Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Measure linear distances on site using building and basic surveying equipment. |
1.1. Areas and volumes of regular shapes and figures are calculated. 1.2. Distances are measured accurately, independent of site characteristics and measurement methods, using basic surveying equipment . 1.3. Distances are measured on building sites within a tolerance of 1mm error in 4.0m (1:4000) or without error. 1.4. Overall distances are calculated from field data without error. 1.5. Slope corrections are recorded accurately. |
2. Carry out a closed level transverse procedure using the rise and fall recording method. |
2.1. Levelling equipment is inspected for damage, wear and serviceability. 2.2. Set-up steps are performed and instruments made ready for use without error. 2.3. Instruments are checked for accuracy and adjusted (where possible) within 3mm over 60 metres using the two peg test. 2.4. Closed level traverse procedure is completed with a minimum of 15 points, including an inverted reading, with a minimum of 5 change points all within a closing tolerance of 10mm. 2.5. Data of traverse is correctly recorded and extended including mathematical column checks by use of the rise and fall method. |
3. Perform grid surveys for contour purposes. |
3.1. Site identification for site surveying and setting out procedures is established and all survey pegs are located without error. 3.2. Grid distances are determined and grid is pegged correctly. 3.3. Site detail that may effect building operation is recorded without error. 3.4. Reduced levels of all grid points are determined from a close performed onto the bench mark to within 10mm, without error. 3.5. Contour lines are plotted on the site plan at intervals appropriate to the site with longitudinal and cross sections pegged and measured as nominated within 100mm. Sections are plotted to scale without error. 3.6. Grades of line are determined within a 0.5% tolerance and expressed as percentage, rise to run ratio, or degrees. 3.7. Cut and fill volumes of soil are calculated from site plan using contour lines for determining reduced levels (RLs) within 5% tolerance. |
4. Set out T-shaped or L-shaped buildings on a selected site with minimal profiles. |
4.1. Site information is identified from site plan and dimensions are checked on plan drawings without error. 4.2. Site is identified and survey pegs are measured to ensure correct identification occurs before pilot pegs are positioned within 50mm of true location of the squared building dimensions. 4.3. Profile pegs are set up on site at a working distance from pilot pegs and parallel to pilot line. 4.4. Profile boards are fixed to pegs and level within 5mm and 15mm of each other. 4.5. Profiles are set out on steep slopes accurately. |
5. Set up and use levelling devices to determine horizontal and vertical angles. |
5.1. Basic tests on levelling devices' accuracy/adjustment are performed to manufacturer specifications. 5.2. Temporary adjustments to set up levelling devices are carried out to standard operating procedures. 5.3. Levelling devices are used to determine (read) both horizontal and vertical angles to an accuracy of 20 seconds. 5.4. Levelling devices are used to set our horizontal angles to an accuracy of 20 seconds. 5.5. Site is set out to specifications using a typical levelling device and tape. |
6. Identify suitability of levelling and surveying equipment for large building projects. |
6.1. Differences between various types of specialised surveying equipment are researched and recorded. 6.2. Equipment is used to control set out and vertical is identified. 6.3. Basic differences in survey control and set out between frame and concrete multi-storey buildings is outlined. 6.4. Survey of each level for vertical accuracy of 10mm is carried out using two levelling devices. |
7. Compute coordinates, bearings and distances related to grids and general set out work on large building sites. |
7.1. Angular relationship between different bearings (whole circle) is demonstrated and bearings from angles and fixed lines are determined. 7.2. Bearing and distance between two sets of coordinates (north and east) are calculated. 7.3. Coordinates of a point, given the bearing and distance from a point with known coordinates, are calculated. 7.4. Offsets from a coordinated point, given the bearing and distance from a point with known coordinates, are determined. 7.5. Information necessary to set out a structure, or part thereof, using a site plan with positions fixed by a mixture of bearings and distances, offsets and coordinates is calculated. |
Evaluate documents and plans incorporated in land titles. |
7.6. Documents that make up a land title are listed and their relationship to each other outlined according to relevant government legislation. 7.7. Different restrictions on the use of land title and restricted development are illustrated. 7.8. Building covenants and statutory bodies responsible are identified. 7.9. Restrictions stated in legislation that regulate setbacks for residential buildings are identified and differentiated. |

Evidence Guide
EVIDENCE GUIDE |
|
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. |
|
Overview of assessment |
This unit of competency could be assessed in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
|
Context of and specific resources for assessment |
This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints. Assessment of essential underpinning knowledge will usually be conducted in an off-site context. Assessment is to comply with relevant regulatory or Australian standards' requirements. Resource implications for assessment include:
Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support. |
Method of assessment |
Assessment methods must:
Validity and sufficiency of evidence requires that:
Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed. Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff. |
