The final CE CONQUAS score for a project is based on the scores achieved in all assessments throughout the entire construction process.
Since its introduction in 1989, CONQUAS has been used as the basis to assess the quality of building projects.
A contractor is eligible for a preferential margin if the average CONQUAS score of their three most recently completed projects is over 65.
Obviously, the average CONQUAS scores have risen steadily and the number of contractors on the premium list has also increased.
Those contractors with high CONQUAS scores and ISO 9000 certificates will enjoy a tendering advantage for public sector projects under the premium scheme which is an important incentive for them to continue to hold up the quality standard that has been achieved.
The CIDB, through its quality and productivity promotion programme, has already developed a high-quality construction industry in the last decade and it intends to raise Singapore's construction quality standards to those of developed countries and envisages that by 2004 the average CONQUAS score of 78 points would be attained by quality-conscious contractors.
In order to measure contractors' performance against the defined standards and to compare between individual contractors, the performance assessment scoring system (PASS), which was developed based on Singapore CIDB's quality assessment scheme, CONQUAS, was adopted in February 1990.
Similar to Singapore's CONQUAS, monthly assessment for domestic blocks is as shown in Table IV.
The simple assessment systems of CONQUAS, BQAS and CE CONQUAS can measure the level of quality achieved by the contractors.
Modified from the CONQUAS, the PASS system used in HKHA has given an intensive monthly assessment to the building works.
