A turnkey project is a type of construction or service project in which the contractor or provider takes full responsibility for the design, planning, construction, and delivery of a completed project to the client. The term “turnkey” signifies that the client receives a finished product ready for use, just like turning a key to open a door.

Turnkey projects are common in various industries, including construction, real estate development, manufacturing, and information technology. They can range from building construction to software development to manufacturing facility setup.
