Why work with us?
We look at the contribution of human, vehicle and environmental factors, and give advice on individual issues to complex, multidisciplinary investigations. After an initial review of available documentation, our experts are able to provide preliminary advice focusing on the main issues, thereby providing you with early and cost-effective advice to better inform subsequent decisions on liability and assist in reducing overall client and court costs. A full reconstruction report will give you a clear understanding of the contributory factors of the accident.
