FAQ

What work fits NAICS 238120?
  • Erecting structural steel frames, including bolting and field welding, with erection sequencing and crane-lift plans.
  • Installing precast concrete panels, setting anchors to tolerance, and providing panel alignment and finishing at the structure.
  • Supply-and-erect structural steel packages matched to approved drawings, with delivery coordination, mill certificates, and connection fit-up verification.
  • Field welding, non-destructive testing, and documentation of weld inspection records and anchor bolt tolerance verification during erection.
When is NAICS 238120 a weak fit?
  • Reinforcing steel (rebar) placement and cast-in-place concrete work where the contract focuses on concrete placement and consolidation rather than precast panel erection or structural steel assembly.
  • Miscellaneous steel fabricators producing ornamental, light-gauge, or nonstructural metalwork that lacks structural-grade fabrication, engineered connections, and field erection responsibilities.
  • General concrete contractors performing formwork and cast-in-place pours without provision of prefabricated precast panels or structural steel erection and associated rigging plans.
What solicitation language points to NAICS 238120?
  • Scope requires stamped connection calculations, approved erection plans, welding procedure specifications, and NDT reports for structural connections.
  • Labor categories identify certified structural steel erectors, certified welders, rigging supervisors, and crane signal persons.
  • Performance language includes anchor bolt tolerance tables, panel alignment tolerances, and inspection hold-point procedures with required documentation.
