Guide to DB05, the new edition of Sarah Lupton's very successful Guide to WCD98, is a practical guide to the operation and administration of the JCT Design and Build Contract (DB05). It points out the important changes to the contract by reflecting on up-to-date cases which serve as valuable lessons to the unwary.
The contract's provisions, procedures, and supplementary conditions are organized and defined by subject and supported by useful indexes, while a clause comparison table allows for a quick and easy way to understand how DB05 relates to the old contract, WCD98.
The guide provides the hard-pressed practitioner with a comprehensive, concise reference guide to contractual issues during the course of a job under the contract.
