    My builder is asking for a wind rating assessment to be done before we go to site.

    I have checked on the Structerre website, and it describes this assessment as:

    "Wind conditions impact the design of your building. Our classifications provide the essential information you need to ensure your design is tailored to suit the environmental conditions."
    Structerre Consulting Engineers | Perth Brisbane Sydney Melbourne Bunbury Geraldton Albany | Services | Geotechnical

    But my development is already designed and is about to have final working drawings signed off.

    Anyone know what these wind rating assessment reports are actually for?

    Thanks!

    Some sites may need sections of a development to be strengthened so this would include but is not limited to pining all roof tiles, higher levels of glass strengths, more bracing in the walls etc.

    @Chilliblue has described what is needed, and when this is needed will be if you are within a new area and not many other houses around you to provide protection, a double story or coastal areas. This should have been covered in your soil test and site survey if you have had one completed.

    Where does the wind rating requirement comes from?

    Is this specific to a block?

    is this given in the council DCP ?

    The wind rating in usually classified by the area, not specific to a specific site. A quick call to your drafty and/or engineer should confirm.
    There is an Australian standard somewhere with pretty pictures, it's similar to needing extra corrosion protection for concrete if within x km of the ocean.

    Found it!

    Wind Loads for Housing

    Your engineer and design should have covered it.
    Before "engineering" the house, they'll categorise the area and factors which will determine the structure type, fixings, material selection etc etc etc

    And remember that often it does not include the entire structure just sections.
