Fell trees with advanced techniques

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. Trees are assessed for size, structural defects, weight distribution, spread/width, wind loading and canopy.

1.2. The fall site is assessed considering wind speed and direction, topography, safe fall zone, exclusion zone, any potential danger to the public or property, and environmental implications.

1.3. Tools, equipment and machinery are selected according to appropriate removal methods.

1.4. Pre-operational and safety checks are carried out on tools, equipment and machinery according to manufacturers specifications and enterprise guidelines.

1.5. OHS hazards are identified, risks assessed and risk controls are implemented.

1.6. Risk controls selected determine work method to cut and drop, or use rigging techniques.

1.7. Suitable safety equipment and Personal Protective Equipment (PPE) is selected, used and maintained.

2. Coordinate site preparation

2.1. A safe fall zone and exclusion zone are determined considering tree characteristics, degree of lean of tree, and site, environmental, and safety assessments.

2.2. A planned escape route, noting debris and other potential hazards is determined.

2.3. Fall zone and escape route are cleared and surrounding features/structures are protected from damage.

2.4. Exclusion zone is identified, appropriate safety barriers erected and safety procedures implemented and monitored.

3. Dismantle branches

3.1. Weights of tree branches are ascertained so that they do not exceed the safe working limit of equipment.

3.2. Branches are dismantled using the "cut and drop" method, or cut and lowered by ropes in accordance with accepted rigging techniques.

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

4. Dismantle tree

4.1. A safety lanyard and climbing spurs are used to ascend tree to perform sectional felling.

4.2. An elevated platform is used for access to assist sectional felling.

4.3. Sections are cut and thrown using a directional scarf and back cut with an accepted industry method.

4.4. Sections are cut and dropped using a horizontal cut and appropriate hinge wood.

4.5. A pull rope is used to control fall of tree sections.

4.6. Industry standard hitches and knots are used in rope lowering of cut tree sections.

5. Fell wind thrown and suspended trees

5.1. The risk potential of wind thrown or suspended tree is assessed.

5.2. Safe work methods which apply to the removal of wind thrown or suspended trees are adopted.

5.3. Hand or power winches are used to pull out the suspended tree as necessary.

5.4. The root system of a wind thrown tree lying on the ground is propped.

5.5. Wind thrown tree is crosscut in correct position to reduce trunk movement and prepare it for removal.

6. Complete felling operations

6.1. Felled trunks and branches are crosscut and trimmed to manoeuvrable lengths ready for disposal.

6.2. The site is cleared of trunk, branches and tree debris.

6.3. Timber disposal methods and equipment are used in accordance with the manufacturer's specifications and documented low risk work procedures.
