Performance Evidence

Accurately select, set and use laser levelling devices to obtain and interpret specified measurements

Maintain and store laser levelling devices

Read, interpret and follow information on standard operating procedures, manufacturer recommendations, drawings and other applicable reference documents

Set up levelling equipment and take levelling measurements and perform necessary calculations

Confirm accuracy of the readings taken, including set up and movement of laser levelling device in two locations

Level and align a range of glass window and door components for installation in buildings

Confirm work requirements and specifications and the report work outcomes and problems and follow safety procedures

Avoid backtracking, work flow interruptions or wastage

Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
