1. Attempt all questions.

2. Make suitable assumptions wherever necessary.

3. Figures to the right indicate full marks.

Q.1 (a) Enlist various methods of plane tabling & explain with sketch any Two methods.

(b) Explain :- Methods of taking horizontal angles with vernier transit Theodolite.

Q.2 (a) Why are curves provided? State various types of curves with sketch.

Draw the neat sketch of simple circular curve showing various elements of it.

(b) How will you adjust closing error of traverse by graphical method & by Transit rule?


(b) Following are the bearings and length of a Traverse ABCD. Find out

closing error of traverse.


Length(m) 105.8 142.5 188.8 188.9

Bearing 319015’ 51030’ 131045’ 256045’

Q.3 (a) Draw the sketch of following & write their function

(i) Alidade (ii) U-Fork (iii) Trough compass

(b) Why are transition and vertical curves provided? What are the

advantages & requirements of an ideal transition curve?


Q.3 (a) Explain the procedure for evaluating missing quantities in a closed traverse.

(b) Write method of setting out a culvert.

Q.4 (a) Enlist various methods of setting out simple circular curve. Also

explain one Theodolite method of setting out a simple circular curve.

(b) Derive an expression for ‘D’ & ‘h’ in case of Trigonometric leveling

when base of object is inaccessible, Instrument station in same

vertical plane with the elevated object for (i) Instrument axes at

same level (ii) Instrument axes at different levels


Q. 4 (a) To determine the height of a chimney, a Theodolite was kept at Two

stations I1 & I2 200m apart. I1 being nearer to the chimney. The

reading at the BM of RL 1020.375m were 1.35m from station I1 &

2.15 from I2. The vertical angles to the top of the chimney where

19030’ & 8015’ from stations I1 & I2 respectively. Find the horizontal

distance & RL of the top of the chimney.


(b) Two straights AB & BC intersect at chainage (375 + 12), the angle

of deflection being 1100. Calculate the chainage of the tangent points

of a right handed circular curve of 400m radius. Chain was used of


Q.5 (a) Enlist equipments needed for a soundings, also explain with sketch

station pointer.


(b) A road embankment is 8m wide & 200m in length at the formation

level, with a side slope of 1.5(H) :1(V). The embankment has a

rising gradient of 1 in 100m. The ground levels at every 50m along

the centre line are as follows

Distance (m) 0 50 100 150 200

Ground RL (m) 164.5 165.2 166.8 167 167.2

Take formation level of zero chainage is 166m calculate the volume

of earth work by Trapezoidal rule & Prismoidal rule.
