ECS: Element condition score, 1 best to 5 worst.
ECI: Element condition index: the score reduced for less important elements.

Condition PI after the CSS Bridges Group guidance for highway structures (2007). Its bands (very good from 90, good 80, fair 65, poor 40) are stricter than the platform grades. Element value shares, intervention thresholds and repair costs are illustrative assumptions.
