David was honoured to be invited as the Keynote Presenter at The 8th International Symposium on Advances in Civil and Environmental Engineering Practices for Sustainable Development at Ruhuna University. The Symposium was held via video conference but had many attendees on line.
David's presentation "Constraints on the application of modern tunnelling techniques to projects in Sri Lanka and SE Asia" was well received with many positive and favourable comments about the speech and the style in which it was delivered.
The whole event was well organised and a great success in these difficult times.
