The 2005 version of the JCT Intermediate Building Contract has introduced a very different looking contract format and a number of changes to contract conditions. A completely new Intermediate Building Contract with Contractor's Design has also been issued. This well established guide, which has been thoroughly updated, looks at the changes and key aspects of both forms, and takes account of new case law since the last edition of the book published in 1999. It also discusses the new subcontract agreements.
