Supply chain management for modular construction using building information modeling

This paper presents an example of an integrated con¬struction system that uses building information model¬ing (BIM), the internet of things (IoT), and geographic information system (GIS) technology to improve supply chain logistics management in construction projects, thereby increasing project efficiencies and controlling construction costs. The authors developed and tested a digital twin platform for the proposed system, which allows real-time simulation of logistics in modular con-struction. The proposed digital twin platform uses BIM and GIS as its foundation because BIM includes infor¬mation on the plans, detailed geometry, properties, and quantities of modules, whereas GIS provides geospatial data for the modules along with vehicular information during transport. This system with integrated BIM, IoT, and GIS modules was applied in a new manufacturing company within its first five years. The results show that potential logistical risks and accurate module arrival time can be detected via the suggested digital twin platform. The integrated system proved to be effective in product delivery management tasks.
