In rapid, construction projects, it is not possible to manage the project through the conventional ways. It has been observed many times that the productivity of the construction depleting and leads to rework and produces many wastages such as over production, inventory, unnecessary transportation, workers displacements, over-processing, defect, waiting of materials, unused employee creativity, work accident, etc. In this Project focus on Lean Preconstruction Management i.e. Lean’ is just way far greater than just a philosophy. In construction industry, eliminating waste and satisfying client’s requirements is of utmost importance. Quality Assurance can be only attained if everything goes with standards and advanced thinking and furthermore implementation of newest trends in technology. Lean Construction Technology is one of them tied up for betterment of Construction Industry. Objectives of this research are to identify and record perception of different construction project participants on lean based wastes on construction sites and quantify them via. Questionnaire Survey, to study and demonstrate Value Stream Mapping on residential projects as a Lean Tool and identify possible benefits emerging from application of this tool and to increase output value through a systematic consideration of customer requirements; So this report aims to overview and discuss the applicability of lean principles and its techniques used in construction project which helps to reduce wastages in construction and brings the quality of work in product developing process with raising the profit level and also which factors affects to adopt lean management in construction has discussed with the current construction practices and past studies. This report review on the principles and techniques of lean management currently used in civil industry to reduce various types of waste and discuss the obstacle of lean management in construction in construction. This research study is limited to residential construction projects only.
