Lightweight Construction - Failure Under Fire

This is a documentary video project I made back in 2005 for a class I took at Glendale College (Fire115 - Building Construction). The second half if the video includes a test burn comparing lightweight and conventional floor construction under a load. *Note to commenters: I realize that this experiment is not scientific. It is a purely observational exercise, but I still feel that there is knowledge that can be gleaned here.
