IStructE - James Sutherland history lecture 2025

The annual James Sutherland history lecture showcases outstanding research in the history of structural engineering. The 2025 lecture will be delivered by Professor Dr. Stefan M. Holzer and will explore the crucial role of temporary works in historical construction sites.

Temporary works, such as scaffolding, lifting gear, and centring for arches and vaults—played an essential role in the execution of historic structures. However, as they rarely left behind clear traces, reconstructing their use requires a combination of building analysis, archival research, pictorial evidence, and early technical literature.

This lecture will highlight how temporary works not only provided access to worksites but also facilitated material transport and influenced structural designs. Understanding these historical construction procedures offers valuable insights for engineers involved in rehabilitation works.
