What is the function of grade stakes in surveying?

The function of grade stakes in surveying primarily relates to indicating how much cut or fill is required for a construction project. Grade stakes are typically placed at specific points throughout a site to provide reference elevations based on the design plans. This information is crucial for construction crews, as it clarifies the necessary adjustments to be made to the existing grade.

When surveyors place these stakes, they usually indicate the final desired elevation or slope of the land. If the ground level needs to be lowered (cut) or raised (fill), the grade stakes will visually represent this need, guiding the earthmoving equipment on how much material should be removed or added. This ensures that the site can be sculpted to meet the design specifications, which is essential for proper drainage, structure placement, and overall project feasibility.

Each stake carries specific information regarding the elevation difference from the existing grade to the desired grade, allowing surveyors and contractors to execute grading work efficiently and accurately.
