Synopsis

TBM technology is constantly being developed, with machines now capable of much more than they could just a few years ago. However, there are still instances where TBM’s have struggled or even failed to complete the planned tunnel construction. This talk will review some notable successes and also failures, and describe some of the key factors that have contributed to the project outcome.

The talk will also include a review of the latest developments in TBM technology, ranging from the traditional elements such as cutter performance, maintenance, ground conditioning etc., novel TBM developments, and also on digital developments such as automation, intelligent data management and application of machine learning, that can assist with the optimum operation of the TBM.

About the Speaker

Guy graduated with a degree in Exploration and Mining Geology from Cardiff University, UK, and with the lack of employment opportunities in Mining in the UK, started his career on a road tunnel project in the UK. After several years working both on site and in the design office, he came to Hong Kong in 1999 to work on Westrail Tai Lam Tunnel and Nam Wan tunnel at Tsing Yi. Although his first projects largely comprised drill and blast tunnels, he has since played a key role in the design and construction of a number of TBM tunnels in Hong Kong, Singapore, India and the Middle East. 

He has 30 years of experience in design and construction of tunnels and is currently an Executive Director with AECOM.

He is currently responsible for leading a tunnel team undertaking the feasibility study of a new metro line in Dubai, advising on tunnelling aspects for new metro tunnels and stations in Singapore, and providing supervision services for two TBM tunnelling projects in Hong Kong. He is a Fellow of the Institute of Materials, Minerals and Mining, and Registered Professional Engineer with HKIE.
