A project delivery mechanism often used by government entities for public infrastructure projects involves entering into an agreement with a private sector party, which assumes all duties related to the project, including design, construction, financing, operation, and maintenance. In return, the private party receives fees from end users or payments from the government for a specified period, after which control is transferred back to the government. This structure is preferred because it shifts most project risks to the private sector and allows the government to undertake projects beyond its financial or technical capacity.
