Diamond Services Company: 0.4 TCR = 16% of Excavating, earthmoving, or land clearing contractors BLS 2.8 · 2y Form 300A (see methodology below)

Diamond Services Company safety composite

Diamond Services Company scores strongest on total case rate (tcr) (safer than 96% of same-industry peers) and weakest on fatalities (safer than 52%), 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).
