Remove trees in confined spaces

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Elements and Performance Criteria



1. Prepare for tree removal

1.1. Site and tree hazards are identified, risks assessed and suitable controls implemented.

1.2. Tree is inspected to ensure the appropriate removal method is planned that confirms the risk controls selected and is in accordance with the documented low risk work methods.

1.3. Access to site is determined and approved by owner/site management.

1.4. Site preparations include notification of local residents and authorities where necessary.

1.5. Signage, barriers, warning devices and traffic management equipment are erected as necessary.

1.6. The drop zone is determined and communicated to all personnel.

1.7. Assets, property and vegetation related to work zone activities are protected, relocated, and/or secured from potential damage during tree removal.

1.8. Tools, equipment and machinery necessary to implement tree removal are selected, prepared, checked and used according to documented guidelines and manufacturer recommendations.

2. Implement dismantling of trees

2.1. Suspended, wind thrown or damaged trees are stabilised to ensure trunk movement does not occur, and are brought down safely and efficiently according to documented low risk work methods.

2.2. Mass of tree sections is calculated and does not exceed the safe working limit of equipment.

2.3. Branches and trunk sections are dismantled using the 'cut and drop' method, and cut and lowered by ropes and other lowering devices according to documented low risk work methods.

2.4. Dismantling techniques are employed to ensure branches and trunk sections fall or are lowered safely into the determined drop zone, with no damage to property and equipment or injury to personnel.

2.5. Directional felling techniques are employed to ensure trunk of dismantled tree falls safely into the determined drop zone with no damage to property and equipment or injury to personnel.

2.6. Friction devices are used and controlled where required by documented low risk work methods.

2.7. Elevated work platforms are used and controlled where required by documented low risk work methods.

3. Complete tree removal

3.1. Felled trunks are trimmed to manoeuvrable lengths without injury to the operator.

3.2. Sufficient material is removed from the stump to prevent re-growth and/or the stump is treated to prevent regrowth.

3.3. Plant material and debris is processed and removed from site according to documented guidelines.

3.4. Tools, equipment and machinery are cleaned, checked, replaced if faulty or worn, and stored according to documented guidelines and manufacturer recommendations.

3.5. Completed tree removal is recorded and communicated to management and/or the client.
