Question 2 RL PP.PPP (m) RL QQ.QQQ (m) 65.732 64.939 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.PPP 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 %3D and BM B? Point BS IS FS HPC RL Corr.

Instruments for Surveying

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for measuring horizontal angle, vertical and sloping angle, which are very useful for giving accurate and precise measurement.
