Applications of 4D GIS Model in Construction Management

Abstract

Construction project involves participation of various stakeholders, contractors, and agencies for timely and effective completion. Each activity and resources of contractors are preplanned to avoid delay of project. Planning, designing and scheduling of structure are done with the help of available software’s. But this software’s still lack feature of providing related construction information in 3D model and also there isn’t any system available which can handle all project related information and documents on single platform. 4D Geographic information system (GIS) model is created by inter-linking schedule of activities and computer aided designs (CAD) drawings on GIS platform for G+4 building located in Navi Mumbai, India. The developed model can handle all project related database on single platform. Proposed methodology helps in determining incompleteness and logical errors in scheduling or designing and helps us to determine feasible route for manpower and material movement from different locations to construction site. 4D GIS model maintains spatial data such as different 3D components of structure in separate layers which is geo-referenced spatially and necessary nonspatial information such as dimensions, materials required, schedule, related documents, persons responsible, safety and quality control recommendations, site expenditure and material inventory are stored in attribute tables. This research concludes that GIS model can create real time building construction information database
