BTSYM Lecture: History and Future of Soft Ground Tunnelling

The birth of soft ground tunnelling started not far from the Institution of Civil Engineers building nearly 200 years ago. Tunnelling technologies and principles used today are founded on the early tunnelling pioneers particularly in the UK and notably London. The last 20 to 25 years have seen a rapid acceleration in urban tunnelling for metros and water related projects. The current demand has enabled the market to invest and improve this aspect of industry allowing us to excavate and support tunnels in soft ground conditions that would have been considered 'too difficult' 30 or so years ago. With the emphasis on the recent historical past Martin will narrate the significant influences that have shaped our soft ground tunnelling industry. The lecture was previously given at the annual ITA training session in Bergen in June 2017.

Harding Prize Competition

The three finalists of the Harding Prize competition will give an oral presentation of their papers and the audience will be invited to ask questions.


BTS AGM followed by BTS/BGA Lecture: Crossrail's Experience of Geotechnical Baseline Reports – A Client's Perspective

The presentation sets out to record Crossrail’s experience of GBRs from the client’s perspective. It covers why Crossrail adopted GBRs, where they were adopted and summarises how they were adopted. A semi quantitative assessment of the performance of the GBRs is then presented along with an analysis of the types of encounter that gave rise to successful compensation events. The presentation closes with a subjective view on whether the GBRs were a success and some thoughts on who is best placed to write them.

BTSYM June 2018 Meeting


Harding Memorial Lecture: Collaboration, Communication and Competence in the Tunnelling Industry

The lecture will look back over the speaker’s 50 years in the construction industry when he was principally engaged in tunnelling and consider whether we have achieved improvement in the key areas of Collaboration, Communication and Competence. How we might recognise improvement and the contribution made by these areas to the health of the tunnelling industry will be identified. Then how we might utilise what we have learnt to shape our industry going forward, the good omens and the not so good omens.
