Both civil engineers and architects are involved in planning and designing structures. However, a civil engineer will concentrate on making sure the structure will be safe and be able to endure everyday and extreme conditions, while the architect will focus on the aesthetics of the structural work, as well as concentrate on the look, feel, and functionality.
The civil engineer will analyze and evaluate the structural integrity of the design that the architect has created, and find ways to make the construction design possible by suggesting alterations/modifications in order to turn the architect's vision into reality.
Civil engineers and architects often work with each other, as their work sometimes overlaps. A good working relationship between the two professions will make a construction job more effective and successful.
