This Information Paper outlines the principal drivers for reusing foundations and discusses why developers, building owners and construction professionals should consider it. Changes to legislation, growth in technical understanding, recognition of the needs of the environment and sustainability are all working together to drive us to reuse foundations, in response to the increasing pressure on available land for re-development in inner cities, and to find more cost-effective and sustainable methods of construction. 6 pages. The text is a short extract from 'Reuse of foundations for urban sites: a best practice handbook', published by IHS BRE Press (EP75).
