Leadenhall Building

Leadenhall Building

(OP)

I caught a video, I think on PBS, about this building.
It was erected in (crowded) central London, with no hotwork in the sky, with the basic structure going up at what I recall as one floor per day.
The basic structure comprises stacked 'tables', each comprising four one-story columns, two short beams, and two long beams, welded into a unit and painted in a factory (where utilities like piping and electrical distribution were also installed), trucked downtown, hoisted into place, and bolted to the table below.
To deal with 'trajectory error' (my term, I forget what CEs call variations in perpendicularity to the ground), they jacked and shimmed the joints in an external bracing structure comprising only diagonal members.

Quite an interesting building.
FYI.

RE: Leadenhall Building

Thanks for the link, it looks like a very interesting building. I'll admit that it makes me wince a bit to see a high-rise owner touting the lack of internal columns as the last one of those -- excuse me, the last twin pair of those -- that used to make that claim are no longer standing. Presumably that situation's been studied in great detail and we've learned from it, though.

It sounds like it was a state-of-the-art design and construction.
