Key Takeaways
VOB/A EU regulates public construction contracts above the EU threshold of 5.538 million euros
Open and restricted procedures are the standard procurement types under § 3 EU VOB/A
Electronic communication (eVergabe) is mandatory for all Europe-wide construction tenders
The minimum deadline for bid receipt in the open procedure is regularly 35 days
Introduction
From an estimated contract value of exactly 5.538 million euros, EU procurement law strictly applies to public construction contracts (EU Commission Threshold Regulation, as of 2024). For you as a bidder, this means the rules of the game change fundamentally. VOB/A EU requires stricter deadlines, mandatory electronic communication, and Europe-wide transparency. This guide is aimed at Bid Managers and managing directors of construction companies who want to win these complex procedures.

Frequently Asked Questions About VOB/A EU
When Does VOB/A EU Apply to Your Construction Contracts?
The VOB/A EU thresholds define the boundary between national and European procurement law. As soon as a construction project reaches or exceeds the threshold of 5.538 million euros (European Commission, 2024), the contracting authority must issue a Europe-wide tender. For you as a bidder, this means you must prepare for a formalized process under the Act Against Restraints of Competition (GWB) and the Procurement Ordinance (VgV).
Criterion | National Procurement (VOB/A) | Europe-Wide Procurement (VOB/A EU) |
|---|---|---|
Threshold | Under EUR 5.538 million | From EUR 5.538 million |
Legal Framework | Budget law, VOB/A | GWB, VgV, VOB/A EU |
Publication | National (e.g., bund.de) | Europe-wide (TED) |
Bidder Pool | Regional / National | Entire EU single market |
Tip: For lot-based awards, check the so-called 20 percent quota rule under § 3 (9) VgV. Contracting authorities may award up to 20 percent of the total value nationally if the individual lot is under 1 million euros.
The exact calculation of the contract value determines the applicable procurement law.
How Do Open and Restricted Procedures Differ?
The VOB/A EU procedure types dictate how you submit your bid. Under § 3 EU VOB/A, the contracting authority has equal access to the open procedure and the restricted procedure.
In the open procedure, any interested construction company can submit a bid. In the restricted procedure, a preliminary qualification stage takes place. Here, you initially submit only your qualification documents. According to a 2023 analysis by the Bundeskartellamt, contracting authorities use the restricted procedure for complex construction projects in 65 percent of cases to limit the number of bidders to usually three to five suitable companies.
For you as a bidder, this changes your strategic preparation. In the open procedure, you must calculate the complete bid immediately. In the restricted procedure, you focus first on your references and economic capacity.
The choice of procedure type dictates your time and personnel effort.
Which Deadlines and Formal Requirements of VOB/A EU Must You Observe?
VOB/A EU deadlines are strict and non-negotiable. Late receipt leads to the mandatory exclusion of your bid under § 16 EU VOB/A.
In the open procedure, the regular bid deadline is at least 35 days from the dispatch of the contract notice (according to § 10a EU VOB/A). With electronic transmission, the contracting authority can shorten this deadline by five days. In the restricted procedure, you have at least 30 days for the request to participate and subsequently another 30 days for the actual bid.
In addition, eVergabe is mandatory. You must submit all documents via procurement portals. According to the KOINNO Report 2024, 12 percent of bids fail due to formal errors in the electronic signature or incomplete uploads.
Strict deadline management secures your participation in the procurement procedure.
VOB/A EU Bid Creation in Four Phases for Bid Managers
VOB/A EU bid creation requires a structured process. If you consistently run through these four phases, you minimize formal errors and increase your chances of an award.
Phase 1: Review the Tender and Make a Bid/No-Bid Decision
Analyze the procurement documents immediately after publication. Check the knockout criteria and the required references. The bid/no-bid decision must be made within the first three days. Through structured processes, the HR service provider YER was able to accelerate its bid decisions by 90% (from three days to a few hours).
Phase 2: Ask Bidder Questions Strategically
Identify ambiguities in the bill of quantities or the VOB/B contract conditions. Submit bidder questions early via the procurement portal. Procurement law forces the contracting authority to answer all questions anonymously to all bidders.
Phase 3: Prepare Qualification Documents and Concepts
Compile the required documents. This is where the difference between generic AI and domain-specific AI becomes apparent. While generic AI like ChatGPT often remains imprecise with complex construction references, domain-specific AI extracts the exact qualification requirements from the procurement documents and matches them against your internal database. The AI analyzes the required criteria and creates a rough draft. The Bid Manager then decides on the final wording and strategic direction.
Phase 4: Calculation and Electronic Submission
Calculate the prices in the bill of quantities (usually GAEB format). Check all documents for completeness before uploading.
A standardized process prevents formal errors in the bid phase.
How Do You Master the Qualification Check and Award Criteria Under VOB/A EU?
The evaluation of your bid takes place in two separate stages: the qualification check and the evaluation of the VOB/A EU award criteria.
The qualification check (§ 16b EU VOB/A) clarifies whether your company is competent and capable. Revenue figures, employee base, and comparable reference projects from the last five years count here. If a required document is missing, the contracting authority can request it later—but they are not strictly obligated to do so for every document type.
The award criteria (§ 16d EU VOB/A) determine the most economically advantageous bid. Alongside price, qualitative aspects are often factored in. According to a 2023 study by the German Procurement and Contract Committee (DVAL), qualitative criteria account for an average of 40 percent of the total score in complex construction projects. These include the qualifications of the site management team and modern construction methods. You must precisely demonstrate in your bid how you meet these criteria.
Check your reference database for completeness before the next procedure.
Checklist: VOB/A EU
Check threshold: Is the contract value over EUR 5.538 million?
Identify procedure type: Open or restricted procedure?
Note deadlines: Block the submission deadline for the request to participate or bid in the calendar.
Make bid/no-bid decision: Check knockout criteria within three days.
Collect qualification documents: Prepare references and revenue figures according to § 16b EU VOB/A.
Analyze award criteria: Evaluate the weighting of price and quality (e.g., 60/40).
Test eVergabe upload: Verify signature cards and portal access before the deadline expires.
How Forgent Approaches This
The manual review of extensive construction tenders and the compilation of qualification documents cost Bid Managers countless hours. As a domain-specific AI platform for tenders, Forgent covers the entire process: from finding and evaluating to applying and managing. The system analyzes procurement documents with over 10,000 pages and 50 files in a few minutes, allowing you to massively accelerate the bid/no-bid decision. You still make the final decision on participation and calculation.
Frequently Asked Questions About VOB/A EU
What is the difference between VOB/A and VOB/A EU?
VOB/A regulates national construction procurement below the threshold. VOB/A EU (Section 2 of VOB/A) applies to Europe-wide tenders from a contract value of 5.538 million euros (as of 2024). It contains stricter requirements for deadlines, transparency, and mandatory electronic communication.
Can a VOB/A EU deadline be extended?
Yes, but only under certain conditions. If the contracting authority makes significant changes to the procurement documents or fails to provide additional information in a timely manner, they must appropriately extend the bid deadline under § 10a EU VOB/A.
Which documents are mandatory for the qualification check?
That depends on the respective contract notice. By default, contracting authorities request the European Single Procurement Document (ESPD) or specific evidence of economic and financial capacity (e.g., balance sheets) as well as technical capacity (e.g., reference projects from the last five years).
