### Civil Engineering (Semester 3)

TOTAL MARKS: 80
TOTAL TIME: 3 HOURS
(1) Question 1 is compulsory.
(2) Attempt any three from the remaining questions.
(3) Assume data if required.
(4) Figures to the right indicate full marks.
1 (a) Explain cumulative and compensating errors in chaining.(4 marks) 1 (b) Describe temporary adjustment of prismatic compass.(4 marks) 1 (c) Explain the reciprocal levelling and state its advantages.(4 marks) 1 (d) Differentiate between consecutive co-ordinate and independent coordinate.(4 marks) 1 (e) Explain the characteristics of contour lines.(4 marks) 1 (f) Explain geodetic surveying.(4 marks) 2 (a) Write short notes on compound levelling and profile levelling.(5 marks) 2 (b) A chaining pass a porid,stations P and Q were selected on opposite side of the pond. A line PA,200 m long, was set out of the left of PQ ,and a line PB was set out on the right such that A,Q and B are collinear. The length of PB was 250m. The length of AQ and QB were meassured to be 125m and 150m respectively. The chainage at P is 1020.55m. Calculate the chainage of Q.(5 marks) 2 (c) The following bearings were observed while traversing with compass. Find which stations are affected by local attractions and work out corrected bearing of the lines of closed traverse.

(10 marks) 3 (a) Write exhaustive note on 'obstacles in chaining'.(5 marks) 3 (b) Explain the various type of bench marks used in levelling.(5 marks) 3 (c) The following staff reading were observed with a level & a 4 m staff on a continuously sloping ground at a common nterval of 15m. The reading are 0.880,1.632,2.530,3.085,3.580,1.255,2.060,2.465,3.740,1.035,1.145,1.1730 and 2.645. The reduced level of the first point was 780.150.
