ITA launches survey into precast concrete segmental lining damage

ITA-AITES Working Group 2 (WG2) – Research is developing a publication on damages of precast concrete segmental linings, with the intent being to better understand damage that occurs during tunnel construction and operation.

As part of this study, a survey is being made to support the report being prepared by WG2 into segment damage, avoidance and repair. ITA WG2 would be very interested in receiving data from completed and ongoing projects from around the world. Any data on segment damage will be useful to the study, regardless of how it is categorized and recorded. The detailed information provided will be kept confidential and will only be reported at a level that cannot be attributed to individual projects or companies.

ITA-AITES is asking for the cooperation of Member Nations and national Tunnelling Associations to inform promptly national members, projects’ representatives, contractors, etc. potentially concerned about the existence of the questionnaire and the interest to collaborate for the collection of information.
