Configuring BIM Models to Support a Systems-Driven Visualization Approach: A Case Study

Abstract

Models developed through design and construction are not intended to support facility management. They don’t generally have the life-cycle data and information required or they are not configured to support visualization of model graphics from a system’s perspective. Current implementation for BIM-FM focuses mainly on including facility life cycle data to support space management or asset management. Models are not customized with necessary data and classification that allow for isolating and visualizing components of a specific building system (e.g. supply air). This is necessary in an emergency situation to allow facility staff diagnose the problem associated with the system and its components, identify the problem and make necessary and informed action. In this paper, we discuss requirements for preparing an as-built BIM model to be systems-centric using a case study approach of a two-story science building. A system classification hierarchy was developed to classify the systems and sub-systems of the building. Sixteen systems-centric properties were also defined to search, filter, isolate, and display elements in a specific system or sub-system. The configured systems-centric model will also help facility managers understand the dependencies across different systems to accurately determine impacts across the facility and develop strategies to rapidly respond to any emergency. The case study focused on the mechanical and plumbing systems only. Several example emergencies are discussed and presented.
