Using BIM and GIS Interoperability to Create CIM Model for USW Collection Analysis

Computational tools based on the CIM (City Information Modeling) concept have been developed to support the analysis and project of the urban environment. These tools demonstrate how information modeling technology contributes to the visualization and handling of data in urban management context. A devised solution to get a CIM model is through the interoperability between BIM (Building Information Modeling) and GIS (Geographic Information System) applications. This research proposes this integration to be applied and generate a CIM modeling. The aim is to present an efficient way to take advantage of the BIM modeling data, which have a real probability to be sent to city hall in future as part of the project approving process. Hence, this turns possible the calculation of USW (Urban Solid Waste) production and the planning of their collection with an immediate visual feedback. In this research, BIM and GIS data were integrated through interoperability between .RVT and .GdB files. All data were used together to get a result analysis of the USW production and respective collection in a specific urban region. Also, it was possible to analyze data accuracy per USW collection points from the provided data for each BIM modeling. The simulated CIM modeling in this work allowed the creation of a three-dimensional environment for the visualization of the USW production. Also, it gave support to the analysis of waste collection routes in order to maximize the use of collectors and allowed a preliminary verification of how a building affects the waste production and collection routes in a city.
