(CONSTRUCTION MANAGEMENT)
(THIRD SEMESTER)
330: SURVEYING
Time: Three hours Maximum: 75 marks
Answer ONE FULL question from each UNIT (5 × 15 = 75)
UNIT-I
1. a) Explain the principle and Chain Surveying? (6)
b) In passing an obstacle in the form of a pond, stations A and D, on the
main line, were taken on the opposite sides of the pond. On the left of
AD, a line AB 225 m long was laid down, and a second lineAC 275m
long was ranged on the right of AD. The points B, D and C being in the
same straight line. BD and DC were then chained and found to be 125
m and 137.5 m respectively. Find the length of AD.
(9)
(OR)
2. a) Explain the following terms: (i) Check line, (ii) Base line (iii) Tie line (6)
b) Describe how you would range a chain line between two points which
are not inter-visible.
(9)
UNIT-II
3. a) Explain the various methods of plane tabling? (6)
b) Explain clearly the differences between a prismatic compass and
surveyor’s compass.
(9)
(OR)
4. a) Define the terms (i) Benchmark (ii) Parallax (iii) Reduced level (3)
b) The following staff reading were observed successively with level, the
instrument having been moved forward after the second, fourth and
eighth readings: 0.875, 1.235, 2.310, 1.385, 2.930, 3.125, 3.975,
0.120, 1.875, 20.30, 3.765. The first reading was taken with the staff
held upon a bench mark of elevation 132.135. Enter the readings in
level book form and reduce the levels. Apply the usual checks. Find
also the difference in level between the first and the last points.

UNIT-III
5. The following offsets were taken from a chain line to a hedge.
Distance
(m)
0 6 12 18 24 36 48 60 72 81 90
Offset
(m)
3.60 3.00 2.40 1.80 1.20 1.50 2.10 2.40 3.00 3.30 3.90
Calculate the area enclosed between the chain line, hedge and the end
offsets by (i) Simson’s rule (ii) Trapezoidal rule.
(15)
(OR)
6. The area within the contour lines at the site of a reservoir and the face of
the proposed dam are as follows:

Contour in m Area in m2
450 270
452 10,400
454 75,600
456 1,44,000
458 2,70,000
460 4,14,500
462 4,60,800
464 5,86,800
466 6,39,900
Taking 450 as the bottom level of the reservoir and 466 as the water level,
find the volume of water in the reservoir.

UNIT-IV
7. a) How do you adjust the closed error in a theodolite traverse? Explain in
detail.
(6)
b) Explain with neat sketches to set out tangential curves by theodolite. (9)
(OR)
8. a) How do you determine the tachometric constants? (6)
b) Compare and contrast the tangential and stadia system of techometry? (9)
UNIT-V
9. a) Explain in detail about the some mine survey instruments? (6)
b) Differentiate between plane surveying and geodetic surveying and write
down the basic characteristics of each?
(9)
(OR)
10. a) What are the various software’s available of GIS? (6)
b) Explain in detail about the various principles of ‘Distometer’ and ‘GPS’? (9)
