Question 5 As the Lead Surveyor for the AIT junction-Red Top road project. This project comprises the feasibility study, design and construction of 30.35 km of road rehabilitation. The following consecutive readings were taken with Automatic level on 5 m leveling staff at 20m intervals: 2.742m, 2.7m, 1.29m, 0.71m, 2.64m, 2.25m, 1.90m, 1.57m, 1.23m, 0.823m, 0.27m 2.87m, 2.73m, 2.21m, 1.33m, 0.87m, 0.07m, 3.48m, 3.35m, 2,65, 1.665, 0.725, 0.285m, 4.82m, 4.15m, 3.11m, 22.355m, 1.521m, 0.441m 3.135m, 2.42m, 1.77m, 1.02m, 0.395m, 2.06m, 1.89m, 1.595m ,1.329m, 1.083m, 0.785m, 0.525m, 0.35m The readings underlined are fore sights. If the RL of the initial station was 100.30m above datum. Draw up a level book page and reduce the levels by the height of instrument method. a) Calculate elevations of the points. Major Topic 3 - Leveling b) If the reduced level of the last point is 100.200m, adjust the levels and is the misclose allowable. c) Major Topic 4 - Booking and Reducing the level Determine the gradient of AB. Major Topic 2 - Distance Measurement and Errors. EV 9 CR EV 7 4
