Abstract
Abstract. This paper introduces some studies developed regarding the Medicea Villa at Poggio a Caiano, in Italy. The monumental building was built by Lorenzo de’ Medici and his heirs following the design of the famous architect Giuliano da Sangallo, between 1485 and 1520. The Villa embodies many of the typical features of the Italian Renaissance, added a monumental double circular stairway in the front façade during neoclassical times, heading to the upper balcony surrounded by a balustrade. The Villa was surveyed taking advantage of Terrestrial Laser Scanning and Digital Photogrammetry, in order to produce a detailed model to be translated into a HBIM digital prototype then. The Scan-to-BIM approach was obtained with a generation of semantics and components proper of Sangallo’s architectural grammar, first of all defining the object, then geometry, and then their parametrization. This process led to a model of the exteriors, used to better understand the architectural composition of the volumes, to make some hypothesis on its shape according to the original architect’s drawing in the Taccuino Senese, on its general structural behaviours, to understand the limits of a process and the perspective of a research that goes from a digital survey to the HBIM environment.
Highlights
1.1 Aims of this researchA first aim of this research is the creation of a complete and describable pipeline that comes from the Terrestrial Laser Scanning (TLS) and photogrammetric image-based survey of a Renaissance Architecture, considers the integration of different survey and measurement techniques, the verification of the real achieved Level of Accuracy, forms a point cloud to be imported into a BIM environment
The exterior boundary and all the significant structural abstractions needed by a Finite Element Modeling software were loaded directly from the Historic Building Information Modeling (HBIM) geometric database authored in Revit, imposing loads and constraints according to the relationships among building elements
A HBIM digital model is conceived to improve information quality and quantity as the knowledge on the existing building grows; when this approach is applied to an existing monument, just like Villa Medicea in Poggio a Caiano, data collection becomes a complete digital repository aimed at the knowledge of the architectural heritage
Summary
A first aim of this research is the creation of a complete and describable pipeline that comes from the TLS and photogrammetric image-based survey of a Renaissance Architecture, considers the integration of different survey and measurement techniques, the verification of the real achieved Level of Accuracy, forms a point cloud to be imported into a BIM environment. The research wishes to investigate how much can be reversed from the monument itself into a new digital model in a particular case study, taking care of the accuracy of the model if compared to the built environment. The gap between the existing and the model is considered as the boundary to be investigated by the following researches
