Client Overview
L&Q is leading the regeneration project at Greenwich Peninsula, Plot 18, focusing on providing affordable, high-quality housing. A key aspect of the project is the installation of a unitised façade system, which requires precise coordination with crane operations to maintain efficiency.
Challenge: Enabling Efficient & Continuous Façade Installation
The project faced a unique challenge with the installation of the unitized façade system on Blocks A and E. To maintain efficiency and ensure smooth progress, the crane needed to rise in tandem with the building’s construction. The sequential nature of the façade installation meant that any delay at one level would affect all subsequent levels. To successfully install the façade panels, the crane’s height had to be increased by 25m, and the existing tie structure needed to be modified without disrupting the façade installation process.
Solution: Tie and Climb Operation by Radius Group
Radius was chosen for their ability to meet the project’s complex requirements. They executed the crane’s “tie and climb” operation, increasing the crane’s height by 25m through to complete full height construction of the tower block.
Additionally, Radius facilitated the design, fabrication, and installation of the complete floor bracket system and modular ties required for the project. To optimise the façade installation process and overcome the challenge, L&Q approached Radius mid-project and requested a feasibility / engineering study to investigate a solution to overcome the challenge.
The best overall solution from a commercial and program perspective was a specialist modular swing-away 4-beam tie strategy. This would allow for the outer ties to be disconnected / spliced and swung away to allow for future installation of the panels; resulting in seamless continuation of façade installation across subsequent floors.
Results: Optimised Construction Efficiency
The innovative four-leg strategy provided the only engineering solution that enabled L&Q to maximize the value of their unitized façade system. By partnering with Radius Group, L&Q was able to:
- Safely execute the crane height increase while maintaining project momentum.
- Streamline the façade installation process, ensuring that delays were avoided.
- Safely remove and reinstate ties during the panel installation process.
The successful completion of the tie and climb operation ensured that the project remained on track, allowing the team to move forward with the remaining construction phases. With the tie and climb complete, Radius is now coordinating with the client on crane removal.
Testimonial from Nathan Richards, L&Q Senior Project Manager, Greenwich Peninsula
“After months of collaboration between L&Q, Radius, Potain, Focchi, and Walsh, the successful planning and execution of the Tie and Climb strategy at Greenwich is a real testament to Radius’ expertise and their commitment to fulfilling the brief they were given.
When we encountered issues, Radius was proactive in seeking solutions, bringing a wealth of lifting and engineering knowledge to the table. This drive for viable solutions has allowed L&Q to maintain the critical path through our tallest tower at Greenwich and to offer program certainty on much-needed affordable homes on the Peninsula.
In a sector where technology and methodology are constantly evolving, Teddy, Gurjit, and Jamie are always willing to listen to new ideas and offer advice and solutions when appropriate, keeping value for their customers in mind.”
