In this first 'Industrials Talks' discussion, we talk about the application and maintenance of tunnel boring machines or TBMs.  We go over a case study from recent a very recent project, 2020-2021 under COVID controls, discussing how to improve the productivity of this important machine.  We chat about how to get productivity from the machine itself, the logistics and processes that must take in place, and be in place, skills and knowledge required to ensure you improve and sustain change.   It's a fascinating discussion that bring together all the concepts required to achieve total transformations.
