Diamond Steel Construction safety composite

Diamond Steel Construction scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on fatalities (safer than 53%), blended into one 0-100 breakdown against same-industry peers.

This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
