Pentagon Consulting has been engaged to manage risk and safety associated with high-risk demolition and chemical remediation projects since 1997. We have successfully completed some of Australias most risk inherent projects over this period.

Cockatoo Island Dockyard

Pentagon was engaged as the Project Manager for the Demolition & Chemical Remediation of Cockatoo Island Dockyard. This project involved remediation of Sodium Cyanide, Friable Asbestos, Hydrocarbons, Mercury and other Heavy Metal contamination on Cockatoo Island Dockyard. Additionally, we were responsible for the demolition of a large number of chemically contaminated industrial buildings and a series of 400 Tonne Naval Wharf Cranes from structurally compromised timber wharfs.

Garden Island Dockyard

We managed the demolition and chemical remediation of a large number of Heavy Industrial Naval structures within the RANs Fleet Base East at Garden Island in Sydney. This included the remediation of friable asbestos and heavy metal contamination.

Zetland Concrete Friable Asbestos

Pentagon was contracted to manage the beneficial use of 80 000 cubic metres of friable asbestos-contaminated waste (Zetland Concrete), and 40 000 metres of high Silicate content Dimension Stone which was illegally dumped at Boral Prospect Quarry in Sydney. This project involved utilising the Zetland Concrete and Dimension Stone in the construction of an artificial aquifer in an extremely caustic (pH >12) environment.

Sewerage Treatment Plants

Pentagon has managed the demolition of a large number of Sewerage and Waste Water Treatment Plants across Australia. This included managing remedial processes and safety risks associated with the biohazard, friable asbestos and chemical remediation of the Sewerage Treatment Plants.

Chifley Tower

We managed the safety aspects associated with a large-scale strip out of Chifley Tower during a major refurbishment in 2005.
