Quantity Calculation Activity (Numeracy - Foundation Skill)
As part of Activity 4 Template 1, calculate the following from the supplied roof plan and truss layout. Show your working. This activity provides direct evidence of the Numeracy Foundation Skill.
Calculate the total square metreage of the roof for the timber zone.
Calculate the total square metreage of the roof for the steel zone.
Calculate the number of trusses required at the design centre-to-centre spacing.
Calculate the linear metres of bracing material required.

Activity 1: Safe Work Procedures (SWPs) Sign-Off
Students are to check the tools and equipment, review the physical worksite, attend a tool-box meeting, review the SWPs and complete and sign-off the SWPs form given as Appendix C.Once students have reviewed all relevant information, they are to sign off the SWPs form to confirm their understanding.
Note:
The SWPs are provided as Appendix C to this assessment.
The student must review the SWPs and complete and sign-off the SWPs form.
Activity 2: Job Hazard Analysis (JHA) to identify hazards and control hazards
To perform this activity, the trainer/assessor shall show the required tools and equipment and the work location to each student so that they are able to identify potential hazards and consider adequate control measures.
The purpose of conducting Job Hazard Analysis (JHA) is to inspect work site, locate services, assess hazards and apply risk controls, including required signage and barricades.
Students are to review the physical worksite and tools and equipment, attend a tool-box meeting, review the instructions manual and complete the Job Hazard Analysis (JHA) form/checklist on the following page. The student must place a "√" in the checkbox if the hazard listed is relevant and leave it blank/empty if it is not relevant. If the student identifies any hazards, not on the checklist, they must add them to one of the blank spaces available in the checklist. Students must write up the control measures they think should be implemented. If the students think there are no control measures required, they must write "not applicable" in the form as any blank boxes will be marked as unsatisfactory.
Activity 3: Record of Tool-Box Meeting
The trainer/assessor, acting as the worksite supervisor, will run a tool-box meeting for students. The students are to listen carefully to the information provided and then fill out the "Record Tool-Box Meeting" form below. The student must place a "√" against each item they think the Supervisor has covered. The student must place an "X" against any item that is not covered. If the Supervisor (trainer) discusses an item that is not included on the form, the student must add a comment in the "Comment/Discussion" section at the bottom of the form to briefly identify what was discussed.
If the student thinks there were no additional items discussed, be sure to write "not applicable" in the form as any blank boxes will be marked as unsatisfactory.
The student will be given time to fill out the "Record Toolbox Meeting" in the classroom after they complete the tool-box meeting. Students are allowed to take the "Record Toolbox Meeting" form with them to the tool-box meeting.
At the conclusion of the meeting, the trainer/assessor will ask each student to repeat or paraphrase one item from the list of items. The student will need to respond verbally by summarising their understanding of what was said about that specific item. This also provides the opportunity for the student to demonstrate their verbal communication with the rest of the group.
