DOWNER AWARDED DEFENCE REDEVELOPMENT CONTRACT IN SOUTH AUSTRALIA

Downer EDI Limited (Downer) today announced it had been selected to deliver the Planning Phase of the Australian Defence Force’s proposed Woomera Redevelopment Program in South Australia.

The Planning Phase will commence in September 2023. Under the contract, the Downer CPB joint venture will commence design development activities for the project (estimated value, $500 million - $750 million – subject to further Government review) that will form the basis of Defence’s submission for Government approval. Pending Government and Parliamentary approval and successful negotiations with the Downer CPB joint venture for the Delivery Phase, the project will deliver buildings, services and infrastructure works and meet the objectives of the Defence Strategic Review. Construction is planned to commence in early 2026 and is scheduled to be completed by early 2029.

Revenue will be split 50:50 between Downer and joint venture partners, CPB Contractors.

Under the contract, the joint venture will deliver buildings, services and infrastructure works to ensure compliance with Defence standards and meet the objectives of the Defence Strategic Review.

The Chief Executive Officer of Downer, Peter Tompkins, said the contract would continue Downer’s proud 80-plus-year relationship with the Department of Defence.

“Downer is Australia’s largest sovereign Defence partner, providing program management of Defence base redevelopments and upgrades, integrated facility and asset management across the Defence estate, and technical and professional services,” Mr Tompkins said.

“Downer is proud of the role we play in supporting the growth of Australia’s Defence capability and local industry participation.

“We look forward to working closely with the Department of Defence to develop these important facilities, which will support Defence capability for the next 30 years, while also providing an opportunity to support Indigenous and Small-to-Medium Enterprises across regional South Australia.”
