The Three Pillars of Quality: The Role of Three-Phase System in Construction Quality Management  

In the dynamic world of construction projects, ensuring quality is a fundamental objective that directly impacts the project's success, site safety, and stakeholder satisfaction. Quality management plays a vital role in maintaining high standards throughout the project lifecycle, from design and construction to completion and beyond. As construction practices continue to evolve, new technologies and methodologies emerge to streamline processes and enhance project outcomes. One such powerful tool in the construction industry is the three-phase control system.  

Given the lack of detailed information in the literature on three-phase control systems, this paper aims to fill the gap by providing a detailed overview of the subject. It discusses the importance of the system and how it can improve quality management in construction projects. The system comprises three phases - preparatory, initial, and follow-up. Each phase of the system has its own set of activities, inspections, and tests. By using this system, construction professionals can identify and address quality issues early in the process, which can help to reduce rework and ensure that projects comply with the specified quality standards.

This can be defined in terms of specific features, such as durability or performance, or in terms of more general qualities, such as usability or aesthetics.&nb...
