Accident reconstruction is a discipline governed by the laws of physics and related sciences.  Many of the calculations required to perform a reconstruction are based upon simple principals.  However, the application of these principals is often complicated by the need to carry-out many combinations and iterations of the base calculations.  Civil & Forensic uses state of the art software applications to aid our Engineers in performing the necessary calculations in a timely manner.  Software used includes CivilCad, Rec-Tec, EDSMAC, EDSVS and EDVTS, as well as in-house developed spreadsheets and programs.  All software is designed to run in Intel platform computer equipment running under Microsoft DOS or Microsoft Windows 95/NT.
 
CivilCad - a Civil Engineering and Survey suite of programs that enables the modeling of 3D Terrain models (land forms) obtained from accurate survey of an accident site.  3D Terrain models can also be obtained and imported into CivilCad from road construction authorities (such as Local Councils and the RTA) enabling the investigation of accident site that may have been altered by road works since the time of the accident.  CivilCad includes tools for road, survey and drainage drainage design enabling Civil & Forensic to quickly and accurately analyze an accident site.  In addition, 3D Terrain models from CivilCad can be used for the preparation of accurate site plans and as the basis for the 3D Animation of an accident.
 
Rec-Tec - a suite of computer programs that incorporates many of the equations of accident reconstruction.  These include Time and Distance, Momentum, Yaw, Swerve, Rollover, Launch, Fall, Kinetic Energy, Weight Shift, Photogrammetry, Pedestrian Impacts and Vehicle Crush calculations.  [ more info on Rec-Tec]
 
Engineering Dynamics Corporation (EDC) - Computer simulation programs from EDC enable two vehicle trajectory and collision analysis (EDSMAC), single vehicle trajectory analysis (EDSVS) and vehicle-trailor trajectory analysis (EDVTS).  These analyses take into account road and pavement conditions, tyre performance, vehicle properties, as well as acceleration, braking, deceleration and steering (driver) inputs.  All EDC applications have been validated using test data.  Civil & Forensic are currently beta testing HVE-2D, the next generation of simulation programs from EDC.  [more info on EDC programs]
