Measurements, tests, commissioning and acceptance

We provide support for the commissioning and the initial operation phases of ventilation installations; we plan and support the execution of ventilation tests for certifying functionality. By means of our comprehensive measurement and testing equipment we execute fire and smoke tests as well as aerodynamic and climate measurements in tunnels.

Detailed design, functional tests and fire tests

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 exits.
