• Fasten structural-steel members to hoist cables, using chains, cables, or rope.
• Force structural-steel members into final positions, using turnbuckles, crowbars, jacks, and hand tools.
• Hoist steel beams, girders, and columns into place, using cranes, or signal hoisting equipment operators to lift and position structural-steel members.
• Hold rivets while riveters use air-hammers to form heads on rivets.
• Insert sealing strips, wiring, insulating material, ladders, flanges, gauges, and valves, depending on types of structures being assembled.
• Place blocks under reinforcing bars used to reinforce floors.
• Pull, push, or pry structural-steel members into approximate positions for bolting into place.
• Read specifications and blueprints to determine the locations, quantities, and sizes of materials required.
• Ride on girders or other structural-steel members to position them, or use rope to guide them into position.
• Unload and position prefabricated steel units for hoisting as needed.
• Verify vertical and horizontal alignment of structural-steel members, using plumb bobs, laser equipment, transits, and/or levels.
