Application of Scan-to-BIM and geographic information systems in restoring the current status of buildings

Because many existing structures, such as administrative, heritage, or university buildings that were constructed several decades prior, do not have sufficient paperwork and plans, the digital restoration of records for future management is currently facing a great deal of difficulty. Once the Building Information Modeling (BIM) information model is constructed, establish a connection and transmit the database via the Geographic Information Systems (GIS) environment to enhance the efficiency of project design, construction, and operation management. This will also serve as a database for future Smart city initiatives. Additionally, the traditional techniques of assessing existing conditions are labor-intensive and time-consuming, and the drawings of the as-built state are not necessarily correct. This study was carried out to enable the restoration of three-dimensional models of buildings by utilizing cutting-edge technologies such as BIM-GIS. The purpose of this study was to solve the problem that had been identified for Asset Management in Old Building. Building B6, which houses the Faculty of Civil Engineering at Ho Chi Minh City University of Technology (HCMUT), Vietnam National University, Ho Chi Minh City, serves as the case study for this kind of investigation. The first thing that has to be done is to use Scan-to-BIM to create a digital model of Building B6, and then the next step is to upload the BIM model to the GIS platform and check the conflict between each model thereafter. In conclusion, the study comes to a close by presenting its findings and providing an outline of potential future research topics.
