The Maquan Middle School project covers a total construction area of approximately 67,100 square meters. The main construction components include a junior high school teaching building, an elementary school teaching building, a comprehensive building, student dormitories, a cafeteria for students and faculty, an indoor sports ground, underground structures, outdoor works, and landscaping. The project involves numerous construction processes, a wide range of techniques, and high technical requirements.
How to effectively manage technical quality and consistently deliver high-quality, branded projects has been a constant consideration for the project's technical team. Since the project's commencement, Deputy Chief Engineer Gao Pan, along with the technical team, has actively engaged in benchmarking exchanges, consulted reference materials, and summarized experiences. Through continuous experimentation and improvement, the project successfully established and implemented a QR code inspection system and sample zone.
On the construction site, quality inspection QR codes are ubiquitous, serving as powerful tools for quality controllers. During inspections, if an issue is identified, the quality controller simply needs to take a photo, scan the QR code, upload the photo and description of the problem, and forward it to the team leader. This process prompts the team to make timely corrections according to specifications.
"The use of QR codes has made quality inspections more effective and, to some extent, reduced our workload," said technician Liu Wenbin. With numerous work sites, it's easy to lose track of issue follow-ups and corrections during busy periods. Since implementing QR codes, a simple daily scan allows real-time tracking of rectification status via the system backend. This straightforward approach has significantly boosted work efficiency.
In addition to quality inspections, the project also utilizes QR codes for safety briefings, technical handovers, and the three-inspection system. Leveraging informatization means, the project's quality control standards have markedly improved.
Another "secret weapon" for quality management is the visualized handover sample zone. The project's sample handover area is divided into three modules: a main frame-shear structure sample, a strip foundation sample, and a sample display area. Standardized and regulated samples clearly demonstrate the expected outcome after each minor construction step, providing workers with a tangible reference. Before construction begins, technicians bring workers to the sample zone for technical handovers, explaining key points with the physical samples, which helps workers quickly grasp the technical essentials.
"Now, by looking at the samples while listening to the explanations, we know exactly what to do," workers commented. They noted that the sample zone is immensely helpful, enabling faster work with higher quality, significantly reducing rework, and improving overall work efficiency.
To meet the demands of different construction phases, the project plans to further expand the sample zone. Based on the onsite construction progress, four additional sample modules will be developed: stair treads, wall masonry and plastering, roofing works, and water supply, drainage, and electrical systems. These will provide technical assurance for onsite construction. In the future, this extensively developed sample handover zone will become a standout feature of the site's safe and civilized standardized construction practices.
