Steel’s sustainability role in iconic Barangaroo precinct

Barangaroo precinct sustainability

InfraBuild is helping construct a sustainable and world-class precinct in Australia’s largest city by taking active steps to reduce the embodied carbon in its steel products.

Lendlease’s Barangaroo precinct on the western shoreline of Sydney’s CBD is creating a major urban zone with leading sustainability credentials and world-class amenities.

Barangaroo South’s leadership in demonstrating sustainability initiatives and advanced workplace design has led to it winning several awards, most notably the prestigious Australian Development of the Year award at last year’s Property Council of Australia Innovation and Excellence Awards.

Lendlease said its goal for the wider Barangaroo development is for it to be “the first of its size in the world to be climate positive – that is, to be carbon neutral, water positive and to generate zero waste”.

Already, 89 per cent of all the on-site waste is recycled, reused or repurposed. As a comparison, the average commercial building food court recycles only 25 per cent of its waste.

Steel manufacturer and distributor InfraBuild (formerly LIBERTY OneSteel) played a significant role in the already-completed Barangaroo South precinct through its integrated and collaborative supply of Australian-made reinforcing and structural steel.

InfraBuild Construction Solutions (formerly LIBERTY OneSteel Reinforcing) supplied more than 45,000 tonnes of reinforcing steel product to the Barangaroo South precinct over a 4.5-year supply period. Processes were implemented to ensure a 20 per cent reduction in embodied carbon for the reinforcing steel used, which contributed to the project being awarded a Green Building Council of Australia (GBCA) Six Star Green Star – Communities rating, the highest available. All product was delivered with Australasian Certification Authority for Reinforcing (ACRS) certification.

Barangaroo South’s sheer scale and its CBD location added a layer of complexity that required detailed collaboration between InfraBuild Construction Solutions and the project’s construction partners, including developer Lendlease.

Embracing green renewal

Property Council of Australia Chief Executive Ken Morrison praised Sydney’s newest urban redevelopment, which he said “has recalibrated the way Australians think about precinct-scale urban renewal”.

“Lendlease has combined iconic buildings designed by acclaimed architects with world-leading sustainability initiatives that have transformed entire supply chains and challenged large tenants to embrace green business practices,” Morrison said.

With the southern precinct now complete, attention has turned to the landmark Crown Sydney project at the northern end of the Barangaroo site, with InfraBuild supplying 2500 tonnes of structural steel, welded beams and plate to what will be Sydney’s tallest habitable building when it tops out in 2021.

Engineering for humanity and liveability will be explored in detail at the upcoming World Engineers Convention 20-22 November in Melbourne. To learn more and to register, click here.
