Does "Subpart R - Steel Erection" Apply to You?

Subpart R provides the standards for steel erection activities involved in the construction, alteration, and/or repair of single and multi-story buildings, bridges, and other structures where steel erection occurs. The scope applies to employers engaged in steel erection unless otherwise specified. It does not cover electrical transmission towers, communication and broadcast towers, or tanks.

Steel erection activities include hoisting, laying out, placing, connecting, welding, burning, guying, bracing, bolting, plumbing and rigging structural steel, steel joists and metal buildings; installing metal decking, curtain walls, window walls, siding systems, miscellaneous metals, ornamental iron and similar materials; and moving point-to-point while performing these activities.

The following activities are covered by this subpart when they occur during and are a part of steel erection activities: rigging, hoisting, laying out, placing, connecting, guying, bracing, dismantling, burning, welding, bolting, grinding, sealing, caulking, and all related activities for construction, alteration and/or repair of materials and assemblies such as structural steel; ferrous metals and alloys; non-ferrous metals and alloys; glass; plastics and synthetic composite materials; structural metal framing and related bracing and assemblies; anchoring devices; structural cabling; cable stays; permanent and temporary bents and towers; falsework for temporary supports of permanent steel members; stone and other non-precast concrete architectural materials mounted on steel frames; safety systems for steel erection; steel and metal joists; metal decking and raceway systems and accessories; metal roofing and accessories; metal siding; bridge flooring; cold formed steel framing; elevator beams; grillage; shelf racks; multi-purpose supports; crane rails and accessories; miscellaneous, architectural and ornamental metals and metal work; ladders; railings; handrails; fences and gates; gratings; trench covers; floor plates; castings; sheet metal fabrications; metal panels and panel wall systems; louvers; column covers; enclosures and pockets; stairs; perforated metals; ornamental iron work, expansion control including bridge expansion joint assemblies; slide bearings; hydraulic structures; fascias; soffit panels; penthouse enclosures; skylights; joint fillers; gaskets; sealants and seals; doors; windows; hardware; detention/security equipment and doors, windows and hardware; conveying systems; building specialties; building equipment; machinery and plant equipment, furnishings and special construction.

Are your employees engaged in steel erection activities as identified above? If yes, then subpart R applies to you. This subpart also provides definitions to terms used in the standards. The subpart provides the standards for site layout, site-specific erection plan and construction sequence, hoisting and rigging (i.e., working under loads, qualified riggers, multiple lifts), structural steel assembly (i.e., walking/working surfaces, tripping hazards, plumbing up, metal decking, holes and opening), column anchorage, beams and columns (i.e., bracing, splices), open-web steel joists (i.e., erection, attachment, field-bolted, bridging, loads), systems-engineered metal buildings, falling object protection, fall protection (i.e., safety cables, controlled decking zones, criteria, custody of fall protection) and training.

In addition, you need to comply with the state specific standard on steel erection. The North Carolina state specific standard expanded and clarified the scope and added more requirements pertaining to tripping hazards to paragraph (c)(1)
