Waste in the construction industry has been the subject of several research projects around the world in recent years. It is commonly acknowledged that a high level of waste exists in construction. Since construction has a major and direct influence on many other industries by means of both purchasing inputs and providing the products to all other industries, eliminating or reducing waste could yield great cost savings to the society. This book therefore assesses the level of knowledge of lean concepts among construction practitioners and how these concepts could be applied in the construction industry to minimize materials wastage. The results of this study should enable building organizations to improve project performance and enhance value for individual customers, and also have a positive impact on the national economy.
