What is going to happen to the wall that remains? Will it be rebuilt with masonry, EIFS, or will a new building be attached to it?
The last one we did, we stopped our demo one set of columns away from the point of the building that was remaining. We left that row of columns in place and cabled the columns for shearing. A new masonry wall was built to the underside of the existing columns. We then went in and removed that last part of the structure.We had to use some shoring in some areas where some beams were in place over windows.
Keep in mind that this was done with a demising/shoring plan.
If you already own the work, at least get an engineer to take a look.
Oh yeah, we also had to weld some reinforcing steel inside the building that was remaining.
The other thing that is a real big concern will be weather protection.
