We carry out check of bridge every five years and, in Kitami-shi, diagnose soundness based on "Kitami-shi bridge extension of life repair plan".
About bridge which carried out check, we will announce result.
Please refer to the following for judgment division.
I: Soundly (state that trouble does not produce for function of structure.)
II: Preventive maintenance stage (trouble does not occur for function of structure, but it is in a desirable state to take measures from the viewpoint of preventive maintenance.)
III: Early measures stage (state that trouble may occur for function of structure and should take early measures for.)
IV: Emergency measures stage (state that possibility trouble occurs for function of structure or to produce is remarkably high and should urgently take measures for.)
