Material moving machine operators use machinery to transport various objects. Some operators move construction materials around building sites or earth around a mine. Others move goods around a warehouse or onto and off of container ships.

Material moving machine operators typically do the following:

• Control equipment with levers, wheels, or foot pedals
• Move material according to a plan or schedule they receive from their superiors
• Set up and inspect material moving equipment
• Make minor repairs to their equipment
• Record the material they have moved and where they moved it from and to

In warehouse environments, most material moving machine operators use forklifts and conveyor belts. Automated sensors and tags are increasingly used to keep track of merchandise, allowing operators to work faster.

In warehouses, operators usually work closely with hand material movers. For more information, see the profile on hand laborers and material movers.

Many operators work for underground and surface mining companies. They help to dig or expose the mine, remove the earth and rock, and extract the ore and other mined materials.

In construction, material movers remove earth to clear space for buildings. Some work on a building site for the entire length of the construction project. For example, material moving machine operators often help to construct high-rise buildings by transporting materials to workers far above ground level.

The following are types of material moving machine operators:

Industrial truck and tractor operators drive trucks and tractors that move materials around warehouses, storage yards, or worksites. These trucks, often called forklifts, have a lifting mechanism and forks, which makes them useful for moving heavy and large objects. Some industrial truck and tractor operators drive tractors that pull trailers loaded with material around factories or storage areas.

Excavating and loading machine and dragline operators use machines equipped with scoops or shovels. They dig sand, earth, or other materials and load them onto conveyors for transport elsewhere. Most of these operators work in construction or mining industries.

Dredge operators excavate waterways. They remove sand, gravel, or rock from harbors or lakes to help prevent erosion and improve trade. Removing these materials helps maintain navigable waterways and allows larger ships to use more ports. Dredging is also used to help restore wetlands and maintain beaches.

Underground mining loading machine operators load coal, ore, and other rocks onto shuttles, mine cars, or conveyors for transport from a mine to the surface. These workers generally work underground in mines. They may use power shovels, hoisting engines equipped with scrapers or scoops, and automatic gathering arms that move materials onto a conveyor.

Crane and tower operators use tower and cable equipment to lift and move materials, machinery, or other heavy objects. Operators extend and retract horizontal arms and lower and raise hooks attached to cables at the end of their crane or tower. Operators are usually guided by other workers on the ground using hand signals or a radio. Most crane and tower operators work at construction sites or major ports, where they load and unload cargo. Some also work in iron and steel mills. 

Hoist and winch operators, also called derrick operators or hydraulic boom operators, control the movement of platforms, cables, and cages that transport workers or materials for industrial operations, such as constructing a high-rise building. Many of these operators raise platforms up far above the ground. Most work in manufacturing or construction industries. For more information about rig derrick equipment workers, see the profile on oil and gas workers.

Conveyor operators and tenders control conveyor systems that move materials on an automatic belt. They move materials to and from places such as building sites, storage areas, and vehicles.

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:

• Check to make sure that equipment functions properly
• Clean, maintain, and make basic repairs to equipment
• Report malfunctions to supervisors
• Move levers, push pedals, or turn valves to activate power equipment
• Drive and maneuver equipment
• Coordinate machine actions with crew members in response to hand or audio signals
• Ensure that safety standards are met

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:

• Asphalt spreader operators turn valves to regulate the temperature of asphalt and the flow of asphalt onto the roadbed. They must ensure that the machine distributes the paving material evenly, and they also must ensure that there is a constant flow of asphalt into the hopper.
• Concrete paving machine operators control levers and turn handwheels to move attachments that spread, vibrate, and level wet concrete. They must watch the surface of the concrete carefully to identify low spots into which workers must add concrete.
• Tamping equipment operators use machines that compact earth and other fill materials for roadbeds or other construction sites. They also may operate machines with interchangeable hammers to cut or break up old pavement and drive guardrail posts into the ground.

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.

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.
