Do you think that the site works will assist a new graduate engineer to grow and increase his professional capabilities more than office works?

Sure

having a good experience in site is enriching the engineer experiences since he is living with the site problems and practising and coordinating it on site 

Yes.  An Engineer should get first-hand experience from site.  This will give him full exposure to the conditions, interaction with various entities like subcontractors, suppliers, consultants, clients representatives, etc.  Also, he will understand the requirements of the project like planning, material management, etc.

I feel as far as Construction industry is concerned having site experience at the start of your career definitely helps a lot. Working at site help you to understand the common as well as measure issue we face while practically implementing the design. This way it is definitely helpful to avoid measure or common design mistakes.

Exactly. Once after he got understood all construction sequence and techniques from site ; he can do his office job better and be a good engineer eventually. 

yes.because they can learn innovative thinking from day by day activities

oui.

seulement il doit passer par la phase de bureau pour maitriser les calculs.

graduation is like a birth , let him learn walking in site , see things practically and realistically happening , before any kind office based coordinator or designer

yes,i think that ,and i start my work on the site beside the designe in the office; finally the work on the site was more useful

Yes, I think so. A Graduate Civil Engineer to work at site first to increase the professional capabilities.
