Industry benchmark
BLS rates reflect industry-wide averages. Self-reported figures come from OSHA’s Injury Tracking Application; absence of self-reported data does not necessarily indicate non-compliance — many establishments fall below the ITA reporting threshold.
Inspection breakdown
Complaint- and accident-triggered inspections are stronger risk signals than routine planned inspections.

Company-level in CO — for SEMA Construction, not this location alone

Negligence rating is MSHA’s operator-culpability assessment (none, low, moderate, high, or reckless disregard). Proposed = assessed at issuance; Paid = post-settlement / appeal. 1 citation · 1 contractor · $125 proposed / $125 paid.

Establishments are matched across agencies using normalized employer name, state, and ZIP code. This establishment resolves to the parent rollup SEMA Construction, which operates 51 establishments in our dataset.
OSHA citations typically appear 3–8 months after the inspection, so very recent enforcement actions may not yet be reflected. Profiles may be incomplete if the establishment operates under multiple legal names or files under variations our entity-matching rules don’t yet cover.
