Lean concepts, though born in the manufacturing industry, have since made their way to the construction industry. Although the general approach towards lean construction tends towards making construction more like manufacturing through standardization, practitioners and researchers soon realized the dynamic nature of construction project management and attempted to implement lean concepts accordingly throughout the various phases of the project. In a broad sense, lean concepts aim at minimizing waste and maximizing value which can be related to cost, quality, and time. Therefore, lean is not a set of tools and techniques, but a way of thinking that can be catered to suit the needs of the application under study. Typical categories of waste in construction include completing activities ahead or behind schedule, unnecessary transport (double hanging), material stocks, and waste of untapped human potential among others.
