Documentation

Information about bids is important for many use cases, including:

  • Market analysis, to understand competition
  • Red flag analysis, to monitor corruption risk
  • Value for money analysis

This extension introduces a top-level bids object to describe individual bids and aggregate statistics.

Depending on the procedure, a bid can be an estimate, offer, proposal, quote or quotation. Regulatory regimes vary on the extent to which they allow information about bids to be proactively published, and at what point in the procurement process. In some systems and processes, a list of invited bidders is published in a tender notice, and full details on the bids received are published in an award notice. In other systems, only summary statistics, like the number of bids received, is published.

Esquema

La lista bids/details se utiliza para proporcionar uno o más objetos Bid, cada uno de los cuales representa una única oferta recibida.

The bids.statistics array is used to represent key statistical information about the number of bids and bidders. Each entry in the array is a Statistic object containing at least:

  • Un identificador
  • A measure, from the statistic.csv codelist
  • Un valor para esa medida

The statistic.csv codelist is an open codelist. Publishers can add their own codes to this list. When doing so, publishers are encouraged to engage with the open contracting community to agree upon definitions of each code.

Por ejemplo, tal vez los publicadores deseen agregar estadísticas sobre negocios pertenecientes a minorías o mujeres, u ofertas que cumplan ciertos estándares y metas ambientales.

La lista de código en la columna Categoría muestra si la estadística aplica a las ofertas u ofertantes o si esta especificado o requerido por una categoría particular del contexto regulatorio (ej. UE)

Guía

Correct a bid's value

Los compradores y entidades contratantes – y en algunas jurisdicciones, los oferentes – puden corregir el valor de una oferta después de que se envía la oferta: por ejemplo, para corregir un error aritmético o un punto decimal erróneo

En el OCDS, el valor de la oferta se publica con el campo bids.details.value . Si el valor de la oferta se corrige, el valor del campo bids.details.value queda sobreescrito. Si esto pasa, el valor original solo está disponible a través del proceso de contratación ' change history.

Como publicador, para hacer que tanto los valores originales como los valores corregidos esten disponibles para los usuarios, publique al menos dos entregas para el proceso de contratación: una entrega con el valor original de la oferta y otra con el valor corregido.

Bids submitted for multiple lots

In some cases, potential suppliers can submit bids for multiple lots. Regardless of whether the bids take the form of a single document or multiple documents, OCDS models the "bid" for each lot as a separate object, to improve interoperability.

If a potential supplier submits a bid for multiple lots as a single document, for each lot, add a Bid object to the bids.details array. Add the bid's identifier to the object's identifiers array, and add the lot's identifier to the object's relatedLots array.

If the bid cannot be divided (for example, the data source describes only the total value of the bid, and not the individual value for each lot within the bid), create one Bid object, and add all lots' identifiers to the object's relatedLots.
