Meisa Deploys Unmanned Drone Station at Yeosu Island Construction Site

## Meissa, Opening New Horizons for Smart Construction in Island Regions with Unmanned Drone Stations Meissa, a company specializing in spatial information platforms, has proudly been selected for the Ministry of Land, Infrastructure and Transport's Smart Construction Alliance's 2025 technology demonstration support project, embarking on an innovative challenge for the future of domestic construction sites. In collaboration with Kolon Global, Meissa aims to lead a paradigm shift in the construction industry through a demonstration of 'Island-Specialized Drone Station-Based Digital Twin Construction' at the second section of the Hwatae-Baegya road construction site in Yeosu, Jeollanam-do. The core of this demonstration project lies in 'unmanned long-distance control,' transcending the limitations of existing construction sites. The method of remotely and autonomously managing construction sites spanning two different islands via DJI Dock 3 drone stations is expected to fundamentally resolve the inefficiencies of process and quality control, which previously involved manual work by traveling between islands by boat. This aims to innovatively reduce the chronic time and cost burdens in island regions through Beyond Visual Line of Sight (BVLOS) long-distance automated flights. Meissa has already obtained BVLOS flight approval from the Ministry of Land, Infrastructure and Transport and successfully designed a stable long-distance automated flight scenario covering both island sections. Drones collect precise data through regular flights, as well as ad-hoc flights at necessary times for each construction process. The collected data is automatically generated and analyzed into various outputs such as 2.5D orthophotos, point clouds, BIM overlays, earthwork volume calculations, and progress reports through the Meissa platform. This plays a crucial role in building and managing the digital twin of the site in real-time. Notably, the Hwatae-Baegya section, the site of this demonstration, presents all the challenging conditions for implementing drone solutions in construction, including communication blind spots, unpredictable weather deterioration, and a lack of human accessibility. Meissa aims to prove the practical applicability and stability of construction drone solutions by achieving regular and repetitive unmanned control even in such highly challenging environments. While drones have previously played auxiliary roles such as photography or surveying at construction sites, this demonstration is highly significant as it establishes an integrated automated control infrastructure centered around drone stations, encompassing the entire process from data collection to precise analysis and automated report generation. The ability to resolve problems that previously required human intervention – such as cumulative fatigue from inter-island travel, risks of quality control omissions, and delayed responses to unforeseen situations – with a single unmanned station is considered the project's greatest strength. Ha Chang-sung, Meissa's Business Team Leader, emphasized, "This demonstration will be a major turning point, going beyond simple technology application to verify the practical feasibility of unmanned automatic control even in harsh sites difficult for human access." He added, "Based on this experience, we plan to propose a standard model for digital twin construction in island regions, and actively promote the commercialization and universalization of station-based unmanned control solutions." With the know-how and technological capabilities gained through this demonstration, Meissa is expected to prove the expandability of this smart construction model to all hard-to-access construction sites, including outlying areas, mountainous regions, and plants, thereby positioning itself as a leader in the development of smart construction technology in Korea.
