Table Q2 show the levelling data obtained from levelling fieldwork carry out by surveyor to
transfer reduce level from BM A (with actual RL= PP.PP m) to TBM 1 and the levelling end (Close)
at BM B (with actual RL = QQ.QQQ m). If total distance from BM A to BM B is 350m. Applying
height of plane collimation (HPC) calculation method, perform arithmetic and accuracy
verification, correction and calculate final reduced level. Then determine gradient between BM A
and BM B?
