The ESPD declaration that disqualifies — what Part IV demands and where bidders go wrong

It is 09:15 on a Thursday. The deadline passed eight days ago.

You are reading an exclusion notice for tender 2026/S 041-112438 — a road surface rehabilitation contract, three lots, central procurement body, northern Italy. Your firm submitted. The notice is two paragraphs. The first confirms receipt of your tender. The second states it has been found non-compliant with the selection criteria and cannot be considered for award.

No further explanation. No invitation to clarify. No appeal window flagged.

You open the ESPD XML you submitted — ESPD_Response_Rossi_Costruzioni_v3_FINAL.xml. Part IV.C. Section on works references. Three projects listed. Two inside the five-year window the notice required. One from seven years ago.

The third project was your most comparable reference. It was also outside the reference period. And you did not notice, because the field accepts any date you type.

The ESPD is not a form. It is a legal declaration with your name on it.

The European Single Procurement Document was introduced by Article 59 of Directive 2014/24/EU and given its standard form by Commission Implementing Regulation (EU) 2016/7. It replaced the old requirement to submit certificates and supporting documents at the point of tender submission. Under the ESPD system, you declare — provisionally — that you are not subject to the exclusion grounds in Article 57 and that you meet the selection criteria set under Article 58. The contracting authority takes your word for it at submission. Only the prospective awardee produces the underlying documents before award.

This is efficient. It is also dangerous if you treat the form as a formality.

The declaration is legally operative. Its content is measured against the requirements in the contract notice and procurement documents. Where it does not match those requirements — wrong figures, wrong dates, wrong qualifications — the declaration fails on its own terms. The underlying reality of your capacity does not rescue you. What counts is what you declared, and whether the declaration is consistent with what was asked.

What Part IV actually contains

Part IV divides into four substantive sections and one shortcut.

Section IV.A — Suitability. This covers professional and trade register enrolment. For construction in most Member States, this means being registered in the relevant professional or commercial register — the CCIAA in Italy, the KRS in Poland, the Handelsregister in Germany. The contracting authority specifies which registers apply. If you are not registered where required, you declare “no.” If you declare “yes” without checking, you create a discrepancy that surfaces at the document verification stage.

Section IV.B — Economic and financial standing. This is where turnover figures live. Contracting authorities typically require a minimum annual or average turnover — often expressed as a multiple of the estimated contract value — calculated over a specified number of financial years, usually the last three. The notice will say “minimum average annual turnover of EUR 2,000,000 over the last three financial years.” Your Part IV.B declaration must match that specific window and that specific figure or exceed it.

Section IV.C — Technical and professional ability. The most error-prone section. Works references, key personnel qualifications, technical equipment declarations, and educational or professional certifications all sit here. For works contracts, the reference period is typically the last five years, though contracting authorities may set a shorter window. They may also require that referenced works be of comparable nature and size — the notice language usually includes both conditions.

Section IV.D — Quality assurance schemes and environmental management standards. ISO 9001 certification, EMAS registration, or equivalent. Often required but frequently overlooked until late in the preparation process. If the notice requires it and your certificate has lapsed, you cannot declare compliance.

The alpha shortcut and when it backfires

Section α (alpha) of Part IV is a global option. A contracting authority that has activated it allows bidders to make a single declaration: yes, I meet all the selection criteria described in the contract notice and procurement documents. No individual fields in IV.A through IV.D need to be completed.

This sounds efficient. It creates a specific failure mode.

Alpha works only when the contracting authority has embedded all its selection criteria fully and precisely in the published tender documents. When the CA has done this correctly and activates alpha in its ESPD request, a bidder who completes alpha correctly shifts the verification work entirely to the post-selection document stage. That is the intended design.

The problems arise in two ways. First: a bidder selects alpha when the contracting authority has not activated it. The ESPD is returned with a global declaration but none of the specific field data the evaluation committee expected to find. This is an incomplete response, not a completed one. Second: a bidder selects alpha when the CA has activated it, but has not actually read what the tender documents say the criteria are. The declaration covers requirements the bidder has not verified it meets. At document verification, the evidence does not support the declaration.

Alpha is not a way to save time on a complex bid. It is a way to shift verification to a later stage — and only when the procedural prerequisites are met.

Where Part IV.C goes wrong in practice

Works references are the most common source of Part IV failures in construction tenders. Three patterns account for most of them.

The date boundary problem. The notice requires works completed in the last five years. You cite three projects. Two fall inside the window. The third — your most relevant — was completed six years ago. You include it because it is comparable and demonstrates capability. The contracting authority excludes it from consideration. If the two remaining references do not meet the minimum requirements alone, your bid fails the selection stage. The field did not reject the date. The evaluation committee does.

The comparability mismatch. The notice specifies “works of comparable nature and size” — a phrase with real content. If the contract is for bridge rehabilitation at EUR 4 million and your references are road surfacing contracts at EUR 800,000, the comparability condition may not be satisfied even if the dates are right. The ESPD does not prompt you to check this. You have to read the notice.

The key personnel gap. Part IV.C may require declaration of the qualifications of personnel who will be assigned to the contract — a site manager with a specific professional registration, a structural engineer with minimum years of relevant experience. If the person you declare does not hold the qualification the notice requires, or if their CV as attached does not clearly evidence it, the declaration is incomplete. Submitting a CV in the wrong language for the Member State also produces this failure — the evaluator cannot verify what is not readable.

The common thread: Part IV.C is only as good as your reading of the contract notice. The ESPD form is neutral. It accepts whatever you put in it.

What happens when Part IV is defective

Here the picture is more nuanced, and the nuance matters for how you respond to a defect notice.

The Court of Justice of the European Union addressed the correction question in Case C-599/10 (SAG ELV Slovensko). The Court held that EU law does not preclude contracting authorities from asking tenderers to clarify or correct obvious or clerical errors in a tender — but the correction must not in substance amount to the submission of a new tender.

This creates an asymmetric rule. If your Part IV.B shows a turnover figure that is clearly a typographical error and the underlying financial statements show the correct higher figure, a contracting authority may — not must — request clarification. They are not obliged to. If they do, and you can point to a pre-existing document that resolves the discrepancy, the clarification may be accepted.

What cannot be corrected: a missing works reference. A turnover figure you would now like to replace with a higher one from a different financial year. A key personnel qualification you did not declare at submission but which exists. These are not clarifications. They change the substance of the declaration. They are, in the language of the case law, new tender submissions disguised as corrections.

Some Member States’ courts and review bodies have also found that the absence of a separate ESPD from a capacity-reliance subcontractor — required under Article 63 — is a remediable irregularity rather than a fatal defect. But this turns on national transposition and the specific wording of the procurement documents. Do not plan around the correction option. Plan to get it right at submission.

e-Certis and the verification stage

When you reach document verification — as prospective awardee, under Article 60 — the contracting authority will specify what supporting documents it requires for each Part IV section. For cross-border bids, e-Certis provides a reference mapping of what each Member State accepts as proof: professional register extracts, financial statements, tax compliance certificates, works completion certificates.

e-Certis is useful. It is not legally binding. The contracting authority accepts what it accepts. Apostille requirements, certified translation requirements, and document validity periods are set nationally and may not be fully captured in the e-Certis database. Use e-Certis to build your document list, then verify the specific requirements with the contracting authority’s published guidance or direct pre-procurement question.

Before you submit

Part IV is not a section to complete by memory. It is a section to complete by reference to the contract notice — criterion by criterion, figure by figure, date by date.

Open the notice. Find the selection criteria section. Write down the specific turnover threshold, the reference period in years, and the comparability requirements for works. Then open Part IV of your ESPD. Match them.

Check the reference period for every project you cite. Check that the dates of completion — not commencement — fall within the window. Check that the declared contract values match the completion certificates you will produce if asked.

If the contracting authority has activated the alpha option, confirm that before using it. Read what the tender documents say the criteria are. If anything is ambiguous, submit a clarification request through the platform before the deadline.

Steinlog’s tender library surfaces the selection criteria from the notice alongside the ESPD checklist, which reduces the chance of the date-boundary error that costs bids after weeks of preparation.

The ESPD is preliminary evidence. The legal weight it carries is not preliminary. A defective Part IV does not invite a conversation. It produces an exclusion notice.

Read the notice. Match the fields. Check the dates.
