Munmorah Power Station Demolition and Removal

Munmorah Power Station Demolition and Removal

Colongra, NSW
Generator Property Management Pty Ltd
 28 months
Completed 2018


Generator Property Management commissioned Liberty Industrial to remove a 1,400 megawatt coal fired power station including four 350 megawatt steam driven turbo- alternators, two 155m high chimney stacks, four boiler houses, coal handling plant and conveyors and 2.3km of ash lines.


  • Removing 890 tonnes of bonded and friable asbestos throughout the site prior to demolition while working at heights of up to 60 metres in an area prone to high winds.
  • Adhering to strict Environmental Protection Licence (EPL) – the site was located between Lake Munmorah and Lake Budgewoi, which are connected by two cooling water canals that run through the site.

Robust Solutions/Exceptional Outcomes

Robust solutions

  • Careful planning and extensive consultation with SafeWork NSW and a number of government regulatory authorities to ensure full compliance.
  • Intensive investigations to identify areas of asbestos which were not previously known to the client.
  • Detailed engineering studies and 3D modelling simulation.
  • Mobilisation of 20 asbestos specialists.
  • Deployment of full-time hygienist with on-site lab.
  • Construction of a range of negative air encapsulations throughout the 60m height of the boiler structures.
  • Construction of a highly engineered and detailed access scaffolding and enclosure to access the penthouse at the top of the boiler houses, which included the use of a 300t crane to lift up the required plant and equipment.
  • Construction of a 30m x 20m removable dome shelter for use as a fully functional mechanical workshop managed by Liberty Industrial’s in house mechanics.
  • Provision of state-of-the-art equipment including Liberty Industrial’s own 230t Liebherr 994 complete with the world’s largest shear attachment − the Genesis GXT 2555R.
  • Meticulous organisation and execution of controlled explosive techniques to topple the majestic twin stacks exactly as planned.


Exceptional outcomes

  • The entire project was masterfully executed, on time, on budget and without incident.
  • A staggering 98% of all waste was recycled − that’s 102,392t of material.
  • Liberty Industrial was awarded the Winner of the Industrial Demolition Award at the 2019 World Demolition Awards. The project was the largest power station demolition venture to be carried out in Australia to-date.
