Liberty Industrial was engaged as the principal contractor for the decommissioning of the existing coal- fired Wallerawang Power Station, New South Wales. The scope included the demolition of two 59m boiler units, two 177m tall stacks, precipitators, coal handling plant conveyors, auxiliary bay, removal of equipment from within the turbine hall, smaller buildings, workshops, stacker reclaimer, road reclaim hopper, live storage hopper, complete HAZMAT removal and civil works.
- The team overcame these challenges by engaging specialised consultants such as a Heritage Structural Engineer, to inspect and analyse the current conditions of the heritage structures; Environmental Consultants to assess and provide predictions for air blast and vibration limits during blast events; and Applied Science International’s (ASI) innovative 3D modeling software to analyse and model scenarios for the falling of the two stacks and the two boiler units. The latter is a critical risk strategy to ensure that no damage occurs to these existing assets.
- Traffic Management was another challenge, with public road closures required for sections of the Castlereagh Highway and Main Street in Wallerawang during the three blast events. Our project team undertook continuous strategic planning with Greenspot, Transport for New South Wales and Lithgow City Council to provide a solution for the temporary road closures and prevented disruption to the access of these roads.
Liberty Industrial completed the project within a two-year timeframe and allowed the land to be returned to Greenspot and reused as an industrial park development.
