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.
Construction laborers and helpers held about 1.5 million jobs in 2020. Employment in the detailed occupations that make up construction laborers and helpers was distributed as follows:
- Construction laborers - 1,285,200
- Helpers--electricians - 75,500
- Helpers--pipelayers, plumbers, pipefitters, and steamfitters - 56,200
- Helpers--carpenters - 31,000
- Helpers, construction trades, all other - 27,800
- Helpers--brickmasons, blockmasons, stonemasons, and tile and marble setters - 20,900
- Helpers--painters, paperhangers, plasterers, and stucco masons - 9,400
- Helpers--roofers - 8,200
The largest employers of construction laborers and helpers were as follows:
- Specialty trade contractors - 34%
- Self-employed workers - 21%
- Construction of buildings - 18%
- Heavy and civil engineering construction - 16%
- Temporary help services - 3%
Most construction laborers and helpers perform physically demanding work. Some work at great heights or outdoors in all weather conditions; others may be required to work in tunnels. They must use earplugs around loud equipment and wear gloves, safety glasses, and other protective gear.
Injuries and Illnesses
Construction laborers and helpers, construction trades, all other have some of the highest rates of injuries and illnesses of all occupations. ("All other" titles represent occupations with a wide range of characteristics that do not fit into any of the other detailed occupations.)
Workers may experience cuts from materials and tools, fatal and nonfatal falls from ladders and scaffolding, and burns from chemicals or equipment. Some jobs expose workers to harmful materials, fumes, or odors, or to dangerous machinery. Workers may also experience muscle fatigue and injuries related to lifting and carrying heavy materials.
Like many construction workers, most laborers and helpers work full time. Although they must sometimes stop work because of bad weather, they may work overtime to meet deadlines. Laborers and helpers on highway and bridge projects may need to work overnight to avoid causing major traffic disruptions. In some parts of the country, construction laborers and helpers may work only during certain seasons. For example, in northern climates, cold weather frequently disrupts construction activity in the winter.
Some construction laborers are self-employed. In contrast, very few helpers are self-employed.Education & Training Required
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
