COUNTING TIME


We reflect upon seasons and change. Endings and beginnings. One beginning recalled in this


issue is the start of shaft sinking on Brunel’s Thames Tunnel, the 200th anniversary of which is this year. Creation of the transport tunnel in London led the way to the recognisable basics of modern soft ground tunnelling technology, and its many challenges. The subsequent evolution of


shield technology helped to develop transport tunnel networks in the different soft geologies of many cities across the world. Such underground corridors are vital to modern cities and their economies - even more beneficial when extended, costly when unavailable. Returning from summer to work,


commuters found much the London underground tube network’s trains taken out of service by industrial strikes for most a whole week. The costs in lost time and money, and in the impact to the economy, were enormous. Underground space is clearly, and


strategically, of vast importance to modern society and the economies of capital cities.


Society’s needs in the types of uses


for underground space continues to expand, such as to store spent nuclear fuel and radioactive waste for millennia. We look at the new tunnelling beginning in Sweden. In another feature, and concerning another type of energy, hydropower, we learn how TBMs and tunnellers have been opening a new chapter in capability to bore long headrace tunnels under significant overburden in mountains. In designing and building tunnels in


future, tunnellers will become more familiar with the pros and cons of AI, and always the need for excellence in health and safety. We look at both of these areas, the latter in a preview of the two-day BTS H&S course, in November. But, in the end, building


underground is all about people and bringing them together to do so, such as one of the tunnelling greats, Peter Bermingham, was praised doing so on many projects. Sadly, he passed away recently and we carry his obituary.
