Status

Overview

The Barangaroo Delivery Authority commissioned Liberty Industrial for the deconstruction of the redundant 87m high Sydney Harbour Control Tower landmark consisting of a reinforced concrete column topped by a stainless steel and glass observation deck and operations room. The works formed part of Sydney’s multi-billion dollar Barangaroo Precinct Development Project.

Challenges

  • The base of the tower stood in the Cutaway, a huge underground cultural space under the Headland and rose through a void above the Headland Park.
  • The site was located in the middle of public space and challenges existed in minimising the impact on nearby residents, businesses and visitors to the Headland Park, where many heritage-listed buildings were present.
  • Given the high profile nature of this project and the significant degree of public interest, transparent and continuous stakeholder management was also an essential component of the project.

Robust Solutions/Exceptional Outcomes

Robust solutions

  • To enable continued use of the below-ground event space, Liberty developed an innovative and carefully considered deconstruction methodology, unlike any other, performed in Australia to date.
  • Development and implementation of a comprehensive environmental monitoring program to monitor dust, noise, vibration and meteorological data, ensuring compliance with strict regulatory approval conditions.
  • All asbestos and debris were removed inside the tower which was made possible with the erection of a circular mast climbing platform system in combination with Brokk remote- controlled demolition excavators and the assembly of a 20m-high ‘dust- proof wall’ which separated the works from the underground cultural space at the base.
  • Construction of a brand new ground slab to extend the underground event space, as well as the reinstatement of surroundings and construction of new landscape areas.

 

Exceptional outcomes

  • The project was completed to the client’s expectations and delivered on budget, on schedule and without issue or injury. We were able to achieve minimal disruption to the local community and upheld rapport with all project stakeholders.
  • Project resource recovery exceeded 98% of all materials with only 2% of the waste generated going to landfill.
  • Liberty Industrial was shortlisted as a Finalist in the ‘Urban Demolition’ category at the 2017 World Demolition Awards.
