General


  • What is the difference between Quality Mark and CONQUAS?

      Under the BCA Quality Mark for Good Workmanship (QM) Scheme, BCA will assess all the internal finishes and waterproofing works in each unit. The unit will be issued the QM certificate if it meets the specified standard.  If the unit does not meet the standard at first assessment, the developer may rectify the unit and apply for re-assessment.  There is no limit to the number of re-assessments. The QM certificate will be issued only after the minimum QM score is achieved.

      Under CONQUAS, only samples are taken of the Structural, Architectural and Mechanical & Electrical (M & E) works throughout the duration of the project.  The CONQUAS score is determined based only on the initial assessments. It is based on a “first time right” principle.  There is no provision for re-assessment.


  • Is there any portal that allows me to search and compare CONQUAS scores and Quality Mark ratings by properties, developers or contractors?

      The information on this webpage provides a platform for homebuyers to make a more informed decision when buying a home. Search and compare CONQUAS/Quality Mark performances of housing developments, developers and contractors in Singapore which reflects their workmanship quality standard.

      The Construction Quality Assessment System (CONQUAS) was designed to standardise quality assessment of workmanship in structural works, architectural works and mechanical and electrical works, by sampling.

      The BCA Quality Mark scheme assesses internal finishes in every newly completed housing unit of the project. In view of the more thorough assessment of finishes, homeowners experienced a much lower rate of defects in Quality Mark-assessed projects, according to an independent survey conducted by J.D. Power* in 2015.

      *A survey on workmanship quality of Quality Mark vs non-Quality Mark residential properties was conducted by global market research consultant, J.D. Power in 2015.


  • Does Quality Mark cover design and materials specification?

      QM is primarily based on quality of workmanship achieved. It does not cover design and materials specification. For example, it does not assess any design inadequacies like fitness for purpose, poor ventilation, insufficient corridor width, etc. It does not check whether the materials used are in accordance to the specification. Homeowners will need to check that the materials used are in accordance to those specified in the Sale & Purchase Agreement.


  • What are the benefits of Quality Mark?

      The homeowner can generally expect better quality homes if the project is QM certified compared to non-certified homes. A QM home provides the assurance that the unit has been thoroughly assessed and meets the minimum standards of good workmanship and toilets/bathrooms water ponding requirements as specified under the scheme.

      Each unit that meets the specified minimum workmanship quality standard and water ponding test requirements will be issued a Quality Mark (QM) certificate (as shown below). No certificate will be issued for any unit that fails to do so. The QM certificate certifies the condition of the unit at the time of inspection. The assessment does not cover quality of material, design or aesthetic preferences.

      benefits of Quality Mark

      QM only assesses the workmanship of units at completion. Any patent defects will be visible and will affect the QM score. It does not cover latent defects that may appear after handover or during the defects liability period. Such defects cannot be foreseen during assessment.


  • Can I engage BCA to establish a defects list for my property based on Quality Mark assessment?

      The Quality Mark assessment is devised to provide a score for an individual unit based on CONQUAS standards.  If there is an issue on quality or defects in the property, this should be taken up directly with the developer in accordance with the terms in the Sale & Purchase Agreement.  If need be, homeowners may want to engage building surveyors or other professionals for advice.


  • Does BCA provide Quality Mark assessment for overseas projects?

      Presently, QM assessment is available only to projects within Singapore. However, BCA does provide a limited form of architectural internal finish assessment based on CONQUAS for overseas projects. Some foreign developers/contractors find this useful for benchmarking purpose or to add value when marketing their projects.


  • Which projects are eligible?

      The QM scheme is open to all new private residential projects e.g. condominium, apartments, cluster housing, landed housing, residential units in mixed developments, etc. Participation in the scheme is voluntary.


  • Assessment Process


  • Scope of assessment

      The QM scheme measures the quality of workmanship in each newly completed residential unit. The assessment covers all internal finishes like floor, wall and ceiling finishes, architectural components and fittings like doors, windows, wardrobes, kitchen cabinets, vanity tops, bathtubs, water closets, shower screens and basins, and M & E fittings and switches. In addition, the assessment includes water ponding test for bathrooms. Water - tightness tests on windows are optional.


  • Who are the assessors?

      The assessors are trained specialists from Building and Construction Authority. They act as independent third parties engaged by the developer to carry out the assessment work.


  • Assessment criteria

      The assessment is based on a combination of visual assessment and measurement by tools to verify compliance to tolerances and standards set out in the CONQUAS® manual.


  • Standard and Defects


  • What does a Quality Mark score of 80 represent?

      It means that when the items in the unit were checked for workmanship quality, 80% met the standards as set out in CONQUAS.


  • What happens if my unit score is below the required score for QM?

      If the unit does not meet the minimum score, the developer can make good the defects and request for a re-assessment. Similarly, if the toilets/bathrooms within the unit fail the water ponding test, the developer can address the leakage and request for a re-assessment. There is no limit to the number of rescore attempts. No QM certificate will be issued until the unit achieves the minimum score and meets the requirements of the water ponding test.


  • How do I know whether an item is defective?

      For more information on defects, you may visit the quality standard page on this web site to find out various types of unacceptable defects.


  • If I am unsure about the workmanship standard, where can I find out?

      You may visit the quality standard page on this web which has a number of photographs featuring acceptable workmanship standards. It is based on acceptable standards and best practices as determined by appropriate members of the industry.


  • Is a unit with Quality Mark defect free?

      As a unit need to score only at least 80 points (out of 100) to qualify for a QM certificate, this means there may still be some defects, albeit minor, in the unit. However they are not significant enough to warrant withholding issue of the QM certificate. Major defects, e.g. leakages in the toilets/bathrooms and functionally deficient doors/windows, if any, would have been addressed before a unit is issued the QM certificate.


  • Does Quality Mark cover future defects?

      QM only assesses workmanship of units at completion. Any patent defects will be visible and will affect the QM score. It does not cover latent defects that may appear after handover or during the defects liability period. Such defects cannot be foreseen during assessment.


  • Do I need to maintain my QM unit?

      Aging and wear and tear of materials is a normal process. To preserve and maintain the quality of the QM unit, homeowners need to perform regular checks, cleaning and servicing in accordance with the manufacturers' recommendations for maintenance. The following are some tips for proper maintenance of common materials and components:

      Agglomerated marble

      • Remove spillage immediately.

      • Avoid using cleaning agents containing soluble slats like sulphate or chloride.

      • Use neutral cleaner or plain water for regular cleaning maintenance.

      Timber Flooring

      • Ensure all external windows and doors are shut to prevent rain water from splashing     onto the timber flooring.

      • Where possible, keep internal doors and top hung windows at bathrooms open to allow     better natural ventilation of units which may be left vacant for a long period of time.

      • Liquid spills can be absorbed and stain wood permanently. Hence they should be     cleaned immediately.

      • Avoid walking on timber flooring with cleats, safety boots and other footwear that may     damage the flooring.

      • When moving heavy furniture or equipment, do not slide it on timber flooring. It is a     good practice to lift and carry the furniture or equipment to protect the timber flooring.

      • Avoid leaving stagnant water on the timber floor.

      Windows

      • Clean and remove dirt from movable parts such as the sliding shoes, pivot points and     track as often as necessary.

      • Lubricate or grease the movable parts, hinges, screws and pivot points at least once     every six months.

      • Check the glass panes for cracks and ensure that the panes are not loose.

      • Tighten loose rivets/screws or replace missing or corroded rivets/screws.

      • Replace damaged friction stays and adjust screw on sliding shoe if necessary.

  • Fees and Charges


  • Do I need to pay for the QM service?

      As a homeowner, you do not need to pay for this service. This service is paid for by the developer or builder when they apply for the development to be assessed under the QM scheme.


  • Information on QM Projects


  • How do I know my home or a property I intend to purchase is a Quality Mark project?

      BCA compiles and publishes a list of projects that have been assessed or committed for QM assessment at https://www.bca.gov.sg/QM/projects.aspx. You can use the search facility to check the list of QM projects, their developers and contractors. Some project details are also available. Alternatively, you can check with the developer on whether the project has or will be committed to the QM Scheme before booking a unit in the development.

      A mobile application is also available where homeowners can access similar information using their smart phones.


  • If my development was assessed under Quality Mark scheme, how do I know the Quality Mark score for my unit?

      All units that have passed the minimum standard (80 points out of 100) and other requirements as specified will each be issued a QM certificate. The score will not be shown on the certificate. Under the scheme, BCA will provide to the developer/builder the detailed results of each unit that include an overall score for the unit. Depending on your purchase agreement with the developer, you may be able to obtain the score or a copy of the QM certificate for your unit.


  • How do I know which developers or builders deliver high quality projects?

      Any project committed to the QM scheme can be expected to meet high quality standards. However, developers and builders which consistently deliver high quality projects are also recognised through BCA Quality Excellence Award; an annual award given out from May 2013. This information can be obtained from BCA's website at http://www.bca.gov.sg/Professionals/IQUAS/QEA.html
