Adopting the standardized openBIM methodology, including IFC data models, could revolutionize cultural heritage management. It simplifies documentation and asset management from digital surveying, offering easy access to information and encouraging wider use of the HBIM methodology. The need for detailed documentation of materials for urban mining and sustainability highlights the importance of understanding our built environment, with HBIM playing a key role amidst rapid climate change. However, for HBIM to be fully effective, its adoption needs to expand beyond the construction industry to include heritage authorities.

Integrating various digital survey data poses challenges in data compatibility and requires strong data processing solutions. Achieving interoperability among different software supporting openBIM and IFC models is difficult, as software compliance varies. Promoting the openBIM approach demands awareness and overcoming resistance from stakeholders, while protecting sensitive data needs secure, accessible solutions.

Yet, a standardized openBIM approach enhances collaboration and workflow efficiency, improving documentation, decision-making, and heritage understanding. It supports accurate preservation decisions and advances in Heritage BIM practices. Despite challenges in data integration and stakeholder adoption, the benefits of streamlined operations and heritage preservation are significant. Addressing these barriers is essential for the successful implementation and advancement of Heritage BIM, preserving cultural heritage for future generations.
