Abstract
In the last few years, heritage building information modeling (HBIM) methodology has been primarily adopted for documenting and managing historic buildings by creating a digital model. A highly precise model replicating the historic building’s condition is a higher level of development (LoD) HBIM model. If the model allows bi-directional data exchange between the physical entity and the digital model, they are known as digital twins (DTs). A higher LoD HBIM can assist in better simulation, restoration, adaptive reuse, and museum curating. At the same time, DTs can attain real-time structural health monitoring, visitor-flow control, and air quality control. However, creating a DT for historic assets from reality capture, geometry modeling, and information registration via the HBIM process can be intensive work and a financial burden for projects with limited funds, which can make the built heritage steward hesitate to invest. Besides, developing a high LoD DT for built heritage is practically unnecessary for the initial project set-up. The comprehensive development path from the HBIM model toward DT should be an iterative process that can progressively increase information enrichment by considering the combination of project goals, available resources, and expected project outcomes. This research aims to create a framework for sustainable historic asset management that can support stakeholders in achieving better preservation via the HBIM process and work toward DT applications by taking a long-term view. The article applies a use case-oriented approach and divides the HBIM model updating to DT as three stages that increase LoD and twinning rate. The proposed workflow, implementing a stage-by-stage procedure, allows historic preservation projects to make use of HBIM-DT applications with affordability and flexibility, which has the potential to be widely adopted. The framework will contribute to the industry and eliminate the barrier to entry for fund-limited projects to apply the HBIM process and DT applications.
