What is Construction Drillers and Excavators Job Description ?
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, buildings, and bridges. They use machines to dig trenches to lay or repair sewer and other pipelines and hoist heavy construction materials. They may even work offshore constructing oil rigs. Construction equipment operators also operate machinery that spreads asphalt and concrete on roads and other structures.
These workers also set up and inspect the equipment, make adjustments, and perform some maintenance and minor repairs. Construction equipment operators control equipment by moving levers, foot pedals, operating switches, or joysticks. Construction equipment is more complicated to use than it was in the past. For example, Global Positioning System (GPS) technology is now being used to help with grading and leveling activities.
Included in the construction equipment operator occupation are paving, surfacing, and tamping equipment operators; piledriver operators; and operating engineers. Paving and surfacing equipment operators use levers and other controls to operate machines that spread and level asphalt or spread and smooth concrete for roadways or other structures. Asphalt paving machine operators turn valves to regulate the temperature and flow of asphalt onto the roadbed. They must take care that the machine distributes the paving material evenly and without voids, and make sure that there is a constant flow of asphalt going into the hopper. Concrete paving machine operators control levers and turn handwheels to move attachments that spread, vibrate, and level wet concrete in forms. They must observe the surface of concrete to identify low spots into which workers must add concrete. They use other attachments to smooth the surface of the concrete, spray on a curing compound, and cut expansion joints. Tamping equipment operators operate tamping 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 earth.
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, bulkheads, bridges, piers, or building foundations. Some piledriver operators work on offshore oil rigs. Piledriver operators move hand and foot levers and turn valves to activate, position, and control the pile-driving equipment.
Operating engineers and other construction equipment operators use 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 and load it into trucks or onto conveyors. In addition to the familiar bulldozers, 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 or with hitches for pulling trailers. They also may operate and maintain air compressors, pumps, and other power equipment at construction sites. Construction equipment operators who are classified as operating engineers are capable of operating several different types of construction equipment.
