<p>The construction industry is one of the fastest growing and most profitable in the world. The industry is vital, especially in Qatar where infrastructure is growing.

Robust pre-qualification procedures for contractors, improved designer–contractor communication, incorporation of cutting-edge project management systems and efficient risk management techniques were among the useful suggestions that surfaced.
