Historic Construction And Conservation

Conservation in the built environment raises fundamental questions which have been debated for centuries - what is worth preserving, how is it possible, why is it important? This book takes a modern approach to the meaning of a heritage structure and its conservation. The historical evolution of conservation is briefly addressed, considering prominent individuals and cases; along with the history of construction, focusing on materials and related structural elements, with insight on the sizing rules adopted by masons. This explains structural decisions made during the construction process and allows comparison of scientific theories from the 18th century to modern understanding of limit analysis. Damage and collapse mechanisms for masonry construction, as the most widespread structural form for historical buildings, is described. Excess permanent loading and settlement is differentiated from environmental and anthropogenic actions such as earthquake or incorrect intervention. The team of authors brings together unique expertise, with high level research and leading practice with archetypical cases from around the world. The book addresses the history of conservation by exploring materials and structures and the history of construction and damage, so it is of value to students and professionals in civil engineering and architecture, as well as archaeologists and art historians.

This book is the second in a series of volumes that combine conservation philosophy in the built environment with knowledge of traditional materials, and structural and constructional conservation techniques and technology: Understanding Historic Building Conservation Structures & Construction in Historic Building Conservation Materials & Skills for Historic Building Conservation The series aims to introduce each aspect of conservation and to provide concise, basic and up-to-date knowledge for architects, surveyors and engineers as well as for commissioning client bodies, managers and advisors. In each book, Michael Forsyth draws together chapters by leading architects, structural engineers and related professionals to reflect the interdisciplinary nature of conservation work. The books are structured to be of direct practical application, taking the reader through the process of historic building conservation and emphasising throughout the integrative teamwork involved. This present volume – Structures & Construction in Historic Building Conservation - traces the history of structures in various materials and contains guidance on the survey, assessment and diagnosis of structures and the integration of building code requirements within the historic fabric. It discusses conservation engineering philosophy, exposes the conflict between building codes and conservation legislation, and offers solutions. Leading-edge, on-site metric survey techniques are described and a range of structural advice is given, including methods of repair in relation to philosophical principles. Causes of induced movement in historic buildings are explained, together with basic soil mechanics and the assessment and diagnosis of structural failure. Chapters also cover the conservation of different types of construction: masonry, iron and steel, and concrete and reinforced concrete. Fourteen chapters written by the experts present today's key issues in structures and construction for historic building conservation: Bill Blake, Michael Bussell, David Cook, Dina F. D'Ayala, Steve Emery, Michael Forsyth, Ian Hume, Peter Norris

The present volume - Materials & Skills for Historic Building Conservation – describes the characteristics and process of decay of traditional materials which inform the selection of appropriate repair techniques. It provides essential information on the properties of the principal traditional external building materials. Their availability, sourcing and environmental impact is covered, as well as the causes of erosion and decay, and the skills required for their application on conservation projects. It covers the main most commonly used materials and conservation techniques including stone, brickwork, lime products, concrete, iron and steel, timber, wattle and daub, and glass, Thirteen chapters written by the experts present today's key issues in materials and skills for historic building conservation: Gus Astley, Patrick Baty, Charley Brentnall, Michael Bussell, Michael Forsyth, Tony Graham, Chris Harris, David McLaughlin, Brian Ridout, Mike Stock, Geoff Wallis, Ian Williams, Rory Young

Over the concluding decades of the twentieth century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, gas stations and diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior’s National Park Service and first published in 1995. Now, this invaluable guide is being reissued—with a new preface by the book’s original editor. With more than 250 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminum, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume. The book is intended for a wide range of conservation professionals including architects, engineers, conservators, and material scientists engaged in the conservation of modern buildings, as well as scholars in related disciplines.

This practical guide to the assessment and repair of historic buildings is invaluable for structural engineers, architects, surveyors and builders working in all aspects of building conservation. Taking a practical step-by-step approach, the authors discuss the appraisal of buildings and the differences in structural behaviour between new and existing structures. Each stage in the appraisal is explained, using examples from the authors' own work. Each major construction material is assessed in detail, with separate sections on masonry, concrete, timber and the particularly complex issues of iron and steel framed buildings. Techniques for testing the ability of a building to continue its existing use or to be converted to a new use are explained.

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 of understanding, interpreting and managing the architectural heritage to safely deliver it to posterity, enhancing private or public utility vis a vis minimum loss of fabric and significance. These two objectives are sometimes conflicting. With increasing global interest in conservation engineering it is essential to open the debate on more inclusive definitions of significance and on more articulated concepts of safety by use of acceptable and reliable technologies, integrating further the activity of all the professions involved in conservation.
