Scan to H-BIM, drawing information and model sharing protocols. The case study of the Castiglioni Brugnatelli college (PV)

The paper proposes a reflection on methodological protocols for developing scan to H-BIM information models on historical architecture. The case study is the Castiglioni Brugnatelli College, the first university college in Pavia, founded in 1429. In 1954 became the first lay female college to be established in Italy. The experimentation conducted included the development of drawings and models to provide an updated knowledge base of the collegiate complex’s interior rooms and external environments. The H-BIM model aims to allow the managing body of the complex to develop proposals for maintenance and improvement interventions consistent with the image and historical importance of the building. The goal is to understand the weakness and limits of scan to BIM systems applied to historical architecture. The application of mobile laser scanner systems in Cultural Heritage context cannot fail to consider the architectural decoration and an explanatory need that contemplates the imperfect in all its structural, constructive, and ornamental constructive components.
