Correction: Structural fire endurance (S) ratings for single-storey buildings

A Codewords article in December 2007 addressed whether S ratings should be applied to large, unsprinklered single-storey buildings. The article included an interpretation that S ratings be required in single-storey buildings remote from boundaries.

However, the original intention was that single-storey buildings remote from boundaries could still be unrestricted in floor area, and not require elements of construction that are designed with an S rating.

The current Compliance Document does in fact permit non-rated construction in single-storey buildings remote from the boundaries, and the floor area of such buildings may also be unrestricted.
