Scaffolding around an “onion”
The scaffolding for the heritage-listed Lands Department Building in Sydney, Australia, with its splendid facade and copper dome – also known as the “onion” – meant a few special challenges for the local scaffolding erectors: firstly, several components had to be bridged. And secondly, the overall weight of some 5,000 square metres of work scaffolding was an important factor, as the part of the area around the building has tunnels underneath it. The solution: Allround Scaffolding with Lightweight technology. With its lightweight yet strong components, it not only ensured a material-saving structure that was also optimally adapted to the building’s geometry, but also offered matching extension parts to meet all on-site requirements. A solution with a system.

• Layher’s applications engineers devised the digital 3D scaffolding model, jointly with the client, with the aid of LayPLAN CAD. The above solution was checked, discussed and adapted based on the realistic scaffolding model.
• Instruction on site by Layher’s applications engineers
• Low overall weight, thanks to material-saving design and to the use of components with lightweight technology
• Wide-span bridging using the Allround FW System. Due to the limited storage space in the city centre, the FW System structures were pre-assembled at the warehouse in 10 metre-sized sections, then transported to the site, connected up and finally lifted into place by crane
• Bracing for heavy loads inside the building using the high-strength aluminium FlexBeam
• Allround platform stairtowers for safer and faster site access
