Benchmarked against the Bureau of Labor Statistics industry average of 4.5 for Commuter rail systems (except mixed mode), ACI-Herzog, Joint Venture's workforce experiences 44% of the typical injury burden. This ratio matters because TCR already normalizes for hours worked — a 200,000-hour exposure base equals roughly 100 full-time workers — so establishments with very different headcounts can be compared directly. A TCR below the benchmark signals that controls, training, or automation may be outperforming peers.
Multi-year trend analysis is the single most reliable signal here: a one-year spike could reflect a single severe event, whereas sustained elevation across 4 reporting cycles points to systemic hazard exposure. Readers evaluating ACI-Herzog, Joint Venture as an employer, contractor, investment, or regulatory target should examine the yearly DART rate (days away, restricted, or transferred), the fatality count of 0, and any year-over-year deterioration shown in the table below.

DART Rate — Transparent Calculation (2019)
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
7 DART incidents × 200,000 ÷ 636,667 hours worked = 2.20 DART
Methodology: 29 CFR 1904 — OSHA Form 300A recordkeeping
