A Novel Step Toward Repetitive Projects Scheduling Using Geographic Information Systems

摘要

Unique scheduling challenges are presented by the construction projects having repetitive activities. The present study dealswith the development of a scheduling tool to meet the requirements of projects having repetitive activities. Generally, theschedule of a repetitive construction project is made by using commercially available scheduling tools like Primavera andMicrosoft Project. The link between 2D drawings/3D components and repetitive schedule is missing in these schedulingtools. The literature indicates the use of 4D modeling in case of non-repetitive construction projects to establish this link. In4D modeling, a graphical simulation of the execution sequence is developed by linking 3D components with the scheduleof a facility to be developed. 4D modeling tools lack in certain features such as generating/updating schedule, linking 3Dcomponents with schedule, and consideration of surroundings into a common platform. Geographic information systemsbasedenvironment has been explored in the present study for the development of the tool for repetitive scheduling, linking3D components with the repetitive schedule, and to develop 4D model of the execution sequence of a repetitive constructionproject. 3D components developed for 4D modeling were also used for cost estimation. 4D model of the execution sequenceand cost estimate together constitutes a 5D system for repetitive construction projects.
