Perform advanced surveying computations

Assessment tool

Version 1.0
Issue Date: April 2024

This unit of competency specifies the outcomes required to perform advanced surveying computations to solve from a range of surveying and basic engineering-related problems. The unit covers applying mathematical concepts, computations and conversions relating to algebra, statistics, geometry and trigonometry. It also covers solving a range of surveying problems to identify errors and missing elements, and make necessary adjustments to computations. It requires the ability to analyse and evaluate spatial data as the basis for performing computations.

The unit supports those who work under limited supervision in a surveying team.

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.	Standards in relation to accuracy and tolerances are identified according to organisational requirements.
		1.3.	Computational equipment is selected according to task and organisational requirements.

2.	Solve advanced computation problems.	2.1.	Computations are performed on the coordinates of a traverse using computational equipment, and missing elements and coordinates are adjusted and computed.
		2.2.	Traverse information is reduced according to standards and task requirements.
		2.3.	Problems involving linear figures of parallel, constant or different width are identified and solved according to standards.
		2.4.	Road intersections involving different road widths are solved according to standards.
		2.5.	Computations are performed to maintain areas of closed figures according to industry-accepted standards.
		2.6.	Computations are performed on all elements of complex circular and reverse curves, and missing elements are solved according to industry-accepted standards.

3.	Finalise computations.	3.1.	Measurements and computations are checked to ensure accuracy according to industry-accepted standards and task requirements, and are adjusted as required.
	Finalise computations.	3.2.	Computations are finalised and recorded according to organisational requirements.
