About this page

This page announces a call for new technologies to reduce road collapse damage by the Ministry of Land, Infrastructure, Transport and Tourism. Underground utilities such as sewage systems cause road collapses, necessitating technologies that prevent brittle fractures in subsurface cavities and detect cavities or collapse risk areas. The recruitment period runs from March 23 to May 22, 2026, for two technology categories. Detailed application guidelines are available on designated websites. Inquiries should be directed to the National Institute for Land and Infrastructure Management and the Advanced Construction Technology Center.
