Consider the traverse ABCDE as shown below. AB is the datum/reference direction of the traverse with Known coordinates for A and B as given below: A (E=327682.209, N=5813380.144, Z=20.467) and B(E: 327882.209, N:5813116.199, Z=23.779) where Z is the elevation or RL value of the point. Internal angles and horizontal distances are measured using a Total Station as tabulated below: Angle @ Direction Measured (unadjusted) distances (m) A | __ Measured (unadjusted) Angles 152° 54’30” 111° 11’15” 57° 55’55” 163° 32′ 35″ 53° 26′ 10″ 435.160 486.920 361.860 354.580 DE EA Not into scale 1. Work out the direction (whole circle bearing), length and grade of AB using the coordinates of A and B https:l/en.wikipedia og/wik Grade (slope) 2. Using the computed direction for AB and measured internal angles as tabulated above, work out the bearings of all other directions (i.e. BC, CD, DE, EA and again AB to check). (Hint: refer to the bearings of the next direction in Lecture 3). 3. Close the traverse using Bowditch adjustment and compute adjusted bearings and distances for all traverse sides. 4. Rotate the traverse so that the direction of the reference line AB is unchanged before and after Bowditch adjustment. 5. Work out the coordinates of traverse corner points after rotation in Q4. Note: When possible and suitable tabulate the data and computations. 3. Close the traverse using Bowditch adjustment and compute adjusted bearings and distances for all traverse sides.

It is intended to construct a temporary access road from A to B and then to C, D, and E with a constant grade of 1m rise per 100m run. Work out the grade from E to A upon the construction of the access road.
