Procurement Procedures

Clarification in Procurement Law

Procedure where the contracting authority asks bidders to explain unclear or unusual bid components.

What is Clarification in Procurement Law?

Clarification (German: Aufklärung) in procurement law refers to the procedure where the contracting authority asks a bidder to explain certain bid components in more detail. This may relate to prices, technical solutions, calculation bases, or other bid aspects. Clarification serves proper bid review and must be strictly distinguished from prohibited post-tender negotiation.

Legal Framework

  • § 60 VgV: Clarification of bid content — central provision
  • § 15(5) VgV: Prohibition of negotiations in open and restricted procedures
  • § 44 UVgO: Clarification of price appropriateness below thresholds
  • § 16d(1) No. 2 VOB/A: Clarification for construction procurements

Clarification vs. Negotiation

Clarification (permitted)Negotiation (prohibited)
Explaining existing bid componentsChanging bid content
Resolving ambiguitiesPrice negotiation
Demonstrating price calculationPost-hoc improvement
Explaining technical solutionsIntroducing new service elements

Triggers for Clarification

1. Abnormally low tenders (§ 60 VgV): The most common trigger. Required when the bid price is significantly below competitors (rule of thumb: more than 20% below the next bid). The bidder must demonstrate a sustainable calculation.

2. Technical clarification: Unclear product specifications, deviations from standards, use of alternatives.

3. Suitability-related clarification: Unclear references, personnel capacity questions.

4. Formal clarification: Obvious typos (e.g., decimal errors in prices), contradictory information.

Clarification Process

  1. Request: Authority requests clarification in writing
  2. Deadline: Reasonable deadline (typically 3-7 business days)
  3. Response: Bidder explains the points requiring clarification
  4. Meeting: Optional oral discussion (§ 15(5) VgV)
  5. Assessment: Authority evaluates the explanation
  6. Decision: Bid remains or is excluded

Consequences

Successful clarification: Bid stays in evaluation; results become part of the procurement report.

Failed clarification: Prices cannot be plausibly explained — exclusion (§ 60(3) VgV). Technical solution fails requirements — exclusion. No response — possible exclusion.

Important for Bidders

  • Keep calculation documentation ready
  • Explain openly why your price differs
  • Always meet deadlines for clarification requests
  • Do not modify your bid during clarification
  • Document all communication carefully
