Q1:

Answer :

Damp proofing is the method to protect the building from moisture and water penetrating into the walls which can cause damage to the building and rotting. It can be caused by – heavy rain, low quality construction material and ground moisture.


Damp proofing is done to keep the construction safe from moisture and water which can cause weakening of the structure and rotting. It helps to create a barrier between the moisture which protects the building from water and moisture damage.

Membrane damp proofing – It is made with PVC and it helps to stop the entering of water from building surfaces by sealing the area and covering with protective layers.

Surface treatment – Surface treatment involves applying chemicals to the building and make them water proof. It requires preparations of surface, application with proper technique and curing of the chemical for barrier.

Q1: Identify the application of the following floor framing types. [Pre-Manufactured joists], [Conventional bearers and joists], [Drop-in (or in-line or deep) joist construction], [Sub-floor frame, including timber or steel], [Sub-floor support construction]

Answer :
  1. Pre-Manufactured joists

It is used for rapid construction and consistent quality, often in residential and commercial buildings. They are good for strength and stability purposes and are used where the joists are to be placed.

  1. Conventional bearers and joists

It is used in wood framing for residential structures and these joints are made of timber or steel and attached using nails and screws permanently.

  1. Drop-in (or in-line or deep) joist construction

It is used for reducing the thickness of the floor.  It is fixed using fasteners which have proper load transfer and strength.

  1. Sub-floor frame, including timber or steel

It is useful for taking different loads and weights.  These are made for both steel and timber and used in commercial and industrial projects.

  1. Sub-floor support construction

It is used to increase the strength and load bearing of the structure. They help to support beams and walls and make the structure stay straight and strong.

Q1: What are the BCA specifications for the flooring systems and materials to be used in bushfire risk areas?

Answer :

Low Risk - Follow all Standard Building Practices

Medium Risk - Use non combustible material and use fire resistant materials

High Risk - Flooring must be of non combustible materials which are high in fire resistance and flooring must have gaps properly sealed for no fire spreading

Extreme Risk - Use non combustible material which is highest in fire resistance and sealed properly to prevent flame spreading.
