Fire proofing of ceiling above foyer

Hi,

We are currently in the process of moving from Company Title to Strata and are getting the building up to standards. It is a 4 unit art deco.

We are aware that one of the stipulations is that the ceiling above the entry foyer needs to be a fireproofed material. Does anyone know where this specifiaction can be found in the BCA? We are in NSW.

Thanks!
