DC1, DC2, DUME: the documents that get your bid rejected on a technicality

Your technical proposal is excellent. Your price is competitive. But your DC2 has an inconsistency with your DC1: bid rejected on a technicality. Every year, SMEs lose contracts not for lack of competence, but for administrative errors on a form.

What administrative documents are required for a public tender? The mandatory administrative documents for French public procurement include: DC1 (application letter), DC2 (candidate declaration), DUME (European Single Procurement Document, mandatory above EU thresholds), insurance certificates, company registration extract (Kbis) less than 3 months old, tax and social security certificates, and DPGF (Breakdown of Overall Fixed Price). An error or omission leads to bid rejection for inadmissibility.

DC1 — Application Letter

Official application identifying the candidate or group. Information: company ID, consultation object, lots targeted, signature.

Common error: forgetting group type checkbox or missing lead signature.

DC2 — Candidate Declaration

Financial, technical, and professional capabilities declaration. Revenue (3 years), headcount, equipment, similar contract references, certifications.

Common error: outdated references (>5 years) or irrelevant to target contract.

DUME — European Single Procurement Document

Standardized European sworn statement replacing DC1/DC2 above EU thresholds. Reusable across contracts.

Common error: generic DUME without contract-specific adaptations.

DPGF and DQE — Pricing Documents

DPGF: flat-rate price breakdown by item. DQE: estimated quantities for framework contracts.

Common error: calculation errors or subtotal/total inconsistencies.

Commitment Act (AE)

Contractual commitment document with your price offer.

Common error: price inconsistency between AE and DPGF/BPU.
