Quality has been the main issue in construction projects. In handling it, the quality control techniques during construction process are required to thoroughly carry out in order to avoid any mistakes which lead to bigger problem such as poor quality of project outcomes. The implementation of quality control techniques during site inspection is able to discard all possible negative effects towards construction projects. There are three quality control techniques that have been used during site inspection known as Project Quality Plan (PQP), Inspection Test Plan (ITP) and Checklist. In order to implement these techniques, there are some matters that need to be identified and overcome. Therefore, this study has been carried out to identify the challenges in implementation of quality control techniques during site inspection. To achieve the objective, the survey questionnaire was distributed among G5, G6 and G7 contractors’ in Malaysia. A total of 82 useable questionnaires were received and analysed using factor analysis. The challenges were clumped and categorized into respective groups. The seven groups were renamed, namely: (1) attitude, (2) documents, (3) operations, (4) management, (5) workers, (6) information and (7) methods. This study helps to improve the quality control techniques especially during site inspection among Malaysian contractors.
