Building and Energy’s Audit Branch carry out technical inspections of ongoing building work to check how building standards are being applied. To date the majority of inspections have been on class 1a buildings (houses). In addition to the current audit activities Building Energy will focus audits and inspections on the following building work:

  • wet area waterproofing in all classifications; and
  • class 2 (residential buildings containing two or more dwellings)

Building and Energy gathers statistics from the technical inspection activities undertaken. From this data we can identify areas of building work that require improvement. The following list shows the top 6 areas that require improvement with a brief summary of why they were unsatisfactory:

  1. Wet areas waterproofing and external weatherproofing
    Omission of puddle flanges, bond breaker at floor/wall junctions, build thickness of waterproofing membrane, waterstops and flashings, weatherproofing at zero lot walls.
  1. Termite management
    Required reticulated systems omitted, placement and installation of physical barriers not in accordance with manufacturers’ specifications.
  1. Timber wall framing
    Required bracing omitted or not installed in accordance with 1684.2, connections to all parts of frame, structural member placement not in accordance with engineers design.
  1. Bushfire requirements
