Cost models underlie all the techniques used in construction cost and price forecasting, yet until relatively recently industry has been unfamiliar with their characteristics and properties. An understanding of the various types of cost model is vital to enable effective cost control and the development of future forecasting techniques. This volume brings together more than 20 seminal contributions to building cost modelling and introduces the major landmarks in progress and thinking in this field: * strategies and directions * explorations in cost modelling * cost-product/process modelling * dealing with uncertainty The strong techniques bias of this book will appeal to construction professionals involved in estimating, as well as researchers and students of building economics.
