Consulting, expert opinion, research

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.

HBI has the high level of competence and broad experience required to serve as an independent inspection entity. The service that includes assessment of the safety and scrutiny of the safety documentation is targeted to assist in particular the administrative authority. The EU-Directive 2004/54/EC dated 29 April 2004 on minimum safety requirements for tunnels in the trans-European road network prescribes that a safety documentation has to exist. Moreover, the organization shall consist of various entities with clearly defined roles and responsibilities: administrative authority, tunnel manager, inspections entity and safety officer.
