Being realistic
Friday, June 24, 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
Wednesday, June 22, 2022 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
Monday, May 23, 2022 We mark two completions this month, one momentous, the other – well, perhaps not so.
A Perfect Storm
Friday, April 22, 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.
Saving the land of milk and honey
Thursday, April 14, 2022 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
Thursday, March 17, 2022 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
Monday, February 21, 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
Friday, January 28, 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.
Bla Bla... And a brighter future
Wednesday, December 29, 2021 So, here we are at the end of another year. I guess I could drone on, Greta Thunberg style, about how difficult these 12 months have been for us all bla bla bla; the pandemic bla bla bla; the amazing T&T redesign bla bla bla. But I won’t.
Old not obsolete
Tuesday, December 28, 2021 An interesting news story caught my attention this month concerning the fate of a 126-year-old freight tunnel in the US. Far from abandonment, disrepair or demolition, the Howard Street Tunnel (HST) in Baltimore is to get a new lease of life. And it’s a wonderful story.
