Bar charts and Critical Path Method (CPM) schedules used in the construction industry provide answers to 'what' component is to be constructed and 'when'. Most of the commercially available scheduling tools such as Primavera and Microsoft Project used to generate such schedules fail to provide the information about 'where' the component will be constructed, which require spatial aspects of a project. This paper addresses the spatial and temporal characteristics of the project that facilitate the visualization and understanding of the construction schedule. A methodology using Geographical Information Systems (GIS) was developed to represent spatial aspects of the construction progress graphically by synchronizing it with the construction schedule. The spatial aspects corresponding to each activity in the CPM schedule (generated in Microsoft Excel) were depicted by 3D model developed in the AutoCAD. The spatial and scheduling information were linked together in a GIS environment (ArcGIS) to provide the answer to 'what', 'when' and 'where' of the construction planning.
