Contesting a decision, working under a framework and what may change once the contract runs.

  1. 1. Guide 32: Challenging a tender decision: the standstill period, debriefing and review

    A losing bidder has rights and a short clock. What the buyer must tell you, how the standstill period works, the review bodies in each country, which grounds succeed, and how to decide within days whether a challenge is worth it.

  2. 2. Guide 08: Framework agreements: how they work and how to get on one

    Frameworks decide years of public purchases in one tender. How call-offs and mini-competitions work, what the 4-year rule means, and how to win work once you're on the framework.

  3. 3. Guide 33: Contract modifications and extensions: what a buyer may change without a new tender

    Public contracts get extended, enlarged and renegotiated, but only within limits the directive sets. The de minimis rule, the fifty percent ceiling, review clauses, replacement of the contractor, and the modification notices that tell competitors what is happening.
