Essentially the entirety of the cores were cast in place (so all the walls of the six main structures) plus the slabs/floors, whilst all of the rakers, terraces and vomitory walls were precast.Anyone know how much of the concrete is precast vs cast in place? I did concrete work for 10 years and would shudder to think of having to do all of that cast in place.
There was a question over whether the rakers for the South end of the East stand (which couldn't be put into place in sequence due to the old Paxton being in the way) would be cast in place, as the overhanging tier would get in the way of installing a precast unit. But, we're still to see on that one I think; I would be surprised if they weren't precast though.
