Question

tions at the intersection points of a 15 m-square grid are given in the following figure. Using a The elevatioa of 2.5m, draw the contour map within this grid as follows: (26 marka t is the lowest contour line that appears on the map marts) is the highest contour line that appears on the map 2 mark What is t . List the other intermediate contour lines a . Calculate . Estimate te the locations of contour lines on grid line C3 to D3 only. 4 marks) and sketch the locations of all other contour lines.(5 marks) 0294.7 90._ 102.0 87.3 4 110.2-ㄧ-1107.3-一t103.3ー+100.1-ㅢ89.0 3 99.2 103.9 108.1 100+109992882 2 110.0 92.3 90.2 93.5 103.2 100.2 line profile leveling job is shown in the figure below (Total 17 mark e top figure label all stations with its chainage (stationing) coordinates in ground units for the s marks) e shows rod readings from level instruments in locations 1 &2.Use these readings to Note that Esn-10 m and Em: 9.063s marks) second figure The the table below ete the pipeline profile leveling calculations. ns Do the math check a mata Centerline of water pipeline Scale 1:2000 BM2 2510 A 1,600 o 2770 TP BM, Remarks FS HI Elevation IS BS Point 11.370m 10.000 m E 10.000 m 1.370 m 9.840 m 1.530 m 0+500 0+530 0+560 0+575 0+590 0+620 0+644 TP 0+674 0+698 0+728 0+752 0+799 0+829 9.700 1.670 m 9.640 m 9.470 m 9.320m 9.220 m 9.150 m 1.900 m 2.150 m 2.220 m 9.770 m 11.570 m 1.600 m 1.800 m 2.270 m 2.370 m 2.570 m 2.770 m 9.200 m 8.570 m 3.000 m 9.060 mE9.063 m 2.510 m 0.940 m 3.170 m Sum 0.940 m
