What it is
The steel rods that tie the roof framing down to the slab are loose.
Why it matters
They stop the roof lifting in a storm.
How we check it
At frame stage we check every tie-down against the engineering drawings.
The fix
Re-tension every rod and check the connections.
How common it is
One of the frame-stage items that's invisible once the plaster goes on.
The standard
AS 1684.2:2021, 1.15 and the approved engineering drawings
