2 (a) Describe the principle of techeometry and differentiate between fixed hair method and movable hair method of techeometry.
8 M
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°

3 (a) What is transition curves? Why it is provided, explain different types of transition curve.
10 M
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 M

4 (a) What do you understand by setting out work? Explain in detail the procedure for setting out work for a building.
