The columns get backed up with new 2.5 foot by 5 foot thick concrete buttresses from ground level to about 10 or 15 feet below the top of the wall and beams will be added at the top of the buttresses back to the wall. The old raker beams (sawtooth beams running up at an angle that used to support the seating) will remain way up high between the columns backed up by the buttresses and the old wall. Everything west of those buttresses goes away after the buttresses cure...columns, raker beams etc, and the new seating will be 100% new construction in that space.
Thanks for the info. I've been very curious about how they planned to support the wall.
