Twin towers

Robert Benaim structural engineer Jim Paterson decided he would retain the top portion of towers using oil rig technology.

'The existing 'twin towers' aren't towers at all,' he insists. 'They are only stumps. Jack them up in the air using North Sea oil platform techniques so they become real towers.'

He suggests building new steel towers on the square concrete buttresses at the corners of the existing ones. A steel ring beam under the towers' octagonal domes could be fitted with jacks.

These would lift the domes by pushing against a steel jacking tower assembled inside the structure. Once at the top of the new towers the domes would be braced and what was left of the old stadium demolished. Underpinning at basement level would support the new towers.

Paterson believes his solution would cost 'in the region of £4M to £5M and would take 9 to 12 months to complete, including all the necessary planning approvals and design time'.
