Generally Building Code Regulations (BCA or Building Code of Australia) are a uniform set of technical provisions which assist designers and specifiers design and construct buildings and other structures in the local building environment. 

The aim of the Building Code of Australia or any other International Building Code for that matter is to ensure consistency and eliminate ambiguity by reducing overarching and prescriptive safety requirements. Ultimately any applied Building Code Regulations is sanctioned by a rigorously tested rationale; delivering a high degree of safety and remaining cost-effective and efficient, circumventing being prescriptive or restrictive to the designer and /or specifier. 

Deem to Satisfy Provisions relate to systems or building solutions which satisfy specific levels of performance requirements. Normally such performance requirements relate to an alternative solution: a Deemed to Satisfy Provision… OR a combination of them. Alternative solutions or Deemed to Satisfy Provisions normally make use of Designs or Building Solutions where the system or product manufacturer or installer can rely on a Fire Safety Certificate or Certificate of Conformity having been previously issued. 

In most cases, buildings must use a type of fire resisting construction that is specified in Table C1.1 or SPECIFICATION C1.1. TYPE A CONSTRUCTION is the most fire resisting (resistant) construction followed by TYPE B CONSTRUCTION and with TYPE C CONSTRUCTION being the least fire resisting (resistant) construction.
