I underlined the part above, just because I wanted to bring it to Che's attention, and ask him if he and/or his co-workers would/have done such a thing?
I think that picture was taken by a professional photographer and the guys were sitting on the beam just for the picture , there is not work for 11 guys at the same spot on a connecting crew (4 guys max ).
The picture gives the illusion that the guys are sitting on a exterior beam 800 feet on the air and if they fall the would go all the way down to the ground (street),
My experience tell me they are sitting on a interior beam with a completely decked floor ( 2 floors )below them.
there is no reason for taking break sitting on a freaking beam.
My coworkers and I wouldn't have any problem sitting on a beam like those guys in that pic.
