The ITA COSUF TSO Webinar on Refurbishments of Road Tunnels (18 November 2021) organised by Activity Group 4 (Tunnels Safety Officers) supported by the Dutch Knowledge Centre for Underground Construction and Inderground Space (COB) was visited by 72 attendees mainly from Europe and few from India and New Sealand. This webinar was ment as a teaser for the bi annual TSO Forum in 2022, where the main topic will be tunnel refurbishment. This TSO6 will be organised on June 9 and 10th 2022 in Bruxelles. After a brief introduction by ITA COSUF Chairman Max Wietek the main programme started with a presentation by Silvester Heijdemann (Rijkswaterstaat) and Harry de Haan (Rijkswaterstaat) of the renovation of the Heinenoordtunnel in the Netherlands. Besides renewals of equipment, a new safety concept with a central escape gallery is created and during construction one tube is in operation most of the time which is a challenge.  A second presentation was provided by Program Director Richard Bormans of Arcadis who is assigned by the Flamish Road Authority to carry out the preparations for the total and integral renovation of the Vierarmentunnel in the Brussels ring road and of the Beverentunnel in the Antwerp ring road. In this assignment BIM models, tunnel safety documentation and renovation files are supplied for both the TERN and non-TERN road tunnels. 

Both presentations showed that to prepare a road tunnel renovation one should not only focus on a safe final situation, but also on the construction phase where part of the tunnel is in operation.

On the 20-21 October 2021, an international meeting was held for the second time on new energy carriers for road transport, such as battery electric vehicles, vehicles propulsed by natural gas and hydrogen, and the negative consequences these new energy carriers can have for underground infrastructure. Due to the covid-19 pandemic, the conference was completely digital. Like the first congress in February 2019, it was organized by PIARC, ITA-COSUF and KPT. The various presentations show that knowledge about the risks of the new energy carriers has increased significantly in the past two years and that various solutions have been identified to manage these risks
