Challenge and proposed solution

Precast building cores are a widely adopted solution for multi-storey buildings, particularly those up to 20 storeys in Australia.

Traditionally, these systems rely on casting 4 separate rectangular panels, transporting them to the site, and stitching them together on-site. LTE Structures has identified and developed a system to unlock new opportunities and set a new standard for efficiency and performance within precast core construction by manufacturing entire 3D cubes. While the benefits of this method have been identified in the past, historically the approach was long considered cost-prohibitive and unfeasible.

LTE Structures has partnered with Optimised Engineering Solutions and researchers from Swinburne University to validate their revolutionary new post-tensioned precast cube system for building cores. The system will significantly increase construction speeds while reducing construction timeframes. On site, it would reduce overheads such as the amount of workers, carparks, sheds, tower cranes, truck deliveries and waste. The system’s use of high-tensile post-tensioning cables instead of traditional reinforcement would also reduce the amount of steel needed. These, and many other indirect benefits, all contribute to significant efficiencies and cost-reductions in the construction of multi-storey buildings. Meanwhile, researchers will produce design guidelines and recommendations for code updates to the Australian Standards to encourage wide industry adoption of the system.
