Abstract: Construction industry requires a highly accurate planning, scheduling and management of the process of the project which can facilitate the overall optimization of the cost, time and resources. The traditional system of using of AutoCAD drawings, MS Project and Primavera for scheduling does not satisfy the clients in making them understanding the project status and also find time consuming. Hence, an efficient method is proposed in this study implementing Geographical Information System (GIS) as a platform to link the plan of building and its corresponding schedule of executing the construction of building. GIS is relatively an emerging field for managing the spatial and the non-spatial data. The aim of the study is intended to demonstrate methodology of creating the GIS based 4D Model for optimization and real time monitoring of the project. The plan of the building drafted using the drafting software (AutoCAD) and the corresponding schedule of the building generated by Project Management Software (MS Project) were interlinked using GIS platform. This enables the planner to get a clear picture in the planning stage and better control for the progress of the work in the most appropriate manner rather than the conventional methods of controlling the progress of the work with the help of management software. GIS based enclosure also paves the way to include the non-spatial information like bill of quantities, labour requirement, safety recommendations, etc. and can be stored as a tabular form for the corresponding drawing. A case study of one storey residential building at Thangam nagar in Erode, Tamilnadu, India has been selected for the study.
