CONCLUSION OF TRAINING

• THIS TRAINING IS COMPREHENSIVE IN FILLING THE GAP BETWEEN THE THEORETICAL & PRACTICAL STUDIES

• AT THE SITE THERE WAS A GOOD MANAGEMENT SYSTEM BETWEEN THE CONTRACTOR, THE CONSULTANT, AND THE CLIENT.

• I FOUND THAT THERE WAS GOOD UNDERSTANDING BETWEEN THE SUPERVISOR AND THE WORKERS, THOUGH WORKS ARE INTERDEPENDENT BUT THERE WERE NO CONTRADICTION BETWEEN THEM.

THANK YOU
