Massman Construction Company: 1.1 TCR = 39% of Bridge approach construction BLS 2.8 · 2y Form 300A (see methodology below)

Massman Construction Company safety composite

Massman Construction Company scores strongest on total case rate (tcr) (safer than 82% of same-industry peers) and weakest on dart rate (safer than 44%), 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).
