An excavation laborer works on a construction site running heavy machinery and performing manual labor to prepare the job site. You clean the work area and remove debris, transport material to and from the site, operate machines and trucks, and execute tasks as part of a team. As an excavation laborer, your duties span site preparation like digging trenches, grading, drilling, excavating for water features or sewers, hauling dirt and other discarded materials, and transporting equipment and crew members. Responsibilities vary widely based on the job site and project, but you generally work outside and in a variety of weather conditions.
