While most construction laborers tend to specialize in a type of construction, such as highway or tunnel construction, they are generalists who perform many different tasks during all stages of construction. However, construction laborers who work in underground construction (such as in tunnels) or in demolition are more likely to specialize in only those areas. Other highly specialized tasks Laborers perform include operating laser guidance equipment to place pipes, operating air, electric, and pneumatic drills, and transporting and setting explosives for tunnel, shaft, and road construction. Tunnel projects are becoming more prevalent each year and this work includes tunnel safety, rail and shoring, utilities installation and locomotive operation.
