ABSTRACT
ABSTRACT: Governments, all over the world, are using the B.O.T. (Build, Operate and Transfer) solution to finance large infrastructure projects, when public budgets are not available. As, in this system, the technical aspects of design, construction, operation and maintenance (during the concession period) are developed by the concession company, after the signature of the concession contract, the quality of the final infrastructure needs to be very well defined during the initial tender phase. In fact, afterwards, all the missing aspects will definitely lead to the most economical solution.
