Factory Mutual metal deck span limits
Factory Mutual metal deck span limits
(OP)
Is there any reason to pay attention to the (more restrictive) metal deck span limits from Factory Mutual for normal commercial construction? The CSI deck catalog I have gives them in their tables and they have a Factory Mutual approval guide at:

I've only had to work with Factory Mutual requirements one time at an industrial facility and this is the first time I noticed it in deck catalog.

I still try to limit my spans in all buildings to similar maximums even though we are using rubber membranes on most roofs today.

It is FM's attempt to control and minimize claims by stepping into the design of buildings and ensuring a level of conservatism in construction of their insured buildings.
If you owner isn't covered by an insurance company that requires this, then you don't need to follow it....unless you want to as its provisions are usually pretty good.
