Architects are responsible for designing construction projects like homes, bridges, and public buildings based on client needs and specifications. They must understand client requirements, develop designs and plans that meet codes and client preferences, and oversee construction to ensure the project aligns with the original design. Key responsibilities include creating initial sketches, considering infrastructure needs, getting necessary approvals, managing budgets and schedules, and inspecting ongoing work. Effective architects balance client visions with practical and regulatory factors through creative solutions.
