Compliance path 5: Comparison with a previously accepted Alternative Solution

This can be a fairly straightforward way to provide evidence of Code compliance.

This option uses an Alternative Solution that a building consent authority has previously accepted. 

The documentation must demonstrate that the solution is working in practice, as prior acceptance does not guarantee its performance.

The solution must also be directly comparable and relevant to the proposed situation. 

The BCA is not obliged to accept an Alternative Solution that it has approved previously, and nor is it obliged to accept an Alternative Solution approved by another BCA.

When to use this option

This option may provide a simple path to acceptance as a result of the solution having been accepted by another BCA.
