TAC BC Talk: North East Link Motorway Scheme
Presentation Abstract:
As part of Victoria’s Big Build, the North East Link motorway scheme (the Project) is being designed and constructed using the PPP process by the SPARK consortium (SPARK CJV). North East Link will provide a new freeway standard connection between the M80 Ring Road and an upgraded Eastern Freeway, completing the missing link in Melbourne’s metropolitan ring road. It will give the city a fully completed orbital connection for the first time. The project includes Victoria’s longest twin road tunnel, Melbourne’s first dedicated high-speed busway, new public open space and extensive walking and cycling links. Delve Underground have designed the twin TBM tunnels, ventilation tunnels, SEM tunnels and cross passages for the project, as well as a number of cut & cover and ancillary structures. The presentation will focus on the SEM (Sequential Excavation Method) tunnels being constructed and detail the geotechnical conditions, analysis of support and excavation sequence and also construction. These SEM tunnels are 20 m wide with heights of 15 m excavated into very heterogeneous siltstone/sandstone rock with faults and deep weathering.
