A Survey line 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 bearing of AD and DC are 38°45′ & 278°45′ respectively and the chainage at A is 862 m. Find the chainage at B.

Explain with neat sketches for different accessories used in plane table survey.

The followings bearings were observed while conducting a close traverse with a compass in a place where local attraction was suspected. At what stations do you suspect local attraction? Find the corrected bearings of the lines and the included angles.

A river is flowing from west to east. For determining the width of the river, two points C and D are selected on the southern bank such that the distance CD = 150m. Points C is west wards. The bearings at a tree ‘Q’ on the northern bank are observed to be 45° and 335° respectively from C and D. Calculate the width of the river.

Reciprocal leveling was done between two points A and B situated on the opposite sides of a valley 750m wide. Determine the difference in level between A and B and the amount of collimation error if any.

Explain the methods of contour plotting.

The following consecutive readings were taken with a dumpy level and 4m leveling staff on a continuously sloping ground at 30m intervals. The RL of starting point was 80.750m. Rule out a page of the level book, carry out reduction of heights by rise and fall method, and determine the gradient of the line joining the first and last point.

Explain when reciprocal levelling is done? Describe the method along with a neat sketch.

Calculate the area between the chain line and the boundary using offset readings taken at specified chainage points.

At a station, a trench was measured and found to be 1m wide and 1.25m deep. At the next station 10m away from the first one it was 1.1m wide and 2.7m deep. Determine the volume of earthwork between two stations.

Calculate the volume enclosed between chainage 1000m and 1120m by the prismoidal and end area formulae given the cross-sectional areas at different sections.

Compute the area between the chain line, the irregular boundary line and the end of offsets by: i) mid ordinate rule, ii) the average–ordinate rule, iii) the trapezoidal rule, iv) Simpson’s rule.

Explain briefly the different methods of traversing with a theodolite.

Describe the process of permanent adjustment in a transit theodolite.

A tacheometer was set up at a station C. Calculate the horizontal distance CD and RL of D.

Explain the construction of a theodolite instrument with a neat sketch.

Two tangents intersect at a chainage of 1190m, the deflection angle being 36°. Compute all the data necessary to set out a curve of radius 300m by offset from long chord produced.

Explain briefly the applications of GIS and GPS in surveying.

A Tacheometer was kept at a station P and observations were made to a stadia rod kept at station Q. The reading on a staff held at a BM of RL 110.95m was 2.135m. Find the distance PQ and the RL of point P.

Explain with neat sketch the construction of Electronic distance meter. Elaborate its uses in computation of measurements.
