In short: Bolts absent at steel posts and beams on Leppington frames.

Where the load goes

In a mixed timber and steel frame, the steel carries the concentrated loads and the connections carry the steel.

What we recorded

Bolts missing at steel posts on Leppington frames, and separately a connection built differently to the engineering.

Why it survives

Steel reads as finished from a few metres away whether or not the bolts are in, and nobody counts them once the linings go on.

What we need

Your engineering. Without it a report can describe the steel present but not confirm it against the design.

The fix

Straightforward at frame stage, while the connection is exposed and the fabricator is still involved.

FAQ

Questions Leppington owners ask about this

Is it dangerous now?

It is a structural non conformity rather than a hazard today. It matters under the load the connection was sized for.

Who is responsible?

The builder, as the party building to the engineering, with the fabricator and erector behind them.

Would a certifier catch it?

Their inspections serve the certificate rather than acting as a defect inspection.

Can it wait until after lining?

It can be done, at considerably more cost and disruption. At frame it is an hour.
