I would say that they are starting from scratch. They have pulled new conduit through the existing roof under what will be the whole footprint for plumbing, electricity, etc, have installed elaborate rebar on top of the roof and have been pouring a huge concrete slab,…I think at least 30cm thick. The crane base is there and will be cemented in during one of the pours
Up to this point, they were underpinning in the existing structure. A lot of that work, which was substantial has occurred out of sight
