"How does the theory of civil engineering principles and practices serve as the foundational framework for the design, construction, and maintenance of infrastructure projects? Discuss the significance of theoretical knowledge in areas such as structural analysis, materials science, fluid mechanics, and geotechnical engineering in ensuring the safety, durability, and sustainability of civil structures. Explore how theoretical concepts inform decision$-$making processes in project planning, risk assessment, and environmental impact analysis. Furthermore, examine the role of ongoing research and innovation in refining theoretical models and advancing the field of civil engineering to meet evolving societal needs and challenges."
