“Turnkey construction” refers to a type of construction project where the contractor is responsible for the entire process, from design and planning to construction and final delivery. The key feature of a turnkey project is that the owner or client receives a completed building or facility that is ready for use, often with minimal involvement required from them beyond initial specifications. The term “turnkey” comes from the idea that once the project is completed, the owner can simply “turn the key” to start using the facility.
