Hi manthan, 

Basically civil engineers who work along with architect are those who are specialized  for structural  engineering. Architecture is a licensed profession but other are not.

Both civil engineers  and architect involved in planning and designing structures. Some it's work get collide. And the relation between these two professionals to make a construction job more effective. And  getting conclude on that node that YES architecture become a civil engineers.

Hope this answer help you. 

Thankx
