Wed, 03 Aug 2022 11:41:09 GMT Being realistic http://www.tunnelsonline.info/blog/being-realistic http://www.tunnelsonline.info/blog/being-realistic 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. Fri, 24 Jun 2022 13:48:23 GMT See you in Philly http://www.tunnelsonline.info/blog/see-you-in-philly http://www.tunnelsonline.info/blog/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. Wed, 22 Jun 2022 06:32:06 GMT A couple of milestones http://www.tunnelsonline.info/blog/a-couple-of-milestones http://www.tunnelsonline.info/blog/a-couple-of-milestones We mark two completions this month, one momentous, the other – well, perhaps not so. Mon, 23 May 2022 11:12:19 GMT A Perfect Storm http://www.tunnelsonline.info/blog/a-perfect-storm http://www.tunnelsonline.info/blog/a-perfect-storm 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. Fri, 22 Apr 2022 09:05:12 GMT Saving the land of milk and honey http://www.tunnelsonline.info/blog/saving-the-land-of-milk-and-honey http://www.tunnelsonline.info/blog/saving-the-land-of-milk-and-honey 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. Thu, 14 Apr 2022 06:16:35 GMT Vitruvian man http://www.tunnelsonline.info/blog/vitruvian-man http://www.tunnelsonline.info/blog/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. Thu, 17 Mar 2022 09:46:08 GMT Time to get snapping http://www.tunnelsonline.info/blog/time-to-get-snapping http://www.tunnelsonline.info/blog/time-to-get-snapping 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. Mon, 21 Feb 2022 12:41:10 GMT Taking the softer approach http://www.tunnelsonline.info/blog/taking-the-softer-approach http://www.tunnelsonline.info/blog/taking-the-softer-approach 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. Fri, 28 Jan 2022 06:27:00 GMT Bla Bla... And a brighter future http://www.tunnelsonline.info/blog/bla-bla-and-a-brighter-future http://www.tunnelsonline.info/blog/bla-bla-and-a-brighter-future 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.
