NAICS 238120 · United States · 2022 edition
This industry comprises establishments primarily engaged in (1) erecting and assembling structural parts made from steel or precast concrete (e.g., steel beams, structural steel components, and similar products of precast concrete) and/or (2) assembling and installing other steel construction products (e.g., steel rods, bars, rebar, mesh, and cages) to reinforce poured-in-place concrete. The work performed may include new work, additions, alterations, maintenance, and repairs.
Start the review with workers' compensation.
For Structural Steel and Precast Concrete Contractors, the saved research highlights workers' compensation, general liability, completed operations. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What is the typical height range of projects — single-story, multi-story, high-rise, or infrastructure like bridges?
- Does the contractor own cranes, or are lifts performed with rented cranes and operators?
- What is the split of work between structural steel erection, rebar/reinforcing, and precast concrete installation?
- Does the operation include any design-assist or connection design responsibility, or is all work performed to engineer-supplied drawings?
- Are written subcontract agreements with certificate of insurance requirements in place for any lower-tier subcontractors used?
- What is the experience modification factor and recent workers comp loss history?
- Are any projects on marine, waterfront, or navigable waterway structures?
- What types of GC or project owner insurance requirements — minimum limits, additional insured forms, completed operations tails — are typically demanded by contract?

Structural steel and precast concrete contractors erect steel frameworks, beams, columns, and structural components on commercial, industrial, and infrastructure projects — typically as specialty subcontractors to a general contractor. Work may include placing and tying rebar and reinforcing mesh before concrete pours, installing precast or prestressed concrete panels and slabs, and assembling structural steel frames using cranes and rigging. Operations routinely take place at significant heights and involve heavy loads, crane coordination, and multi-trade job site interaction.
