What is necessary for an operator to visualize during a grading job?

For an operator to successfully execute a grading job, it is critical to visualize both the desired grades and the existing grades. Understanding the existing grades is essential as this information allows the operator to gauge the current state of the terrain, identify high and low spots, and determine how much material needs to be added or removed to achieve the desired final grade.

On the other hand, the desired grades provide a target for the operator. This includes knowing the specifications of the project, such as drainage requirements or the final contour of the land, which are often defined in engineering plans or project specifications. By having a clear image of both current conditions and goals, the operator can make informed decisions and adjustments while operating the equipment to ensure that the grading is performed accurately and efficiently. Thus, a comprehensive understanding of both aspects is fundamental to the grading process.
