I perform many takeoffs for industrial projects. One of the significant differences between commercial and industrial work is the feeders, which can account for more than 80 percent of the time needed to complete the takeoff.

My first exposure to material pricing was in the mid-1970s when I was promoted to pricing clerk/assistant-purchasing agent at a wholesale house.

The prices were updated weekly with new pages in a packet from Trade Service. READ MORE
