Detailed Evidence Log

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.

1
Inspection Area

Wall & Roof Framing — Post Alignment

Major Defect
Timber structural post misaligned — out of plumb breach of NCC tolerances — builder rectification required.
EVIDENCE #1

Inspector note: Timber structural post misaligned — out of plumb breach of NCC tolerances — builder rectification required.

What We Saw

Main timber structural post was misaligned and noticeably out of plumb, breaching National Construction Code (NCC) tolerances for vertical stability.

Why It Matters

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.

Our Recommendation
Trade: Licensed Builder / Framing Carpenter

Builder must release fixings, pack/re-plumb post using laser level, and reinstall engineered tie-down brackets prior to insulation and lining.

2
Inspection Area

Structural Beams & Bracing

Major Defect
Wall frame bracing incomplete — tension straps require correct fixing before progress to wrap stage.
EVIDENCE #2

Inspector note: Wall frame bracing incomplete — tension straps require correct fixing before progress to wrap stage.

What We Saw

Bracing tie-downs and strap tensioning were incomplete on several load-bearing external wall panels.

Why It Matters

Wall bracing provides shear resistance against high wind loads across South-West Sydney. Incomplete fixings compromise the lateral rigidity of the entire dwelling.

Our Recommendation
Trade: Framing Carpenter

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.

Inspector's Final Synthesis

Takeaway for Prospective Buyers

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.
