  • [Core] Verify vertical and horizontal alignment of structural steel members, using plumb bobs, laser equipment, transits, or levels.
  • [Core] Connect columns, beams, and girders with bolts, following blueprints and instructions from supervisors.
  • [Core] Bolt aligned structural steel members in position for permanent riveting, bolting, or welding into place.
  • [Core] Fabricate metal parts, such as steel frames, columns, beams, or girders, according to blueprints or instructions from supervisors.
  • [Core] Pull, push, or pry structural steel members into approximate positions for bolting into place.
  • [Core] Cut, bend, or weld steel pieces, using metal shears, torches, or welding equipment.
  • [Core] Fasten structural steel members to hoist cables, using chains, cables, or rope.
  • [Core] Assemble hoisting equipment or rigging, such as cables, pulleys, or hooks, to move heavy equipment or materials.
