Building an Unmanned Safety Inspection System to Enhance Management Precision

Ensuring Inspector Safety; Applications Accepted Until August 7

The Seoul Metropolitan Government announced on July 28 that it is publicly inviting submissions for "unmanned safety inspection new technologies," which utilize robots, drones, and data analysis technologies for the inspection of bridges that are difficult for people to access directly.

The city plans to establish an unmanned safety inspection system that can examine confined or elevated spaces inside bridges, thereby enhancing the precision of safety management and ensuring the safety of inspectors.


For example, at some Han River bridges, the depth of certain internal spaces in Seongsan Bridge is only about 1.2 meters, with a width of just 1 meter, requiring inspectors to crouch or crawl to move through, while at Olympic Bridge, the main tower is as tall as 88 meters, necessitating work at significant heights to inspect cable conditions.


To address these limitations, the city will hold an open call to discover innovative technologies. Any business or organization that possesses relevant new technologies or products—such as robots, drones, sensors, non-destructive testing, or data analytics—can participate, regardless of location. The application period runs until August 7.


The submitted technologies will undergo a comprehensive assessment by a selection committee, including technology presentations and demonstrations. About three entries will be chosen in the first round, and from September to December, real-world pilot tests will be conducted on Han River bridges such as Seongsan Bridge and Olympic Bridge.



The final evaluation will take place at the end of December, based on verification indicators for each technology. Selected technologies will be introduced as pilot programs for Han River bridge safety inspections and safety diagnosis services as early as next year.
