An apartment complex in the southern city of Busan experienced a total blackout when a forklift mangled an underground power line at a subway construction site last month. Thousands were left in the mid summer's heat wave without electricity.
To prevent such accidents, Busan has launched a project to draw a vast integrated 3D map database of underground space.
"Through this project, the 3D map of Busan's underground space will be developed and when it's done, we will be able to prevent safety accidents very effectively," the Busan city government said in a statement on Tuesday.
The 1.38 billion won (12.16 million US dollars) project will cover 15 districts in Busan by June next year with information on a web of water, power, gas pipelines as well as the city's sewage system and other structures including subway lines and parking lots.
City officials hope the 3D underground map would effectively predict and prevent the creation of sinkholes, a frequent threat to public safety.
