He will explore the utilisation of underground space and the development of ever more sophisticated construction techniques. Drawing on his considerable experience of working in the congested subterranean environment, Colin will present a summary of some of the challenges encountered when tunnelling beneath urban areas and some of the novel techniques he has employed to overcome them. Looking to the future, Colin will consider what challenges will be faced in the upcoming major tunnelling projects currently proposed for London and how the UK tunnelling industry can overcome them and maintain their position in a challenging international market.
