i work for a company that fabricates steel. mostly stairs, rails, structural collums and beams. most recently ive been to the big house, and Ross school of Buisiness but we have had a crapload of work there over the years (last big one was the new cardio-vascular center at the hospital) I usually do the actual fabrication, but one of my other jobs for the company is a contractors rep. so I have to go out to the jobsites, and take field measurements. that way our draftsmen and engineers can design the stuff correctly.
