Home Construction Office: 0.8 TCR = 29% of Sewer main, pipe and connection, construction BLS 2.8 · 6y Form 300A (see methodology below)

Home Construction Office safety composite

Home Construction Office scores strongest on total case rate (tcr) (safer than 91% of same-industry peers) and weakest on dart rate (safer than 14%), 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).
