The construction enterprise is being transformed by visual modelling. Once principally used by researchers and in niche industries, tools such as 3D/4D CAD and virtual reality are now in widespread use in construction. This book is both a survey of the changes being made in practice and a detailed guide to future directions for research and development bringing together the work of leading practitioners and academics. A particular strength of the book is its many detailed case studies and examples, making it an excellent resource for practitioners, researchers, and students seeking to understand the details of how new tools and methods are applied in a business context. The 11 chapters address following topics: - Uses of 3D/4D CAD and its costs and benefits, - Applications of visual modelling at the work face, - Applications of visual modelling in the designer office, - Technical integration of visual modelling tools such as 3D/4D CAD and virtual reality.
