The verdict

Marpac Construction LLC: 3.7 TCR = 97% of Construction BLS 3.8 · 2y Form 300A (see methodology below)

Marpac Construction LLC safety composite

Marpac Construction LLC scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 38%), 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).
