Construction laborers and helpers learn their trade through on-the-job training (OJT). The length of training depends on the employer and the specialization. Formal education is not typically required.
Although formal education is not typically required, high school classes in mathematics, blueprint reading, welding, and other vocational subjects can be helpful.
To receive further education, some workers attend a trade school or community college.
Construction laborers and helpers learn through OJT after being hired by a construction contractor. Workers typically gain experience by performing tasks under the guidance of experienced workers.
Although the majority of construction laborers and helpers learn by assisting experienced workers, some construction laborers opt for apprenticeship programs. Programs generally include 2 to 4 years of technical instruction and OJT. The Laborers' International Union of North America (LIUNA) requires a minimum of 4,000 hours of OJT, accompanied by 300 hours of related instruction in such areas as signaling, blueprint reading, using proper tools and equipment, and following health and safety procedures. The remainder of the curriculum consists of specialized training in one of these eight areas:
Demolition and deconstruction
Road and utility construction
Several groups, including unions and contractor associations, sponsor apprenticeship programs, which usually have only a basic age qualification—age 18 or older—for entrance. Apprentices must obtain a high school diploma or equivalent before completing their apprenticeship. Some apprenticeship programs have preferred entry for veterans.
Depending on the work they do, laborers may need specific certifications, which may be attained through LIUNA. Rigging and scaffold building are commonly attained certifications. Certification can help workers prove that they have the knowledge to perform more complex tasks.
Through experience and training, construction laborers and helpers can advance into positions that involve more complex tasks. For example, laborers may earn certifications in welding, erecting scaffolding, or finishing concrete, and then spend more time performing those activities. Similarly, helpers sometimes move into construction craft occupations after gaining experience in the field. For example, experience as an electrician's helper may lead to becoming an apprentice electrician.
Color vision. Construction laborers and helpers may need to be able to distinguish colors to do their job. For example, an electrician's helper must be able to distinguish different colors of wire to help the lead electrician.
Math skills. Construction laborers and some helpers need to perform basic math calculations while measuring on jobsites or assisting a surveying crew.
Mechanical skills. Construction laborers are frequently required to operate and maintain equipment, such as jackhammers.
Physical stamina. Construction laborers and helpers must have the endurance to perform strenuous tasks throughout the day. Highway laborers, for example, spend hours on their feet—often in hot temperatures—with few breaks.
Physical strength. Construction laborers and helpers must often lift heavy materials or equipment. For example, cement mason helpers must move cinder blocks, which typically weigh more than 40 pounds each.
