Engineering quality refers to a project’s ability to meet specified requirements and user needs. This goes beyond simply adhering to the technical standards outlined in contracts; it also involves fulfilling the practical needs of end-users. Quality is primarily assessed based on the final deliverables. As a key evaluation metric of practical value, quality plays a central role throughout the entire construction process.
According to the systematic approach to quality control in construction projects, BIM (Building Information Modeling) technology can optimize quality management across three main stages: pre-construction, during construction, and post-construction.
1. Pre-Construction Control
This stage involves all preparatory activities carried out before construction begins to ensure quality management. The focus of quality control here is prevention rather than problem detection. For prefabricated buildings, BIM models enable component pre-assembly, which helps identify hidden design issues early and allows for reasonable modifications based on these findings. In super high-rise buildings, BIM-based collision detection for fire and rainwater pipeline installations improves both construction efficiency and quality.
2. Control During Construction
This phase supervises and regulates quality-related activities throughout the actual construction process. It consists of two stages: self-control and monitoring. During self-control, operators use the BIM 3D model to compare the construction site with the ideal design, enabling them to detect and correct errors promptly. Monitoring involves management personnel analyzing feedback from various construction sites via the BIM online system, simulating the impact of ongoing construction on the model, and proposing effective solutions.
3. Post-Construction Control
After construction is complete, BIM models are used to inspect and verify the quality of the final work. This stage addresses any deviations or issues identified. While pre-construction and during-construction controls are critical, unforeseen circumstances may still arise due to systematic or random factors. Although post-construction corrections may increase costs, timely and comprehensive solutions can minimize losses. BIM facilitates this by simulating and validating corrective measures, quantitatively assessing their costs, structural impacts, and other factors, thereby ensuring quality remains under control.
