The goals of lean construction practices and concepts are to increase value, minimize waste, and improve efficiency throughout the building process. Lean construction is based on the lean manufacturing concept from the Toyota Production System which seeks to maximize project completion by reducing non-value-added tasks and improving cooperation between all parties. Respect for people, continual improvement, and the removal of waste, which can be broadly divided into seven categories, overproduction, waiting, transportation, excess inventory, motion, flaws, and underutilized talent, are the cornerstones of lean construction. The idea of value, as seen from the viewpoint of the client, is fundamental to lean construction. By making sure that resources are spent effectively and that the end product meets or surpasses client expectations, this method aims to provide value at every stage of a project. Just-in-time (JIT) scheduling, integrated project delivery (IPD), and Building Information Modeling (BIM) are important techniques that promote lean concepts. While IPD encourages cooperation between owners, designers, contractors, and suppliers, guaranteeing that everyone works toward common objectives, BIM helps improve coordination and visualization, lowering errors and rework.
