BHP Iron Ore – Camp Accommodation Security Door Replacement Project

The project involved the large-scale replacement of accommodation security doors, requiring stringent quality control to ensure compliance with BHP’s operational and durability standards.

Incon’s scope included:

• Inspection of door fabrication and assembly processes
• Assessment of manufacturing quality, tolerances, and finishes
• Identification of defects impacting structural integrity, durability, and installation
• Development of quality assurance benchmarks and acceptance criteria
• Coordination with manufacturers and stakeholders to ensure compliance

A detailed inspection regime was implemented covering frames, welds, coatings, lock installations, and assembly components.

• Inspections identified inconsistencies in fabrication quality, including incomplete welds, coating defects, and dimensional tolerances impacting performance.
• Inadequate surface preparation and coating defects created risks of early corrosion, particularly at welded joints and exposed steel elements.
• Issues such as misaligned locks, excessive gaps, missing fixings, and poor surface finishes impacted installation efficiency and operational reliability.
• A lack of clearly defined acceptance thresholds across “Good / Fair / Poor / Very Poor” conditions created ambiguity in defect assessment and rectification requirements
• Large volumes of doors required consistent inspection methodology and repeatable assessment criteria across multiple batches and suppliers.

Incon implemented a structured engineering and QA framework to address manufacturing and performance risks:

• Developed comprehensive checklists covering all components including frames, welds, coatings, locks, and fittings to ensure consistent assessment across batches.
• Established clear acceptance standards linked to structural performance, durability, and service life, including:
• Continuous weld requirements to prevent structural weakness
• Coating integrity to mitigate corrosion risks
• Dimensional tolerances for proper installation and operation
• Applied a tiered quality classification (Good / Fair / Poor / Very Poor) to prioritise rectification actions and align with BHP’s compliance framework.
• Identified key failure modes including:
• o Inadequate weld continuity
• o Poor powder coating application
• o Improper finishing and handling during fabrication
• o Assembly and fitting inconsistencies

The project delivered significant value to BHP through:

• Improved quality control and consistency across manufactured door batches
• Reduced risk of premature corrosion and structural degradation
• Enhanced installation efficiency and operational performance
• Establishment of a repeatable QA framework for future projects
• Increased confidence in asset durability and long-term serviceability

Incon’s engineering-led approach ensured that quality assurance was directly aligned with structural performance, resulting in a robust and reliable outcome for critical accommodation infrastructure.
