Build rough wooden structures, such as concrete forms, scaffolds, tunnel, bridge, or sewer supports, billboard signs, and temporary frame shelters, according to sketches, blueprints, or oral instructions.

Study blueprints and diagrams to determine dimensions of structure or form to be constructed. Measure materials or distances, using square, measuring tape, or rule to lay out work. Cut or saw boards, timbers, or plywood to required size, using handsaw, power saw, or woodworking machine. Assemble and fasten material together to construct wood or metal framework of structure, using bolts, nails, or screws. Anchor and brace forms and other structures in place, using nails, bolts, anchor rods, steel cables, planks, wedges, and timbers. Mark cutting lines on materials, using pencil and scriber. Erect forms, framework, scaffolds, hoists, roof supports, or chutes, using hand tools, plumb rule, and level. Install rough door and window frames, subflooring, fixtures, or temporary supports in structures undergoing construction or repair. Examine structural timbers and supports to detect decay, and replace timbers as required, using hand tools, nuts, and bolts. Bore boltholes in timber, masonry or concrete walls, using power drill. Fabricate parts, using woodworking and metalworking machines. Dig or direct digging of post holes and set poles to support structures. Build sleds from logs and timbers for use in hauling camp buildings and machinery through wooded areas. Build chutes for pouring concrete.
