Michigan Structure Inspection Manual
MDOT has completed the first version of the Michigan Structure Inspection Manual (MiSIM). The manual has been developed to provide bridge safety inspectors and bridge owners with guidance for meeting the requirements of the National Bridge Inspection Standards (NBIS) and Michigan's Bridge Inspection Program policies and procedures. This manual provides guidance for inspecting structures meeting the NBIS definition of a bridge and for non-NBI structures with span lengths less than 20 feet, pedestrian, and railroad structures.
The purpose of the MiSIM is to reinforce the policies and procedures of MDOT, ensure statewide consistency with reference to completing and documenting the condition of structures, and to improve FHWA compliance. The contents will be periodically updated to strengthen the program.
