Field observations are the first step in the digital documentation process. The purpose of the observation is to identify the assembly elements, their specificity in the current state of things and thus designate groupings of components and data gathering methods, to continue our latest topic about the relation between building information modeling and Reverse Engineering
Making Digital Twins
The usage of a laser scanner and photogrammetry is used to acquire digital data (photogrammetry). This produces so-called point clouds (point clouds), collections of data with precise spatial coordinates. Point clouds, as a result, include geometric and colorimetric information about an item. Regardless of the goal of the HBIM process, which is to provide digital documentation of architectural history, traditional approaches, which involve direct data gathering via sketching and manual measurement, are not excluded. The item is split into wholes in terms of the morphological qualities of its elements, and traditional measurement is often the only way to collect data on the morphological features of particular components, such as decorating parts or other portions of complex geometry. In addition to being a digital representation of a historic building that represents it is physical and shape features, the HBIM model is also an interactively oriented building database in which the geometric model is linked to descriptive data. The production of “digital twins” marks the start of a new technique in which information of the object’s investigated components can be shared and visually communicated, broadening the range of players participating and improving readability by moving beyond the 2D drawing level. As a result of the HBIM process, an archive was generated, which served as a source of knowledge about the historic building’s spatial, structural, and form qualities and a tool for managing future research and decision-making. The ability to save information on landmark structures and the storage, easy changing, and updating of data in interactive databases are the fundamental characteristics of the HBIM method. This method of modeling in a digital environment enables the store and display of intangible data, such as material type and historical data, in addition to geometric and physical representations of the object. In addition, the HBIM approach enables a precise and reliable virtual presentation, with fewer opportunities for misinterpretation and measurement. The creation of HBIM models necessitates a deeper understanding of the nature of individual object elements and the item as a whole, allowing for its deconstruction and reassembly. High application costs, process complexity modeling, and data collection are the main challenges of using the HBIM process (compared to the traditional one). The digital documenting of architectural heritage initially encounters problems such as interpretation of acquired and processed facts, historical documentation dependability, information interpretation, assessment, and monitoring. The extent to which various digital tools will be used is determined by the conditions – accessible technology and the expertise of the specialists.
New possibilities of BIM
The use of information modeling of historical items in the recording and management of historical resources is an important step forward in advancing BIM. The use of the HBIM method enhances awareness of the value of historical heritage as a cultural asset, resulting in the creation of a digital archive that gives knowledge to a broader audience and future generations. Extending the scope of BIM procedures creates new issues for the building industry and necessitates and stimulates collaboration between disciplines. Simultaneously, knowledge exchange is developed, which can drive different research topics and the commercialization of future applications. The HBIM method is an excellent example of collaboration between historians, architects, and engineers. It opens up new areas of action and research to expand knowledge of architectural heritage’s relevance, cultural and economic value.
