DtS vs performance: which to use and when?

The National Construction Code (NCC) is a performance-based document that permits deemed to satisfy solutions (DtS), performance solutions, or a combination of both, to satisfy the NCC Performance Requirements.

The introduction of a performance solution pathway was intended to provide flexibility for designers and deliver alternatives to the DtS.

However, the Centre for International Economics (2012) found that only 50% of the NCC’s potential benefits ($1.1 bn) are being realised, prompting the ABCB to launch an initiative to encourage the increased use of performance solutions.

Central to this is the need to increase the level of assessment, given that performance solutions, unlike DtS, may not carry a government-endorsed level of safety.

Without such backing, performance solutions are less appealing, a problem that has been exacerbated by fallout from the current cladding crisis.

This presentation explores the limitations of a deemed to satisfy pathway, when a performance solution is appropriate, and how it should be developed.
