The job of the estimator is explained in detail at every key stage, from early cost studies, through the preparation of the estimate, to the creation of budgets for successful tenders. Each step is illustrated with examples and notes, and appropriate technical documentation. Over recent years there have been significant developments in construction management, notably new procurement methods, greater emphasis on innovation and partnering, a greater reliance on cost planning as a methodology, and new developments in both industry and governmental reports and guidance. This new and updated edition of a well-established textbook addresses each of these developments in turn, placing them firmly in the context of a thorough and easy to understand introduction to the roles of the estimator in preparing and winning tenders. It adopts a practical approach to estimating from the contractor's point of view. It is fully up-to-date with new procurement methods and includes many examples of estimators' notes and documents.
