Main Office: 7.8 TCR = 205% of Housing, single-family, construction general contractors BLS 3.8 · 7y Form 300A (see methodology below)

Main Office safety composite

Main Office scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 23%), 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).
