A circular curve of radius 750 m is to connect two straights, which deflect through an angle of 14°36'12". The through chainage of the intersection point is 2319.87 m. The centre line of the curve is to be set out by the tangential angles method using a total station and a pole-mounted reflector. Pegs are required on the centre line at exact 25 m multiples of through chainage. (i) Calculate the through chainage of the two tangent points (ii) Draw up a table listing the data required to set out the curve from the entry tangent point (iii) Briefly describe how the centre line is set out.
