Sample Item #8 Question - CSI MasterFormat

    Div 7 is moisture and thermal protection. So the metal panels can be assumed to be a rain screen. Even though they are metal, and you might think they go in Div 5, they are acting as moisture protection and go in Div 7. Precast concrete panels would more likely go into Div 3 because they are structural concrete.

    Hi Paul, just a quick correction: precast concrete panels are not necessarily structural or load-bearing; often times, they are nonstructural and are supported off steel/concrete framing just as a curtain wall would be. 

    Per MasterSpec, precast architectural concrete is specified under section 03 45 00.
