Why it matters here

Frame inspections on Castle Hill builds

Larger two storey replacement homes in Castle Hill carry long spans, laminated beams and hip roofs. The frame findings we record are about how the structure was fixed rather than what it is: strap bracing left slack, laminated members nailed from one side only, walls needing extra support and hip connections the engineer should confirm.

What we find at this stage in Castle Hill

  • Strap bracing not tensioned
  • Laminated beam fixed from one face
  • Wall frame needing more support
  • Hip connection detail unconfirmed
  • Trusses incomplete

FAQ

Frame inspections in Castle Hill: common questions

Why does a slack strap matter?

Strap bracing works in tension. If it is loose, the wall can move before the brace starts doing anything.

What does laminated mean?

Several pieces of timber nailed together to act as one beam. The fixings must alternate from both faces so they share the load.

Should the frame be checked before or after the roof goes on?

After the trusses are fixed, so the roof bracing and tie down can be checked too.

Do you check steel beams as well?

Yes, against the engineering for size, position and connections where they are visible.

Will the builder have to stop work?

No. The report goes to you, and you pass the items to the builder to fix before lining.

How much time does the frame visit take?

Ninety minutes to two and a half hours depending on storeys and complexity.
