FAQ

Frame inspections in Donnybrook: common questions

Why does frame matter more than the rest?

It is the final point at which structure is visible. Everything after it is concealment.

What is wrong with skew nailing a porch post?

It is not a tie-down. A post carrying roof load needs a fixing rated for uplift, and skew nails are not that.

Do you check the trusses?

We check support, fixing and bracing, and we record any chord that has been cut. Certification of the truss design comes from whoever fabricated it.

What if the builder disputes it?

Each finding cites the drawing or the standard, which makes it a factual discussion.

Which standards apply?

AS 1684 for timber framing, with AS 4055 governing wind classification.

Can any of this be seen later?

Not without opening walls, which is the entire reason for the stage.
