Construction managers plan, coordinate, budget, and supervise construction projects from early development to completion.

Construction managers typically do the following:

• Prepare and negotiate cost estimates, budgets, and work timetables
• Select appropriate construction methods and strategies
• Interpret and explain contracts and technical information to workers and other professionals
• Report on work progress and budget matters to clients
• Collaborate with architects, engineers, and other construction and building specialists
• Instruct and supervise construction personnel and activities onsite
• Respond to work delays and other problems and emergencies
• Select, hire, and instruct laborers and subcontractors  
• Comply with legal requirements, building and safety codes, and other regulations

Construction managers, often called general contractors or project managers, coordinate and supervise a wide variety of projects, including the building of all types of residential, commercial, and industrial structures, roads, bridges, powerplants, schools, and hospitals. They oversee specialized contractors and other personnel. Construction managers schedule and coordinate all design and construction processes to ensure a productive and safe work environment. They also make sure jobs are completed on time and on budget with the right amount of tools, equipment, and materials. Many managers also are responsible for obtaining necessary permits and licenses. They are often responsible for multiple projects at a time.

Construction managers work closely with other building specialists, such as architects, engineers, and a variety of trade workers, such as stonemasons, electricians, and carpenters. Projects may require specialists in everything from structural metalworking and painting, to landscaping, building roads, installing carpets, and excavating sites. Depending on the project, construction managers also may interact with lawyers and local government officials. For example, when working on city-owned property or municipal buildings, managers sometimes confer with city council members to ensure that all regulations are met.

For projects too large to be managed by one person, such as office buildings and industrial complexes, a construction manager would only be in charge of one part of the project. Each construction manager would oversee a specific construction phase and choose subcontractors to complete it. Construction managers may need to collaborate and coordinate with other construction managers who are responsible for different aspects of the project.

To maximize efficiency and productivity, construction managers often use specialized cost-estimating and planning software to effectively budget the time and money required to complete specific projects. Many managers also use software to determine the best way to get materials to the building site. For more information, see the profile on cost estimators.

Carpet installers lay carpet in homes, offices, restaurants, and many other types of buildings. 

Carpet installers typically do the following:

• Remove old carpet or flooring to prepare surfaces for laying new carpet
• Inspect the condition of the surface to be covered
• Fix any problems that could show through the carpet or cause uneven wear
• Measure the area to be carpeted
• Plan the layout of carpeting to get the best appearance and least wear
• Install a padded cushion underneath the carpet
• Roll out, measure, mark, and cut the carpet
• Fit the carpet so that it lays evenly and snugly
• Tack, glue, or staple carpeting to hold it in place
• Finish the edges so that the carpet looks neat

Carpet installers lay carpet in many types of new and old buildings, including homes, offices, restaurants, and museums. Although installing carpet in newly constructed buildings requires minimal preparation, those who replace existing carpet must first remove old flooring, including any padding, glue, tacks, or staples. In some cases, carpet installers lay carpet over existing tile or hardwood.

Carpet installers work with special tools, including a "knee kicker" to position the carpet and a power stretcher to pull the carpet snugly against walls. When they have to join seams of carpet (for example, in large rooms), they use special heat-activated tape. In commercial installations, they may glue the carpet to the floor or to padding that they have glued to the floor. On steps, they may use staples to hold the carpet in place. They also use carpet knives, carpet shears (scissors), hammers, power sanders, and other tools.

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:

• Clean rooms, hallways, and other living or work areas
• Change sheets and towels; make beds; wash, fold, and iron clothes
• Empty wastebaskets and take trash to disposal areas
• Replenish supplies, such as soap and toilet paper
• Dust and polish furniture and equipment
• Sweep, wax, or polish floors using brooms, mops, or other floor-cleaning equipment
• Vacuum rugs, carpets, and upholstered furniture
• Clean or polish windows, walls, and woodwork
• Lift and move lightweight objects and equipment

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.

Janitors and building cleaners keep many types of buildings clean, orderly, and in good condition.

Janitors and building cleaners typically do the following:

• Gather and empty trash and trash bins
• Clean building floors by sweeping, mopping, or vacuuming them
• Clean bathrooms and stock them with soap, toilet paper, and other supplies
• Keep buildings secure by locking doors
• Clean spills and other hazards using sponges and squeegees
• Wash windows, walls, and glass
• Order cleaning supplies
• Make minor repairs to the building, such as changing light bulbs
• Notify managers when the building needs major repairs

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.

Tile and marble setters apply hard tile, marble, and wood tiles to walls, floors, and other surfaces.

Tile and marble setters typically do the following:

• Clean and level the surface to be tiled
• Measure and cut tile and marble
• Arrange tiles according to the design plans
• Prepare and apply mortar or other adhesives
• Install tile and marble in the planned area
• Apply grout with a rubber trowel
• Wipe off excess grout and apply necessary finishes, such as sealants

Tile installers, tilesetters, and marble setters install materials on a variety of surfaces, such as floors, walls, ceilings, countertops, patios, and roof decks. Because tile and marble must be set on smooth, even surfaces, installers often must level the surface to be tiled with a layer of mortar or plywood. If the area to be tiled is unstable, workers must nail a support of metal mesh or tile backer board to create a stable surface.

To cut tiles, workers use power wet saws, tile scribes, or hand-held tile cutters to create even edges. They use trowels of different sizes to spread mortar or a sticky paste, called mastic, evenly on the surface to be tiled. To minimize imperfections and keep rows straight and even, they put spacers between tiles. The spacers keep tiles the same distance from each other until the mortar is dry. After the mortar dries and the tiles are set, they apply grout between tiles using a rubber trowel (called a float).

Marble setters may cut marble to a specified size with a power wet saw. After putting the marble in place, marble setters polish the marble to a high luster, using power or hand sanders.
