All City Carpet Cleaning

Environmental engineering technicians engineering technicians carry out the plans that environmental engineers develop.

Environmental engineering technicians typically do the following:

• Set up, test, operate, and modify equipment for preventing or cleaning up environmental pollution
• Maintain project records and computer program files
• Conduct pollution surveys, collecting and analyzing samples such as air and ground water
• Perform indoor and outdoor environmental quality work
• Work to mitigate sources of environmental pollution
• Review technical documents to ensure completeness and conformance to requirements
• Review work plans to schedule activities
• Arrange for the disposal of lead, asbestos, and other hazardous materials

In laboratories, environmental engineering technicians record observations, test results, and document photographs. To keep the laboratory supplied, they also may get product information, identify vendors and suppliers, and order materials and equipment.

Environmental engineering technicians also help environmental engineers develop devices for cleaning up environmental pollution. They also inspect facilities for compliance with the regulations that govern substances such as asbestos, lead, and wastewater.

Craft and fine artists use a variety of materials and techniques to create art for sale and exhibition. Craft artists create handmade objects, such as pottery, glassware, textiles or other objects that are designed to be functional. Fine artists, including painters, sculptors, and illustrators, create original works of art for their aesthetic value, rather than a functional one.

Craft and fine artists typically do the following:

• Use techniques such as knitting, weaving, glass blowing, painting, drawing, or sculpting
• Develop creative ideas or new methods for making art
• Create sketches, templates, or models to guide their work
• Select which materials to use on the basis of color, texture, strength, and other qualities
• Process materials, often by shaping, joining, or cutting
• Use visual elements, such as composition, color, space, and perspective, to produce desired artistic effects
• Develop portfolios highlighting their artistic styles and abilities to show to gallery owners and others interested in their work

Artists create objects that are beautiful or thought-provoking. They often strive to communicate ideas or feelings through their art.

Craft artists make a wide variety of objects, mostly by hand, to sell in their own studios, online, in stores, or at arts-and-crafts shows. Some craft artists display their works in galleries and museums.

Craft artists work with many different materials, including ceramics, glass, textiles, wood, metal, and paper, to create unique pieces of art, such as pottery, quilts, stained glass, furniture, jewelry, and clothing. Many craft artists also use fine-art techniques--for example, painting, sketching, and printing--to add finishing touches to their products.

Fine artists typically display their work in museums, commercial or non-profit art galleries, corporate collections, and private homes. Some of their artwork may be commissioned (requested by a client), but most is sold by the artist or through private art galleries or dealers. The gallery and the artist decide in advance how much of the sale proceeds each will keep.

Some craft and fine artists spend much time and effort selling their artwork to potential customers or clients and building a reputation. However, only the most successful artists are able to support themselves solely through the sale of their works. Many artists have at least one other job to support their craft or art careers.

Some artists work in museums or art galleries as arts directors or as curators, planning and setting up exhibits. Others teach craft or art classes or conduct workshops in schools or in their own studios. For more information on workers who teach art classes, see the profiles on kindergarten and elementary school teachers, middle school teachers, high school teachers, postsecondary teachers, and self-enrichment teachers.

Craft and fine artists specialize in one or more types of art. The following are examples of types of craft and fine artists:

Cartoonists draw political, advertising, comic, and sports cartoons. Some cartoonists work with others who create the idea or story and write captions. Some create plots and write captions themselves. Most cartoonists have comic, critical, or dramatic talents in addition to drawing skills.

Ceramic artists shape, form, and mold artworks out of clay, often using a potter's wheel and other tools. They glaze and fire pieces in kilns, which are special furnaces that dry and harden the clay.

Fiber artists use fabric, yarn, or other natural and synthetic fibers to weave, knit, crochet, or sew textile art. They may use a loom to weave fabric, needles to knit or crochet yarn, or a sewing machine to join pieces of fabric for quilts or other handicrafts.

Fine art painters paint landscapes, portraits, and other subjects in a variety of styles, ranging from realistic to abstract. They may use one or more media, such as watercolors, oil paints, or acrylics.

Furniture makers cut, sand, join, and finish wood and other materials to make handcrafted furniture. For more information about other workers who assemble wood furniture, see the profile on woodworkers.

Glass artists process glass in a variety of ways--such as by blowing, shaping, or joining it--to create artistic pieces. Specific processes used include glassblowing, lampworking, and stained glass. These workers also decorate glass objects, such as by etching or painting.

Illustrators create pictures for books, magazines, and other publications, and for commercial products, such as textiles, wrapping paper, stationery, greeting cards, and calendars. Increasingly, illustrators use computers in their work. They might draw in pen and pencil and then scan the image into a computer to be colored in, or use a special pen to draw images directly onto the computer.

Sketch artists, a particular type of illustrator, often create likenesses of subjects with pencil, charcoal, or pastels. Sketches are used by law enforcement agencies to help identify suspects, by the news media to show courtroom scenes, and by individual customers for their own enjoyment.

Jewelry artists use metals, stones, beads, and other materials to make objects for personal adornment, such as earrings or bracelets. For more information about other workers who create jewelry, see the profile on jewelers and precious stone and metal workers.

Medical and scientific illustrators combine drawing skills with knowledge of biology or other sciences. Medical illustrators work with computers or with pen and paper to create images of human anatomy and surgical procedures, as well as three-dimensional models and animations. Scientific illustrators draw animal and plant life, atomic and molecular structures, and geologic and planetary formations. These illustrations are used in medical and scientific publications and in audiovisual presentations for teaching purposes. Some medical and scientific illustrators work for lawyers, producing exhibits for court cases.

Printmakers create images on a silk screen, woodblock, lithography stone, metal etching plate, or other type of matrix. The matrix is then inked and transferred to a piece of paper using a printing press or hand press to create the final work of art. Workers who do photoengraving are called printing workers. For more information, see the profile on printing workers.

Sculptors design three-dimensional works of art, either by molding and joining materials such as clay, glass, plastic, or metal, or by cutting and carving forms from a block of plaster, wood, or stone. Some sculptors combine various materials to create mixed-media installations. For example, some incorporate light, sound, and motion into their works.

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.

Roofers repair and install the roofs of buildings using a variety of materials, including shingles, asphalt, and metal.

Roofers typically do the following:

• Inspect problem roofs to determine the best way to repair them
• Measure roof to calculate the quantities of materials needed
• Replace damaged or rotting joists or plywood
• Install vapor barriers or layers of insulation
• Install shingles, asphalt, metal, or other materials to make the roof watertight
• Align roofing materials with edges of the roof
• Cut roofing materials to fit angles formed by walls, vents, or intersecting roof surfaces
• Cover exposed nail or screw heads with roofing cement or caulk to prevent leakage

Properly installed roofs keep water from leaking into buildings and damaging the interior, equipment, or furnishings.

There are two basic types of roofs, low-slope and steep-slope:

• Low-slope: About two-thirds of all roofs are low-slope. Most commercial, industrial, and apartment buildings have low-slope roofs. Low-slope roofs rise 4 inches or less per horizontal foot and are installed in layers.
  
  For low-slope roofs, roofers typically use several layers of roofing materials or felt membranes stuck together with hot bitumen (a tar-like substance). They glaze the top layer to make a smooth surface or embed gravel in the hot bitumen to make a rough surface.
  
  An increasing number of low-slope roofs are covered with a single-ply membrane of waterproof rubber or thermoplastic compounds.

• Steep-slope: Most of the remaining roofs are steep-slope. Most single-family houses have steep-slope roofs. Steep-slope roofs rise more than 4 inches per horizontal foot.
  
  For steep-slope roofs, roofers typically use asphalt shingles, which often cost less than other coverings. On steep-slope roofs, some roofers also install tile, solar shingles, fiberglass shingles, metal shingles, or shakes (rough wooden shingles).
  
  To apply shingles, roofers first lay, cut, and tack 3-foot strips of roofing over the entire roof. Then, starting from the bottom edge, they nail overlapping rows of shingles to the roof.

A small but increasing number of buildings now have “green” roofs that incorporate landscape roofing systems. A landscape roofing system typically begins with a single or multiple waterproof layers. After that layer is proven to be leak free, roofers put a root barrier over it, and, finally, layers of soil, in which vegetation is planted. Roofers must ensure that the roof is watertight and can endure the weight and water needs of the plants.

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.
