Current BIM Systems 4
Published in Jonathan Ingram, Understanding BIM, 2020
Initially aimed at architecture ArchiCAD has now evolved into a full BIM system with its MEP modeller. Graphisoft also produces its own MEP Object library and Toolbox. The library contains an extensive list of MEP specific objects or components. Structural design is done via external systems such as Tekla using IFC to communicate the specific elements. ArchiCAD can export the standard image formats (JPG etc.) and import and export DWG and DXF files (2D drawing files).

The post-processing of modeling through point cloud data is applied in vary fields. In terms of road BIM visualization fields, Intignano (2021) collected the road point cloud data of archaeological sites with the help of a laser scanner, and juxtaposed it with the coordination point for geographical reference through a total station, processed the point cloud through several BIM based tools, generated road shapes that can reflect the texture of archaeological sites, and realized the road visualization of archaeological sites with software programs such as python. As far as the refined modeling is concerned, Murphy, McGovern, and Pavia (2013) constructed parameterized objects of traditional European architectural components using Geometric Description Language (GDL) on the BIM ArchiCAD software platform based on manuscripts from the Vitruvian period to 18th century architectural pattern books. And draw parameterized objects as building components onto laser scanning measurement to create a complete European traditional architecture. In terms of transforming BIM models into finite element models for structural numerical simulation calculations, Barazzetti et al. (2015) utilized point cloud data to transform complex and irregular building components recorded in BIM models into historical buildings; After converting BIM model into FEM model, the degree of damage of building components and physical-mechanical properties of materials are accurately measured, and their values are assigned to FEM to achieve structural numerical simulation analysis.

Therefore, this study proposes a model of cultural heritage management by means of artificial intelligence. Due to the large number of factors which influence each type of element (structural elements, finishing elements, etc.), this research was focused on one of these elements. Therefore, this case study is about the conservation management of the tile panels from the Pavilion of the Emperor Charles V located in the Real Alcazar of Seville (Spain), which was declared an UNESCO World Heritage Site. To generate the model of classification, the J48 algorithm was used on the training dataset. Then, this model was implemented in Geometric Description Language (GDL) for one of the BIM platforms existing in the market (ArchiCAD), and its behaviour was tested in new case studies. This working process can be established as a methodology of developing intelligent H-BIM models, classifying automatically the elements that configure the building and the type of response required by the managers of the model.

BIM has the potential to achieve sustainability given that it aims to provide efficient design, construction, operation and maintenance of buildings (Wong & Fan, 2013). The use of BIM was mandated for Government projects by 2016 (Cabinet Office, 2011), and valued at £46 billion between 2016–2020 (HM Government, 2014). However, a BIM readiness report indicated that 73% of built environment Small and Medium Enterprises (SMEs) have never worked with BIM models (NFB, 2012) and SMEs represent an 85% share of employment in the construction industries private sector (BIS, 2013). BIM models are not just 3D drawings, they allow project team members to add, edit, delete and share real-time information and design specifications using a common data interchange platform. They can also integrate and combine files from alternative computer-aided design software (e.g. Autodesk Revit, Graphisoft ArchiCAD, Bentley Architecture, etc.) into a single file format (e.g. Industry Foundation Classes (IFC)). BIM provides multi-dimensional information of buildings or structures, i.e. the built environment, allowing the identification of a design collision between the multidisciplinary project team; check for accessibility compliances; capture design and material information; supply chain integration and much more.
