COMMENT FROM THE EDITOR’S DESK - 26 Nov 2020

Conventional tunnelling is a term that has found common use in the industry. What it means exactly is more about what it is not. Anything other than TBM excavation is the widely accepted meaning, but that covers so many different excavation methods, and one could argue that TBM excavation of all types and sizes, is now also conventional.
