What type of diagram is used to graphically represent the cumulative quantities of cut and fill?

The correct choice, Mass Diagram, serves a vital purpose in civil engineering and surveying when it comes to earthworks. A Mass Diagram visually depicts the quantities of earth that must be moved, whether excavated (cut) or added (fill), across a specific alignment or project area. It helps engineers and surveyors analyze the balance between cut and fill, facilitating efficient project planning and execution.

In the context of a Mass Diagram, the vertical axis typically represents the cumulative volume of material, while the horizontal axis reflects the stationing or distance along the alignment. As the diagram progresses, it shows areas where cut exceeds fill and vice versa, allowing for clear identification of where earthwork is needed. This tool is especially important for projects that involve significant earthmoving, as it assists in minimizing construction costs and ensuring environmental compliance by avoiding excessive hauling of materials.

Other choices, while related to surveying and civil engineering, do not fulfill the specific requirement of representing cumulative quantities of cut and fill as effectively as a Mass Diagram does. Topographic maps depict elevation and terrain but do not convey volume changes. Cross-sectional diagrams show profiles at a given point but do not illustrate cumulative quantities over distance. Graphical reports may contain various data but do not inherently focus on the cut and fill
