Ground investigations underway for Melbourne Metro Rail

Geotechnical works for the Melbourne Metro Rail project in Australia have commenced.

Ground investigations are due to start this week along the Swanston Street alignment that will carry train services under the heart of the city.

The geotechnical work will provide critical information about ground conditions and soil quality, which will inform the precise alignment, depth and design of the new rail tunnels and underground stations.

The ground investigation programme, which will be completed in two stages, includes approximately 140 boreholes cross the project from South Kensington to South Yarra.

The first stage of investigations requires boreholes in the Arden and Lloyd Street areas, CBD and Swanston, Street Domain Parklands, and Domain Interchange.

The second stage of the investigation programme will provide more detailed information to assist in further development of project designs. It will also include boreholes in areas requiring further assessment.

Site investigations will continue until mid-2016 and major works are expected to commence by 2018.
