Corti Construction: 2.5 TCR = 87% of Addition, alteration and renovation general contractors, commercial and institutional building BLS 2.9 · 3y Form 300A (see methodology below)

Corti Construction safety composite

Corti Construction scores strongest on dart rate (safer than 73% of same-industry peers) and weakest on total case rate (tcr) (safer than 46%), 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).
