| Outline of Final Research Achievements |
Infrastructure asset management is a framework for achieving sustainable infrastructure. Generally, the management focuses on the low life-cycle cost in a process of construction, maintenance, rehabilitation, and replacement. Based on this framework, a 3D geometric model is often generated based on construction information modeling (CIM). Moreover, there is a need to refer to maps, engineering drawings, databases, and technical documents in asset attributes acquisition by many engineers. Therefore, we focused on ground investigation and inspection using mobile devices with crowd sourcing approaches. We aimed to assist investigators in infrastructure asset monitoring with location-based applications. We proposed and evaluated our location-based investigation application for facility management based on CIM. Through our experiments, we explored and clarified several issues in infrastructure asset monitoring using mobile devices.
