • Develop vehicle collision speeds for both low speed and high speed accidents, based on momentum, operational and performance characteristics, and/or energy/crush methods utilizing trajectories and damage.

  • Calculate impact acceleration and change in velocity (delta-V). Correlate injuries with direction of forces and occupant positions in or about the vehicle.

  • Download data from vehicle event data recorders for incorporation in accident reconstruction analysis. (Such devices are variously known as EDRs, SDMs, RCMs, ACMs, and other acronyms, and are often referred to as “crash data recorders” or “black boxes.” Useful data is currently available on some General Motors, Ford, Chrysler and other brands produced since 1994 models.)

  • Assess police reports, witness statements, and depositions for inconsistencies, missing or incorrect information, or insupportable claims.

  • Ascertain whether damage and/or loss to vehicles is consistent with the statements of witnesses or interested parties.

  • Investigate contributing collision factors including weather, sun position, sight lines, driver distractions, and mechanical problems.

  • Investigate claims of defective function, and evaluate failure factors such as inadequate maintenance, poor engineering design, material fatigue, overstressing or abuse of equipment, improper modifications or replacement parts, and faulty workmanship.

  • Disassemble suspect vehicle components or systems and analyze the cause of failures. Document findings via photography, videography, and written description.

  • Research the records of government agencies, non-profit agencies, or manufacturers for part failure histories, vehicle recalls, and crash test results.

  • Analyze loads, stresses, and deflections under load for component parts or assemblies. Evaluate materials selection, engineering design, testing programs, manufacturing methods, and construction procedures.

  • Lamp examination to determine whether on or off at time of collision.

  • Research histories of roadways and intersections for previous accidents or hazardous conditions.

  • Prepare scale diagrams of accident scenes with relevant features noted.

  • Display accident sequences graphically to show the relative positions of involved parties at various time intervals leading up to and following the accident.

  • Construct photo records of vehicle inspections, accident scenes, or failed components and assemblies.

  • Produce video presentations to augment testimony, depict what was (and was not) visible to a given party, and to portray investigative procedures.
