Consolidating available information and drawing together international best practice is the aim of a new site investigation guide aimed at the tunnelling industry.
The Strategy for site investigation of tunnelling projects guide has been produced by the research working group of the International Tunnelling Association (ITA).
The need for the guide was identified by an executive council meeting of the ITA in 2001.
“This document presents the strategy for site investigations based on international best practice, with the aim of maximising the benefit in terms of acquiring knowledge at the right project phase, while avoiding common misleading approaches in terms of investigation effort and responsibility,” said working group leaders Chungsik Yoo and Elena Chiriotti. “It is hoped that this document will be a useful guide for future tunnelling projects.”
The guide set out the reasons for undertaking a site investigation, the components for different phases of the investigation and also covers documentation and contractual relevance.
