He authored or co-authored more than 30 international publications and participates in various technical and regulatory groups, including PIARC and the Channel Tunnel Safety Authority.

Alan Vardy

My home, Scotland, is better known for its whisky, haggis and kilt-wearing men than for its tunnels, of which there are very few. However, I am rather fond of all of these, the first two for pure enjoyment and the third for never-ending stimulation and challenge. My software (ThermoTun) has been widely used for simulating pressure disturbances in high-speed railway tunnels and my control software for road tunnel ventilation has stood the test of time in Japan. Also, in the 1990s and 2000s, I ran a series of international conferences on tunnel safety. In short, a ‘Jack-of-all-trades, and a master of none’, but a happy chappie nonetheless.

Günter Rattei

Günter Rattei has been dealing with tunnel safety issues since the 1990s and was able to set up and manage the tunnel management department at ASFINAG, whose task is to implement the specifications of the EU directive and national specifications.
