Q5 (a) Assume that the circular curve will be used at a PI where I = 8°24'. Assume that the station of the PI is 6 + 427.464, and that terrain condition require a minimum radius of 900 m. Calculate the PC (T1) and PT (T2) stationing, and other defining elements of the curve. Also compute notes for staking the curve using 20 m increments. (10 marks) (b) Figure Q5(b) shows all points observed using the levelling equipment with grid method. The reduced level values for each point are given in Table 5(b). Each point will be dug to same level of 10 m above datum. Determine the mean value and volume using Triangle and Square methods. (10 marks)
