1.0 Executive Findings & Compliance Index

This comprehensive building condition audit for Lot 42, 18-24 Barangaroo Ave, Sydney NSW was conducted strictly in accordance with AS 4349.1-2007 (Commercial Annex B) & NCC 2022. Our visual, non-destructive, and computer-vision-enhanced survey identified 3 distinct defect item(s), comprising 2 Major Structural/Serviceability Defect(s) and 1 immediate Safety Hazard(s). Forensic imaging analysis indicates active building envelope compromise. The identified structural and weatherproofing anomalies represent significant statutory non-compliances under NCC 2022 Volume 1 & 2. Immediate remediation works are required to arrest accelerated reinforcement carbonation and water ingress. Total estimated rectification liability across all tagged items is currently projected between $25,700 AUD and $39,700 AUD (excluding GST and professional engineering certification fees).
