The first major demolition work has finished at Pitt Street Station, one of Sydney’s new CBD metro railway stations.
Eight buildings have been removed for the northern entrance of the new Pitt Street Station – the highest, 14 storeys.
Over the past seven months, crews have gradually brought down buildings on Castlereagh, Park and Pitt streets floor by floor, with excavators craned as high as 51 metres to carry out demolition from the top down.
During demolition, 21,000 tonnes of concrete, 5,500 tonnes of bricks and 570 tonnes of steel were all recycled.
Concrete columns are now being installed to form a retaining wall at the Pitt Street site so excavation can take place up to 20 metres below the surface.
An acoustic shed will be built to minimise the impacts of construction noise on surrounding businesses and residents.
Work is also starting to demolish four buildings on Pitt and Bathurst streets to make room for the southern entrance to Pitt Street Station.
The first of five mega tunnel boring machines will be in the ground before the end of the year to build the twin railway tunnels between Chatswood and Sydenham.
Pitt Street is one of 31 stations on Sydney Metro, with customers to have new and direct access to Sydney’s north west and south west on fast, safe and reliable metro trains in 2024.
Sydney Metro services start in the first half of next year in the city’s North West, with metro rail to be extended under Sydney Harbour, through the CBD and beyond to Bankstown in 2024.
