Power and Communication Line and Related Structures Construction
NAICS 237130 · United States · 2022 edition
This industry comprises establishments primarily engaged in the construction of power lines and towers, power plants, and radio, television, and telecommunications transmitting/receiving towers. 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 power and communication line and related structures construction. All structures (including buildings) that are integral parts of power and communication networks (e.g., transmitting towers, substations, and power plants) are included.

Contractors in this class build, reconstruct, and repair power transmission and distribution lines, communication towers, substations, underground utility cables, and related structures. Day-to-day work typically involves aerial work from bucket trucks or climbing, trenching and directional boring for underground cable, tower steel erection, and energized or de-energized line work — often performed in remote or right-of-way environments under contracts with utilities, telecom carriers, or government entities.
Questions to investigate
- Does the contractor perform any energized or 'hot' line work, and if so, what voltage levels?
- Is tower climbing a significant portion of the work, and what is the documented safety and rescue program?
- What is the breakdown of work between overhead line, underground cable, tower construction, substation work, and alternative energy structures?
- Does the contractor participate in any wrap-up, OCIP, or CCIP programs on project sites, and how are those periods handled on their own policies?
