Building Information Models (BIMs) are used in the architecture, engineering, construction, and facility management (AEC/FM) domains for a variety of purposes ranging from monitoring the construction or renovation of a facility to managing the facility during day-to-day operations. The representations of BIMs were originally designed to handle the precise and perfect data from a design model. However, actual buildings are never perfect and often deviate significantly from the design.

The goal of this research is to develop methods for representing the “as-built” or “as-is” conditions of a building. We are working to understand the differences in representational requirements for as-built BIMs as compared to as-designed BIMs. We are studying several aspects of the representation problem, including methods to represent occluded regions, data uncertainty, levels of detail, and metadata.
