Documentation

Information on bids submitted as part of a contracting process is important for many forms of analysis, including:

  • Market analysis for understanding the competitiveness of a given marketplace;
  • Red flag analysis for understanding potential corruption risks; and
  • Value for money analysis;

Regulatory regimes vary on the extent to which they allow information on bidding to be proactively published, and at what point in the procurement process. In some systems and processes, a list of invited bidders is published at the start of tendering, and full details and documents on the bids received are disclosed when evaluation is complete. In other systems, only summary statistics on the number of bids received is made public.

The OCDS bid extension introduces a new, flexible, top-level section to each contracting process to capture bidding information. Implementers will need to assess which fields are applicable to their local regulatory regime, and to local use-cases.

Schema

The bids.details array is used to provide one or more Bid objects, each representing a unique bid received.

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 BidsStatistic object containing at least:

  • An identifier
  • A measure, from the bidStatistics.csv codelist
  • A value for that measure

The bidStatistics.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.

For example, publishers may wish to add statistics on minority or women-owned businesses, or bids that meet certain environmental standards and targets.

The codelist's Category column indicates whether the statistic applies to bids or bidders or whether it is specified or required by a particular regulatory context (e.g. EU).
