Dig started last week. Let me know if you have any queries as I have a slight involvement.
Out of interest, how deep is the excavation? It didn't look like you had the space to dig down to the bottom and then CFA piles in the basement?
How are you maintaining stability of that perimeter wall? Is the wall strong enough to cantilever or are you going to use anchors or struts?
I'm also curious about the steel frame. Are you going for a cellbeam with metal deck for the services, like with the Admiral building?
