AI-generated summary
Two workers died when dongas (temporary accommodation buildings) were destroyed by Tropical Cyclone George at a remote mining camp 90km south of Port Hedland in March 2007. The buildings were designed and constructed to non-cyclonic Wind Region A standards when they should have been built to cyclonic Wind Region C standards. A series of cascading errors occurred: the original tender documentation incorrectly specified Wind Region A, the builder NT Link failed to verify the correct wind region despite having coordinates and measurement capability, inadequate tie-down designs were provided without engineer certification, an unqualified welder performed critical welds, and the Shire's building surveyor incorrectly approved the Wind Region A specification. Had proper Wind Region C standards been applied with appropriate tie-downs and certified welding, the dongas would have withstood the cyclone. The preventable deaths highlight systemic failures in construction compliance driven by time pressures and inattention to detail.

Error types
Contributing factors
- Dongas designed and built to non-cyclonic Wind Region A standards instead of cyclonic Wind Region C
- Inadequate tie-down design lacking engineer certification
- Tie-downs welded by unqualified welder (Trent Lees, non-ticketed)
- Substandard welding quality on multiple tie-downs
- Builder NT Link failed to verify correct wind region despite having coordinates
- Building surveyor Chad Harvey incorrectly approved Wind Region A specification
- Missing tie-down specifications in building licence application
- Inadequate oversight and quality control during construction
- Time pressures prioritized over construction compliance
- Lack of written procedures for wind region determination at Shire
Coroner's recommendations
- Western Australian Government should consider introducing mandatory inspections in Wind Regions D and C in order to achieve greater construction compliance with the applicable building standards set out in the Building Regulations 2012
- Australian Building Codes Board should explore methods by which a large scale electronic map prepared in accordance with the smoothed coastline and the delineated wind regions be made accessible through the Web, to be updated if and when Australian Standards change the delineated wind regions
