The verdict

Landmark Construction runs at 33% of its industry's injury rate - far safer than the typical Trenching (except underwater) workplace, earning a grade A.

Landmark Construction: 0.9 TCR = 33% of Trenching (except underwater) BLS 2.8 · 3y Form 300A (see methodology below)

Landmark Construction safety composite

Landmark Construction scores strongest on total case rate (tcr) (safer than 86% of same-industry peers) and weakest on dart rate (safer than 50%), 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).

Grade A

More dangerous than peersSafer than peers

Narrower to South Carolina alone (the establishments it most directly competes with for workers and contracts): ranked #7 safest of 26 Trenching (except underwater) employers in South Carolina.

Landmark Construction (269 employees, TCR 0.9) among 29 same-industry peers, split at the industry median of 51 employees and a TCR of 2.5

Landmark Construction has more employees than the Trenching (except underwater) median and a lower injury rate than the industry's median TCR of 2.5. 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.
