Building Maintenance (Mechanical/Electrical): 8.7 TCR = 194% of Bridge, tunnel, and highway operations BLS 4.5 · 8y Form 300A (see methodology below)

Building Maintenance (Mechanical/Electrical) safety composite

Building Maintenance (Mechanical/Electrical) scores strongest on dart rate (safer than 82% of same-industry peers) and weakest on total case rate (tcr) (safer than 18%), 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).
