Much of the metalwork was of contemporary design and considered at that time to be ‘fireproof’. This paper discusses the origin of metalwork, its incorporation into the historic fabric, its performance under fire load, its collateral fabric damage, and its retention or replacement. Forensic techniques are described which gave the engineer an insight into the fire conditions experienced by the metalwork and how an assessment was made of components which were to be retained. New steelwork of current design is now incorporated in a way which draws upon an understanding of how metalwork behaves in historic masonry surroundings.
