Construction managers plan, coordinate, budget, and supervise construction projects from early development to completion.
Construction managers typically do the following:
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.
Construction equipment operators drive, maneuver, or control the heavy machinery used to construct roads, bridges, buildings, and other structures.
Construction equipment operators typically do the following:
Construction equipment operators use machinery to move construction materials, earth, and other heavy materials at construction sites and mines. They operate equipment that clears and grades land to prepare it for construction of roads, bridges, and buildings, as well as airport runways, power generation facilities, dams, levees, and other structures.
The following are types of construction equipment operators:
Operating engineers and other construction equipment operators work with one or several types of power construction equipment. They may operate excavation and loading machines equipped with scoops, shovels, or buckets that dig sand, gravel, earth, or similar materials. In addition to operating the familiar bulldozer, they operate trench excavators, road graders, and similar equipment. Sometimes, they may drive and control industrial trucks or tractors equipped with forklifts or booms for lifting materials. They also may operate and maintain air compressors, pumps, and other power equipment at construction sites.
Paving and surfacing equipment operators control the machines that spread and level asphalt or spread and smooth concrete for roadways or other structures. Paving and surfacing equipment operators may specialize further:
Piledriver operators use large machines mounted on skids, barges, or cranes to hammer piles into the ground. Piles are long, heavy beams of wood or steel driven into the ground to support retaining walls, bridges, piers, or building foundations. Some piledriver operators work on offshore oil rigs.
Some workers operate cranes to move construction materials. For more information on these workers, see the profile on material moving machine operators.
Grounds maintenance workers provide a pleasant outdoor environment by ensuring that the grounds of houses, businesses, and parks are attractive, orderly, and healthy.
Grounds maintenance workers typically do the following:
Grounds maintenance workers do a variety of tasks to achieve a pleasant and functional outdoor environment. They also care for indoor gardens and plantings in commercial and public facilities, such as malls, hotels, and botanical gardens.
The following are types of grounds maintenance workers:
Landscaping workers create new outdoor spaces or upgrade existing ones by planting trees, flowers, and shrubs. They also trim, fertilize, mulch, and water plants. Some grade and install lawns or construct hardscapes such as walkways, patios, and decks. Others help install lighting or sprinkler systems. Landscaping workers work in a variety of residential and commercial settings, such as homes, apartment buildings, office buildings, shopping malls, and hotels and motels.
Groundskeeping workers, also called groundskeepers, maintain existing grounds. They care for plants and trees, rake and mulch leaves, and clear snow from walkways. They work on athletic fields, golf courses, cemeteries, university campuses, and parks, as well as in many of the same settings as landscaping workers. They also see to the proper upkeep and repair of sidewalks, parking lots, groundskeeping equipment, fountains, fences, planters, and benches.
Groundskeeping workers who care for athletic fields keep natural and artificial turf in top condition, mark out boundaries, and paint turf with team logos and names before events. They mow, water, fertilize, and aerate the fields regularly. They must make sure that the underlying soil on fields with natural turf has the required composition to allow proper drainage and to support the grasses used on the field. In sports venues, they vacuum and disinfect synthetic turf after its use to prevent the growth of harmful bacteria, and they remove the turf and replace the cushioning pad periodically.
Groundskeepers in parks and recreation facilities care for lawns, trees, and shrubs; maintain playgrounds; clean buildings; and keep parking lots, picnic areas, and other public spaces free of litter. They also may erect and dismantle snow fences, and maintain swimming pools. These workers inspect buildings and equipment, make needed repairs, and keep everything freshly painted.
Some groundskeepers specialize in caring for cemeteries and memorial gardens. They dig graves to specified depths, generally using a backhoe. They mow grass regularly, apply fertilizers and other chemicals, prune shrubs and trees, plant flowers, and remove debris from graves.
Greenskeepers maintain golf courses. Their work is similar to that of groundskeepers, but they also periodically relocate holes on putting greens and maintain benches and tee markers along the course. In addition, greenskeepers keep canopies, benches, and tee markers repaired and freshly painted.
Pesticide handlers, sprayers, and applicators apply herbicides, fungicides, or insecticides on plants or the soil to prevent or control weeds, insects, and diseases. Those who work for chemical lawn or tree service firms are more specialized, inspecting lawns for problems and applying fertilizers, pesticides, and other chemicals to stimulate growth and prevent or control weeds, diseases, or insect infestations.
Tree trimmers and pruners, also called arborists, cut away dead or excess branches from trees or shrubs to clear utility lines, roads, and sidewalks. Although many workers strive to improve the appearance and health of trees and plants, some specialize in diagnosing and treating tree diseases. Others specialize in pruning, trimming, and shaping ornamental trees and shrubs. Tree trimmers and pruners use chainsaws, chippers, and stump grinders while on the job. When trimming near power lines, they usually work on truck-mounted lifts and use power pruners.
Plasterers and stucco masons apply coats of plaster or stucco to walls, ceilings, or partitions for functional and decorative purposes. Some workers apply ornamental plaster.
Plasterers and stucco masons typically do the following:
Plasterers apply coats of plaster to interior walls and ceilings to form fire-resistant and relatively soundproof surfaces. Using trowels, workers spread plaster on solid surfaces, such as concrete block, or supportive wire mesh called lath. They also may apply plaster over drywall to create smooth or textured scratch-resistant finishes. Using molds and a variety of troweling techniques, some plasterers make decorative and ornamental designs, which require special skills and creativity.
Plasterers may also install prefabricated exterior insulation systems over existing walls--for good insulation and interesting architectural effects--and cast ornamental designs in plaster.
Stucco masons usually apply stucco--a mixture of cement, lime, and sand--on building exteriors over wire lath, concrete, or masonry. Stucco masons also may apply other durable plasters, such as polymer-based acrylic finishes, to exterior surfaces. Stucco masons may also embed marble or gravel chips into the finish coat to achieve a pebble-like, decorative finish.
In addition, when required, stucco masons apply insulation to the exterior of new and old buildings. They cover the outer wall with rigid foam insulation board and reinforcing mesh, and then trowel on a base coat.
Painters apply paint, stain, and coatings to walls, buildings, bridges, and other structures.
Painters typically do the following:
Applying paint to interior walls makes surfaces attractive and vibrant. In addition, paints and other sealers protect exterior surfaces from erosion caused by exposure to the weather.
Because there are several ways to apply paint, workers must be able to choose the proper tool for each job, such as the correct roller, power sprayer, and the right size brush. Choosing the right tool typically depends on the surface to be covered and the characteristics of the finish.
A few painters--mainly industrial--must use special safety equipment. For example, painting in confined spaces such as the inside of a large storage tank, requires workers to wear self-contained suits to avoid inhaling toxic fumes. When painting bridges, tall buildings, or oil rigs, painters may work from scaffolding, bosun's chairs, and harnesses to reach work areas.
The following are examples of types of painters:
Construction painters apply paints, stains, and coatings to interior and exterior walls, new buildings, and other structural surfaces.
Maintenance painters remove old finishes and apply paints, stains, and coatings later in a structure's life. Some painters specialize in painting or coating industrial structures, such as bridges and oil rigs, to prevent corrosion.
Artisan painters specialize in creating distinct finishes by using one of many decorative techniques. One technique is adding glaze for added depth and texture. Other common techniques may include sponging, distressing, rag-rolling, color blocking, and faux finishes.
Painting and coating workers apply materials to manufactured products, such as furniture, toys and pottery, as well as transportation equipment including trucks, buses, boats, and airplanes. For more information about these painters, see the profile on painting and coating workers.
