a) compute all elevations

b) Complete the arithmetic check

c)Determine the error of closure

d) Is the error acceptable? If yes, adjust the elevations.

BM Zulu has an elevation of 510.36 ft. You wish to establish the elevation of a new benchmark to be known as BM Boracho. A vertical control survey was completed. Use the sketch below to complete the field notes, as follows: a) Compute all elevations, b) Complete the arithmetic check, c) Determine the error of closure, d) Is this error acceptable? If yes, adjust the elevations. Assumptions: The distances between points are equal. 1.25 BS BM Zula 1.10 FS BM Zula Allowable error (mm) = 2*(No. of Turning Point). 7.86 FS 1.35 6.54 BS TP1 7.52 BS 1.31 FS TP6 FS 2.08 5.36 6.81 BS BS FS A TP2 TP5 1.75 5.29 FS BS. 1.93 7.98 BS FS TP3 1.29 FS TP4 BM Boracho 7.06 BS BM Boracho.
