<![CDATA[General Background Leading precast concrete manufacturers place great emphasis on product quality to maintain brand reputation and satisfy high construction standards. Specific Background At PT XYZ, pile foundation production requires a comprehensive quality control system spanning from material selection and reinforcement assembly to final product inspection. Knowledge Gap However, detailed empirical evaluations examining how rigorous inspection procedures across spinning, curing, and molding stages minimize structural defects remain essential for operational excellence. Aims This study aims to examine the quality control process in the production of pile foundations at PT XYZ. Results The findings indicate that consistent quality control application across material preparation, wire caging, spinning, and curing ensures technical specification conformity, minimizes production defects, and preserves structural durability. Novelty This work provides a systematic descriptive evaluation of end-to-end precast spun pile manufacturing workflows combined with monthly defect rate monitoring. Implications The results offer practical frameworks for precast concrete industries to maintain product quality, process efficiency, and long-term customer satisfaction. Key Findings Highlights Quality control is applied systematically across every production stage from material preparation and wire caging to final inspection. Rigorous inspection procedures ensure product conformity with technical specifications while maintaining the strength and durability of spun piles. Monthly defect analysis demonstrates low defect rates below one percent, proving the effectiveness of consistent quality supervision. Keywords Quality Control, Precast Concrete, Spun Piles]]>
