13 September 2001
The World Trade Center was attacked on Tuesday 11 September in New York, shortly before 9am. Meanwhile, the working day was drawing to a close in London, where NCE was about to go to press with its 13 September issue featuring news on Labour’s first 100 days since re-election, and Coventry City Football Club’s new stadium plans. Of course, when the tragedy began to unfold NCE’s news team quickly gathered analysis from leading engineers and secured technical drawings from the towers’ designer, just in time for the issue to get to the printer.
20 September 2001
The following week, NCE brought you in-depth details, analysis and coverage of what had happened, what the immediate recovery concerns were, and what the long-term consequences of the event could be.
27 September 2001
Coverage continued the next week, as engineers got to work on making Ground Zero safe, rectifying infrastructure problems caused by the collapse, and asking probing questions about whether the towers were let down by their design.
4 October 2001
NCE continued covering the story as a New York task force looks into the attacks, and UK industry figures weigh in on the future of high rise buildings.
11 October 2001
On the one month anniversary of the tragedy, NCE looked at what engineers were doing practically, both as volunteers on site and in discussions with clients at home.
The number of engineers working round the clock at Ground Zero is drastically cut.
NCE looks at how designers can reassure clients that megatowers are still economically viable.
18 October 2001
As more weeks passed, industry figures in the UK began to question what would happen if the attacks were repeated here.
Emergency planners say UK local authorities cannot respond adequately to disasters like the 9/11 attacks.
Detailed forensic investigations at Ground Zero still have some way to go, an expert tells NCE.
25 October 2001
As the end of October approached, plans for Subway repairs and basement stabilisation in New York City became clearer, and the importance of evacuation routes in the disaster was discussed.
1 November 2001
In November, NCE reported on ongoing Subway works, and an engineer on the ground gave his first person perspective on what was happening.
Tunnels sealed off with concrete to prevent flooding after 9/11 are to be unplugged to accelerate railway repairs.
Bovis Lend Lease LMB senior vice president Ashlin describes his ongoing work in New York City.
15 November 2001
An NCE source revealed in mid-November that Canary Wharf designers were looking again at their designs following 9/11. Meanwhile, investigations in the US highlighted some key issues.
7 July 2005
In the summer of 2005 the US National Institute of Standards and Technology (Nist) published its draft final report into the World Trade Center collapses. NCE examined the report to bring you the crucial information for engineers to know.
NCE gives a summary of the recommendations made in the draft Nist report regarding tall building design.
NCE lays out what is known about the exact sequence of events that made up the Twin Towers’ collapse process.
22 September 2005
That September, NCE reported on a conference in Washington DC, where disagreements surrounding the Nist report’s findings came to a head. This issue also looked at how the Nist report would affect the future of engineering — and why there was still more to learn.
