Indeed in most European countries and American states construction activities now account for approximately 5 to 10 per cent of a nation’s GDP and are typically responsible for the employment of millions of site labourers and professionals. Obviously these figures are sensitive to the general pattern of economic activity. For example, the £30 billion cuts in UK public spending announced in the first coalition budget in June 2010 (the week this foreword was written) could seriously jeopardise the volume of construction output seen in 2011 and beyond, especially as the government procurement arm, the Office of Government Commerce, was merged into the Cabinet Office as part of a cost-cutting efficiency drive in the very same budget! The central point made by this historical commentary on the current economic climate is that to make sense of it, at any point in time, requires economic literacy, and part of this inevitably means that you need to appreciate the nature of the economic transactions that underpin each and every new order for a constructed product. As this Introduction to Building Procurement makes transparent, the world of construction is complicated by the initial negotiation between client and contractors, as no two jobs are quite the same and as a consequence the quality of a project, the time it takes and the cost involved are often unknown variables at the start of the procurement process. As the authors perceptively state at the very beginning of their text: ‘From the client’s perspective the investment is unpredictable in terms of delivery, budget and the standard of quality.’ From my position as a construction economist the two subject areas appear inseparable, but as you can see there is too much to each specialism to fit comfort- ably into one tex t. As a comprehensive work on procurement, however, you will find it difficult to better what is offered in this book. The breadth of experience that it draws on is certainly unique, and together the authors have provided a detailed and clear exposition of construction procurement. The text began its life when Jack Masterman was studying for his PhD in the early 1990s; Brian Greenhalgh subsequently recognised from his significant experience in the industry and academia that this needed to be revised and extended to take account of the various developments of the twenty-first century. Graham Squires, at the other end of his career, contributes an energy and sense of purpose to help bring the long
