This volume covers the second great period of developments in iron construction from 1850, following its establishment as a structural material described in volume 9 of this series. Using the Crystal Palace of 1851 as a starting-point, the papers trace the history of iron-frame construction in Britain, France and America, and show its importance in fireproof construction, and in lattice truss and arch bridge design. A final group of papers illustrates the emergence of steel in framed buildings in both Britain and America. The selection brings out the important and daring contribution of individual engineers in their use of this material.

This book deals with the period when iron became the dominant ’high-technology’ material, increasingly taking over from timber and masonry. It was necessary for the engines and machines of the new industries, but equally vital for the vast civil engineering works which supported this industrialisation. It was these works - mills, warehouses, dockyards, and above all bridges - which so impressed the public in the early 19th century. The papers selected here trace the evolving structural uses of cast and wrought iron in frames and roofs for buildings, and look in particular at the development of bridge design and construction, in America, France, and Russia, as well as in Britain. They cover the processes of design and testing, and at the same time throw much light on the attitudes and careers of the engineers themselves.

The successful preservation of an historic building, complex or city depends on the continued use and daily care that come with it. The possibility of continued use depends on the adaptation of the building to modern standards and practice of living, requiring changes in constructional or structural features. Conservation engineering is the process
