There are various management models depending on the instrument through which the contracting is carried out, and the following can be distinguished:

Management of framework agreements, dynamic purchasing systems, based contracts, and specific contracts:

• The contracting authority of a framework agreement (FA) or a dynamic purchasing system (DPS) is the Centralized Contracting Board, although its powers have been delegated to the Directorate General for Rationalization and Centralization of Contracting (DGRCC), except those related to award decisions. Therefore, the DGRCC is responsible for formalizing the FA or DPS with the awarded companies or those admitted to the DPS, making the necessary modifications, imposing penalties, etc.

The FA and DPS do not involve an expenditure file, as this is not defined until a based or specific contract is executed.

• Regarding based and specific contracts, the contracting authority is the DGRCC, except in the case of affiliated entities, where the general rules of the entity apply.

In general, it is the responsibility of the recipient body to determine the needs to be met through the contract and, when necessary, to call a second tender to award the contract, carrying out all actions prior to the award. Once the required procedures have been completed, the recipient body of the supply or service will propose the award of the corresponding contract to the DGRCC.

Based and specific contracts involve an expenditure file that must be processed by the recipient body of the contracted service or supply, which is also responsible for receiving and paying for the contracted service.

Award proposals are processed through the Conecta-Centralización application, and in the specific case of the electricity FA, an additional application called ELECTRA has been developed to facilitate the management of its based contracts.

With this management model, savings directly benefit the budgets of the requesting bodies.

Management of centralized contracts with centralized budget in section 10:

The contracting authority is the Centralized Contracting Board, although its powers have been delegated to the Directorate General for Rationalization and Centralization of Contracting (DGRCC), except those related to award decisions. Therefore, the DGRCC is the competent authority for formalizing the contract, as well as for its modifications, imposition of penalties, extensions, termination, etc.

From an economic-financial perspective, the powers for approval and commitment of expenditure belong to the head of the DGRCC, while the powers for recognizing obligations and payment proposals are delegated to the bodies designated by each department or entity included in the centralized contract, except in the case of the centralized telecommunications contract, which is delegated to the General Secretariat for Digital Administration of the Ministry of Economic Affairs and Digital Transformation, and the contract for ex post evaluation of the effectiveness of institutional advertising campaigns, where these powers have not been delegated.

From the perspective of contract execution, the departments and entities included in the contract are responsible for approving the services or supplies covered by the contract and the invoices, allowing for a decentralized management of the contract linked to the responsibility of supervising its execution by the recipient bodies.

These centralized contracts include Social Security entities that have their own funds to finance the centralized contracts and are also responsible for monitoring the execution of the contract.

Management of centralized contracts without budget centralization:

In the case of the centralized travel agency service contract, the funds have not been centralized in section 10, so each managing center must pay for the services from its own budget.
