Various types of spaces for different purposes on various positions at various times are required to execute various construction activities on a construction site. Labors, equipment, materials, temporary facilities, and structure to be developed share the limited space available on a construction site. Planners use four-dimensional (4D) CAD modeling of the execution sequence to understand and generate the space requirements. The 4D CAD modeling simulates the construction process by linking execution schedule with a 3D model to visualize the construction sequence. 4D modeling is found helpful in the construction space planning. However, 4D CAD modeling lacks in considering the topography and surroundings when construction is in the hilly regions. In the present study, a geographic information system (GIS) has been utilized for the space planning. GIS facilitates the modeling of topography and existing surroundings. The components corresponding to different activities in the schedule and multiple types of spaces corresponding to various activities defined in the execution schedule have been generated in the SketchUP. A GIS-based procedure has been developed in ArcGIS 10, a GIS software, that enables identification and computation of the construction space conflicts before actual implementation of the schedule.
