We are an Australian owned and operated company with access to the most advanced technology in the world.
Founded in Victoria in 1961, the Company commenced trading as BBR Australia Pty Ltd. The first project the Company undertook was the supply and installation of rock anchors for the Snowy Mountains Scheme. Listed on the Australian Stock Exchange as Structural Systems Limited in 1987 and now fifty years on from the first project, the organisation has grown from a small privately owned specialist post-tensioning company to a diverse international contractor.
The Company's head office is located in South Melbourne, Victoria, and manages its operations within Australia from offices in Melbourne, Sydney, Brisbane, Perth, Adelaide, Kalgoorlie and Townsville. Internationally the Company has offices in Dubai, Qatar, Bahrain and South Africa.
