Development framework of qlassic to improve defects identification in residential project

Defects in residential projects have been highlighted by buyers and quality control departments for many years. Defects in construction project are occurred due to many reasons. 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. Those are evaluation on soil work, extension on inspection, document submission on design and redo rectification. Therefore, based on the results, all parties including CIDB, residential developer and contractors should take this issue seriously and make efforts in the issue as it is considered important strategy to reduce defects in residential projects

Effectiveness of Quality Assessment in Construction Project

Malaysia is one of the countries which is growing rapidly and show a great result in construction. In real terms, the Malaysian construction industry registered positive growth, supported by large-scale investments under the government’s 10th Malaysia Plan. The growth of construction industry increases the perception of client on Malaysia projects. In current scenario, client have a high level of awareness on quality of outcome. The higher the quality achieved in building projects ensure the marketability and enhance of clients. As such construction projects that are able to be completed with distinctive quality will definitely enable to delight their customers. Thus, this study aims to identify the lacking in quality assessment as a strategy to improve quality of residential project. Therefore, objective of this study is to investigate the implementation of construction quality assessment in reducing number of defects in construction projects. Apart from that, this study conducted to investigate the limitation of construction quality assessment in reducing number of defects in residential projects. This study also conducted to develop a framework of construction quality assessment towards reducing number of defects in residential projects. The conceptual framework consists of major component that show lack of quality assessment and improvements in quality assessment. The finding shows that, there are lacking in quality assessment which affect the quality of construction project. Thus, this framework will be an effective strategy to improve the performance level of construction quality assessment

Synthesis of Construction Quality Assessment Model in Construction Industry

The achievement of quality is an important component in every handover of a residential project. Good quality plays an important role in creating a good identity for the developer as well as fulfill customer’s satisfaction level. Thus, Malaysian developers have started to implement quality assessment in their residential projects. Quality assessment is carried out to evaluate quality of project. However, even though quality assessment is implemented in most of construction projects, it is still a struggle to reach customer’s satisfaction level due to the number of defects in their residential properties. Therefore, this research carries the objective of investigate lacking of construction quality assessment and developing a framework on quality assessment to reduce defects in residential projects. This paper review requirements on construction quality assessment models which has been proposed by different researchers. The result of this study used to develop a framework on construction quality assessment to fulfil the important indicators which should be included in a quality assessment. The significance of this study may help contractors to develop projects with less defects and quality residential project
