Powerhouse Parramatta will require an estimated 12,000 tonnes of steel during construction. This is mainly attributed to the use of an exoskeleton, an awe-inspiring architectural feature that provides structural integrity while giving the building a distinctive, clearly articulated appearance.
An exoskeleton is a structural design system that uses an external framework to support the building, instead of relying on internal columns and beams. The system supports the building's weight and load, similar to the way the human skeleton supports the body.
The exoskeleton is a unique architectural feature that sets this building apart, providing structural integrity whilst giving the museum a distinctive, clearly articulated appearance that blends seamlessly into the natural environment. It also allows a greater amount of natural light to penetrate the building, creating an inviting space that changes dynamically throughout the day.
The Powerhouse Parramatta exoskeleton is designed with 3 types of steel lattice that enable the interiors to be column-free, large volume spaces which will vary in size, scale, and offerings.
This building will require an estimated 12,000 tonnes of steel during construction, triple the amount of steel used to build the new Allianz Stadium at 4,000 tonnes.
The exoskeleton is made up of 1,237 individual pieces of steel, comprising W, X, J and A shaped pieces ranging from 4m in height to over 20m that form together. During construction, exoskeleton sections are first assembled on the ground on site, then lifted into place by the tower cranes.
