DESCRIPTION
This is the presentation used for the third of our tensile fabric webinars, a refresher programme for architects. Webinar 3 is called 'London 2012 Games Case Study - The Basketball Arena and Shooting Ranges' and offers a behind the scenes look at how these two very different temporary structures were created - from initial design through to installation and completion. The Basketball Arena was the largest temporary structure ever created for an Olympic Games and also the quickest structure to be built on the Olympic Park. The Shooting Ranges comprise of three cutting edge architectural masterpieces, unique temporary structures designed to leave no lasting trace after the event. You can also watch recordings of the narrated webinar series, simply visit www.basestructures.com/portal/tensile-fabric-webinars.html.
