Clough, in a joint venture with Agility Team Build and AJ Lucas Contractors, completed the design, engineering, construction, and commissioning of Stage 4 and Stage 5 of the Roma to Brisbane Gas Pipeline Looping project.

The Stage 4 project involved the delivery of a pipeline consisting of four loops, which were extended of existing lines, with a total length of 51km. The four new pipelines were installed over different terrains ranging from Ipswich’s inner city to the Toowoomba Range to open forest. 

The Stage 5 project involved of the delivery of a 160-kilometre x 400-millimetre diameter steel pipeline for the looping, a 11-kilometre x 400-millimetre diameter lateral pipeline connecting into the Swanbank Power Station and a 10-kilometre x 250-millimetre diameter pipeline extension to the APT’s Peat Lateral Pipeline associated with the Scotia coal seam methane gas field. Stage 5 also involved mainline valve and scraper stations work.
