The Red Book has been the subject of a detailed review. This new edition takes into account users' experiences and the latest thinking in project execution. The impact of recent legislation is also covered. The guidance section is now separated into two parts with Section 1 providing specific guidance on completing the Contract Agreement, its annex, the specification and schedules which themselves have been increased in number, and Section 2 the guidance notes, discussing general issues to aid understanding, highlighting areas where special conditions may need to be written for the users' requirements.
