Why it matters here

Frame inspections on Berwick builds

Larger Berwick homes lean on engineered parts: girder trusses, steel beams, posts and bolted connections. That is where our major findings sit, from packers under girders to bolts smaller than the engineering asks for.

What we find at this stage in Berwick

  • Packers under girder trusses not rated for the load
  • Bolts in engineered connections undersized
  • Bottom plates overhanging the slab edge
  • Roof brace splices too short
  • Posts split by coach screws
  • Loadbearing junctions cut for plumbing

FAQ

Frame inspections in Berwick: common questions

Why do packers under a girder truss matter?

A girder carries other trusses. Cement sheet packers are not rated to take that point load, so the support may crush over time.

How do you check a bolt size?

We measure the installed bolt with calipers and compare it with the engineering detail for that connection.

What overhang is allowed at the slab edge?

Generally no more than 10mm under the bottom plate. Beyond that the plate is not bearing fully on the slab.

Do you inspect the trusses themselves?

Our frame visit covers how trusses are supported, fixed and braced. The truss supplier is responsible for the truss design.

Which standards apply?

AS 1684 for timber framing and AS 4055 for wind loads, alongside the engineering for your lot.

Can these be fixed easily?

At frame stage, usually. Once plaster and ceilings are up, most require removing linings.
