SR355 Consent documentation quality for new housing (2019)

This is the third and final report on a study of new housing construction quality. In this project, it was decided to investigate the quality of the building consent documentation. A total of 52 sets of drawings were inspected – about 50% on site and the rest in the office of the building inspectors. The two main categories of concern were readability and completeness.

The on-site inspections also checked whether the details on the drawings were followed in practice. The project found that quite a high percentage of drawings did not have adequate or complete details
