The Department of Mines, Industry Regulation and Safety (DMIRS) is working in partnership with the Department of Planning, Lands and Heritage (DPLH) to reduce the public safety risk of abandoned mine features at the Commonage and  Wanerenooka sites near Northampton, Western Australia. The DMIRS Abandoned Mines Program (AMP) requires geotechnical engineering services to support the assessment and rehabilitation of these features.

The Consultant will be required to conduct a geotechnical assessment, a rehabilitation option study, technical specification documents for earthworks and construction tenders, geotechnical supervision of rehabilitation works and a post works monitoring program.

The DPLH will be conducting contaminated sites investigations and heritage assessments across the same areas. This DMIRS geotechnical contract will need to inform those DPLH studies including identifying unsafe potential subsidence risk zones. The findings of the DPLH studies will also influence the abandoned mine feature rehabilitation options.

The contract delivery point for this project is the DMIRS offices located at Mineral House in the Perth Metropolitan area. Site travel to Northampton will be required.
