Assessment details
The 1000 marks to be allocated in this course are to be divided in accordance with the Course
specifications. Take particular note of the ‘Assessment details’ and ‘Other requirements’
sections.
The assessable assignments are contained in this introductory material. The dates on which
they are due are given on the assignments and in the course specifications. These assignments
should be done unaided after study of the relevant material and submitted to the USQ on or
before the due date (refer assignment extension policy statement).
The Faculty of Health, Engineering and Sciences does not accept any assignment work
submitted by fax or email.
Assignment / Exams
In the assignment and exams be sure to lay your working out clearly, and apply the necessary
checks to ensure your answer is logical and correct. In surveying, great emphasis is given to
obtaining the correct solution as well as using the correct method. This is important when you
consider that survey supplied data is the BASE from which professional engineers apply, or
build upon, their data.
As Engineers you will be regarded as professionals, as engineering students we expect you to
show this professionalism in your studies.

Question 1 (70 marks)
a) An Engineer traversed in a loop around four stations (A, B, C and D) with a Total Station
as illustrated in the following diagram. The starting point is Station A with a known bearing
(3500 30’ 00”) to a far station S1. The coordinates of point A (2500.000m E and 1500.000m
N) is known and the observed angles and measured distances are given in the diagram
below. Compute the bearings of lines AB, BC, CD & DA and coordinates of stations B, C
and D. Compute the misclose in ΔE and ΔN, comment on your linear misclose (bearing
and distance) and the misclose ratio. Show all workings to four decimal places and checks.
