  • Second is Back filled, and
  • The last is, Should be level

  1. If bearer material is to be cut or lengths need to be joined, where should these cuts or joins be located?

Over a support, joints should be located 

  1. In 6 steps, documents the process to lay bearers?
  • On tops of base walls or piers, Fit ant capping DPC or required flashings 
  • Check that the tops of base walls columns or piers are terminating at the correct heights
  • Lay bearers or saw stools and square their ends . Prepare end joint scarfs or halving if required
  • Mark off the positions where any anchor bolts pass through the bearers and drill holes
  • For checking that the top edge is in alignment, Lay the outside bearers 
  • Between the two bearers stretch the sting lines, and install the intermediate bearers to the string line.

  1. What is placed between timber members such as bearers and brick piers?

A damp proof course (DPC)

  1. Describe the process to fix a timber bearer to a concrete stump?

Through following process timber bearer can be fixed 

  • It can be fixed through Drill hole
  • Install ant cap will also help in fixing it 
  • Another way of fixing timer bearer for concrete stump is Insert rod

  • Joist positions on the bearers needs to be marked 
  • Joists and fit blocking should be fixed 
  • Level the joists
  • Place joists in position for fixing

  1. Timber members, such as bearers and joists, need to be selected for length and straightness. How should ‘bows’ in these members be treated?

In order to level them out straight, the bows should face up

  1. How can joists be fastened? Identify 3 ways.

Joist can be fastened in following three ways:

  • Joist straps 
  • Triple grips 
  • Skew nailed

  1. What is a ‘deep joist’?

Where the height of joist exceeds 4 times the width. It should be restrained from rolling over. Between the joist spacing, the blocking is required.

  1. List 2 strutting methods.

The 2 strutting methods are: 

  • One is Herringbone strutting, and 
  • Second is Solid Blocking

  1. How is the length and bevel of herringbone struts determined?

Herringbone struts from the joists tops are fixed 12mm down and 12mm up from the bottoms. For obtaining the length and bevel, measure the depth of the joist and deduct the above. The spacing between the joists on the lower edge of the body should be marked.

Timer or metal beam is a trimmer, in light-frame construction, that is used in creation of an opening around a stairwell or chimney. It is installed parallel to the primary floor. 

  1. What is the difference between platform flooring and cut-in flooring?
  • PLATFORM FLOORING: it is a system where the joists are fastened into position and flooring is fitting. It is a common method as it is easier and safer.
  • CUT-IN FLOORING: it involves the construction of floor frame and placement of wall framing on the joists.

  1. There are 2 main types of flooring: sheet flooring and strip flooring. Briefly describe the types of materials used in each and how they are fastened?

There are different kinds of flooring in different areas. It is used where the surface is the desired finish. It is costly to install. 

  1. How do you calculate the quantity of flooring required?

The floor quantity is calculated, depending on whether flooring is sheet. It can be order by the square meter. The supplier will work out the number of sheets that are based on the available sizes of the sheets.

  1. In 4 steps. Detail the procedure to lay sheet flooring?
  • joists tops true and it should be checked
  • Spring a chalk line across the joist tops and through the length of the floor one sheet width in from one edge.
  • The sheet should lay the correct side up in alignment with the chalk line.
  • Sheet excess may overheat on one side and edge. 

  1. Detail 3 step procedure to xlay T&G flooring?
  • Between the first board and the wall, there should be a gap of 10 mm. The first row of board should be fastened to a chalk line driving nails. 
  • Against the first board, four or five row of board should be laid. Ensure that the before the nailing the boards are tight.  
  • When laying the last board on a cut-in floor, between the board and the wall plate there should be a gap of 10mm by using the pinch bar. By using a pinch bar the last board should be tighten.
