5. During construction of a building, parts of the structure, including fabricated steelwork, heavy panels and many other components will remain standing prior to or after supporting parts are in place. What safety measure should be taken to prevent the structure from collapsing?

For prevention of the frame from collapsing and injury, temporary bracing should be in place.

6. Provide 2 examples of controls to mitigate risks associated with manual handling.

• Lifting of heavy weight that is above 25 kg should be done by 2 people.
• In lifting technique, workers should be trained.

7. What is the purpose of temporary fencing around construction sites?

Temporary fencing is an alternate to the permanent counterpart. Where there is an requirement of the fence on interim basis, it is needed for storage, public safety or security and crowd control

8. An extension lead is tagged with the label below. Is the lead safe to use? Why or why not?

No it is safe to use, because it is not tested till 2017

9. List 10 tools and equipment used to construct wall frames.

Following are the tools and equipment that is used to construct wall frames:

• Gloves
• Nail Gun
• Pencil
• Safety Glasses
• Tape Measure
• Hand Saw
• Circular Saw
• Spirit Level
• combination Square
• Ear muffs

10. The plans for a new building show one wall is 3150 millimetres long. The centre to centre spacing between each stud on the wall is to be 450 millimetres. Calculate how many spaces there will be.

3150/450=7

11. During the construction of a new home, the owner requests an additional wall to be built to divide a large room into two smaller rooms. This wall is to be 2400 mm high x 4350mm long, with one 820mm door. Wall plates are 90 x 45 MGP10, and the studs and noggins are 90 x 35 MGP10. Supply a timber list for this.

Material list

Wall plates 90*45-2/4.5

Studs 90*35 - 9/2.4 at 600 m centre

Noggins

12. Explain what ‘F Grading’ is and what it’s used for.

Grouping of timber is named for an F-grade. It characterises the strength for graded structure timber. In Mega Pascal, F stands for force.

13. When you're getting timber ready to put into a wall frame, you need to keep a close eye on the quality of each piece you handle, to make sure that it's up to the standard specified by the grading rules. List 4 reasons why a piece of timber may be rejected before it is put into the wall frame.

• Want and Wane
• Splits and Shake
• Wrong Grade
• bending or distortion

14. Which of the below would have a Safety Data Sheet?

15. What are wind loads and what effects do they have?

The force of wind blowing against the building leads in the production of stress in the walls and roofs. This kind of force is known as wind load. Application of horizontal force is the effect of wind loads. These forces are deled by the Australian Standard and is known as AS4055.

16. Label the wall frame members in the diagram.

17. To calculate the timber required for constructing wall frames, what measures will you need to obtain from the floor plan? List 4.

• Length of both top and bottom plate.
• Length as well as amount of noggins
• Length as well as amount of listed
• Stud’s height

18. Outline the 6 step procedure for setting out the plates in a wall frame.

• Working on the length of wall from the plates.
• Position of the studs, window, doors and wall junction to be marked.
• Brick storey rod to be made.
• Position of rod to be set out.
• Identification of plates with common notation.
• By using suggested notation, identify the plates.

19. What is the stud length for a finished ceiling level (FCL) of 2440mm, given the following factors: Top and bottom wall plates – 90mm x 45mm. Plasterboard ceiling 10mm sheet, 20mm allowance for frame settlement/shrinkage.

2440 – 90 = 2350

2350 + 10 + 20 =2380 mm

20. Describe the process for marking out stud positions on the wall plates for a single room bungalow, to be clad in weatherboards.

For external corners, mark the 3 studs.

21. What is a pattern stud, and what is its purpose?

Template for height of doors and windows is the pattern of stud.

22. Describe the correct 5 step process for correctly assembling a wall frame.

• Selection of wall plates
• Door, window and common studs to be marked.
• Lintel, trimmer, blocking and noggins are fixed to the place.
• Check diagonals.
• For all the frames and stacks, the process needs to be repeat.

23. Before standing up the frames, they are squared up, and the diagonal bracing is temporarily fixed. Why?

Allowing for the adjustment later.

24. How are wall frames joined at wall junctions, what reference points show their position, and how are the bottom plates fixed to the slab?

Blocking and nailed

Reference stud markings

Frame nailed to slab with concrete nails

25. Detail the correct preparation and procedure for erecting a wall frame.

• Checking of slab for the correct size and square.
• Stacking of frames in correct order for installation.
• Assembling of the frame.

26. Standing up of the fabricated wall frame presents the risk of collapse or falling over during construction. Describe a safe method to erect a frame, and what measures can be taken to prevent collapse during construction, and how are the frames held in a true and plumb position in readiness for the ceiling/roof frame or truss installation?

2 man lift and fix temporary bracing

27. When laying out the wall plates, it is good practice to use the best quality timber for the top plate, and the lesser quality for the bottom plate. Why is this?

Straightening of the wall is made easy.

28. What is the recommended 3 step process for straitening studs?

• In a hollow side, make a saw cut to a depthof half the stud.
• Nailing a cleat to the face of the stud.

29. Write a checklist for ensuring the quality of the frame members and the frame as a whole. List 14 items that must be checked.                        

• Walls for plumb, square, straight and level
• Top and bottom plates fixed to studs
• Bracing and tie downs in place
• Noggings at correct centres
• Corner blocking must be checked
• Walls fixed and tied together needs to be checked
• Room sizes and height are to plan must be checked
• Check the Window and door openings correct size
• Jamb studs to all openings should be checked
• Concentrated load bearing studs needs to be checked
• Lintel in place should be checked
• Checking of Blocking under studs as required
• Check for excessive notching
• Notching out for plumbing should be checked

30. How should you leave the work site at the end of the day? In your answer, consider tools, materials and waste.

When the work site is left, it should be free from danger and it should be clean as well.
