The Bridge Condition Index (BCI) is calculated automatically in BridgeStation based upon:

Inspection Proforma and,
Corrected Defects

Only certain inspections are included in the BCI calculation. Inspection type and the inspection's signoff status may mean element conditions are not included in the BCI calculation. A typical configuration is shown below;

* superficial inspections are excluded from the BCI calculations

** your authority's exact configuration may differ from the above, contact BridgeStation Support for more details.

BridgeStation will report the BCI Average and Critical for each structure. For more information see here: Condition (BCI) - Average and Critical Calculations

The Structure Summary displays the structure's latest condition (BCI Average and BCI Critical) along with the Last Inspection date.

The BCI Average and BCI Critical shown will normally match the results from the Last Inspection. However, this is not always the case, corrected defects or archived elements may affect the results.
