Answer ONE Question from each Unit
All Questions Carry Equal Marks
All parts of the question must be answered in one place only
UNIT I
1. State the objectives of Surveying? What is a well-conditioned triangle and mention the necessity
of well-conditioned triangles?
Table 1 below shows the bearings observed in a traverse survey conducted with a prismatic
compass at a place where local attraction was suspected? At what stations do you suspect local
attraction? Find the corrected bearings of the lines and compute the interior angles.

A 20m steel tape was standardized on a flat ground at temperature of 200C under a pull of 15kg.
The tape was used in catenary at a temperature of 300 C under a pull of 10kg. The cross sectional
area of the tape is 22mm2 and its total weight is 400 gm, the Youngs modulus and co-efficient
of thermal expansion for steel are 21000 kg/mm2 and 11 x per C respectively. Find the
correct distance
UNIT II
3. What is a contour? Explain the characteristics of contours with neat sketches.
The following staff readings were observed successively with a level. The instrument having been
moved after the second, fifth and seventh readings. 0.675, 1.230, 0.750, 2.565, 2.225, 1.935, 1.835,
3.115 and 2.875. The first reading was taken with a staff held on a bench mark of reduced level
+100.000. Enter the readings in the level book form and find the reduced level of all the points.

instrument.
Describe the various types of leveling instruments with neat sketches

The following perpendicular offsets were taken at 10 m intervals from a survey line to an irregular
boundary line 2.95, 5.70, 4.00, 6.35, 8.25, 6.00, 3.30, 4.85, 5.70. Calculate the area included
between the survey line,the irregular boundary line, and the first and last offsets by Mid
Ordinate rule ii) Trapezoidal rule
6. State and derive Simpson's rule and write down its limitations.
A road embankment is 18m wide at the formation level with side slopes of 2 1. The average
height of the embankment is 6m with an average gradient of 1 in 30 from a 230m contour to
350m contour. Find the length of the road and the quantity of earthwork.
UNIT IV
7. Draw a neat sketch of theodolite and describe purpose of various components? Why both Verniers
are read?
What are the different errors in theodolite work? How they are eliminated?
8. Discuss the procedure of measuring horizontal angle with a theodolite.
An instrument was set up at P and the angle of elevation to a vane 4m above the foot of the staff
held at Q was 90 301. The horizontal distance between P and Q was known to be 2000 meters.
Determine the R.L. of the staff station given that the R.L. of the instrument axis was
2650.38 m.
UNIT V
9. List out the advantages and disadvantages of a total station. Explain the functions of the various
parts of total station.
