Option 2: Bolted temporarily

Answer 1

Metal-framed stairs and landings need to be grouted in place to ensure security and stability.

Step-by-step explanation:

Metal-framed stairs and landings can be used prior to pouring concrete in the pans, but they need to be grouted in place. Grouting involves filling the gaps between the metal frame and the concrete pan with a specific type of mortar, which hardens and provides stability to the stairs and landings. This ensures that they are securely attached and can bear weight without shifting.
