Construction firm Multiplex has wrapped up the work on the new tower and retail precinct at 80 Collins Street, located in Melbourne’s CBD, Australia.

In May last year, QIC Global Real Estate sold the 80 Collins Street precinct to Dexus and Dexus Wholesale Property Fund.

The precinct, which is situated at the “Paris end” of Collins Street, features a new 38-floor office tower offering about 43,000m² of premium office space and a 255-room hotel as well as major improvements to the current 47 level A-grade office building.

Woods Bagot has designed the base building in partnership with Dutch firm UN Studio on the facades of both the new office tower and hotel.

The project includes several sustainable features to achieve WELL readiness and a 6-Star Green Star rating for the base building.

The extensive retail precinct sprawls across the ground and podium levels while the three surrounding streets – Collins, Exhibition and Little Collins streets – are linked via a series of laneways, connecting the new hotel to the office towers.

Multiplex regional managing director Graham Cottam said: “We are proud to deliver this new landmark development to Collins Street, it is an exciting new addition to Melbourne’s premium retail and office precinct and breathes fresh life into the rich history of the area.

 “80 Collins Street was an extremely complex build with the new office tower constructed to cantilever 12 metres over existing buildings on Collins Street, the first time this engineering feat has been achieved on such a scale.

“It is built to withstand 30,000kN tensile force through the concrete core, which is three times that of what has been previously built in Australia.”

Construction on the project started in April 2017 with some 800 workers on-site every day in peak periods and about 7,000 tonnes of structural steel and 30,000 cubic metres of concrete used throughout construction.
