Highest job built from the ground up was 29 x 2m lifts with a 3m base lift.
Funnily enough I did work on Canary Wharf...
Not when it was being built, but we did a truss out scaffold for the abseil that was done on it a few times. Was on record breakers a few years ago.
This was built of the roof just where the pyramid starts.
I think I remember watching that, was it some bird that broke the record?
