Documentación

Bajo algunas reglas y procesos de compras públicas, para extender el valor o duración del contrato, o para hacer grandes cambios, se requiere firmar un nuevo contrato.

Este nuevo contrato forma parte de el mismo proceso de contrataciones así como el contrato antiguo que esta extendiendo

In these cases, the extendsContractID field can be used to identify that a given entry in the contracts array should be understood as related to a previous contract.

Use this extension only if there is a substantive new contract signed as the extension of a previous contract. In most cases, an update to the value or duration of a contract should be modelled as an amendment within a single entry in the contracts array.

Ejemplo

El extracto más abajo muestra tres contratos en la matriz de contratos en un release OCDS.

Los primeros dos contratos se firmaron en 2011: uno por cada año de renta de la propiedad, y otro por dos años de servicios relacionados con la propiedad rentada.

The third contract was signed in 2012, and renews the property rental for another year. This is related back to the contract for the first year of rental with the extendsContractID field.
