University Assignment: CPCCBC4001A - Project 1 BCA Compliance Check

This assignment assesses the student's understanding of the Building Code of Australia (BCA) and its application to low-rise building projects. The assignment is divided into three projects. Project 1 requires a BCA compliance check for a Class 1a dwelling, including fire safety, health and amenity, and safe movement. The student must present the compliance check in a clear table format, referencing relevant BCA sections, performance requirements, and Australian Standards. Project 2 involves classifying a multi-story building (Class 2) and identifying the BCA sections and clauses related to fire resistance, access, and egress, and other essential services. Project 3 requires classifying a factory and office building and assessing its compliance with access, egress, and fire safety requirements, also using a table format to present the findings.

CPCCBC4001A Apply building codes and standards to the construction process for low rise
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.

Assuming that only half of each window is open able.
However, as the unsuited and powder room windows
are awning windows, only a small proportion of the
window will open. Therefore, these are unlikely to
comply with the 5% rule. Mechanical ventilation with
external ducting is necessary.
