In this episode of "The Architectural Technologist" podcast, Jonathan and Ethan delve into the crucial topic of Building Information Modeling, exploring the nuances between Open BIM and Closed BIM. They offer listeners a comprehensive understanding of these two approaches, highlighting the importance of interoperability and the challenges that come with software dependency in construction modeling.
The duo kicks off with Jonathan explaining Closed BIM systems, emphasizing how they rely heavily on particular software programs which can impose limitations on project collaboration and future-proofing. They transition into discussing the liberating potential of Open BIM, where IFC formats foster collaboration across diverse software environments like Vectorworks, ArchiCAD, and Revit. Jonathan shares a personal project experience illustrating the seamless sharing of data among different parties, reinforcing Open BIM’s practicality.
As the conversation unfolds, Ethan raises stimulating points about the contractual and project management aspects of BIM projects. He shares insights from a previous government project to highlight the necessity of clear agreements on file versions and single-source authority to prevent confusion. Jonathan further discusses the leadership roles needed to maintain a "single source of truth" in BIM management and how tools like Solibri can be utilized for effective clash detection in complex projects.
Open vs. Closed BIM: Open BIM allows for improved interoperability and collaboration, enabling various software environments to communicate effectively. Closed BIM tends to restrict this due to software dependency.
Single Source of Truth: Effective BIM management requires leadership to maintain a single source of truth and manage file versions to ensure consistent project communication.
Interoperability is Key: One of the main tenets of BIM is interoperability, making Open BIM essential for long-term project sustainability and adaptability.
Future-proofing with Open BIM: Open BIM approaches future-proofing better, as they aren’t tied down to a singular software platform, which could become obsolete over time.
Leadership in BIM Projects: Leadership and management in BIM are necessary to handle different facets of a project, including software usage agreements and managing contributions from multiple stakeholders.
