Carpenters construct and repair building frameworks and structures--such as stairways, doorframes, partitions, and rafters--made from wood and other materials. They also may install kitchen cabinets, siding, and drywall.
Carpenters typically do the following:
Carpenters are one of the most versatile construction occupations, with workers usually doing a variety of tasks. For example, some carpenters insulate office buildings; others install drywall or kitchen cabinets in homes. Those who help construct large buildings or bridges often make the wooden concrete forms for cement footings or pillars. Some carpenters build braces and scaffolding for buildings.
Carpenters use many different hand and power tools to cut and shape wood, plastic, fiberglass, or drywall. They commonly use handtools, including squares, levels, and chisels, as well as many power tools, such as sanders, circular saws, and nail guns. Carpenters put materials together with nails, screws, staples, and adhesives, and do a final check of their work to ensure accuracy. They use a tape measure on every project because proper measuring increases productivity, reduces waste, and ensures that the pieces being cut are the proper size.
The following are types of carpenters:
Residential carpenters typically specialize in new-home, townhome, and condominium building and remodeling. As part of a single job, they might build and set forms for footings, walls and slabs, and frame and finish exterior walls, roofs, and decks. They frame interior walls, build stairs, and install drywall, crown molding, doors, and kitchen cabinets. Highly-skilled carpenters may also tile floors and lay wood floors and carpet. Fully-trained construction carpenters are easily able to switch from new-home building to remodeling.
Commercial carpenters typically remodel and help build commercial office buildings, hospitals, hotels, schools, and shopping malls. Some specialize in working with light gauge and load-bearing steel framing for interior partitions, exterior framing, and curtain wall construction. Others specialize in working with concrete forming systems and finishing interior and exterior walls, partitions, and ceilings. Highly skilled carpenters can usually do many of the same tasks as residential carpenters.
Industrial carpenters typically work in civil and industrial settings where they put up scaffolding and build and set forms for pouring concrete. Some industrial carpenters build tunnel bracing or partitions in underground passageways and mines to control the circulation of air to worksites. Others build concrete forms for tunnels, bridges, dams, power plants, or sewer construction projects.
Janitors and building cleaners keep many types of buildings clean, orderly, and in good condition.
Janitors and building cleaners typically do the following:
Janitors and building cleaning workers keep office buildings, schools, hospitals, retail stores, hotels, and other places clean, sanitary, and in good condition. Some do only cleaning, while others have a wide range of duties.
In addition to keeping the inside of buildings clean and orderly, some janitors and building cleaners work outdoors, mowing lawns, sweeping walkways, or shoveling snow. Some janitors also monitor the heating and cooling system, ensuring that it functions properly.
Janitors and building cleaners use many tools and equipment. Simple cleaning tools may include mops, brooms, rakes, and shovels. Other tools may include snowblowers and floor buffers.
Some janitors may be responsible for repairing small problems with electricity or plumbing, such as leaky faucets.
Construction laborers and helpers do many basic tasks that require physical labor on construction sites.
Construction laborers and helpers typically do the following:
Construction laborers and helpers work on almost all construction sites, doing a wide range of tasks from the very easy to the extremely difficult and hazardous. Although many of the tasks they do require some training and experience, most jobs usually require little skill and can be learned quickly.
The following are occupational specialties:
Construction laborers do a variety of construction-related activities during all phases of construction. Although most laborers are generalists--such as those who install barricades, cones, and markers to control traffic patterns--many others specialize. For example, those who operate the machines and equipment that lay concrete or asphalt on roads are more likely to specialize in those areas.
Most construction laborers work in the following areas:
Construction laborers use a variety of tools and equipment. Some tools are simple, such as brooms and shovels; other equipment is more sophisticated, such as pavement breakers, jackhammers, earth tampers, and surveying equipment.
With special training, laborers may help transport and use explosives or run hydraulic boring machines to dig out tunnels. They may learn to use laser beam equipment to place pipes and use computers to control robotic pipe cutters. They may become certified to remove asbestos, lead, or chemicals.
Helpers assist construction craftworkers, such as electricians and carpenters, with a variety of basic tasks. They may carry tools and materials or help set up equipment. For example, many helpers work with cement masons to move and set forms. Many other helpers assist with taking apart equipment, cleaning up sites, and disposing of waste, as well as helping with any other needs of craftworkers.
Many construction trades have helpers who assist craftworkers. The following are examples of trades that have associated helpers:
Maids and housekeeping cleaners perform general cleaning tasks, including making beds and vacuuming halls, in private homes and commercial establishments.
Maids and housekeeping cleaners typically do the following:
Maids and housekeeping cleaners do light cleaning tasks in homes and commercial establishments, such as hotels, restaurants, hospitals, and nursing homes.
In addition to keeping these places clean and neat, maids who work in private homes also may prepare meals, polish silver, and clean ovens, refrigerators, and sometimes windows. Some also shop for groceries, pick up and drop off dry cleaning, and do other errands.
Those who work in hotels, hospitals, and other commercial establishments are responsible for cleaning and maintaining the premises. They may also share other duties. For example, housekeeping cleaners in hotels may deliver ironing boards, cribs, and rollaway beds to guests' rooms. In hospitals, workers may have to wash bed frames and disinfect and sanitize equipment with germicides.
Upholsterers make, replace, and repair coverings on furniture and in vehicles.
Upholsterers typically do the following:
Upholsterers put on covering and cushions to create new furniture and update old furniture and vehicle interiors. Although some upholsterers specialize in either working with old furniture or creating new furniture, most do both.
Upholsterers need to stay current with trends in furniture design and styles. They help choose fabrics that meet their customer's lifestyle, preferences, and needs. For example, upholsterers may help a client who has young children choose a long-lasting and durable fabric for a family room sofa that matches other furniture.
Sometimes they have to choose fabrics that meet building codes--such as being fire resistant--or fabrics that reflect the style of the building. They also may work with interior designers and architects who need furniture for a new building. For more information, see the profiles on interior designers and architects.
Upholsterers may specialize in working on cars and other vehicles. These workers create and replace upholstery for the interiors of cars and other vehicles. They upholster seats, carpet floors, and cover door panels. To replace interiors with another fabric or other material, such as leather, these workers first remove the seats from the vehicle before replacing the upholstery.
Some upholsterers own their business. In these cases, they may do management and administrative tasks, such as managing the finances of their business and taking orders.
