Construction projects around the world have a significant impact on our environment, both on a local and a global scale. Every stage of the construction process has a measurable environmental impact: the mining processes used to source materials, the transportation of these materials to the building site from sources around the world, the construction process itself and the waste …

Taiichi Ohno, considered the father of Toyota Production System, created a lean manufacturing framework, which was based on the idea of preserving (or increasing) value with less work. Anything that does not increase value in the eye of the customer must be considered waste, or "Muda", and every effort should be made to eliminate that waste.

All steps in the process should be carefully mapped out to determine what activities are involved. Take into account labor, information, materials, and equipment needed for each activity. Any steps in a process that don't add value for you client should be eliminated. Eliminating Waste. Lean construction is accomplished by cutting out waste.

Ironically, this often occurs when taking steps to eliminate the other types of waste. Flow of Work Processes. The ideal state of a Lean construction project is a continuous, uninterrupted workflow that is reliable and predictable. The sequence is key in construction; you can't start building the frame until the footings are set, for example.

Waste reduction in order to improve performance is one of the basic concepts of lean thinking. In general, project managers tend to conceptualize "waste" as physical construction waste, but there are noticeable wastes in the construction processes which are named "non value-adding activities" by lean construction theory.
