Permacast expertly delivered the Wheatstone Gas Project, managing a highly complex and ambitious scope that required precision engineering, rigorous quality control, and innovative precast solutions. The project showcased our ability to produce a diverse range of specialised precast components, including culvert trench units, perlite-lined trench units, perlite wall panels, fire-rated wall panels, and robust firewall columns. Our approach demonstrated exceptional attention to detail, adaptability, and reliability, ensuring the highest standards were met across all aspects of manufacturing and delivery.

• 975 Culvert Trench Units (average weight 20 tonnes)
• 113 Perlite Lined Trench Units
• 760 Perlite Wall Panels (average weight 170 kilograms)
• 703 Fire Wall Panels (average weight 4 tonnes)
• 254 Firewall Columns (average weight 14 tonnes)

• Each precast culvert unit was uniquely designed to precisely match the finished floor level (FFL) gradients and falls, ensuring perfect site integration.
• Advanced 3D modelling was employed to guarantee constructability and manufacturing accuracy for every unit.
• Originally intended as an in-situ solution, the project was adapted for precast components without compromising design integrity.
• Products were manufactured to exacting standards, with stringent quality controls and comprehensive reporting throughout the process.
• Detailed joint designs ensured watertight connections, eliminating leaks at in-situ interfaces.
• Capacity to store up to 700 culverts enabled efficient just-in-time delivery, optimizing site logistics.
• Utilised high-specification S50 low-heat concrete to achieve overnight strengths of 20 megapascals.
• Maintained a consistent production rate with daily casting of six culverts, meeting tight project timelines.
