Tri Tech Construction: 3.2 TCR = 115% of Mechanical contractors BLS 2.8 · 5y Form 300A (see methodology below)

Tri Tech Construction safety composite

Tri Tech Construction scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 51%), 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).

Tri Tech Construction has fewer employees than the Mechanical contractors median and a lower injury rate than the industry's median TCR of 3.3. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
