The following level data are listed in order of observation, with turning points in parentheses. The first staff reading was taken unto BM25, 155.628 mAMSL, and the last reading was taken to TBM3 with known elevation of 156.055 mAMSL. 1.905, 2.321, 1.675, (2.001, 2.957), (2.198, 3.029). 0.758, 1.225, 2.476, 3.041, (2.457, 1.160), -3.985, 1.015, 3.994, 3.652, 1.965 (a) Produce a realistic sketch to illustrate measurements taken in the level circuit. (5 marks) (b) Tabulate the data in a typical level table and use the Height of Collimation method to calculate reduced levels for all staff positions. Show all booking and computation checks. (12 marks) (c) The negative staff reading was obtained from an overhead bridge and the staff reading following was taken on the road below the bridge. Determine mathematically, if a truck stacked to 4.500 m will be able to pass, uninterrupted, the underside of the bridge.
