We provide professional consultancy services in all relevant aspects on tunnel ventilation, aerodynamic, climate, safety and risk analysis, tunnel equipment, and pollution dispersion. We prepare expert opinions in these areas on behalf of constructors and public authorities. We draw on our long-term experience of more than 1000 international projects and the continuous engagement in research and development.
New or adapted norms and guidelines lead to changing requirements for tunnel constructions. Changes of the usage requirements can lead to new performance requirements. With the check of the functional and safety requirements of existing tunnels by HBI, the safety level is determined and the need for action and the measures to be realized are demonstrated.
