Sliding the towers

Twin towers

Last week underpinning specialist Abbey Pynford met Wembley National Stadium Limited to discuss the feasibility and costs of sliding the towers to a new location, perhaps to form a gateway to the new stadium.

The move would have to be carried out by first transferring the load of the towers onto prefabricated steel frames inserted under each tower above a concrete raft.

The rest of the columns which previously supported the jacked up structure can then be demolished. The towers would then be jacked down onto the raft which is supported by concrete slide beams cast at ground level.

Raft and towers would be raised by jacks. Grease skates would then be installed between the raft soffit and the slide beams. The raft would then be pushed along the beams by jacks pushing against a thrust beam bolted across the slide beams.
