Over the last two hundred years, concrete has been used to produce a remarkably rich and diverse legacy of buildings and structures that are increasingly recognized for their cultural significance. With this growing recognition comes the need for protection and conservation. However, concrete conservation is still a relatively new field with limited availability of guiding resources. Conservation Principles for Concrete of Cultural Significance intends to fill that gap, recognizing that much knowledge can be drawn from best practices in general repair of concrete; however, historic structures demand additional care to ensure that any work performed retains their cultural significance.Conservation Principles for Concrete of Cultural Significance provides a framework for architects, engineers, conservators, contractors, and stewards to make sound, informed decisions for conserving culturally significant concrete buildings and structures by referencing both concrete repair standards and international conservation principles. The principles outlined in this document are meant to provide a logical approach to concrete conservation, leading practitioners through the typical conservation methodology, from investigation to the development of conservation strategies to implementation and maintenance. Its underlying premise is that concrete, in all its guises, may be of cultural significance and deserves a careful, knowledge-based approach to its care in order to sustain it for future generations. It has been extensively reviewed by experts in concrete conservation, and their contributions were valuable in shaping the final document and reaffirming its need.

The first title in a new series aimed at sharing best practices in the conservation of modern heritage. This timely volume brings together fourteen case studies that address the challenges of conserving the twentieth century’s most ubiquitous building material—concrete. Following a meeting of international heritage conservation professionals in 2013, the need for recent, thorough, and well-vetted case studies on conserving twentieth-century heritage became clear. Concrete: Case Studies in Conservation Practice answers that need and kicks off a new series, Conserving Modern Heritage, aimed at sharing best practices. The projects selected represent a range of building typologies, building uses, and project sizes, from the high-rise housing blocks of Le Corbusier’s Unité d’Habitation and public buildings such as the London’s National Theatre to small monuments such as the structures at Dudley Zoological Gardens and a sculpture by Donald Judd. The projects also represent a range of environmental and economic contexts. Some projects benefit from high levels of heritage protection and access to funding, while others have had to negotiate conservation with stringent cost limitations. All follow a rigorous conservation approach, beginning with a process of investigation and diagnosis to identify causes and target repairs and balancing these with conservation requirements to preserve significance. Written by architects, engineers, conservators, scholars, and other professionals in the field, these highly detailed and well-illustrated studies demonstrate sound practice, rigorous methodology, and technological innovation and represent the vibrancy of the field as it stands today. This book has something to offer anyone interested in the conservation of modern heritage.

This book gathers the latest advances, innovations and applications in the field of historic mortars and masonry structures conservation and restoration, as presented by international researchers and professionals at the 6th Historic Mortars Conference (HMC), held in Ljubljana, Slovenia, on September 21–23, 2022. It covers topics such as characterization of historic mortars and masonry structures—sampling and test methods; historic production, processing and application of mortars, renders and grouts; assessment of historic renders and plasters; conservation and preventing conservation case studies; repair mortars and grouts—requirements and design, compatibility issues, durability and effectiveness and adequacy of testing procedures. Special attention is given to historic mortars where one of the binders or the only binder is Portland cement and to the structures in which these materials are used. The contributions, which were selected through a rigorous international peer-review process, share new knowledge and exciting ideas that will help protect heritage buildings more efficiently and foster new multidisciplinary collaborations in this area.

Bringing together leading conservation scholars and professionals from around the world, this volume offers a timely look at values-based approaches to heritage management. Over the last fifty years, conservation professionals have confronted increasingly complex political, economic, and cultural dynamics. This volume, with contributions by leading international practitioners and scholars, reviews how values-based methods have come to influence conservation, takes stock of emerging approaches to values in heritage practice and policy, identifies common challenges and related spheres of knowledge, and proposes specific areas in which the development of new approaches and future research may help advance the field.

In this important book, the authors unpack the theoretical and practical issues around the development of heritage sites, critically dissecting key conservation benchmarks such as the ICOMOS guidelines, BS 7913 and the RIBA Conservation Plan of Work to reveal the mechanics of heritage guidance, its advantages and conceptual limitations. Underpinned by an active understanding of the conservation philosophy of William Morris, the book presents five case studies from the UK and North and South America that speak about different facets of heritage value, such as urban identity, commodification, authenticity, materiality and heritage as an intellectual and ethical framework. Heritage is never neutral; its definition is privileged yet its influence is political. Art, landscape and archaeology all offer examples of how the operational ideas of adjacent disciplines can influence an integrated idea of heritage conservation, and how this is communicated in order to determine significance and share in its custodianship. This book provides insights into how to identify and challenge these limitations, expanding inclusion by describing tactics for changing how people can relate to and build on the past. Clearly written for all levels of readership within the conservation professions and community custodians of heritage buildings and places, the book provides strategies and tactics for understanding the heritage significance of materials, their fabrication, detail and use. The narratives that historic fabric contains can help shape the meaningful involvement of local people, providing a roadmap for those navigating the double-bind of using the past to underpin the future.

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

The conservation of our Modern architectural heritage is a subject of vehement debate. When do buildings become old or significant enough to warrant special heritage status and protection? Should Modern listed buildings be treated differently from those of earlier periods? And what does all this mean for building users and owners, who might be better served if their buildings were less authentic, but more comfortable and usable? Presenting a clear line of sight through these complex questions, this book explores the conservation, regeneration and adaptive re-use of Modern architecture. It provides a general grounding in the field, its recent history and current development, including chapters on authenticity, charters, listing and protection. Case studies drawing on the author’s extensive practical experience offer valuable lessons learnt in the conservation of Modern heritage buildings. Looking beyond the specialist field of ‘elite’ heritage, Revaluing Modern Architecture also considers the changing culture of conservation for ‘sub-iconic’ buildings in relation to de-carbonisation and the climate emergency. It suggests how revaluing the vast legacy of modern architecture can help to promote a more sustainable future. Features leading conservation projects, such as the celebrated Penguin Pool at London Zoo, Finsbury Health Centre by Lubetkin & Tecton and Wells Coates’ Isokon (Lawn Road) Flats, as well as previously unpublished projects. Analyses key Modern conservation controversies of recent years Illustrated with over 160 photos and drawings. An essential primer for architectural students and practitioners, academics, those employed in conservation and planning, property owners, developers, surveyors and building managers.
