In China, the construction industry primarily emphasizes progress and cost efficiency, often overlooking the management of building quality. Even the final quality acceptance process lacks standardization, resulting in numerous safety hazards. Implementing information technology in quality management can effectively address issues caused by information silos and gaps, thereby enhancing the quality acceptance process.
The current quality acceptance process mainly relies on random inspections conducted by quality inspectors after components are completed. If the inspection results are unsatisfactory and the quality is deemed unqualified, this often leads to extensive rework on numerous components. However, if components can be tracked in advance and their quality status monitored in real time, it can significantly reduce costs and minimize the need for rework.
Additionally, if quality inspectors lack a thorough understanding of testing schedules, requirements, or procedures for components such as beams, slabs, and columns, the inspection results may not meet standards. Delayed responses or overlooked issues during testing can embed quality and safety risks early in the building’s lifecycle, ultimately compromising its overall durability and service life.
Applying BIM technology to quality acceptance enhances both the thoroughness and standardization of inspections. A key step is accurate positioning. Given the large scale of construction projects, it is challenging for inspectors to pinpoint the exact location of components in real time. By creating a BIM model, each component can be assigned a unique ID code, simplifying location tracking and retrieval.
During construction, workers can input component implementation data into a shared platform using the 3D model database, enabling real-time feedback and supervision. This allows quality inspectors to quickly locate components requiring inspection, access comprehensive information, and perform standardized checks in accordance with the Code for Acceptance of Construction Quality of Concrete Structures. Inspectors can then determine whether the quality meets standards, document their findings, and maintain strict control over quality acceptance levels.
