| Abstract | This study investigates quality management practices in interior Design–Build (D/B) projects, focusing on the VNG Campus interior package as a case study. While the D/B model has become increasingly common in Vietnam, its application to interior projects still faces challenges in quality control and coordination. The research aims to identify current practices, evaluate strengths and weaknesses, and develop an integrated framework to enhance quality management for interior D/B projects. The literature review established a theoretical foundation based on ISO 9001:2015, Total Quality Management (TQM), Lean Construction, DMAIC (Six Sigma), Quality Function Deployment (QFD), and SERVQUAL, integrated through the Plan–Do–Check–Act (PDCA) cycle emphasizing continuous improvement and client satisfaction. The case study examined the VNG Campus interior package across five key phases: design, procurement, production, construction, and handover. Data were collected from project records, direct observation, and participation within the contractor’s QA/QC system. Results show that the D/B model enables better integration, flexibility, and responsiveness, but weaknesses remain in detailed inspection planning, subcontractor performance, and QA/QC synchronization between factory and site. To address these issues, an Integrated Quality Management Framework (IQMF) was developed, linking all project phases within a PDCA-based system. The framework incorporates Lean tools, digital document control, and continuous feedback to improve coordination, reduce rework, and ensure quality consistency. This study concludes that effective quality management in interior D/B projects requires an integrated, process-based approach supported by digitalization, staff training, and continuous improvement. The proposed IQMF provides practical guidance for contractors and serves as a foundation for further research in data-driven quality management under the Design–Build model. |
