ABSTRACT

Building Information Modeling (BIM) is regarded as one of the most promising developments in the Architecture, Engineering, Construction and Facility Management industry due to the ability to enhance communication between the stakeholders involved over the whole Life-Cycle (LC) of a building. Although BIM was initially intended to support design and construction processes, activities of the construction industry trend to building renovation and deconstruction management in industrialized countries. Potential benefits of using BIM in existing buildings are related to efficiency, saving time and cost during renovation, quality control and monitoring, energy simulation, indoor navigation and emergency responses. Manual as-built BIM creation is a labor intensive, time consuming and subjective procedure. Therefore, intense efforts have been made in recent years to automate the creation of as-built BIM models from surveying data. Results are promising but more research should be done to address point cloud processing, increasing model requirements and interoperability.
