Turnkey refers to a project or system that is complete and ready for immediate use with no additional work or modification required. A turnkey project involves a contractor taking responsibility for both the design and construction of a facility that is handed over to the client in a ready-to-operate condition. Turnkey projects allow companies to establish operations in foreign countries by building entire plants, but they also carry risks like revealing trade secrets. Common examples include turnkey hospitals, industrial plants, and computer packages with pre-installed software and hardware. L&T has extensive experience providing turnkey solutions internationally, with ongoing projects in countries like Sudan, Australia, and Maldives.
