CPCCCM3006 Carry out levelling operations

Modification History

Release 1.

This version first released with CPC Construction, Plumbing and Services Training Package Version 2.

Revised unit of competency. Replaces superseded equivalent unit CPCCCA3023A Carry out levelling operations.

Application

This unit of competency specifies the outcomes required to carry out levelling operations, using the rise and fall method and the height of collimation method, to establish correct and accurate set-out of buildings and components. It includes the set-up, testing and use of levelling devices and undertaking closed and open traverses using a range of levelling equipment. It also includes calculating distances using stadia lines.

The unit supports workers in the construction industry who use a variety of commonly used levelling devices when working with others and as a member of a team to establish accurate set-out data for a range of construction projects. It applies to levelling operations on residential and commercial work sites in new construction, renovation or refurbishment, and maintenance projects.

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

Elements and Performance Criteria

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.	Plan and prepare.	1.1.	Job requirements are obtained, confirmed with relevant personnel, and applied to planning.
1.2.	Work site is inspected, and conditions and hazards are identified and reported as required.
1.3.	Health and safety requirements for levelling operations at the work site are confirmed and applied to planning.
1.4.	Levelling tools and equipment required for job are selected and checked for serviceability, and faults are rectified or reported before starting work.
1.5.	Team roles and verbal and non-verbal communication signals are confirmed, as required.
2.	Carry out levelling procedures using rise and fall method.	2.1.	Instrument is accurately set up and tested for operation before commencing levelling activities.
2.2.	Datum point is set up or located.
2.3.	Readings are taken from the datum and at nominated or selected stations according to project specifications.
2.4.	Backsights, intermediate sights and foresights are identified and levels are booked.
2.5.	Instrument is transferred to another location, process is repeated, and change station is recorded in field book.
2.6.	Reduced levels for all stations are calculated using rise and fall method of calculation, and accuracy of field book recordings is checked using the three check method.
3.	Carry out levelling procedures using height of collimation method.	3.1.	Instrument is accurately set up and operation and tolerances are checked.
3.2	Datum point is set up or located.
3.3.	Level readings are taken to datum, and the height of collimation is established.
3.4.	Readings are taken at nominated or selected stations according to project specifications.
3.5.	Instrument is transferred to another location, new height of collimation is established, and change station is recorded in field book.
3.6.	Reduced levels are calculated using height of instrument method.
3.7.	Reduced levels for all stations are identified from calculations and heights and levels are recorded.
3.8.	Accuracy of readings is established using height of collimation method of calculation and three check method.
4.	Calculate distances using stadia lines.	4.1.	Distances are calculated from instrument to stations using staff, stadia lines, and identified factor of levelling instrument.
4.2.	Readings and distances are recorded.
5.	Clean up.	5.1.	Tools and equipment are cleaned, checked and stored.
5.2.	Levelling devices are maintained and stored according to manufacturer recommendations and standard work practices.
