Elements and Performance Criteria

  1. Prepare for surveying computations.
  2. Execute computation tasks.
  3. Finalise computation tasks.

Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Appropriate persons must include at least one of the following:

client

experienced surveying colleague

qualified surveyor

supervisor or line manager.


Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit. The person must also accurately perform the following computations for two different surveying tasks:

calculate areas from bearings and distances or coordinates

calculate angles, distances, perimeter and area for simple and complex figures

set out data for simple horizontal curves

calculate surveying data required to set out the position of curves and structures

traverse calculations in east, north, misclose and adjustment calculations, and calculations based on adjusted coordinates

traverse types, include opening and closing on same point and different points of known coordinates.

While performing the above surveying computations, the person must:

communicate clearly with others to clarify work tasks and computational results

comply with organisational requirements and industry-accepted standards for:

systematically and legibly laying out computations

completing records and documentation

examine the computational results and verify the accuracy of results.
