Section 19A(1)(b) of the Building Act 2004 (ACT) requires that previously carried-out building work have been carried out in accordance with all of Part 3, not merely s 42. Where prior work was not carried out in accordance with Part 3, a certifier can only be appointed under s 19 for future work. The approval process under ss 28-29 requires the certifier to consider matters beyond the plans alone, including the nature and quality of existing work on the site, particularly under s 29(1)(f) which requires satisfaction that the building as proposed will be structurally sufficient, safe and stable.
