Exterior Designs: 6.5 TCR = 232% of Granite, exterior, contractors BLS 2.8 · 3y Form 300A (see methodology below)

Exterior Designs safety composite

Exterior Designs scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 26%), 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).
