Development BIM Model to Manage the Demolition Waste in Iraqi Construction Projects

Abstract

Demolition waste is an important topic in the construction industry, and as a result of demolishing old buildings, very large amounts of wastes are created and must be properly managed. The authors assumed that the building was demolished.The research aims to use the BIM model (Building Information Modeling) in demolition waste management because it provides reliable information for the decision-makers. The idea of the research was applied to the Deanship of Medicine College as a case study and was modeled using Revit software. Through modeling, the quantity takeoff is  extracted for materials and by utilizing the ratios of field survey from a previous researcher, demolition waste was sorted.  The results showed the process to calculate the volume of demolition for concrete and brick, as well as the process of sorting the demolition waste to (on-site reuse, reuse another site, recycle, and landfills). The authors found that through this research, the number of trucks required to transport demolition waste to its appropriate locations can be calculated.
