Inspection at a Glance
This inspection was conducted at a critical construction milestone before the builder may proceed to the next stage.
Builder must rectify all non-compliances and obtain sign-off before proceeding to the next construction stage.
Outcome relative to NCC compliance requirements and the structural engineer's specifications.
Inspected strictly to National Construction Code and applicable Australian Standards for this stage.
What We Found on Site
Below are key observations documented during this physical visual assessment. Each defect is rated by severity, accompanied by photographic evidence and trade recommendations.
Wall & Roof Framing — Post Alignment
Inspector note: Timber structural post misaligned — out of plumb breach of NCC tolerances — builder rectification required.
Main timber structural post was misaligned and noticeably out of plumb, breaching National Construction Code (NCC) tolerances for vertical stability.
An out-of-plumb load-bearing post creates eccentric loading on the concrete footings, increasing stress on adjacent frame connections and causing cracking in finishes once upper-storey weight is applied.
Builder must release fixings, pack/re-plumb post using laser level, and reinstall engineered tie-down brackets prior to insulation and lining.
Structural Beams & Bracing
Inspector note: Wall frame bracing incomplete — tension straps require correct fixing before progress to wrap stage.
Bracing tie-downs and strap tensioning were incomplete on several load-bearing external wall panels.
Wall bracing provides shear resistance against high wind loads across South-West Sydney. Incomplete fixings compromise the lateral rigidity of the entire dwelling.
Builder must complete all strap tensioning and fixings strictly to the structural engineer's bracing layout.
Protecting Your Build at Critical Milestones
Conducting an independent third-party frame inspection in NSW ensures that your builder adheres strictly to AS 1684 (Residential Timber-Framed Construction) and the National Construction Code (NCC).
In this Leppington case study, our detailed defects report gave the owners documented evidence to issue to the builder prior to releasing the Frame Stage progress payment. The builder promptly re-aligned the structural posts and completed the bracing schedule, ensuring long-term structural integrity.
Takeaway for Build Owners & Investors
Staged frame inspections are the single most critical safeguard when building a home. Once wall cavities are sheeted with plasterboard, structural out-of-plumb defects are hidden forever, causing permanent floor squeaks, door binding, and uneven load distribution.
