building: Assessment 3
What you have to do
Make any assumptions you need to, but be sure to include them as part of your assessment.
Question 1 – Project 1
This question relates to Project 1. You will need the Project 1 documentation and access to
the relevant volume of the Building Code of Australia.
You are required to undertake a BCA compliance check for the dwelling in Project 1.
Present it in a format which is easy to follow and understand.
When you are checking compliance against a document such as a Standard or the Building
Code of Australia, it is useful to present your information in a table. This makes it easy for
you, or anyone who picks up your document, to follow your assessment. An example of the
headings you may want to use is shown below.
