The Smart Structural Integrity Monitoring System (LiFY-S) was co-developed by LeafIoT and the Drainage Services Department of the Hong Kong Special Administrative Region to enhance construction site safety. This cutting-edge solution revolutionises structural monitoring by integrating Artificial Intelligence of Things (AIoT) sensing, big data analytics, structural simulation, and digital twin technology, transforming traditional surveying methods into a real-time continuous monitoring system with a developed sensitivity six times greater than conventional techniques.
Key components of LiFY-S include real-time displacement monitoring sensors that precisely measure structural micromovement; a centralised AIoT cloud platform for monitoring structural health and integrity; and seamlessly integrated with smart watches that deliver early warning alerts to design and construction teams on excessive movement, ensuring timely communication and investigation.
LiFY-S optimises resource allocation in structural health monitoring, greatly reducing deployment costs to less than 30% of traditional manual surveying while significantly improving operational efficiency and site safety. As a transformative solution for the construction industry, LiFY-S sets a new benchmark for safety, efficiency, and innovation in structural integrity management.
