The BCA Quality Mark (QM) for Good Workmanship was launched on 1 July 2002 to encourage developers to consistently deliver quality homes, in-line with the rising expectations of Singaporeans for better workmanship.
Under the scheme, BCA will assess every unit of newly completed private residential projects. The QM certificate will be issued to individual apartment unit that achieve a score of at least 80 out of 100 points (a minimum CONQUAS score for internal finishes), without any major defects and water seepage in the toilets/bathrooms, and windows. The QM certifies the condition of the apartment unit at the time of inspection.
Who can apply
This voluntary scheme is open to developers and builders who:
- Have earlier projects that achieved the minimum CONQUAS score stipulated by BCA; and
- Have submitted the same project for CONQUAS scoring.
The project team (developer, builder, subcontractors, supervisors, etc) is advised to attend the CONQUAS training to ensure the team is adequately equipped with knowledge of the CONQUAS standards and scoring system. This is a 1-day course conducted at the BCA Academy.
BCA has revised the following QM standards to further raise the quality of private residential homes:
- Raise QM threshold score to 85 points from current 80 points; and
- Revise QM tiered rating criteria as shown in the table below.
|QM Tiered Rating
||Average QM Unit Score*
||Waterponding Test Passing Rate**
||Window Water-Tightness Test Passing Rate***
(Based on CONQUAS sampling)
||92 Points and above
||90 to < 92 Points
|99% and above
||99% and above
||85 to < 90 Points
