As the Building Regulations and Approved Documents have become more and more complex, they have become increasingly unfriendly for a professional user. Compliance is only possible by understanding a wide range of supporting documentation. Alternative approaches are implied, but not described or analysed. This book examines Approved Document C on Site Preparation and takes the user through all the key stages of preparation, compliance, inspection and enforcement. It offers practical advice on using not just the traditional routes to compliance but also on the alternative approaches suggested but not explained in the Approved Documents. The advantages and disadvantages of each form of compliance are analysed in depth. Everything you need to know to prepare a site's fixtures against contamination and moisture is discussed, including floors, walls, window frames, door tresholds, and roofs. This is an indispensable text for professional designers, architects, structural and other specialist engineers, building control officers and students in construction, building and architecture.
