Reporting functionally to the O&M; Readiness Director and Defect Manager, you will work closely with our Engineering, Maintenance, and Commercial teams to identify, risk‐assess, and verify the close‐out of design, installation, and commissioning defects.
You will provide vital O&M-focused; technical assurance, ensuring that building services,



tunnel ventilation, fire and life safety, and electrical assets are safe, compliant, maintainable, and fully documented before entering service.
Prior to Trial Operations
Provide O&M; and maintainability input into MEP design reviews, Testing & Commissioning (T&C;), and progressive asset acceptance activities.
Coordinate and technically support MEP defect governance, ensuring that defects, non‐conformances, and incomplete works are evidenced, risk‐assessed, and tracked.
Conduct inspections, physical walkdowns, and technical readiness reviews across all stations, tunnels, precincts, and the Orchard Hills Stabling and Maintenance Facility.
Review complex handover packages, verifying that as‐built records, warranties, statutory certificates, and configuration details satisfy O&M; requirements.
Support the Asset Manager – Facilities Management in establishing maintenance task lists, asset hierarchies, statutory inspection regimes, and configuration data within Maximo.
During Trial Operations and Transition to Operations
Manage outstanding MEP defects during the Defects Correction Period, ensuring that rectification evidence is technically verified and closed out contractually.
Perform engineering risk assessments, review design changes, and manage concessions or temporary arrangements affecting MEP systems.
Support engineering investigations, risk mitigation forums, and root cause analyses for any repeat, systemic, or safety‐critical MEP failures.
Ensure a structured, traceable, and clean transition of all outstanding defects, residual risks, and warranties to the permanent operational team upon project completion.
