The Sirius Building in Sydney, an iconic Brutalist landmark overlooking Circular Quay, has been carefully revitalised to preserve its architectural significance while integrating high-performance contemporary façade systems. Rickard Engineering was engaged as façade engineer to deliver the design and certification of the external cladding, highlighted by the innovative use of ultra-thin 0.5 mm copper cladding, requiring specialised engineering to ensure durability, constructability, and long-term performance while maintaining the building’s original design intent.
Our scope included:
- Wall and awning cladding assemblies
- Roof parapets and interface detailing
- Balcony pod wall and ceiling claddings
- Balconies perforated stainless steel tiles
Through precise detailing and careful coordination, we enabled the successful application of this refined and lightweight copper solution, balancing material efficiency, aesthetic quality, and façade performance on one of Sydney’s most iconic heritage projects.
