This paper is aimed to providing knowledge and help in discovering types of buildings in Casale Castello, by recognizing and understanding their structural elements using B.I.M. technology. The presented approach allows generating a recognizable digital spatial configuration of the main structural elements of buildings in Casale Castello village which is examined in this paper through the representation of its urban development. Under this perspective, analysis and representation of the city building logic and their wall types have a noteworthy interest for investigating the guiding principle of the town planning evolution through BIM methodology. It is carried out the analysis and cataloguing of masonry walls types that testifying the development and the reflection of the urban evolution based on the constructive techniques. Like for other villages Klaiber, Lavedan and Piccinato stated the difficulty to chronologically establish the various types of medieval settlement, as well in Casale Castello its impossible to find historical documents on its develop. Using B.I.M. methodology its easy to recognize the different structural element characterizing the buildings in Casale Castello. Through BIM method the digital representation became an efficient device for the catalogation and structural analysis of constructive elements. BIM is a building design methodology characterized by the creation and use of coordinated, internally consistent, computable information on building projects during the design and construction process. The structural elements behavior is analyzed by digital models. It is shown how, using building information modeling technology, the modern houses design has become more flexible, economic, fast and satisfying than traditional 2D drawing representation methods. The information may be refer on full life cycle building manufacturing, from design phase to that of use and maintenance, passing through the implementation phase.
