To launch a procurement procedure, tender documentation has to be prepared and the exclusion, selection and award criteria that are the basis for the contract award decision must be defined. The tender documentation (in addition to the technical specifications) explains the administrative requirements of the procedure, justifies the estimated value of the contract, and specifies the terms and conditions under which tenders are to be submitted, evaluated and awarded. They may include other elements such as draft contract provisions, cancellation conditions for the tender, as well as modifications, performance and termination provisions, etc.
