With the scaffolds I have seen everywhere, I am of the belife that all Builders should have to sucessfully complete 3 hangers, 3 stand alone, and 3 multi angle slope bottom tanks out of BETCO. All of them have to be at least 3 lifts tall. In order for them to count as sucessful, they must be completed in a timly mannner, plumb, square, and level. I shutter to see scaffold in the public area such as side walks that are crooked, unlevel and missing basic parts. Just a thought for improving the industry.
