ARB Structures: 0.7 TCR = 25% of Chimney, concrete, construction BLS 2.8 · 3y Form 300A (see methodology below)

ARB Structures safety composite

ARB Structures scores strongest on total case rate (tcr) (safer than 94% of same-industry peers) and weakest on fatalities (safer than 51%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
