Civil Engineering (Semester 4)

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.

Solve any four of the following.

1 (a) Draw a neat sketch of simple circular curve & show all elements.(5 marks) 1 (b) Explain use of computer in surveying.(5 marks) 1 (c) Explain principle of EDM.(5 marks) 1 (d) Explain field method to determine the constant of a techeometer?(5 marks) 1 (e) Differentiate between land survey and construction survey?(5 marks) 2 (a) Describe the principle of techeometry and differentiate between fixed hair method and movable hair method of techeometry.(8 marks) 2 (b) A fixed hair techeometer fitted with an anallatic lens with instruments constant of 100, was used to determine the slope between point P&Q. The following reading were taken. If the staff was held vertically, compute the gradient from P & Q.

Inst station	Staff station	Bearing	Reading of Stadia hair	Reading of axial hair	Vertical angle
A	P	345°	0.915 2.585	1.75	+15°
Q	75°	0.760 3.715	2.24	+10°

(12 marks) 3 (a) What is transition curves? Why it is provided, explain different types of transition curve.(10 marks) 3 (b) Two tangents intersect at chainage 1250m. The angle of intersection is 150° Calculate all data necessary for setting out a curve of radius 250m by the deflection angle method. The peg intervals may be taken as 20m.(10 marks) 4 (a) What do you understand by setting out work? Explain in detail the procedure for setting out work for a building.(10 marks) 4 (b) A gradient of -2.5% meets a gradient of +3.0% at a chainage of 1350 m and elevation of 140m. A vertical curve of length 200m is to be set out with pegs at 20m interval. Calculate the elevation of Pegs by chord gradient method.(10 marks) 5 (a) Compare a conventional theodolite with electronic theodolite.(10 marks) 5 (b) What is precise levelling? Which instruments are required for it? Explain how it is conducted in the field?(10 marks)

Write notes on

6 (a) Total station.(5 marks) 6 (b) GPS and Remote sensing.(5 marks) 6 (c) Subtense bar method.(5 marks) 6 (d) Use of laser in surveying.(5 marks)
