Rough grading is primarily performed using earthmoving equipment like bulldozers, which are specifically designed for this purpose. These machines are capable of moving large volumes of soil efficiently and quickly, leveling the ground, and removing or adding earth to create the desired contours and elevations for a construction site.

The process involves cutting (removing soil) and filling (adding soil), which is best suited to heavy machinery due to the scale of work typically involved. Bulldozers, for example, can push earth over significant distances in a streamlined manner, making them the preferred choice for this aspect of land development.

The other options involve techniques or methods that are not appropriate for rough grading. Hand tools and shovels are inefficient for the scale required in most grading projects. Compaction is a process that comes after grading, ensuring the soil is stable but does not itself involve the shaping of the land. Irrigation techniques are related to water management and soil moisture control, which do not pertain to the rough grading process. Thus, the use of bulldozers and similar heavy equipment is essential in executing rough grading effectively.
