Procurement Procedures

Restricted Procedure

The restricted procedure is a procurement method where the contracting authority invites a limited number of companies to submit tenders after a public call for participation.

What is a Restricted Procedure?

The Restricted Procedure (German: Nichtoffenes Verfahren) is a two-stage procurement procedure governed by § 16 VgV (above EU thresholds) and § 3a EU VOB/A (for construction works). Unlike the open procedure, it follows two distinct phases: a pre-qualification stage and the actual bidding phase.

When is the Restricted Procedure Used?

The restricted procedure is preferred for:

  • Complex projects where only technically qualified companies can submit meaningful bids
  • Security-sensitive procurements, such as defense or critical infrastructure
  • Contracts with high technical requirements, where pre-selection ensures bid quality
  • Situations expecting many bidders, to limit evaluation effort

The Two-Stage Process

Phase 1 – Participation Competition: The authority publishes a notice inviting companies to submit participation requests. Eligibility criteria – such as references, turnover, technical staff, or equipment – are defined in advance. At least five suitable candidates must be invited to bid (§ 51 VgV).

Phase 2 – Bidding Phase: Only selected candidates receive tender documents and may submit bids. Award criteria follow the most economically advantageous tender principle.
