Seeking sustainability
30 August, 2022
With the global industry gathering in Copenhagen for the first in-person World Tunnel Congress for a few years, much more focus is on sustainability in the creation and long-term use of underground space.

Taking a grip
03 August, 2022
We are always looking to the future while trying to learn useful tips from the past, whether from our own history or the experiences of those kind enough to share lessons.

Being realistic
24 June, 2022
Using London’s newly-opened Elizabeth Line (Crossrail) is a wonderful experience. How marvellous when everything is fresh and operates seamlessly. Congratulations to all teams and crews involved.

See you in Philly

This issue of Tunnels & Tunneling North America (TTNA) will be circulated at the North American Tunneling show (NAT) and it’s gratifying to see that after a Covid-enforced break, NAT is back with us once more. It’s going to be a great show and we look forward to seeing you there.

A couple of milestones
23 May, 2022
We mark two completions this month, one momentous, the other – well, perhaps not so.

A Perfect Storm
22 April, 2022
Challenges come thick and fast. Energy price volatility, the war in Ukraine, supply chain disruptions, a global shipping crisis, the talent shortage, 30-year-high inflation, ‘great resignations’, and lingering Covid-19 (with new lockdowns in China) are combining to further impact our lives. To have so much disruption on so many fronts, simultaneously, is highly unusual and does not bode well. It could all be leading to a massive crisis.

Melons, peaches, almonds, pistachios, garlic and wine are just part of California’s bounteous agriculture that amounts to a US$50bn/year industry. If you include dairy, the Golden State supplies around one quarter of the food consumed in the US. But it will not for much longer if the drought continues.

Vitruvian man

This month, we feature the obituary of John Bartlett, inventor of the slurry tunnelling machine who died last year at the age of 94.

Time to get snapping
21 February, 2022
Over the past 50-odd years, technology has advanced at an astonishing rate. American theoretical physicist Michio Kaku’s famous assertion that today’s smart phone has more computing power than NASA had at the time of the 1969 Apollo 11 moon shot shows just how far we have come.

Taking the softer approach
28 January, 2022
As a non-engineer, my knowledge of tunnelling would have been undeniably poorer without my well-thumbed copy of ‘Introduction to Tunnel Construction’ by Chapman, Metje and Stärk. Thus invaluable ‘bible’ of a book, with its hugely ambitious scope, has been my trusted reference over the years, guiding me ever so gently through the difficult ground of tunnelling.
