Bulimba Sewer Trunk Main, Brisbane

Abergeldie, in joint venture with Obayashi delivered the Bulimba Sewer Trunk Main project for Urban Utilities. This significant upgrade to the network improved sewerage infrastructure for a growing number of residents and businesses across Brisbane. The project, which included gravity trunk sewer installation using trenchless technology, was a finalist in the CCF QLD Earth Awards.

The contract was varied at the client’s request to include the pipe-jacked construction of a new Fortrose Street rising main and Jindalee water main replacement, which went on to win the IPEAQ Innovation in Water Award in 2019.

Mandalong Vent Shaft

Abergeldie was engaged to design and construct one vertical, hydrostatically lined, blind bored ventilation shaft to serve underground mine works at Centennial Coal’s Mandalong operations near Lake Macquarie on the Central Cost of NSW. Works for the 5.5m diameter, 360, deep shaft were carried out on an active mine site, requiring strict obervance of mine safety and environmental protection procedures, and close cooperation with the mines operations management team.

Shaft sinking was carried out using Abergeldie’s owned, operated and maintained blind boring rigs, which are the world’s largest of their type.
