How Britain Raised 315 Metre Wembley Arch Off the Ground in 3 Weeks

The Wembley arch: 315 metres of steel spanning a stadium, 133 metres tall above the north stand, weighing 1,750 tonnes, made from a lattice tube 7.4 metres across, which is wider than a Channel Tunnel train. It was assembled lying flat on the ground, then jacked from 0 degrees to 112 degrees over about 3 weeks starting on 3 June 2004, with a full survey taken every 5 degrees of rotation. And it is not decoration. It carries 100 per cent of the north roof and around 60 per cent of the south. This documentary covers the full engineering and construction process, from the sightline problem that rules out columns in a 90,000 seat bowl, to the reason a compression arch is built as a hollow lattice tube rather than a solid member, the buckling failure mode that makes diameter matter more than weight, the concrete foundations resisting an outward thrust that never goes away, the cable system that must stay in tension even when wind is lifting the roof, and the erection principle that the governing design case is often a moment during construction and not the finished structure. Why the arch leans 22 degrees. Why three different published weights are all correct. And why nobody can tell you how many days the lift took.
