Site layout planning is a critical factor for the successful execution of any construction project. As cities develop, site logistics becomes an essential planning aspect for any construction project. Project sites in tight neighbourhoods lead to not just space constraints but also challenges to approach, material handling, and pollution control. Site layout planning has been in practice in the industry, however, limited to a traditional approach of a pre-construction assignment, rather than a dynamic system to analyse construction sites in terms of both space and time. Material handling and delays related to waiting for materials add to a considerable amount of waste during the execution of projects. The paper here explores minimisation of wastes on construction sites, as defined by Lean Construction, using a BIM model highlighting the construction site layout planning to visualise the various aspects of space constraints, access routes, safety considerations, and a visual approach to progress monitoring and reporting. The research follows a case study analysis to develop an understanding of the present scenario, based on which a proposed scenario has been developed to elaborate on the improvements. The paper concludes with a summary of wastes observed and minimised, along with benefits observed through BIM implementation.
