Bridges and tunnels in mountainous areas that are difficult to access will be inspected reliably by a team familiar with the local conditions.
Infrastructure located in hard-to-access areas, such as forest roads, agricultural roads, and mountain tunnels, can make inspections difficult. However, overlooking the aging or damage of such facilities poses risks directly related to traffic safety. This service addresses inspections of infrastructure in mountainous and hilly areas that are difficult to access. We will establish an inspection system tailored to the local conditions and carry out reliable close visual inspections and documentation.
