Abstract
In the construction field, the Building Information Modeling (BIM) methodology is becoming increasingly predominant and the standardization of its use is now an essential operation. This method has become widespread in recent years, thanks to the advantages provided in the framework of project management and interoperability. Hoping for its complete dissemination, it is unthinkable to use it only for new construction interventions. Many are experiencing what happens with the so-called Heritage Building Information Modeling (HBIM); that is, how BIM interfaces with Architectural Heritage or simply with historical buildings. This article aims to deal with the principles and working methodologies behind BIM/HBIM and modeling. The aim is to outline the themes on which to base a new approach to the instrument. In this way, it can be adapted to the needs and characteristics of each type of building. Going into the detail of standards, the text also contains a first study regarding the classification of moldable elements. This proposal is based on current regulations and it can provide flexible, expandable, and unambiguous language. Therefore, the content of the article focuses on a revision of the thinking underlying the process, also providing a more practical track on communication and interoperability.
Highlights
In the last decade, there has been a revolution within the construction sector that aims to the digitization of the entire building process
The United Kingdom, Germany and countries of Northern Europe are among the front-line players in the adoption of this system
Their work has led to the formulation of national standards for the realization of these 3D models: such as the English BS EN ISO 19650 of 2018 that was born from the homonymous ISO standard and replaces the previous BS 1192 and PAS 1192 [1,2,3,4,5,6,7]
Summary
There has been a revolution within the construction sector that aims to the digitization of the entire building process. At the base of this dynamic, there is the increasing demand for the formulation of a Building Information Model. This design and management tool of the building system sees a deep-rooted presence in some states, its methods of use are constantly evolving. Thinking of the Italian context and the heterogeneity of the elements that compose its urban fabric, structured regulatory instruments are indispensable. These allow an agile use of BIM in all conditions and in the case of HBIM. They must demonstrate maximum flexibility and interoperability with regard, in particular, to the modeling of existing historic buildings
