In the past decade construction and engineering have changed dramatically, with an explosion of innovative new approaches to construction and new methodologies. By bringing together economic, social and construction/engineering management perspectives, this book offers a unique and comprehensive survey of these approaches and techniques. It presents a history of studies in innovation in construction and engineering, and then presents the most recent models of innovation brokering and risk-management, based on complex project-based industries. Innovation is defined and competing theories are discussed in the light of operational issues. The book covers all aspects, including the importance of construction and engineering 'cultures' in the trades for successful project innovation. It also discusses the role of government and policy makers, the implications of rapid change for the building trades and skilled labour, and the difficulty of measuring innovation quantitatively.
