Many building contract claims are ill-founded, often because the basic principles are misunderstood. This highly regarded book examines the legal basis of claims for additional payment, and what can and cannot be claimed under the main forms of contract. It includes chapters dealing with direct loss and expense, liquidated damages, extension of time, concurrency, acceleration, time at large, common law and contractual claims, global claims, heads of claim and their substantiation. The new fourth edition has been substantially restructured and updated. Nearly 100 additional cases have been added as well as four new contracts : the JCT Construction Management and Major Project contracts, the JCT Standard Form of Domestic Subcontract, and the Engineering and Construction Contract (the NEC Form). The book continues to use the JCT Standard Form (JCT 98) as the basis of the text, with important differences highlighted in the other forms. Seventeen forms are dealt with and they have all been updated since the last edition of this book.This new edition is essential reading for architects, contract administrators, project managers and quantity surveyors. It will also be invaluable to contractors, contracts consultants and construction lawyers.
