Quality in constructed projects is crucial for ensuring safety, longevity, and functionality. High-quality construction ensures that buildings, roads, infrastructure, and mega construction projects can withstand wear, weather, and use over time, minimizing the risk of costly repairs or failures. High quality also enhances the comfort, safety, and health of occupants, reducing the potential for accidents, rework, or other structural, mechanical, and electrical issues. Moreover, quality workmanship reflects professionalism and helps to meet legal and regulatory standards, avoiding legal and financial consequences, some of which can be severe. Quality construction also promotes sustainability and brings higher profits for the contractor while satisfying project owners, thereby assuring success. This book is designed to help construction professionals advance the cause of quality in the built environment, as well as serve as a textbook for students learning quality control in construction.
