Regional Rail Link is a landmark award-winning infrastructure project designed to remove bottlenecks in Victoria’s rail network. It will separate metropolitan and regional trains to improve reliability and offer new services to the growth areas in Melbourne’s west. It will also free up critically needed space on other suburban lines.
The project was Victoria’s highest priority project for action submitted to Infrastructure Australia and was jointly funded by Federal and State Governments.
The project includes dedicated regional tracks allowing regional services to run directly into Melbourne, including three new stations at Wyndham Vale, Tarneit and West Footscray and major upgrades to Sunshine and Footscray stations. Two new platforms at Southern Cross Station in Melbourne and the construction of a major new rail bridge over the Maribyrnong River will also provide further capacity.
45km of new track
The KBR Arup (KAJV) design joint venture was awarded the concept design for the entire alignment, which was then extended to the development of reference designs and technical advisor support for both the procurement phase and subsequent construction phase. The $3.9bn project comprises 45km of new rail track, 25 bridges, five new upgraded stations and five grade separations within the operational rail corridor.
The co-located, multidisciplinary design team worked in tandem with the client and stakeholder organisations to investigate options at concept design stage which included possible tunnel alignments, alternate grade separation configurations and elements of early works to expedite project delivery. The reference design we delivered was largely carried through to the final design and construction, underlining the robustness of the early design stages.
The strong working relationship developed between RRLA and KAJV from the onset resulted in a robust, well-considered and effective reference design that went out to market for delivery. Consequently the KAJV reference design remained largely unchanged by the tenderers and was one of the key contributors to the project’s success. KAJV were professional and flexible in their approach and responded to every challenge we asked of them. ” Brendan Driscoll Director Engineering, Regional Rail Link Authority
Contributing more than 15 engineering services to this project over more than five years our multidisciplinary design will benefit many by improving reliability of the train network and offer new services to growth areas in Melbourne’s west.
KAJV successfully delivered the concept design for the entire 50km alignment within 140 days of appointment to meet deadlines critical for the overall viability of the project. We subsequently provided options appraisal, preliminary design, detailed design, site investigation and early works coordination.
Our role was extended to provide technical support throughout the procurement and construction phases.
To realise the early delivery of critical elements of the project alignment, our team were well placed to effectively carry out final design and documentation for new rail infrastructure prior to appointment of the main construction packages.
The effort expended at the concept and reference design stages of the project, and continued technical support throughout the procurement and construction stages, has been instrumental in a highly successful project outcome and delivery of new rail infrastructure for the state. ”Allen Garner CEO, Regional Rail Link Authority
