In the wide scenario of heritage documentation and conservation, the multi-scale nature of digital models is able to twin the real object, as well as to store information and record investigation results, in order to detect and analyse deformation and materials deterioration, especially from a structural point of view. The contribution proposes an integrated approach for the generation of an n-D enriched model, also called a digital twin, able to support the interdisciplinary investigation process conducted on the site and following the processing of the collected data. Particularly for 20th Century concrete heritage, an integrated approach is required in order to adapt the more consolidated approaches to a new conception of the spaces, where structure and architecture are often coincident. The research plans to present the documentation process for the halls of Torino Esposizioni (Turin, Italy), built in the mid-twentieth century and designed by Pier Luigi Nervi. The HBIM paradigm is explored and expanded in order to fulfil the multi-source data requirements and adapt the consolidated reverse modelling processes based on scan-to-BIM solutions. The most relevant contributions of the research reside in the study of the chances of using and adapting the characteristics of the IFC (Industry Foundation Classes) standard to the archiving needs of the diagnostic investigations results so that the digital twin model can meet the requirements of replicability in the context of the architectural heritage and interoperability with respect to the subsequent intervention phases envisaged by the conservation plan. Another crucial innovation is a proposal of a scan-to-BIM process improved by an automated approach performed by VPL (Visual Programming Languages) contribution. Finally, an online visualisation tool enables the HBIM cognitive system to be accessible and shareable by stakeholders involved in the general conservation process.
在遗产文献和保护的广泛背景下，数字模型的多尺度性质能够复制实物，同时存储信息并记录调查结果，以便从结构角度检测和分析变形和材料劣化。本研究提出了一种生成 n-D 丰富模型（也称为数字孪生）的集成方法，该方法能够支持在现场进行的跨学科调查过程，并遵循所收集数据的处理。特别是对于 20 世纪的混凝土遗产，需要采用集成方法来使更成熟的方法适应新的空间概念，在这种概念中，结构和建筑通常是一致的。本研究计划展示都灵展览厅（意大利都灵）的文档处理过程，该建筑建于 20 世纪中叶，由 Pier Luigi Nervi 设计。HBIM 范例被探索和扩展，以满足多源数据的要求，并适应基于扫描到 BIM 解决方案的成熟反向建模过程。该研究的最相关贡献在于研究使用和适应 IFC（工业基础类）标准的特性以满足诊断调查结果归档需求的机会，以便数字孪生模型能够满足建筑遗产背景下的可复制性和与保护计划后续干预阶段的互操作性要求。另一个关键创新是提出了一种改进的扫描到 BIM 过程的提案，该过程由 VPL（可视化编程语言）贡献实现自动化。最后，一个在线可视化工具使 HBIM 认知系统能够由参与一般保护过程的利益相关者访问和共享。
