Implementation of Lean Scheduling in Real Estate Industry: A Review

Abstract

It is observed that every construction project is unable to perform as per planned objectives as it faces variances in terms of cost, time, quality, safety, specifications, liable to various constraints pertaining to it. Conventional Scheduling techniques that uses push approach has to perform each activity right, the first time- every time in order to make the forthcoming activities follow the schedule. In this study we have introduced Pull Scheduling approach to overcome the delays resulting from wastes in a real estate project. Waste's typical cost as Construction businesses have started using Lean Construction to reduce waste and boost productivity. The proportion of project costs that do not include performance costs ranges from 5.38% to 14.70%. In order to implement lean concepts, which place a strong emphasis on waste minimization and efficiency improvement, building sites in India must first detect waste and its underlying causes. Lean Scheduling (LS) was employed to address efficiency and waste problems and to adapt to the challenges of the construction industry as a future project management philosophy. A comprehensive literature review is carried out to determine real time issues faced in real estate industry using a pilot questionnaire survey and overcoming those challenges using lean tools. Finally, a method for choosing the most fitting lean resources by pull scheduling was suggested. The key contribution of this study is to reinforce the decision-making capacity of the builders in their choice of the most suitable construction-coordinated method on real estate project.
