Building around existing tunnels seminar
April 27, 2023 @ 8:30 am - 5:00 pm AEST
Join the Australian Tunnelling Society (ATS) and Australian Geomechanics Society (AGS) for a one-day seminar on the impacts that building construction has on tunnels.
There is an increasing demand for the assessment of the potential impact of new building construction, including new tunnels, on existing tunnels and other underground infrastructure.
There are limited resources both on the approvals side and for developers to carry out these assessments and particularly in a timely manner.
The purpose of this seminar is for presentations, papers and a panel discussion to provide useful information for the broad range of participants involved. Particularly referring standards and guidelines including applicability of structural and geotechnical assessment criteria.
The tunnels involved could be road, rail, sewer or water supply. Topics could also include-analysis case studies, monitoring methods and data, dilapidation surveys, the approval process, predictions of impacts verses actual impacts and any economic, property or legal issues.
Morning tea, lunch and afternoon tea will be provided.
