A turnkey project or contract described by Duncan Wallace (1984) is: Turnkey refers to something that is immediately operational and is generally used for the sale or delivery of goods or services. The word is an indication that the customer, after receiving the product, must simply turn the contact key to make it operational, or that the key must be handed over to the customer.  Turnkey is often used in the construction industry, for example when it comes to the pooling of materials and work by the builder or general contractor to complete the house without the owner`s involvement. The word is often used to describe a house built on the developer`s land, with developer funding ready to move in for the client. When a contractor builds a “turnkey house,” he frames the structure and finishes the interior; It`s all over to the cabinets and carpets. Turnkey is also commonly used in motorsport to describe a car that is sold with a powertrain (engine, gearbox, etc.) unlike a vehicle that is sold without a vehicle, so that other components can be reused. A turnkey computer system is a complete computer with hardware, operating system and applications specially designed and sold for certain commercial requirements. The key-in-hand term is more or less synonymous with “design and construction,” “package contact” and “design contractors.” These are the most popular types of contract management system in the large construction industry. Orgalime has published a new standard contract – Orgalime`s turnkey contract for industrial work – our most comprehensive publication to date. Similarly, this term can be used to promote the sale of an established business, including all equipment needed for operation or by a business provider that provides complete packages for business creation.
 An example would be the creation of a “turnkey hospital” that would create a complete medical centre with medical equipment installed. A turnkey project or turnkey process (also written turnkey) is a type of project designed to be sold to any buyer as a final product. This runs counter to the Build-to-Order in which the designer builds an item to the precise specifications of the buyer or when an incomplete product is sold on the assumption that the buyer would finalize it. The volume of private sector investment is generally small and short-term. This type of agreement generally does not provide a strong incentive to conclude a project at an early stage. This type of private sector involvement is also called design construction. The following figure shows the typical structure of a turnkey contract. Why this new standard contract? First, because the scope of the terms and conditions and standard contract forms had to be fulfilled by a turnkey contract for the supply of complete industrial facilities or facilities. These are often complex facilities and work; Contracts must therefore be both flexible and comprehensive. Buyers and contractors of mechanical engineering who have used existing models have generally not adapted them well to their needs: they are often less designed for industrial work than for civil engineering contracts that are very complex and sometimes very one-sided. The term turnkey is also often used in the technology sector, most often to describe prefabricated computer “packages” in which everything is needed for a particular type of task (for example.
