Code No: R1621015
II B. Tech I Semester Supplementary Examinations, May – 2018
SURVEYING (Civil Engineering)Time: 3 hours Max. Marks: 70
Note: 1. Question Paper consists of two parts (Part-A and Part-B) 2. Answer ALL the question in Part-A
3. Answer any FOUR Questions from Part-B
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PART-A
1 a) List the accessories of plane table.
b) Define latitude and departure.
c) List the leveling instruments
d) What are ?face left? and ?face right? observations? Why is it necessary to take
both face observations?
e) Write in detail about GPS.
f) How do you determine the earth work for a borrow pit?
PART-B
2 a) Compare the advantages and disadvantages of plane table surveying with those of
chain surveying.
b) State three-point problem plane tabling and describe its solution by trial method
giving the rules which you will follow in estimating position of the point sought
3 a) The following bearings are taken on a closed compass traverse.

Compute the interior angles and correct them for observational errors. Assuming the
observed bearing of the line AB to be correct, adjust the bearing of the remaining
sides.
4 a) What are the temporary adjustments of a leveling
b) What are the indirect methods of locating a contour? Write about any one method.
5 a) Write the temporary adjustments of a transit theodolite
b) Write the permanent adjustments of a theodolite
6 Two straights of a proposed road deflect through an angle of 1200. Originally, they
were to be connected by a curve of 520meters radius. However, due to the revision of
the scheme, the deflection angle is to be increased to 1320. Calculate the suitable
radius of the curve such that the original starting point of the curve (P.C.) does not
change

7 The following perpendicular offsets were taken at 10m intervals from a survey line to
an irregular boundary line:
3.25, 5.60, 4.20, 6.65, 8.75, 6.20, 3.25, 4.20, 5.65
Calculate the area enclosed between the survey line, the irregular boundary line and
the first and last offsets by Simpsons method.
