Caltex Hamilton Service Station Demoltion

DURATION3 months
CLIENTEconomic Development Queensland (Department of Infrastructure, Local Government and Planning)

The project involved the complete site demolition and remediation of a former Caltex Service Station in Hamilton, Queensland. The demolition works includes asbestos removal from the amenities building and asbestos pipework. The demolition also included removal of all hardstand concrete from across the site.

Remediation works included the excavation and removal of five underground storage tanks. Prior to removal the tanks had a small hole cold cut to allow a tank cleaning head to be used to clean, flush and remove any residual liquids from the tanks and make the tanks gas free.

The tanks and associated pipework were broken down on site and sent to metal recyclers. Also, all the concrete slabs, footings and suitable building materials like bricks and tiles were sent to recyclers.

As part of the remediation works, up to 2,000 m3 of contaminated soils were excavated and transported to licensed landfill for disposal. During excavation and stockpiling works, the site used Anotec fog sprayers wilth odour control suppressant additives due to site location adjacent to local park and residences. Following remediation works, the site was backfilled and compacted up to grade with imported VENM. Liberty Industrial also installed three new groundwater monitoring wells which were damaged during the tank removal works.
