The scope of works included:
Covering 400 hectares and involving a 75 million tonne waste rock dump, a 25 million tonne tailings dump and open pits with significant volumes of water, the scope and scale of our integrated works programme was complex. In order to satisfy an urgent timeframe we undertook concurrent structural demolition works alongside stringent materials handling and load out requirements to complete the deconstruction 8 weeks ahead of schedule and within budget.
All demolition works were carried out in accordance with Work Health & Safety Act and Environmental Management Plans in consultation with WorkCover NSW and the Environmental Protection Authority (EPA). This included regular independent audits, carried out to verify our compliance with safety and environmental requirements.
There were no safety incidents and a comprehensive air monitoring program undertaken by an Independent Licensed Asbestos Assessor for the duration of site works confirmed there no off- site impacts arose from our work.
The derelict buildings and infrastructure were demolished and buried on site within an EPA approved engineered containment cell. Revisions of the size of the cell were completed as a result of greater than forecast volumes of contaminated waste. We are also able to identify some structural steel from within the Mill Building for recycling, following a decontamination process which was verified by the Independent Licensed Asbestos Assessor.
