Tangible and intangible benefits of building information modelling (BIM) in heritage buildings presents a constant debate around the ‘value add’ of heritage building information modelling (HBIM). HBIM can create an avenue for detailed modelling of heritage elements in the building envelop, documentation of unique cultural attributes and a platform for maintenance during operational phases. And the debate is often more about the ‘how’. Currently, traditional 2D drawings form the basis for maintenance decisions which makes the process cumbersome. Moreover, such drawing sets are often incomplete. This study aims to leverage BIM from a maintenance perspective to develop a standardised workflow for heritage building maintenance. A ‘simulation’ based methodological approach was adopted in this study. A Leica BLK360 3D scanner was used to capture 100- point cloud scans, then applied to create HBIM profile for an existing heritage roof, service ducts, clock and storage space. Autodesk Recap Pro was used to register the point-cloud and analyse the roof profile. The results revealed critical risk areas to the building roof. Exterior images were relatively similar to the interior point cloud. The workflow developed provides a standard workflow for future maintenance in heritage buildings. The results directly impact decision making by policy makers for transformation to HBIM.
