Q.17. Outline how to use a water level.
Q.18 (a). Define the terms as below:
Q18 b. What does the diagram below show?

Q.20. A line of levels is run from BM10 to BM11. At BM10 the elevation is 101.325 m in the Australian Height Datum (AHD). The following observations were taken:
All the level setups are equally distant between back- and foresights to reduce error. Use the rise and fall method to work out the levels in order to find the elevation of BM11.
Q. A line of levels is run from BM104 to BM105. At BM104 the elevation is 692.123 m in the Australian Height Datum. The backsights and foresights are as follows.
Use the rise and fall method to work out the levels in order to find the elevation of BM105 (foresight at D).
Q.21. The staff readings, as shown below, were obtained in a leveling exercise. Tabulate the data in a leveling form and calculate the adjusted reduced levels of P, Q, and R using the rise and fall method. All mathematical checks are to be included. The staffs at R and Q were held inverted.
Q.22. This was run in two directions. Fill out the observation form (backsights, foresight, and intermediate sights) and reduce the observations using the collimation height method.
Q.23 A two-peg test of a level produced the following results:
Given that the distance A to B is 60 m, calculate the sign and magnitude of the collimation error.
Q.24 Levels were taken at 25 m intervals along the centreline of the proposed work. If the formation is to have a gradient of -1% starting at elevation 222.92 m at Peg K, calculate the amount of cut (-) or fill (+) required at each peg. Use the collimation height method of reduction.
Q.25. List tools used for setting out.
Q.26. What is a survey peg?
Q.27. Describe what a boundary is.
Q.28. Describe a hurdle.
Q.29. Why do you keep the hurdle level?
Q.30. Explain why is it important that measurements be taken on a horizontal plane.
Q.31. Sketch a means of measuring a horizontal distance down a sloping site.
