Quality management in precast construction: a stage-wise assessment and technological perspective

Precast construction has become a preferred method in modern infrastructure due to its advantages in quality control, speed, and sustainability. However, maintaining consistent quality across production, transportation, erection, and post-construction stages remains a challenge. This study presents a stage-wise evaluation of quality aspects in precast construction, supported by a case study of the Gudivada Flyover project. The literature review traces the evolution of quality management from manual inspection to digital technologies such as BIM, IoT, and digital twins. Findings confirm that factory-controlled production ensures uniformity, but transitional phases are vulnerable to defects. Integration of advanced monitoring tools significantly improves durability, safety, and lifecycle efficiency.
