Quality Issues and Quality Control Approaches in the Installation Process of Structural Components in Building Construction Using the Pre-Engineered Building System (PEB)

Abstract

The Pre-Engineered Building System (PEB) has gained widespread popularity in the construction industry due to its ability to reduce construction time, minimize waste, and enhance structural efficiency, aligning with the development of sustainable and environmentally friendly infrastructure. However, quality control during the PEB installation process remains a critical issue that requires systematic management.

This study aims to investigate the factors affecting the quality of PEB structural installations and to identify practical quality control approaches. A qualitative research methodology was employed, including in-depth interviews with experts, field observations, and document analysis. The findings indicate that major factors influencing installation quality include pre-installation management, transportation, storage, labor management, and on-site quality inspection.

The analysis revealed that, in terms of personnel, a significant issue was the insufficient understanding of construction drawings and installation procedures, leading to incorrect assembly positions. Regarding installation processes, failure to follow the prescribed sequence resulted in structural misalignments and frequent rework, significantly impacting project timelines and costs.

Moreover, the study proposes the application of modern technologies, such as Building Information Modeling (BIM), Internet of Things (IoT), and 3D laser scanning, to enhance precision and efficiency in quality control.

The results contribute to the development of sustainable quality control standards for PEB installation, covering technical practices, procedural management, and workforce competency development, thereby promoting structural safety, stability, and minimizing environmental impacts in the long term.
