Opening of calls for tenders. The university cannot open a mini-competition before the expiry of the application period. The call must be awarded on the basis of the best bid, in accordance with the award criteria defined when the framework was set up. However, the weightings of the award criteria may vary in order to take account of the importance of the specific criteria for the requirement covered by the proposed call, provided that this is notified to suppliers in the context of the call for tenders. A framework agreement is needed to cover the paper needs of a number of authorities over a four-year period. Following the opinion of the Official Journal of the European Union and the selection procedure based on financial and economic capacity and technical capacity, tenders are evaluated on the basis of `economically the most advantageous` for accession to the framework. A number of suppliers are included in the framework to provide a variety of pulps, simple, fed, recycled, colored, etc. – over a period of four years. The power is conferred on the supplier in the context where, on the basis of the initial award criteria, the tender is the “most economically advantageous” for each call required during the four years. Since it is not necessary to refine or supplement the conditions in this case, it is not necessary for the Authority to use the mini-competition option.
The duration of individual calls is not in line with the duration of the framework agreement, but may be shorter or longer, where appropriate. The university may set the duration of individual contracts on the basis of a framework agreement, taking into account factors such as the time required for their execution, where the maintenance of equipment with an expected lifespan or more than four years is included or where full staff training is necessary for the performance of the contract. In November 2018, the Civil Engineering Contractors Association (CECA) published a study that indicates that managers do not provide the work contractors expect and induce them to make unnecessary efforts. Describing efforts to reach an agreement between Israel and Palestine, Senator George J. Mitchell said that if the frameworks are not used in the manner intended or described in the Buyer`s guide, it is possible that the university could be subject to an “inefficiency order” against the appeal contract. Any contract resulting from the misuse of a framework contract, for example. B the appeal of a framework in which the university has not been designated as a party to that framework or a substantial derogation from the fixed conditions of revocation, would be regarded as a direct award confirming the risk of an order of inefficiency. In the public sector, there are a number of central purchasing bodies which aim to draw up and manage framework agreements in line with EU public procurement directives  and are available to designated public bodies. In the United Kingdom, these are Crown Commercial Service, local consortia such as the Eastern Shires Purchasing Organisation (ESPO) and the Yorkshire Purchasing Organisation (YPO) as well as consortia, which operate in the higher education and training sector: APUC (Scotland), Crescent Purchasing Consortium (CPC),  London Universities Purchasing Consortium (LUPC), North Eastern Universities Purchasing Consortium (NEUPC),  North Western Universities Purchasing Consortium (NWUP) C),  and Southern Universities Purchasing Consortium (SUPC).
 There may be some commodity sectors where there are many framework agreements. . . .
