Major excavation works at Martin Place are nearing completion as construction progresses on the new Sydney Metro underground metro station and integrated station development.

Excavation began around one year ago and has led to 151,000 tonnes of rock being removed, enough to fill 25 Olympic sized swimming pools.

Since works began, 51 anchors have been installed underneath 50 Martin Place to secure the sandstone under the historic building’s footings.

Canopy tubes have been installed in the northern pedestrian link tunnel to support the structure in preparation for when the new walkway is tunnelled.

Workers have also completed a 19-metre-long escalator tunnel as one of the future entrances to the Martin Place metro station.

The milestone has exposed a new view of Sydney Tower and the MLC Centre – from 19 metres deep under Martin Place.

Seven weeks of work was undertaken to excavate the tunnel. It will house four escalators for customers as they travel to the new underground metro station.

For this tunnel more than 2000 tonnes of crushed rock was removed and 700 tonnes of shotcrete was used to line the tunnel.

The new station will provide customers with direct access to the City and Southwest line upon its opening in 2024.

Macquarie Group is delivering the new Sydney Metro Martin Place integrated station development and has appointed Lendlease as its design and construction contractor.
