A framework agreement is a good way to cooperate with public authorities. Once approved and compliant with the EU, it can be credible to ensure future work in the public sector, both through a framework and an individual project contract. In many cases, a framework agreement is a way for the adjudicator to establish a framework document for its suppliers. This means that there is no need to offer more than once. The advantage for businesses is that once you have a place in the agreement, you will have access to a large amount of potential work, the specified amount being expected. However, it is customary for a buyer to «recover» work packages through call contracts, mini-competitions or even, if necessary, another tendering procedure, which is described in the award criteria. In the public sector, there are a number of central public procurement entities whose objectives are the creation and management of framework agreements in line with EU procurement directives  and which are available for use by designated public bodies. In the United Kingdom, for example, crown commercial service, municipal consortia such as Eastern Shires Purchasing Organisation (ESPO) and Yorkshire Purchasing Organisation (YPO) and consortia, in the areas of higher education and training: APUC (in Scotland), Crescent Purchasing Consortium (CPC),  London Universities Purchasing Consortium (LUPC), North Eastern Universities Purchasing Consortium (NEUPC),  North Western Universities Purchasing Consortium (NWUPC)  A framework is required for the construction of standard construction units or office space on different sites over a four-year period. The Official Journal of the European Union and the selection procedure, based on financial and economic capacity and technical capacity, provide a framework for a number of major contractors on the basis of «the most economically advantageous offer». Each of the major contractors has the capacity and supply chains to carry out the various aspects of the construction work during the period.
With each call, we decide whether a mini-competition is necessary depending on the fine-tuning of the conditions.
