Infrastructure facilities are often designed, constructed, and operated by a team of firms, each bringing their respective skills (i.e., design engineering, turnkey contracting, equipment supply, and facility operation) and expertise to the project's undertaking. Privately financed projects focus accountability on team members for the scope under their control. For example, these projects are typically based on a fixed-price, turnkey contract for the design and construction of the facility. The turnkey contractor is often a partner in the joint venture. This approach shifts the risk of completion and performance to the turnkey service provider who must build the facility to exact performance specifications for a specified price under a strict timetable.
