Irby Construction: 1.6 TCR = 59% of Transmission and distribution line construction BLS 2.8 · 6y Form 300A (see methodology below)

Irby Construction safety composite

Irby Construction scores strongest on total case rate (tcr) (safer than 56% of same-industry peers) and weakest on fatalities (safer than 3%), 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).
