What is a duplicate tender?

The term duplicate tender covers various situations in which a service is tendered more than once, leading to inefficiencies, distortions of competition or legal problems. The most common cases are:

1. Parallel tender: Two contracting authorities tender the same service simultaneously (e.g. in cooperations without coordination).
2. Repeat tender: After a procurement procedure has been cancelled, the same project is tendered again.
3. Overlapping tender: Two procurement procedures by the same authority cover the same subject matter.
4. Precautionary duplicate tender: The authority tenders the same contract in two procedures in order to have a "backup".

Problems under procurement law

Duplicate tenders without objective justification are problematic under procurement law. They may:

• Distort competition (tenderers do not know which procedure will prevail)
• Breach the principle of equal treatment
• Lead to contradictory contractual obligations on the part of the authority
• Tie up tenderers' resources unnecessarily
• Cause budgetary-law problems

Permissible repeat tender

Repeating a tender after lawful cancellation of the first procedure, by contrast, is permitted and is provided for in procurement law. Where a procurement procedure is lawfully cancelled (e.g. because no economically acceptable tender was received or the need has changed), the contracting authority may launch a new procedure. It is not obliged to keep the specifications unchanged.

Distinction: division into lots

Division into lots is not a duplicate tender. Where a contracting authority divides a larger overall service into several lots and tenders these separately, this is a permissible — and often required — practice under procurement law.

FAQ

Is a precautionary duplicate tender permitted? Generally no. The contracting authority may not simultaneously run two procedures for the same contract, as this leaves tenderers uncertain about the actual procurement target and wastes resources.

What happens if two overlapping tenders are inadvertently run? The contracting authority must cancel one of the procedures. Awards already made may have complicated contractual consequences.

Can a tenderer challenge a duplicate tender? Yes, where the duplicate tender causes harm or breaches the principle of equal treatment.
