The Challenge
The client needed a partner that could provide robust program and risk management across a multi-billion-dollar program with numerous contractors, tight urban constraints, and first-of-a-kind elements — including tunnelling under Sydney Harbour and through the CBD. Coordination between design, procurement, and construction had to be seamless to protect schedule and avoid cost escalation.
- Multiple major design-and-construct contracts running in parallel
- Interface management across tunnel, stations, systems, and existing rail
- Stakeholder and community expectations in a high-profile corridor
- Geotechnical and construction risk in variable ground conditions
Our Approach
We embedded a dedicated delivery management team within the client organisation, providing program controls, risk and opportunity management, schedule analysis, and independent assurance. Our team worked alongside the client’s technical and commercial leads to support decision-making and drive performance across the supply chain.
Program controls
Integrated cost, schedule, and change management with clear reporting and forecasting.
Risk & assurance
Structured risk registers, quantitative analysis, and independent reviews at key gateways.
Interface coordination
Alignment between tunnel, stations, systems, and existing network operators.
Results & Impact
The Sydney Metro City & Southwest line opened to passengers as planned, delivering a step-change in capacity and reliability for Sydney’s rail network. Our delivery management support helped the client maintain visibility and control across the program and make informed decisions at critical points.
