Marr and Mirvac remove first section of iconic TV tower
Australian crane company, Marr Contracting (The Men From Marr’s), in partnership with Mirvac, has successfully removed the top section of one of Sydney’s highest and most recognisable structures, the former TCN-9 TX transmission tower at Willoughby. Built in 1965, the lattice ‘Eiffel Tower’ was Sydney’s first television tower and one of three towers known as ‘the Artarmon triangle’ that broadcast television on behalf of major media companies before being decommissioned in February 2021. With the departure of Nine Entertainment Co to North Sydney, Mirvac acquired approval to remove the tower and redevelop the site into a new residential community. At 233-metres, the tower, which was Sydney’s tallest structure until Sydney Tower was built, requires a specialised craneage solution to dismantle it. Now fully erected, the top of the tower crane stands over 200 metres above ground level. In early 2020, Mirvac assembled a team of leading Australian and international engineers and contractors including Marr, Robert Bird Group and critical infrastructure experts Kordia, to come up with a solution for designing and managing the process for dismantling the tower, which faced several challenges due to its size and location. “At 233-metres, this tower is equal in height to a 77-storey building which posed a number of challenges. So, Mirvac approached us to see if we could come up with a solution, using our tower cranes and bespoke equipment, as an alternative to more traditional methods of deconstruction.,” said Marr’s Managing Director, Simon Marr. “As the decommissioned tower was not structurally sound enough to attach lateral supports, the challenge from a craneage point-of-view was to find a way to get the crane hook height above 233 metres without the need to build expensive and complicated temporary structures to support the crane. “We spent 12 months working with multiple stakeholders including our lead […]
