Which sheets represent the profile grade point in a project?

The profile grade point in a project is represented by the plan and profile sheet, which is essential for showing the vertical alignment of the roadway, including the existing ground line, proposed finished grade, and the profile grade points. This sheet allows for a clear visualization of how the road will be laid out in relation to the terrain.

The typical section sheet provides information about the cross-sectional area of the highway at a given location, which complements the profile but does not specifically show grade points. The roadway cross-section sheets, while helpful for visualizing the width and depth of the road at various points, also do not depict the vertical alignment or grade points directly. Therefore, this combination of sheets (typical section sheet, plan and profile sheet, and roadway cross-section sheet) is critical for understanding the overall project layout, including profile grade points.
