Types of Carpenters There are two basic types of carpenters: rough carpenters and finish carpenters. Rough carpenters, who are also known as structural carpenters, construct the inner frameworks of building and temporary structures (scaffolds, forms in which concrete is poured into, bridge or sewer supports, etc.) by following blueprints or oral instruc- tions from foremen and construction superintendents. They help build or repair homes, apartment buildings, factories, bridges, roads, railroads, airports, or any other type of structure imaginable. It is extremely important that their work is of the utmost quality. Otherwise, buildings under construction may collapse or may not be built up to code. Typical duties of rough carpenters include: • Studying blueprints, sketches, or building plans, or following supervisor instruc- tions, to prepare the project layout and determine dimensions and the types of lumber, materials, supplies, and tools that are required • Using hand tools, power tools, and machines to shape or cut wood, plastic, and other materials • Constructing forms or chutes for pouring concrete • Erecting scaffolding or ladders for assembling structures • Constructing and erecting building frameworks, including floors, walls, and door- frames • Installing components and fixtures such as windows, doors, and molding • Installing insulation or drywall • Installing roof joists, trusses, and rafters • Laying roofs with shingles and plywood • Laying wood floors and stairs • Installing weather-stripping, insulation, and caulking • Installing drywall • Removing damaged or defective components or sections of structures and repairing or replacing them • Checking completed work with squares or levels • Performing minor welding, plumbing, electrical, or concrete mixing work.
