Why it matters here

Frame inspections on Tallawong builds

A double storey on a narrow Tallawong lot relies on its bracing walls and tie downs far more than a wide single storey does, and upper floors add steel posts, beams and connections to the engineering. The items that matter are small and specific: a tie down bolt left out, strap bracing not hooped over the plate, a bottom plate cut through in a bracing wall, a column connection that departs from the engineer's detail.

What we find at this stage in Tallawong

  • Tie down bolts at every bracing wall
  • Strap bracing tensioned and hooped over plates
  • Plates continuous in bracing walls
  • Post, beam and hanger connections to the drawing
  • 15mm clearance above window heads

FAQ

Frame inspections in Tallawong: common questions

What is a tie down bolt?

A rod that anchors a bracing wall to the slab so the wall cannot lift or rack in wind. The engineering shows where each one goes, and a missing one leaves that wall relying on nails.

Why must strap bracing hook over the plate?

The strap resists racking only if it is anchored at its ends. Hooping it over the top plate and nailing it there is how AS 1684 makes that anchor work.

Can a plumber cut a bottom plate?

Not in a bracing or loadbearing wall without an approved repair. A cut plate breaks the load path the wall depends on.

What if a connection does not match the engineering?

The builder either corrects it or gets written engineering approval for what was built. We record which drawing detail it departs from.

How long will the frame inspector spend at a Tallawong double storey?

Two to three hours on a double storey, depending on access to the upper floor.

Will you check the frame items again later?

Yes. At lock-up each frame item is marked fixed or still open so nothing is lined over unresolved.
