Decision Making in Real Estate Developments Based on Building Information Modeling – BIM

Abstract

This work presents the development of a multicriteria method to evaluate real estate investments based on Building Information Modeling (BIM). Information on possibilities in construction, renovation, expansion, acquisition or rental of buildings is used to enable a decision-making process. The BIM digital models contain building information from planning, execution and as built. The model contains the different representations of top, front view, plants and internal cuts besides the volume. The elements are refined and have the digital representation of data or information of a real estate business project and bring diverse possibilities of analysis. The choice among the available undertakings and the investments to be made is a complex problem that involves relationships between the goals and criteria of each project. The proposed method classifies the undertakings projects using objective criteria based on information automatically obtained from the digital models. It also considers intangible criteria, which are subjective evaluations based on the experience of specialists in the area. This comparative method among project alternatives has proven to be feasible and quite useful, as shown in the case study presented, and it can be further improved by developing a recommender system based on historical data from previous evaluations.
