Which code does this activity belong in?

Establishments in this industry erect and assemble prefabricated structural components made of steel or precast concrete, or install reinforcing materials like rebar and mesh into poured-in-place concrete at construction sites. The key distinction from Poured Concrete Foundation and Structure Contractors is that this code covers work with precast concrete products and reinforcing steel, while Poured Concrete Foundation and Structure Contractors handles the pouring and finishing of concrete itself. Framing Contractors, by contrast, primarily work with wood or metal framing systems rather than structural steel or precast concrete assembly.
