  • Determine project requirements, such as scope, assembly sequences, or required methods or materials, using blueprints, drawings, or written or verbal instructions.
  • Lay out, measure, and mark dimensions and reference lines on material, such as roofing panels, using calculators, scribes, dividers, squares, or rulers.
  • Fasten seams or joints together with welds, bolts, cement, rivets, solder, caulks, metal drive clips, or bonds to assemble components into products or to repair sheet metal items.
  • Trim, file, grind, deburr, buff, or smooth surfaces, seams, or joints of assembled parts, using hand tools or portable power tools.
  • Fabricate ducts for high efficiency heating, ventilating, and air conditioning (HVAC) systems to maximize efficiency of systems.
  • Select gauges or types of sheet metal or nonmetallic material, according to product specifications.
  • Finish parts, using hacksaws or hand, rotary, or squaring shears.
  • Shape metal material over anvils, blocks, or other forms, using hand tools.
  • Fabricate or alter parts at construction sites, using shears, hammers, punches, or drills.
  • Transport prefabricated parts to construction sites for assembly and installation.
  • Install assemblies, such as flashing, pipes, tubes, heating and air conditioning ducts, furnace casings, rain gutters, or downspouts in supportive frameworks.
  • Hire, train, or supervise new employees or apprentices.
  • Maintain equipment, making repairs or modifications when necessary.
  • Develop or lay out patterns, using computerized metalworking equipment.
  • Maneuver completed roofing units into position for installation.
  • Inspect individual parts, assemblies, or installations, using measuring instruments, such as calipers, scales, or micrometers.
  • Verify that heating, ventilating, and air conditioning (HVAC) systems are designed, installed, and calibrated in accordance with green certification standards, such as those of Leadership in Energy and Environmental Design (LEED).
  • Secure metal roof panels in place by interlocking and fastening grooved panel edges.
  • Perform building commissioning activities by completing mechanical inspections of a building's water, lighting, or heating, ventilating, and air conditioning (HVAC) systems.
  • Fasten roof panel edges or machine-made moldings to structures by nailing or welding.
  • Perform sheet metal work necessary for solar panel installations.
  • Install green architectural sheet metal components, such as cool roofs or hot or cold walls.
  • Construct components for high-performance wind turbine systems.

Interests

  • Realistic - Realistic occupations frequently involve work activities that include practical, hands-on problems and solutions. They often deal with plants, animals, and real-world materials like wood, tools, and machinery. Many of the occupations require working outside, and do not involve a lot of paperwork or working closely with others.

Education, training, experience
