Accident Reconstruction
Accident reconstruction is the process of using physical and factual evidence, in conjunction with mathematics and physics, to determine how an accident occurred. When conducting any investigation or reconstruction, Packer Engineering uses the "scientific method." The scientific method is a process of inquiry which relies on four elements: observation, hypothesis, theory, and experiment. The underlying objective is always the same even though interaction between these four elements may differ from one situation to another.
While most accident reconstruction involves automobile accidents, many times our engineers perform accident reconstructions involving structural collapses, personal injuries, slips and falls, explosions, biomechanics, and human/machine interaction. During vehicular accident reconstruction, we can determine the impact speeds and directions of the vehicles involved, the time and distance relationships between the vehicles prior to the incident, and the impact severity (Delta V) relative to passengers or pedestrians. Our engineers use several techniques of data collection and analysis, including the methods of conservation of momentum, computer simulation, photogrammetry, and component or full scale crash testing.
When investigating insurance claims, Packer Engineering provides a wide range of services which enable insurers to validate claims, assess damages, and effectively manage losses. Contact Packer Engineering to find out how our engineers can meet your accident reconstruction needs.

Automotive Accident Reconstruction
Accident reconstruction is the process of using physical and factual evidence, in conjunction with mathematics and physics, to determine how an accident occurred. Vehicle, lift truck, and railroad engine manufacturers, rail carriers, transit system operators, and insurers work with Packer Engineering to investigate and reconstruct vehicular accidents. During vehicular accident reconstructions, Packer engineers determine the impact speeds and directions of the vehicles involved, the time and distance relationships between the vehicles prior to the incident, and the impact severity (Delta V) relative to passengers or pedestrians. Our engineers work with several techniques of data collection and analysis, including the methods of conservation of momentum, computer simulation, photogrammetry, and component or full scale crash testing. Packer Engineering also securely collects and stores for our clients the wreckage, artifacts, and evidence from accidents. Services include:

Engineering Mechanics
We utilize a variety of scientific techniques to carefully investigate and gather information concerning the Who, What, When, Where, and How of an accident. We then apply our engineering expertise to analyze the accident including the machine or equipment involved, the accident site and environmental factors, and the human interactions and inputs related to the accident. Depending on the type of equipment involved, the information available, and the needs of our client we can provide a wide range of services in this area including:
- Vehicle and Equipment Inspections and Investigations
- Accident Site Inspections, Surveys, and CAD Drawings
- Vehicle Dynamics and Impact Severity Determinations
- Crash Testing
- Visibility Studies
- Accident Reconstruction and Animations

Materials Engineering
Many times an accident involves broken materials. A small crack invisible to the naked eye can have catastrophic consequences. Our materials engineers possess the capabilities to determine whether a given failure was due to the application of extraordinary forces, improper design, selection of the wrong materials, presence of an environmental factor, or the result of a material flaw. Packer Engineering possesses the critical knowledge needed to analyze why and how a material failure contributes to an accident.
