The verdict

Public Works runs at 163% of its industry's injury rate - more dangerous than the typical Construction management, highway, road, street and bridge workplace, earning a grade D.

Public Works: 4.5 TCR = 163% of Construction management, highway, road, street and bridge BLS 2.8 · 2y Form 300A (see methodology below)

Public Works safety composite

Public Works scores strongest on dart rate (safer than 81% of same-industry peers) and weakest on total case rate (tcr) (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).
