What defines a cross-section drawing?

• A. A method for distance measurement
• B. A drawing to calculate changes from existing to desired ground conditions
• C. A visual representation of elevation
• D. A schematic for utility placement

Answer: (B)

A cross-section drawing is accurately defined as a drawing created to analyze and illustrate the changes from existing ground conditions to the desired ground conditions. This type of drawing allows surveyors and planners to depict vertical slices of the terrain or project site, showing features such as soil layers, elevations, and proposed alterations. By representing these changes visually, cross-section drawings are essential in various engineering and construction projects, as they help identify how the terrain will be altered and how those changes will interact with existing conditions. This information is crucial for planning, compliance, and ensuring that the project meets design and regulatory requirements. While other types of drawings may serve specific functions—such as utility placement schematics providing infrastructure layouts, elevation drawings showcasing vertical height, or methods associated with distance measurement—the hallmark purpose of a cross-section drawing is its role in illustrating ground condition changes effectively.
