When verifying design grades in the field, what elevations must you confirm?

• A. Finished elevations only.
• B. Finished elevations, grade stakes, and cross-section elevations to match design.
• C. Grade stakes only.
• D. Cross-section elevations only.

Answer: (B)

Verifying design grades in the field means checking multiple measurements against the plan to ensure the built surface matches the design. Finished elevations show the final ground level at specific points, and you compare these to the design elevations to confirm the surface is at the correct height. Grade stakes tell you where to cut or fill and by how much, so checking them ensures the earthmoving work places material to the intended depths and locations. Cross-section elevations reveal the ground profile across the width at various stations, so confirming these ensures the slopes, thicknesses, and drainage features line up with the design. Using the right tools and techniques to measure and compare these three elements together ensures the entire grade aligns with the plan, not just one aspect.
