I have a contractor that is bidding on a design/build for a new mill. One of the buildings is a mill building that will house an 80 ton class F crane. This thing is 82 ft high and 76' wide and they want the frames on 30 ft centers.
Anybody have a feel for what drift should be allowed due to wind/seismic. H/400 is less than 3 inches and I'm having a hard time making that happen.
