Lean Construction method is considered the core principle behind the Identification and Elimination of various wastes in construction. While there are many Conventional Lean Tools like work standardization, doing it right first time, Audits, Just in Time etc., Lean construction identifies and deals with seven forms of waste which is nothing but nonvalue adding items in construction and also suggests ways and means to eliminate them. As such material wastage can be easily quantified, labour wastage and non-value-added activities by labour was much higher compared to material wastage generated in the construction sites. While, Lean production attempts to integrate the concept of transformation, flow and value, a method such as Last planner when implemented for various finishing activities in building projects, there really exists a sense of deep involvement and a great achievement of the project goal. We discuss in this paper the methodology adopted to implement the Last Planner tool of Lean construction and the improvement thereafter.
