Ironworkers (Reinforcing) cut, bend, lay out, place and weld reinforcing steel rods, and also weld wire fabric and composite materials in a wide variety of structures such as buildings, highways, bridges, stadiums and towers. They also place and stress various post-tensioning systems in structures such as parking garages, bridges and stadiums where longer unsupported spans are required.
After placing post-tensioning systems, they stress the tendons to predetermined specifications using hydraulic jacks and pumps. They unload fabricated or bar materials and place the material for hoisting as needed. They can be involved in cutting and bending material according to design specifications and drawings, and they may pre-assemble reinforcing material by laying the material out and connecting sub-assemblies on the ground prior to final placement. They also organize the hoisting of the components by connecting the cables and slings to the components and directing crane operators, and they position, align and secure components according to drawings, using a variety of methods.
