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: 61- - -Bridge Condition Grade: 2- - -Inspection Date: 12/2013
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).
| SCMI: 80+BCG: 1 | SCMI: 60 - 79BCG: 2 | SCMI: 40 - 59BCG: 3 | SCMI: 20 - 39BCG: 4 | SCMI: -19BCG: 5 |
