Thus, construction quality assessment is implemented in residential projects to ensure the project is built to satisfying quality and safe for its occupants. Quality Assessment System in Construction (QLASSIC) is intended as measurement system on workmanship quality in a construction project. The evaluation will be based on Construction Industry Standard (CIS 7:2006) where the workmanship quality in a construction project is evaluated and the end product is called as scoring system. However, the quality of QLASSIC evaluation has started to be questioned by buyers due to the increasing defects in residential projects. Therefore, this study being carried out to explore on the issue. The study consisted of three main objectives; to identify type of defects occurring in QLASSIC implemented residential project, to investigate the limitations of QLASSIC on defects in residential projects and to develop framework of QLASSIC on defects in residential projects. This study conducted with Malaysia private residential developers whom won QLASSIC Achievement Awards from year of 2015 to 2019. 7 developers’ companies involved. This research orientated qualitative method and interview question being used as research instrument with 35 respondents. Data was analysed by using NVivo 12 Plus software. Based on the data analysis, a framework has been developed to improve defects identification in residential project. Indicators in framework has divided into four elements. Those are management, technology, material/ equipment and content. Under management there are two improvements. Those are increase quality of training for CIDB assessors and inspection on workmanship. Under technology element, usage of laser scanning, embedded sensor and ultrasonic inclusions are steps toward improvement. Evaluation on material consider as an improvement under material and equipment. Apart from that, improvement also has been proposed under content of QLASSIC.
