Lobbying can be a force for good
11 October, 2021
So, amid much anticipation, the US Senate has finally passed the US$1.2 trillion bipartisan infrastructure bill. Now, the package must clear the House, after which it will go to the president who will sign it into law.

Tunnel flood woes any ideas?
12 August, 2021
This month, in Zhengzhou, China, at least four people died when a road tunnel almost completely filled with water following a record 624mm of rain in 24 hours. During the same weather event in that city, a subway tunnel was deluged, with commuters up to their knees in water. In London, less dramatically but equally worrying, torrential rain and flash flooding put at least two stations out of action. And there are other instances elsewhere.

A new era, A new look
27 July, 2021
July 2021 brings a fresh new look to Tunnels and Tunnelling which has been designed to bring order, clarity and a more relaxed feel. But the changes are not just aesthetic. We have made structural changes to ensure T&TI keeps up with the times.

Notes from underground
07 June, 2021
Persuading lay people and decision makers of the potentially life-improving benefits of subsurface developments can be an uphill task. The popular imagination has been conditioned since childhood to think of the underground in terms of being dark, dirty, unwelcoming and potentially menacing, not a place to linger in for long.

First, there was Elon Musk who claimed to be able to increase the speed of TBM tunnelling by ten.

A tool of conservation
05 April, 2021
Some of you may raise an eyebrow or two at the article on p29 of this month’s issue of T&TI seeing it is an extract from an arts magazine. But I make no apologies for its inclusion in this distinguished tunnelling journal.

Here’s to another 50 years
23 March, 2021
In my current capacity as chairman of the Tunnels and Tunnelling Editorial Advisory Board (EAB), I was pleased to be asked by the Editor George Demetri to write this comment on the occasion of the 50th anniversary of the British Tunnelling Society (BTS).

Making progress
15 March, 2021
There are now around 9.5m fewer jobs in the US than before the pandemic. President Biden is planning to rebuild American infrastructure at a time of profound national crisis when he could have been forgiven for concentrating on a stimulus package which prioritised unemployment, coronavirus vaccines, childcare and other pressing social issues.

And the winner is…
29 January, 2021
It was a great honour and privilege to be asked by the ITA to represent T&T on the judging panel of the ITA Tunnelling and Underground Space Awards 2020. Like many events these days, they were held virtually with the online judging completed in November and the awards presented on December 4.

Can Joe lift infrastructure?
28 January, 2021
‘Crumbling infrastructure’ is a term that is heard frequently in the US, particularly to describe transportation and public utilities. Perhaps ‘infrastructure crisis’ is a better term. According to the American Society of Civil Engineers (ASCE), the US will need to spend US$4.5tr on infrastructure by 2025 to avert ‘serious economic consequences’.
