NAICS 237310 · United States · 2022 edition
This industry comprises establishments primarily engaged in the construction of highways (including elevated), streets, roads, airport runways, public sidewalks, or bridges. The work performed may include new work, reconstruction, rehabilitation, and repairs. Specialty trade contractors are included in this industry if they are engaged in activities primarily related to highway, street, and bridge construction (e.g., installing guardrails on highways).
Start the review with third-party auto and property damage on active roadways.
For Highway, Street, and Bridge Construction, the saved research highlights third-party auto and property damage on active roadways, employee injury severity, equipment.

- What is the owned equipment schedule — types, ages, and estimated replacement values?
- Are any design-build or design-assist responsibilities included in any current or anticipated contracts?
- Does any work take place near active railroad lines, navigable waterways, or environmentally sensitive areas?
- What is the ratio of employee labor to subcontracted labor, and are certificates of insurance collected for all subs?
- What is the current experience modification factor and the prior three years' loss history?
- Are there active surety relationships, and what is the bonding program capacity relative to anticipated contract volume?
