A Design Approach to Support BIM for Existing Structures

Nowadays, Building Information Modeling (BIM) is a common design approach to support the life cycle of projects in the field of Architecture Engineering Construction (AEC). New constructions’ projects require a BIM modeling to provide digital information within a 3D digital mockup. The main target is to reduce time and cost related to the elaboration of additional and not integrated documentation. This issue is also common in projects focused on the renovations of existing buildings. In fact, the BIM approach provides tools to improve interoperability between different software to integrate analysis and simulations within the architectural representation. The renovation projects require reverse engineering tools and methods for the 3D modeling of existing structures. One of the issues concerns the digital photogrammetric survey of glass surfaces. This paper proposes a design approach to support BIM phases for already existing structures with a test case focused on a hallway with a continuous glass wall.Published292-3007TM.
