Staab Construction Corporation safety composite

Staab Construction Corporation scores strongest on fatalities (safer than 52% of same-industry peers) and weakest on total case rate (tcr) (safer than 4%), 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).
