Abstract
Abstract. There are multiple conservation challenges related to decorated surfaces, the majority are intimately linked to its documentation. This paper draws on wall paintings as a representative of decorated surfaces, arguing the importance of considering its fourthdimensionality – space and time – in its conservation and documentation. To that end, we propose the use of Building Information Model (BIM) as a platform to consolidate this approach together with various documentation techniques used for the conservation and management of wall paintings. This paper exemplifies this method with a case study of Myin-pya-gu Temple in Old Bagan (Myanmar); firstly, reviewing the different techniques used to document the temple and wall painting (photography, photogrammetry, laser scanning, reflectance transformation imaging (RTI); and secondly, discussing the data integration within a BIM environment. This position proposes a transition from a two-dimensional to a four-dimensional approach in wall painting conservation, potentially opening up possibilities of documentation, monitoring, simulation, or dissemination. Ultimately, the case study of Myin-pya-gu has the objective to introduce the use of HBIM as a platform for consolidating the documentation of decorated surfaces.
Highlights
The conservation challenges related to decorated surfaces are manifold, and mainly related to material heterogeneity, variation in size, and its intimate relation to the structure
We introduce the possibility of using Building Information Model (BIM) as a platform to consolidate this fourdimensionality approach together with various documentation techniques related to the conservation and management of wall paintings
Photogrammetry, and Reflectance Transformation Imaging (RTI) are all likely to be referenced within the BIM environment, it is useful to look at an external method to link all of these data types like the one in Pamart et al, 2019
Summary
The conservation challenges related to decorated surfaces are manifold, and mainly related to material heterogeneity, variation in size, and its intimate relation to the structure. Wall paintings are an essential component of decorated surfaces, highly significant because of their intimate connection to its support and its relation to the context. We introduce the possibility of using Building Information Model (BIM) as a platform to consolidate this fourdimensionality approach together with various documentation techniques related to the conservation and management of wall paintings. It discusses several approaches to data integration for wall paintings within a BIM environment using the case study of the Myin-pya-gu temple in Old Bagan, Myanmar (Figure 1).
