Accident Investigation and Reconstruction

Incident or accident happens in many ocassions such as workplaces, transportation, amusement, etc. often resulting in huge econormic loss and even human life loss, thus initiating litigation process or even legal proceeding. Accident investigation and reconstruction is a systematic process of collection and analysis of information, data and evidences relating to an incident or accident that led to the loss of property, time or health of individuals, or even lives. Accident investigation and analysis is the scientific and academic examination of the facts and informtions that occurred during an incident or accident. Accident investigation services are demanded by not only Singapore but also other countries's industrial and governments.

In litigations, forensic accident investigation reconstruction is necessary to reconstruct what happened during the accident and prepare investigation report for litigation, the accident investigator will be called on as accident investigation expert witness to testify in Court of Singapore or other countries. For more details about expert witness, click Expert witness in litigation and insurance claims.

What is effective accident investigation

After conducting failure analysis or accident investigation, the conclusion could be wrong, inconclusive or inrelevant, lack of logical or evidence, such kind of conclusion would be misleading, not only the analysis and investigation money as well as precise time are wasted, but also the failures or accidents could not be solved and prevented, it would further damage reputation and even litigation loss.

The effective failure analysis or accident investigation must be comprehensive, logical, adapt scientifically proven methods, and get right conclusion with solid evidence.

How to validate effective failure analysis and/or accident investigation

Effectiveness of failure analysis and accident investigation can be evaluated from following aspects:
