The changes in FM are significant. We're doing a office with parking garage job that is FM Global. We have to do two submittals, one for the city using NFPA area density and the other using the new FM area densities. FM design for a parking garage is .3/1000. And as near as we can tell FM doesn't recognize any of the twin tee rules from NFPA. 22 inch deflector max, period. It's a real pain trying to comply with both.

Add to the mix the radical change that FM now applies by only using a defined number of sprinklers and a starting pressure for all sprinkler types. This concept was proposed to the 13 TC and was soundly rejected. I just don't see 13 doing away with the area/density curves. Keeping in mind that truth can be stranger than fiction and you never really know where a group of 30 voters is going to end up, for the foreseeable future, I believe the odds are about the same as a snowballs chance in hell.
