Prefabricated Underground Stations (PUS) face challenges in safety monitoring and assessment during assembly construction. First, the PUS-based DOFS system was established. Second, a progressive multiscale performance evaluation framework for ‘section-component-structure’ constructed. Finally, PUS Construction Intelligent Monitoring Assessment Model (PUS-CIMAM) developed by integrating above two modules. The results based on case study indicate that: (1) is suitable components of various shapes, offering high accuracy spatial resolution. (2) accurately captures component deformation stress evolution construction, demonstrating adaptability, accuracy, intelligence. (3) PUS-CIMAM indicated that process components, particularly large-span roofs, significant control point. (4) showed how adjacent ring construction affected structural current ring, which could be restored after second ring.
