Benefits of integrating BIM and GIS in construction management and control

Generally, a tremendous amount of waste and debris are generated by the demolition of existing buildings. Construction managers and site engineers are encountering difficulties in accurately calculating the volume of these materials, which have big influence on the duration and cost of projects. This paper describes the methodology used in developing a model that integrates Building Information Modeling (BIM) and Geographic Information System (GIS) to facilitate demolition waste management and control for megaprojects. The suggested model aims at facilitating the processes of estimating the quantities of waste by calculating the travel distance between the site, storages, and landfills and related time, as well as computing the number of trucks required for loading and hauling the waste from and to multiple sites. The main goal of this study is to demonstrate how this integrated model will provide construction managers with a comprehensive tool that could substantially benefit them in comparison to solely utilizing BIM. This paper will demonstrate how the model works and explain how it has the edge over using BIM only. The suggested BIM-GIS model will contribute to more green and efficient construction management. A hypothetical case project is given to test the workability of the model.
