I'm putting together some stuff (pictures, NIOSHA report and some info from American wood and paper Association) for a training I'm attempting to do on Lightweight Construction dangers and spotting this type of construction. I got some pictures from a strip mall being built in our area of for some good views of void space and such but am looking for something to help me build my presentation. If you have done a powerpoint or such a training I would like an info you are willing to give.
