Building Information Models for Monitoring and Simulation Data in Heritage Buildings

Abstract

ABSTRACT:This paper analyses the use of BIM in heritage buildings, assessing the state-of-the-art and finding paths for further development. Specifically, this work is part of a broader project, which final aim is to support stakeholders through BIM. Given that humidity is one of the major causes of weathering, being able to detect, depict and forecast it, is a key task. A BIM model of a heritage buildingenhanced with the integration of a weathering forecasting model -will be able to give detailed information on possible degradation patterns, and when they will happen. This information can be effectively used to plan both ordinary and extraordinary maintenance. The Jewel Tower in London, our case study, is digitised using combined laser scanning and photogrammetry, and a virtual model is produced. The point cloud derived from combined laser scanning & photogrammetry is traced out in with Autodesk Revit, where the main volumetry (gross walls and floors) is created with parametric objects. Surface characterisation of the façade is given through renderings. Specifically, new rendering materials have been created for this purpose, based on rectified photos of the Tower. The model is then integrated with moisture data, organised in spreadsheets and linked to it via parametric objects representing the points where measurements had been previously taken. The spatial distribution of moisture is then depicted using Dynamo. This simple exercise demonstrates the potential Dynamo has for condition reporting, and future work will concentrate on the creation of a complex forecasting model to be linked through it.

From Point Cloud Data to Building Information Modelling: An Automatic Parametric Workflow for Heritage

“…Although according to Facundo et al [77] Autodesk Revit currently leads the ranking of use in BIM publications in heritage, this software does not solve the problems of surface modelling [52] by itself. In this sense, the Rhino+Grasshopper-ArchiCAD combination demonstrates the possibilities of a new working scenario based on interoperability.…”

“…However, several studies [49,50] implement these tools for specific objects, but not for building construction units. Finally, the work by Tommasi et al [51] brings together diverse software in the market for reverse engineering in BIM applied to historical elements, whereas Pocobelli et al [52] integrated organised moisture data into spreadsheets and associated it with parametric objects development through Dynamo. In addition, there are different reconstruction methods in the scientific literature [53][54][55][56][57][58][59][60][61], most of which use the Delaunay triangulation [54]. Surface reconstruction is the process of rebuilding geometry from the scanned point cloud.…”

As-Built BIM for a Fifteenth-Century Chinese Brick Structure at Various LoDs

“…Provenance of brick can be traced by studying these inscriptions. Nondestructive techniques can be employed to detect physical properties at the brick level, such as moisture content [55]. The self-defined IFC parameters provided by OSS tools enable BIM to be a historic brick database that integrates geometric data with dating, provenance and damage types.…”

Digital Technologies for Inclusive Cultural Heritage: The Case Study of Serralunga D’alba Castle

“…The HBIM modeling for conservation is still representing a question to resolve. BIM-based platforms do not represent a suitable technique for heritage conservation therefore they are substituted for most conventional CAD (Computer Aided Design) tools or are integrated by specific software add-on (Pocobelli et al, 2018). About the project in question, a different approach was developed taking into account the limits and the potentialities of the BIMbased platform used for the information modeling.…”
