How do developer band ratings correlate with defect rates?

Question

Accepted Answer

Developer Band Ratings Show a Strong Correlation with Defect Rates

Developer band ratings exhibit a clear correlation with the incidence of major defects reported after the Temporary Occupation Permit (TOP). Specifically, developers classified under higher bands, indicative of superior quality and fewer issues, recorded significantly lower rates of post-TOP defects compared to those in lower bands. For instance, developers in band 1 reported fewer than one major defect per 1,000 units, while those in band 6 reported approximately 80 major defects per 1,000 units.
Higher Band Developers Report Substantially Fewer Defects

The data reveals a stark contrast in defect occurrences based on developer banding. Band 1 developers, representing the highest standard, demonstrated an exceptionally low rate of major defects appearing after a project received its TOP. This contrasts sharply with band 6 developers, who registered a defect rate that was approximately 80 times higher on a per-unit basis.
Lower Band Developers Associated with Boutique Projects and Higher Defects

A significant portion of projects receiving low band ratings under the Construction Quality Assessment System (Conquas), specifically bands 4 to 6, were smaller, boutique private residential developments. Over the past six years, 167 projects were assessed, with 48 falling into these lower tiers. Of these, 28 were identified as boutique developments, suggesting a trend where smaller project scales might be linked to poorer construction workmanship.
Conquas System Evaluates Workmanship and Defects

The Conquas system is designed to assess the quality of workmanship and identify major defects, such as water seepage, cracked tiles, and broken fittings. Both project-level assessments and developer banding contribute to the overall quality assessment. The Building and Construction Authority (BCA) uses these evaluations, including feedback from homeowners post-TOP, to assign band ratings, thereby informing potential buyers about the expected quality of construction.
