Technical help with Australian building codes

Builders, trade contractors and building designers all need to understand the requirements of the Building Code of Australia (BCA) to ensure that the homes you design and build comply with the law.

The BCA refers to over a hundred Australian Standards. It’s not impossible, but it is difficult and expensive for you to buy and maintain up to date copies of all of these documents.
