Cross River Rail is a 10km rail line between Dutton Park and Bowen Hills which includes 5.9 kilometres of tunnel under the Brisbane River and the CBD, 4 new underground stations and 2 upgraded stations. The project aims to unlock the bottleneck at the core of Brisbane’s transport network and it will transform travel across the whole of South East Queensland.

Through the Planning Phase for the Southern Tunnel Portal Construction and Junction Reconfiguration Works, Rail Planning Services were engaged as a multi discipline SME team to achieve a realistic construction approach to a defined program with minimal impact to existing operations.

To achieve this, our team reviewed the head contractor’s scope, construction methodology, program and proposed operational impacts during construction for suitability against industry benchmarks. As part of this review, our team developed schedules in support of constructability review of the proposed portal designs (Primavera P6 Schedules), including a complete Forensic Analysis of the Primavera P6 construction schedule and report findings. The review also included alternative scoping options for additional works required at Dutton Park Station; of where detailed construction staging diagrams, construction program and construction methodologies were produced.
