SCMI Ratings and Inspection Details

Every 6 years, Network Rail carry out detailed inspections on all their structures, which in most cases includes the calculation of an SCMI (or Structures Condition Marking Index). An SCMI score is a number between 0 and 100 and is used to grade the condition of a structure or how close it is to life-expiration. These figures are derived from a 2015 dataset and may not represent the present structure condition.

SCMI Score: 68- - -Bridge Condition Grade: 2- - -Inspection Date: 02/2015 As a (very) rough guide, a score below 40 is considered in poor condition, with a score above 80 in excellent condition.
The chart below shows SCMI scores and their equivalent Bridge Condition Grades (BCG).
