The New Air Combat Capability (NACC) Facilities Project is a $1.6 billion investment into RAAF base facilities in preparation for the Joint Strike Fighters introduction in 2019. Prior to any facilities and infrastructure works taking place the work sites had to be remediated to remove the threat of unexploded ordnance (UXO).
RAAF Williamtown is an operational base and OPEC managed multiple work areas simultaneously to ensure that the relevant stakeholders were not inconvenienced by its work processes.
The project involved over 120 hectares of digital survey utilising the innovative Ultra TEM technology. This high spatial resolution three-component Electromagnetic Induction (EMI) detection technology enabled OPEC to narrow down the potential UXO anomalies to a specific target size. This reduced remediation time and cost dramatically, often by over 40% compared to outdated technologies based on magnetometers or EM61 metal detectors.
OPEC has investigated over 10,000 anomalies and removed over 9,800 items of explosive ordnance (EO) from the site, including a complete buried WWI artillery gun.
