The article focuses on the analysis of the construction technique of the star vault designed by the famous Bohemian architect from the Baroque period, Jan Blažej Santini-Aichel. The vault covers St. Bernard’s Chapel in the Plasy Monastery and represents a masterpiece in Santini’s late career. The authors try to understand its construction technology with the help of modern surveying methods. The shape of the vault structure is complex, therefore a detailed geometrical survey of both intrados and extrados was performed. The data collected in situ, photogrammetric blocks, were used as a basis for the modeling of the vault shape. An accurate 3D model and HBIM of the structure were generated, using a novel Scan-to-BIM process based on the integrated use of a different Grade of Generation and primitive extraction to support the modeling. This survey is part of a program to implement a vault database addressed to detect permanencies and mutations in the construction techniques across Europe, that gives back unexpected, and mostly unknown, richness of vault construction patterns.
