Investigative Recontructions

Highlighted terminology is explained at the bottom of the page.

Forensic collision investigation is the scientific process of identifying, recording and securing evidence, followed by its evaluation, interpretation and analysis with all other collated evidence to formulate objective conclusions about the contributory and causative factors of a collision.

We provide an investigative mindset and capability to identify, record, secure and analyse evidence relating to a collison. Some of our methods involve data processing and calculations, computer simulations, sequencing of events, collision site analysis, vehicle examinations, extraction of vehicle-borne data and other investigative reconstruction methodologies.

In large and catastrophic loss collisions, often there is a lack of investigative opportunities taken during criminal investigations. This leads to a failure to identify, secure and analyse available sources of valuable information. We strive to mitigate these initial loses and recover valuable evidence.

As an independent company, we offer our clients a tailored and broad range of investigative opportunities to secure evidence that may have been overlooked.

Where required, our investigative reconstructions thoroughly explore the collision sequence to acquire robust and objective evidence to determine the road user actions during the pre-collision phase.

Although we only investigate and report on the matters of instruction, our investigations typically focus on the following four areas:

  1. Pre-Collision Road User Movements - The movements of all road users pre-collision.
  2. Collision Dynamics - The forces and motions occurring during a collision due to the interaction and engagement of collision-involved vehicles, objects or persons.
  3. Injury Mechanism - The analysis and determination of the mechanical behaviour leading to road user injuries.
  4. Road User Actions - The ongoing activities of a road user during the pre-collision phase.

In addition to the listed services, we perform vehicle headlight beam profiling, conspicuity analysis, deceleration rate acquisition, speedometer accuracy testing, image and video enhancement to name only a few.

We provide comprehensive, and research-backed objective analysis on all matters of instruction within a case. CollisionExperts has a digital library of over 13,000 peer-reviewed research papers.

Most importantly, our summary of conclusions offers objective evidence of fact, and opinion evidence in a concise and logical format.

 

CPR-Complaint Investigative reconstruction Reports

We produce comprehensive and objective CPR-compliant investigative reconstruction reports for our clients. Although we will only address our clients' matters of instruction, a typical report consists of:

Large and Catastrophic Loss CPR-compliant Investigative Reconstruction Reports

  1. The matters of instruction.
  2. The supplied evidence for consideration.
  3. The known circumstances of the incident.
  4. An objective analysis of the integrity of the supplied evidence.
  5. Investigative activities undertaken.
  6. An objective analysis and expert opinion of the background movements of the involved road users.
  7. An objective analysis and expert opinion of the collision dynamics.
  8. An objective analysis and expert opinion of the injury mechanism. The injury mechanism is also referred to as causation/unusual occupant movements/occupant accelerations.
  9. An objective analysis and expert opinion of the road user actions. (Conspicuity, perception response times, evasive manoeuvres etc)
  10. A summary of conclusions.

Low Speed Claim Validation CPR-compliant Investigative Reconstruction Reports

  1. The matters of instruction.
  2. The supplied evidence for consideration.
  3. The known circumstances of the incident.
  4. An objective analysis of the integrity of the supplied evidence.
  5. Investigative activities undertaken.
  6. An objective analysis and expert opinion of the consistency of vehicle contact damage.
  7. An objective analysis and expert opinion of the collision dynamics.
  8. An objective analysis and expert opinion of the injury mechanism from computer simulations and crash test reports. The injury mechanism is also referred to as causation/unusual occupant movements/occupant accelerations.
  9. A summary of conclusions.

Should our clients not require an investigative service, we offer a desktop analysis service.

 

Fees & Lead Times

Our service level agreements for fees and lead times for our investigative reconstuctions vary due to the complexity of each case and any investigative services required.

We strongly advise all our instructing clients to consider our all-inclusive investigative reconstruction package.

Please contact us to discuss your requirements.

 

Terminology

Collision Dynamics – The forces and motions occurring during a collision due to the interaction and engagement of collision-involved vehicles, objects or persons.

Collision Sequence – The chronological sequence of events involving the collision-involved vehicles, objects or persons.

Collision Scenario – The circumstances of a collision.

Conspicuity – The extent to which an object is discernible from its surroundings.

Evasive Manoeuvres – Actions taken by a road user to avoid a collision or minimise its severity.

Evidence of Fact – Evidence of verifiable, proven, robust and defensible information.

Injury Mechanism – The mechanical behaviour leading to an injury.

Matters of Instruction - The specific elements of a collision a client seeks consultancy for.

Opinion Evidence – Evidence of what a witness thinks, believes or infers.

Pre-Collision Phase – The actions and movements of the collision-involved vehicles, objects or persons prior to the impact phase of the collision.

Road User Actions – The ongoing activities of a road user during the pre-collision phase.
