MASTERPIECE 2025: Civil Hydraulic

John Gorton Building Hydraulic and Intersection Works

The John Gorton Building project involved significant civil and stormwater construction work, including the demolition of an existing open-air car park and the construction of a new multi-storey car park. Complex Co. delivered the civil works, removing old stormwater components and installing a new large-diameter stormwater network. This upgrade was essential for transforming the Kings Avenue/Blackall Street intersection into a four-way signalised intersection, ultimately providing over 1,000 new car parking spaces. Complex Co. successfully navigated the challenges of the project, organising the work in such a way that there was only a two-day closure of Kings Avenue throughout the entire construction period. Judges were impressed with the project management and level of technical complexity in the project, awarding high scores across the board and calling it ‘an amazing, well-coordinated project.’
