• Laying out construction projects according to planned elevations

• Calculating volumes of earthwork and other materials

• All of the above

What is a benchmark?

• A temporary point of known elevation

• A reference surface to which elevations of points are referred

• A permanent point of known elevation

• An imaginary surface of the sea

What is the purpose of a turning point in leveling?

• To measure the difference in elevation between two points

• To establish a reference point for leveling

• To calculate the volume of earthwork
