Architects, engineers and surveyors work with large numbers of contracts and other documents. These may contain standard or typical clauses which are encountered frequently but that may have implications far beyond the obvious, especially with regard to terms of engagement and collateral warranties. This essential book provides practical guidance on the legal and commercial risks which these clauses pose and gives advice on the acceptability of particular clauses by reference to case law and first-hand experience. Innovative and unique, this key book, essential for practitioners, illuminates the legal and commercial considerations, not only of the parties they represent, but of all members of the project team. Quantity surveyor Mark Hackett and lawyer Mark Klimt have wide ranging and current experience of terms of engagement and collateral warranties used in a broad spectrum of projects. By virtue of their respective disciplines, this significant volume addresses matters from both the legal and commercial perspectives; readers will find priceless practical advice on navigating safely through different contract forms, and consultants are shown how to take guidance on sensible and workable contractual arrangements which, most importantly, will have the support of the insurance market.
