| Summary: | Construction defects are always of great concern in the industry because they cause delays before handover and raise maintenance costs when buildings are occupied. Despite numerous studies on the nature of defects occurring, it has been difficult to systematically review this research problem due to the absence of review techniques, making it difficult for researchers to replicate or interpret the results. Therefore, this study performs a systematic literature review (SLR) on the nature of defects occurrences of construction defects in construction projects. The review process included four key methodological steps, namely systematic searching strategies based on identification, screening, and eligibility on several established databases such as Scopus, ScienceDirect, Google Scholar, Emerald Insight, and Web of Science, followed by data extraction and analysis. Four main themes were discovered based on the types of construction defects: (1) architectural defects, (2) structural defects, (3) mechanical defects, and (4) electrical defects. These four themes were divided into twenty-two sub-themes. Lastly, four themes were discovered based on the causes of construction defects: (1) design defects, (2) material defects, (3) workmanship defects, and (4) maintenance defects. © 2024, Construction Research Institute of Malaysia.
