JNTU II B.Tech I Semester

Supplimentary Examinations, November 2008


(Civil Engineering)




1. (a) Describe different types of chains and tapes commonly used in Surveying sta-

ting the advantages of each.

(b) Describe in detail how you would range and chain a line between two points which are not intervisible because of an intervening hillock.


2. (a) Explain the procedure of chaining. How will you record the measurements of

Chain Survey. Enumerate the points to be kept in view while booking the field notes.

(b) A Survey line BAC crosses a river, A and C being on the near and opposite

banks respectively. A perpendicular AD 40m long is set out at A. If the bearings of AD and DC are 380 451 and 2780 451 respectively and the chainage at A is 862m. find the chainage at C.


3. (a) What are the permanent adjustment of levels?

(b) Explain the principle of “reversion”.

(c) Name the principal lines in a dumpy level. List the conditions of adjustments.


4. (a) Name the three methods of measuring volume. For what purpose each one of these is use?

(b) Explain the measurement of volume from cross sections.


5. (a) What are ‘face left’ and ‘face right’ observations? Why is it necessary to take

both face observations?

(b) Why both verniers are read?

(c) Discuss various personal errors and errors due to natural causes in avernier



6. (a) What is tacheometry? Describe its uses.

(b) To determine the distance between two points P and Q, and the R.L. of Q, the following observations were made: Height of tacheometer at P=1.480 m Vertical angle at P= + 5020?

Staff readings (with staff vertical) = 0.545, 0.905, 1.265

R.L. of P=  150.000 m

k= 100.00 c=0.0


7. (a) What is a compound curve. If in a compound curve, the direction of the two

straights and one radius are known, deduce the formula for other radius.

(b) Tabulate the necessary data to set out a right handed simple circular curve of 600m radius to connect two straights intersecting at a chainage of 3605m by Rankine’s method of deflection angles. The angle of deflection of the curve is 250 and the peg interval is 30m.


8. What are the typical total station programs required to perform a variety of sur-

veying functions explain them briefly?
