Lean Construction is proven to significantly reduce construction costs and speed delivery. The problems of management and supply chain logistics are essentially the same in all industries; consistently getting the right quality of materials and people, in the right quantity, in the right place, at the right time. Irregularity of workflow causes uncertainty, waste and delay. Numerous studies have highlighted the waste in construction, and it is a fact that infrastructure costs 20% more in the UK than in most of Europe. Lean is a proven methodology to reduce waste, smooth workflow and hence deliver projects earlier for less cost.
