Tender Documents

Tender documents (German: Vergabeunterlagen) are the complete set of documents that a public contracting authority provides to bidders within a procurement procedure. They are the central working tool of every public tender: on their basis, companies decide whether to bid, calculate their offer and assess the risks of the future contract. Anyone who does not fully understand the tender documents cannot submit an evaluable bid – formal errors, missing evidence or incorrectly completed forms regularly lead to exclusion.

Tender documents must be clearly distinguished from the contract notice. The notice is the public "profile" of the contract with the key parameters – subject matter, CPV code, procedure type, deadlines and the internet address at which the actual tender documents can be accessed. The tender documents themselves then contain all the detail a bidder needs for a complete offer.

Components of tender documents

In the above-threshold range, the composition is laid down by law. Under § 29 VgV, tender documents consist of three building blocks:

• Cover letter – in particular the invitation to submit requests to participate or tenders. It explains what is to be submitted, how and by when.
• Application conditions – the description of the details of how the procedure is conducted, including the suitability and award criteria. These are the formal rules: required forms, submission route, permitted file formats, structure of the bid.
• Contract documents – these in turn consist of the specification (what is to be delivered) and the contract terms (on what conditions).

In practice the package is larger and additionally contains:

• the bill of quantities as the item-by-item, constructive form of the specification – the core in construction, exchanged via GAEB data exchange;
• general and special contract conditions (e.g. VOL/B, VOB/B), liability and penalty clauses, payment and acceptance terms;
• required eligibility evidence and forms relating to the eligibility criteria – self-declarations, references, turnover figures, certificates;
• the award criteria with the evaluation matrix and weighting;
• standard forms such as the bid letter, price sheets and, where applicable, subcontractor commitment declarations.

Where to obtain tender documents

Since the e-procurement mandate, tender documents are provided almost exclusively in electronic form via procurement platforms. The address for access is stated in the contract notice, and access must be free of charge and complete. A mere registration requirement just to download the documents is not permitted – registration may only be required for active participation (bidder communication, bid submission). With Patterno, tender documents are consolidated automatically from the 180+ connected portals; key parameters such as deadlines and subject matter are extracted and structured into the dashboard via document extraction.

The requirements for tender documents vary by type of contract and threshold but everywhere follow the same core principles of procurement law: transparency, equal treatment and competition (§ 97 GWB).

Composition – § 29 VgV. For supply and service contracts above the EU thresholds, § 29 VgV defines the components conclusively: cover letter, application conditions, and contract documents consisting of the specification and the contract terms. The tender documents must contain all information necessary to enable interested parties to decide on their participation. For construction works, § 8 EU VOB/A contains the parallel rule.

Provision – § 41 VgV. § 41(1) VgV is the heart of electronic provision: the authority states in the contract notice an electronic address at which the tender documents can be accessed free of charge, without restriction, completely and directly – from the day the notice is published. § 41(2) VgV permits only narrowly defined exceptions (e.g. for file formats not generally available or special security requirements); in these cases the bid deadline is generally extended by five days.

Additional information – § 20 VgV. If a company requests further information on the tender documents in good time, the authority must provide it at the latest six days before the end of the bid deadline (four days in accelerated procedures). Crucially, all companies must be able to take note of the information and changes – answers to a bidder question are therefore shared anonymously with all bidders and become part of the tender documents.

Deadlines. In the open procedure, § 15 VgV sets a bid deadline of at least 35 days from dispatch of the notice; where electronic submission is accepted it can be reduced to 30 days, and in urgent cases down to 15 days. Material changes to the tender documents require a corrigendum and, as a rule, an extension of the deadline to preserve equal treatment.

A hospital network tenders the supply and maintenance of infusion pumps over four years. Estimated contract value: €1.8 million net – so an EU-wide open procedure with a TED notice.

The contract notice states the internet address of the state procurement platform. The complete tender documents are available there for free download. A medical-technology manufacturer finds the tender on the day of publication via its Patterno profile; the deadlines and subject matter have already been extracted from the documents.

Reviewing the components. The bid manager downloads the package and sorts it according to § 29 VgV:

• Cover letter – invitation to bid, 40-day bid deadline, electronic submission via the platform.
• Application conditions – required forms, eligibility criteria (three comparable hospital references, minimum turnover €2 million, ISO 13485), award criteria (price 60%, technical quality 30%, service 10%).
• Contract documents – specification with technical requirements plus a framework contract with response times, availability guarantee and penalties for downtime.

Bidder question. It is unclear in the eligibility evidence whether the manufacturer's CE certificates suffice or whether additional declarations of conformity are needed. The manufacturer submits a bidder question; the answer is officially shared with all bidders and thereby supplements the tender documents.

Review. Using automatic document extraction, the team checks every mandatory item against a checklist: no missing forms, all evidence planned, penalty clauses factored into pricing. This avoids overlooking an evaluation-relevant detail among several hundred pages – the most common cause of formal exclusions.

Bid. The fully assembled offer is submitted electronically via the platform on time – encrypted until the bid opening.

Tender documents are extensive, formally strict and spread across several files – mishandling them is the most common cause of avoidable exclusions. Five typical pitfalls:

• Reviewing the documents incompletely. Anyone who only opens the bill of quantities and skims the application conditions, draft contract or supplementary annexes regularly misses mandatory evidence, formal deadlines or liability-relevant clauses. Every document in the package is binding.
• Completing required forms incorrectly or not at all. Missing self-declarations, unsigned bid letters or empty price sheets lead to exclusion. Whatever the application conditions require must be delivered exactly and completely.
• Asking bidder questions too late. Anyone who raises ambiguities only just before the deadline risks getting no answer – the authority only has to provide additional information up to six days before the deadline (§ 20 VgV). Clarify ambiguities early via a bidder question.
• Ignoring answers and corrigenda. Answers to bidder questions and subsequent changes become part of the tender documents. Anyone who overlooks a corrigendum or an amended annex calculates on an outdated basis.
• Slipping in your own terms. Changes to the contract terms, reservations or your own standard terms in the bid render it non-evaluable. Tender documents must be accepted as given; criticism belongs in a bidder question or a challenge, not in the bid.

Professional bidders treat tender documents as a project with a clear process – not as obligatory reading just before submission. Five recommendations:

• Build a completeness matrix. Right after download, transfer all required documents, forms and evidence into a checklist and assign an owner to each item. This keeps it traceable what is still missing.
• Read in the right order. First the contract notice for the key parameters, then the application conditions (the rules), then the contract terms (risks: liability, penalties, payment) and finally the specification for pricing.
• Assess contract risks early. Review penalties, liability rules and warranty periods before pricing – they belong in the calculation and in the go/no-go decision, not only after the award.
• Use bidder questions strategically. Clarify ambiguities 7–10 days before the deadline via a bidder question and read the other bidders' answers too – they are often just as revealing as your own.
• Automate document analysis. For extensive procedures, automatic extraction of deadlines, mandatory evidence and key clauses from the tender documents pays off. Patterno finds matching tenders early and pulls the key parameters into the dashboard in structured form – more lead time for a thorough review of the documents.
