During excavation and fill activities, slope control is handled with grade stakes that are placed by ________.

• A. Inspector
• B. Survey crew
• C. Construction manager
• D. Equipment operator

Answer: (B)

Grade stakes are the reference markers that show the exact elevations and lines the earthmoving crew must hit to control slope during excavation and fill. They translate the design plan into on-the-ground targets so the ground is shaped to the intended contours and drainage. The survey crew places these stakes because they establish accurate grade and alignment across the site, using instruments like levels, total stations, or GPS to set precise points. With stakes in place, the equipment operator can cut or fill to the specified elevations and slopes, ensuring the work matches the design.
