Digital Twin of Road and Bridge Construction Monitoring and Maintenance

Road and bridge management are not an easy affair; Therefore, smart way is needed to encourage easier, cost effective, and more efficient construction monitoring and maintenance processes. Currently, road and bridge management has utilized internet of things-based sensing technology and has produced a big data. However, the data is still in silos, so it needs to be arranged into one data. This one data becomes a digital representation or ‘digital twin’ of roads and bridges. The aim of this paper is to present the concept digital twin for road and bridge management especially for construction monitoring and maintenance. This paper also discusses open problem and issues related to implementation of digital twin in West Java Province-Indonesia as a piloting project. In this study, we designed a digital twin architecture for the six-step cycle of monitoring and maintenance of road and bridge construction in West Java which consists of a survey process, technical planning, budgeting, procurement, implementation and service and permission, then the data is integrated into ‘Smart X Platforms’. As a result, we have successfully integrated 15 types of data related to road and bridge management in West Java Province. We also found problems in implementing digital twins for the construction and maintenance of roads and bridges including map availability, license ownership, security system and smart contracts, and dashboard display speed.
