Perform surveying computations

Assessment tool

Version 1.0
Issue Date: April 2024


This unit of competency specifies the outcomes required to perform surveying computations in a plane coordinate system. Computations involve simple and complex figures with regular and irregular sides, and computations for traverses, angles, bearings, coordinates, perimeter and area. Computations include simple horizontal curves and horizontal set-out data for curves. Specialised software applications are routinely used.

The unit supports those who work in support positions in a surveying team to conduct surveying and mapping tasks.

No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions.

1.

Prepare for surveying computations.

1.1.

Task requirements are identified in consultation with appropriate persons.

1.2.

Computational methods are identified according to industry and organisational procedures.

1.3.

Computational equipment is selected according to task and organisational requirements.

2.

Execute computation tasks.

2.1.

Computations are performed on coordinates of a simple closed traverse using computational equipment, and missing elements and coordinates are adjusted and computed.

2.2.

Traverse information is reduced and adjustments are performed according to industry-accepted standards and task requirements.

2.3.

Computations are performed on all elements of simple circular curves, and missing elements are solved according to standards and organisational requirements.

3.

Finalise computation tasks.

3.1.

Data and computations are checked to ensure accuracy according to standards and task requirements.

3.2.

Computations are finalised and recorded according to organisational requirements.

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.

A person demonstrating competency in this unit must demonstrate knowledge of:

common computational terms used in surveying

industry-accepted methods for performing surveying computations in a plane coordinate system

methods for checking accuracy of computations to identify errors and solve problems

methods for computing basic traverse data

organisational procedures for completing surveying records and documentation.

The following must be present and available to learners during assessment activities:

equipment:

scientific or programmable calculator or a software application that includes surveying calculations

specifications:

task specifications

organisational policies, procedures and documentation relating to work tasks

relationships with team members and supervisor:

working in a team.

Timeframe:

as specified by the task and organisational requirements.

Assessor requirements

As a minimum, assessors must satisfy the assessor requirements in the Standards for Registered Training Organisations (RTOs) current at the time of assessment.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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.

Assessor requirements

As a minimum, assessors must satisfy the assessor requirements in the Standards for Registered Training Organisations (RTOs) current at the time of assessment.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
