This technical lecture uncovers HYLO, the co-winner of the 2022 Supreme Award for Structural Engineering Excellence. This groundbreaking retrofit project transformed a 16-storey 1960s building in a radical way—extending it vertically by 70%, adding 13 storeys, and effectively doubling the leasable area. Remarkably, the existing frame and foundations were entirely reused, with only essential strengthening undertaken.
The project team outlines how a detailed investigation and back analysis of the existing structure informed the design of the extension structure, allowing for targeted strengthening and the strategic reuse of foundations.
Watch the recording to find out more about the vital role of investigations and back analysis in maximizing the reuse of existing structures and the inherent benefits of retrofitting compared to demolition and rebuild.
