Party wall detail in Schofields NSW

Where two dwellings share a wall, that wall does several jobs a normal wall does not. It separates fire. It carries a damp proof course that has to run continuously so moisture cannot cross between properties. And every service that penetrates it breaches the separation it provides, which only a rated sealant reinstates. On Schofields lock-up inspections we recorded damp proof course detail twice and fire rated sealant once, and by the time the linings are on none of it can be checked by anyone.
