Tunnels that are object of the Consulting Services carried out by Sering are located along roads of national importance, length at least 500 m. The field survey made  possible to define all allocations, compared instead  of how the currents regulations impose: in many  cases these allocations have proved to be insufficient, as it was, for example, found the  complete lack of lighting systems (standard and  emergency). Often lacking from the point of view of ventilation and communication systems and almost  never equipped with evacuation systems outwards.

The main activities included  safety study, risk analysis and identification of maintenance works  and may be summarized as  follows:

  • Cataloguing of Tunnel System,
  • Vulnerability analysis and identification of anomalies and/or deficits, through systematic verification of the characteristics of each tunnel (“real tunnel”) with respect to regulatory requirements (“virtual tunnel”) identifying the differences (deficit or additional elements of security);
  • Quantitative Analysis of risk and the representation of the results in the diagram probability consequences;
  • Identification and preliminary evaluation of the possibilities of improvement especially for the tunnels with risk levels higher than the curve of acceptability or falling in the area called ALARP;
  • Verification of documentation and the results by a team of experts
