Abstract
Emerging remote inspection technologies are addressing the challenges of conventional building work inspections by reducing time, cost, and safety risks for inspectors, while also improving overall effectiveness. These technologies involve data collection, information extraction, and compliance checks, highlighting the need for a comprehensive understanding to enable the adoption of more efficient and secure inspection methods. This paper comprehensively reviews cutting-edge technologies, sensors, platforms, and data processing methods applicable to remote inspections across diverse building elements. It evaluates each technology’s suitability for specific building components based on key criteria, including inspected item properties and potential for assistant-based or remote inspection, with emphasis on video-based methods. Furthermore, the analysis considers technology capabilities for automation, real-time functionality, and policy implications for implementation.
