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. List the obstacles in chaining and explain in detail with sketches.
A tape of standard length 20 m at 85°F was used to measure a base line. The measured distance
was 882.50 m. The following Table 1 being the slopes for the various segments of the line.
Calculate the true length of the line if the mean temperature during measurement was 63°F and

the coefficient of thermal expansion of the tape material is 6:5 per F.
2. Describe the principles of surveying.

UNIT II
3. The following staff reading was observed successively with a level, the instrument was moved
after third, sixth and eight reading: 2.230, 1.605, 0.985, 2.090, 2.845, 1.260, 0.600, 1.980, 1.045
and 2.685. Enter the above reading in a page of level book and calculate the RL of points if the
first reading was taken with staff held on bench mark of 432.385 m. Adopt rise and fall method.

With sketches describe the characteristics of contours.
4. The following consecutive readings were taken along AB with a 4m leveling staff on continuously
slowing ground at intervals of 20m: 0.340m on 1.450,2.630,3.875,0.655,1.745,2.965,3.945,1.125,2.475,3.865
on B. The elevation A was 60.350. Enter the above readings in a level book form and compute
reduced levels by height of instrument method. Also find the gradient of the line AB.
Describe the method indirect contouring using block leveling and plotting of contours.
UNIT III
5. The following offsets were taken from a chain line to an irregular boundary line at an interval of
10 m. 2.50, 3.50, 5.00, 4.60, 3.20, 0 m. Compute the area between the chain line, the irregular
boundary line and the end offsets by Trapezoidal Rule and Simpson's Rule
An embankment of width 10 m and side slopes 1 ½:1 is required to be made on a ground which
is level in a direction transverse to the center line. The center heights at 40 m intervals are as
follows: 0.90, 1.25, 2.15, 2.50, 1.85, 1.35, and 0.85 Calculate the volume of earth work according
to
Trapezoidal formula
ii) Prismoidal formula
6. The following Table 3 offsets were taken from a chain line to a hedge Calculate the area

The areas within the contour lines at the side of a reservoir and along the face of a proposed dam
are shown in Table 4.
If the bottom level is 238.0m and Full supply level is 250.0m, determine the capacity of the
reservoir by any two methods.
