ABSTRACT = {Quality attainment in public construction projects is paramount for effective project management. This study employs Principal Component Analysis (PCA) in the initial phase to discern noncollinear critical defects from inspections across 1015 projects. The identified components are categorized into three aspects: Inspection Records and Occupational Safety and Health (Aspect I), Concrete Quality (Aspect II), and Construction Team Quality Management (Aspect III). Subsequently, a Multilayer Perceptron (MLP) network, trained on 13 PCA-identified critical defects, transforms input data into a probability, indicating project quality. The MLP model exhibits exceptional performance with 91.3% accuracy, 90.2% precision, and 96.1% recall. This hybrid machine learning approach effectively extracts and correlates defect-related information with construction quality, providing a robust tool for accurate quality prediction in construction projects.},
