Thomas & Marker Construction: 1.2 TCR = 40% of Commercial building construction BLS 2.9 · 4y Form 300A (see methodology below)

Thomas & Marker Construction safety composite

Thomas & Marker Construction scores strongest on total case rate (tcr) (safer than 73% of same-industry peers) and weakest on dart rate (safer than 33%), 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).
