Employing advanced structural analysis software, the research simulates various load scenarios to ensure compliance with national and international building codes. It evaluates cost-benefit tradeoffs between different design choices, materials, and construction methods, emphasizing sustainability and lifecycle performance. The thesis also considers fire safety engineering, accessibility standards, and the integration of flexible interior layouts that allow for future adaptation. By combining technical rigor with practical application, it provides a blueprint for multifunctional building design in densely populated urban areas.
