Construction Laborers - What They Do
Construction laborers can be found on almost all construction sites, performing a wide range of tasks from the very easy to the hazardous. They can be found at building, highway, and heavy construction sites; residential and commercial sites; tunnel and shaft excavations; and demolition sites. Many of the jobs they perform require physical strength, training, and experience. Other jobs require little skill and can be learned quickly. Although most construction laborers specialize in a type of construction, such as highway or tunnel construction, some are generalists who perform many different tasks during all stages of construction. Construction laborers who work in underground construction, such as in tunnels, or in demolition are more likely to specialize in only those areas.
Construction laborers clean and prepare construction sites. They remove trees and debris; tend pumps, compressors, and generators; and erect and disassemble scaffolding and other temporary structures. They load, unload, identify, and distribute building materials to the appropriate location according to project plans and specifications. Laborers also tend machines; for example, they may use a portable mixer to mix concrete or tend a machine that pumps concrete, grout, cement, sand, plaster, or stucco through a spray gun for application to ceilings and walls. They often help other craftworkers, including carpenters, plasterers, operating engineers, and masons.
Construction laborers are responsible for the installation and maintenance of traffic control devices and patterns. At highway construction sites, this work may include clearing and preparing highway work zones and rights-of-way; installing traffic barricades, cones, and markers; and controlling traffic passing near, in, and around work zones. Construction laborers also dig trenches; install sewer, water, and storm drainpipes; and place concrete and asphalt on roads. Other highly specialized tasks include operating laser guidance equipment to place pipes; operating air, electric, and pneumatic drills; and transporting and setting explosives for the construction of tunnels, shafts, and roads.
Some construction laborers help with the removal of hazardous materials, such as asbestos, lead, or chemicals.
Construction laborers operate a variety of equipment, including pavement breakers; jackhammers; earth tampers; concrete, mortar, and plaster mixers; electric and hydraulic boring machines; torches; small mechanical hoists; laser beam equipment; and surveying and measuring equipment. They may use computers and other high-tech input devices to control robotic pipe cutters and cleaners. To perform their jobs effectively, construction laborers must be familiar with the duties of other craftworkers and with the materials, tools, and machinery they use, as all of these workers work as part of a team, jointly carrying out assigned construction tasks.
Most construction laborers do physically demanding work. Some work at great heights or outdoors in all weather conditions. Some jobs expose workers to harmful materials or chemicals, fumes, odors, loud noises, or dangerous machinery. Some laborers may be exposed to lead-based paint, asbestos, or other hazardous substances during their work, especially when they work in confined spaces. Workers in this occupation experience one of the highest rates of nonfatal injuries and illnesses; consequently, the work requires constant attention to safety on the job. To avoid injury, workers in these jobs wear safety clothing, such as gloves, hardhats, protective chemical suits, and devices to protect their eyes, respiratory system, or hearing. While working underground, construction laborers must be especially alert in order to follow procedures safely and must deal with a variety of hazards.
A standard 40 hour work week is the most common work week for construction laborers. About 1 in 7 has a variable schedule, as overnight work may be required in highway work. In some parts of the country, construction laborers may work only during certain seasons. They also may experience weather-related work stoppages at any time of the year.
Although some construction laborer jobs have no specific educational qualifications or entry-level training, apprenticeships for laborers usually require a high school diploma or the equivalent. High school classes in English, mathematics, physics, mechanical drawing, blueprint reading, welding, and general shop can be helpful.
Most workers start by getting a job with a contractor who provides on-the-job training. Increasingly, construction laborers are finding work through temporary-help agencies that send laborers to construction sites for short-term work. Entry-level workers generally help more experienced workers, by performing routine tasks such as cleaning and preparing the worksite and unloading materials. When the opportunity arises, they learn from experienced construction trades workers how to do more difficult tasks, such as operating tools and equipment. Construction laborers also may choose or be required to attend a trade or vocational school, association training class, or community college to receive further trade-related training.
Some laborers receive more formal training in the form of an apprenticeship. These programs include between 2 and 4 years of classroom and on-the-job training. In the first 200 hours, workers learn basic construction skills, such as blueprint reading, the correct use of tools and equipment, and safety and health procedures. The remainder of the curriculum consists of specialized skills training in three of the largest segments of the construction industry: building construction, heavy and highway construction, and environmental remediation, such as lead or asbestos abatement and mold or hazardous waste remediation. Training in “green,” energy-efficient construction, an area of growth in the construction industry, is now available and can help workers find employment.
Workers who use dangerous equipment or handle toxic chemicals usually receive specialized safety training. Laborers who remove hazardous materials are required to take union- or employer-sponsored Occupational Safety and Health Administration safety training.
Apprenticeship applicants usually must be at least 18 years old and meet local requirements. Because the number of apprenticeship programs is limited, however, only a small proportion of laborers learn their trade in this way.
Laborers need manual dexterity, eye-hand coordination, good physical fitness, a good sense of balance, and an ability to work as a member of a team. The ability to solve arithmetic problems quickly and accurately may be required. In addition, military service or a good work history is viewed favorably by contractors.Construction Laborers - What They Do - Page 2
