Answer 1

1)The correct answer is no.5 stake. Stakes are usually numbered in this way.

2)The correct answer is 10 feet offset. Here o/f mentions the offset.

3)The correct answer is place the reference marks or stakes to establish the location and elevation of the project.All the other options do not fall under this category or do not explain this concept.

4)The correct answer is the process of giving line consists in establishing a direction by turning a predetermined angle and placing a series of marks along the line at predetermined distances.

5)The correct answer is 0.2 ft.

6)The correct answer is 9.77 ft.

Value of Grade top = Value of HI – Value at blue top

7)The correct answer is cut 3.75 ft

Cut/Fill = HI –Stake reading – required grade

8)The correct answer is fill 4.6 ft

Cut/Fill = HI –Stake reading – required grade

9)The answer is Batter boards can show both horizontal location and grade.This is because the batter boards can only show horizontal location and not grade.

10)The correct answer is the single-beam laser can be used to give line.This is because ,it cannot be used to give line.
