Rated barrier walls and shafts were designed by registered Architects when buildings were constructed.  As-built MEP drawings were created. As new projects were either designed or completed, new as-built drawings were created. Over the last few decades, unstamped life safety drawings were created and used for regulatory audits. Frequently, these drawings have become the drawings building managers use to make decisions. These drawings don't always match the original "stamped" permitted drawings. Life safety items that exist in the ducts, door that have ratings and walls that are built with either one or two layers are seen, but do not match what the new unstamped life safety drawings are showing.

Egis Corporation (Florida) documents these barrier conflicts. We interact with clients and other vendors responsible for making changes. We identify, track and share conflicts in our Procore program.
