Explanation / Answer

12. c) Elevation = elevation (BM) + BS (BM)) - FS (at 1+62.5) = 100 + 11.63 - 10.6 = 101.03'

13. a) Elevation of TP1 = HI - FS(at TP1) = 111.63 - 9.27 = 102.36'

14. b)

HI = Elev (TP1) + BS at TP1 = 102.36 + 5.39 = 107.75'

Measured Elevation of BM2 = HI - FS at BM2 = 107.75' - 8,73 = 99.02

Error of closure = 99.02 - 99.00 = 0.02

15. e)

Elevation = HI - FS = 107.75 - 4.9 = 102.85'
