Surveying - 2 - May 2015

Civil Engineering (Semester 4)

(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.

Attempt any two questions.

1 (a) Explain in detail the field procedure for setting out the curve by Rankine's method of deflection angles.(10 marks) 1 (b) Explain in detail the procedure along with neat sketch the tachometric radial contouring project along with method employed for plotting the contours.(10 marks) 1 (c) Explain
i) Principle of EDM
ii) Principle of tacheometry.
(10 marks)

Differentiate between

2 (a) i) Stadia system and tangential system of tacheometry.
ii) Fixed hair method and moveable hair method of stadia tacheometory.
(10 marks)
2 (b) To determine the distance between two point X and Y and their elevations. Following observation were recorded upon vertically held staves from two traverse stations R and S. The tacheometer was fitted with an analytic lens and instrument constant was 100. compute the distance XY gradient from X to Y and bearing of XY

(10 marks) 3 (a) Explain in brief the procedure for setting out a simple circular curve by the method of offset from chord produced.(10 marks) 3 (b) In making a survey for a new road , the intersection point of two straights was found to be inacessible. Four points P,Q,R,S were therefor selected two on each straight, and the distance between Q and R was found to be 122.20m. If the angle PQR was 160°47'40' and angle QRS 148°22'20''; Draw up a table of deflection angles and chainages for setting out a 200m radius curve by pegs driven at every 20m chain. Chainage of Q=(140+90) chains.(10 marks) 4 (a) Define setting out of works and explain in brief the detailed procedure for setting out of bridge.(10 marks) 4 (b) What is total station. Mention the advantages of total station over level and theodolite along with the uses of total station. Mention the features of total station.(10 marks) 5 (a) What is transition curves? What are the requirements of an ideal transition curve. Enlist the objectives of providing transition curve and mention the different types of transion curves.(10 marks) 5 (b) A 3% vising gradient meels a 2% down gradients the vertical curve 200m long is to be used. The pegs are to be field at 20m interval. Calculate the elevation of the curve points by tangent correction method and calculate the staff readings required given that the height of collimation is 350m, RL of the apex is 350.0m and its chainges is 1000.0m(10 marks) 6 (a) What is GPS? What are tc advantages of space based positioning system and enlist the various application of GPS in surveging.(10 marks) 6 (b) Explain in brief
i) Auto level
ii) Objectives and advantages of GIS.
