||Sheet Metal Workers
- Fabricate ducts for high efficiency heating, ventilating, and air conditioning (HVAC) systems to maximize efficiency of systems.
- 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.
- Perform sheet metal work necessary for solar panel installations.
||Drywall and Ceiling Tile Installers
- Cut fixture or border tiles to size, using keyhole saws, and insert them into surrounding frameworks.
- Mount tile, using adhesives, or by nailing, screwing, stapling, or wire-tying lath directly to structural frameworks.
- Nail channels or wood furring strips to surfaces to provide mounting for tile.
- Apply cement to backs of tiles and press tiles into place, aligning them with layout marks or joints of previously laid tile.
- Shape or fabricate parts, such as stacks, uptakes, or chutes, to adapt pressure vessels, heat exchangers, or piping to premises, using heavy-metalworking machines such as brakes, rolls, or drill presses.
- Shape seams, joints, or irregular edges of pressure vessel sections or structural parts to attain specified fit of parts, using cutting torches, hammers, files, or metalworking machines.
- Straighten or reshape bent pressure vessel plates or structure parts, using hammers, jacks, or torches.
- Install refractory bricks or other heat-resistant materials in fireboxes of pressure vessels.
||Tile and Marble Setters
- Lay and set mosaic tiles to create decorative wall, mural, and floor designs.
- Finish and dress the joints and wipe excess grout from between tiles, using damp sponge.
- Cut, surface, polish, and install marble and granite or install pre-cast terrazzo, granite or marble units.
- Build underbeds and install anchor bolts, wires, and brackets.
||Brickmasons and Blockmasons
- Construct corners by fastening in plumb position a corner pole or building a corner pyramid of bricks, and filling in between the corners using a line from corner to corner to guide each course, or layer, of brick.
- Fasten or fuse brick or other building material to structure with wire clamps, anchor holes, torch, or cement.
- Lay and align bricks, blocks, or tiles to build or repair structures or high temperature equipment, such as cupola, kilns, ovens, or furnaces.
