1. Principle and prerequisites

1.1. Scope

This guide aims to provide insight into transaction details for the transaction model T004 - Call for Tenders 1.2. The transaction description is meant to be a standalone description to be used as a part of one or more procurement profiles. It describes syntax mappings, requirements, rules and example.

The transactions, specified in this document are intended to be exchanged between the tendering systems of economic operators and contracting bodies. This means that it is expected that the parties have connected their systems to the internet, and that they have middleware in place to enable them to send and receive the transactions in a secure way, using an agreed syntax.

The content model of the transactions can also be used in procurement platforms or notification platforms, so that these platforms as well as procurement systems of economic operators and contracting bodies are based on the same information and process models, which makes them more interoperable. Even if platforms are not technically interoperable, the content model facilitates understanding the tendering documents and to participate in the tendering process.

1.2. Parties and roles

The following parties participate as business partners in this transaction, acting in the roles as defined below

Table 1. parties

5. PEPPOL Identifiers

PEPPOL has defined a Policy for use of Identifiers that specifies how to use identifiers in both its transport infrastructure and within the documents exchanged across that infrastructure. It also introduces principles for any identifiers used in the PEPPOL environment. The e-Tendering pilot adopts and extends the PEPPOL Policy in the following ways:

5.1. Party Identifiers used in business (UBL) documents

All party identifiers (cac:PartyIdentification/cbc:ID) have an optional scheme identifier attribute '@schemeID'. If used, the value shall be chosen from the code list ICD codes.

Examples of usage in cac:PartyIdentification
<cac:PartyIdentification>
        <cbc:ID schemeID="0088">5790000435968</cbc:ID> (1)
</cac:PartyIdentification>
1 schemeID attribute is optional, but when used, the codes must be from ICD codes

5.2. Electronic address identifier used in business (UBL) documents

All electronic address identifiers (cbc:EndpointID/@schemeID) use the Electronic Address Scheme code list (EAS), maintained by CEF (CEF Code lists).

Valid values are found here: EAS codes.

Examples of usage in cbc:EndpointID
<cbc:EndpointID schemeID="0184">DK87654321</cbc:EndpointID> (1)
1 schemeID attribute is mandatory and must use values from EAS codes

5.3. Document Identifiers used in business (UBL) documents

5.3.1. UBL Version ID

This transaction model is using the UBL 2.2 syntax. The namespace of the XML-message does only communicate the major version number. Since it is important for the receiver to also know what minor version of the syntax that is used, the element UBLVersionID must be stated with the value 2.2:

Examples of usage in PartyIdentification and EndpointID
<cbc:UBLVersionID>2.2</cbc:UBLVersionID>

5.3.2. Profile ID

ProfileID identifies what business process a given message is part of, and are connected to one business process, and may contain multiple document types.

Valid profile identifiers are described in the Syntax mapping for Call for Tenders - Syntax mapping for T004 - Call for Tenders 1.2 - and the corresponding BIS document, see Main documentation site.

5.3.3. Customization ID

The PEPPOL Customization ID identifies the specification of content and rules that apply to the transaction. Profiles are connected to one business process (ProfileID), and may contain multiple transactions. Valid document instances shall contain corresponding ProfileID and CustomizationID.

CustomizationID is a string without spaces. Which customization identification should be used, is based on which transaction is sent.
For implementers, please note that the process identifiers in the document instance MUST correspond to the SMP process identifier.

6. Description of selected parts of the transaction

In this chapter you will find descriptions and examples of parts of the documents, in addition to the description and examples given in the related CEN BII and ESPD Documentation.

6.1. Definition of the procurement project

The call for tenders in this profile is intended to provide unstructured information of the procurement project. The economic operators are expected to read the provided documents and prepare their tenders following the requirements established as unstructured information.

6.1.1. Call for tenders without lots

A Call for tenders without lots has a single cac:ProcurementProject class. The procurement project and all the details of the project are described using the documents attached or referred using the cac:AdditionalDocumentReference class.

In this case, the document instance must not contain any cac:ProcurementProjectLot class.

The example below demonstrates the use of the cac:ProcurementProject class for a tendering process without lots. The structured information does not convey economic information. It is used to describe the project, to provide classification codes using the Common Procurement Vocabulary and the location where the project will be executed using the NUTS code. The procurement project in does not describe the tender deliverables.

Procurement project
<cac:ProcurementProject>
        <cbc:Name>Laptops</cbc:Name>
        <cbc:Description>Laptops</cbc:Description>
        <cbc:ProcurementTypeCode listID="PROJECT_TYPE">2</cbc:ProcurementTypeCode>
        <cac:MainCommodityClassification>
                <cbc:ItemClassificationCode listID="CPV">98300000-6</cbc:ItemClassificationCode>
        </cac:MainCommodityClassification>
        <cac:RealizedLocation>
                <cbc:ID schemeID="NUTS">DE01</cbc:ID>
        </cac:RealizedLocation>
</cac:ProcurementProject>

6.1.2. Call for tenders with lots

When the Call for tenders has to be split into lots, the cac:ProcurementProject class must define the overall summary of the project and there must be a cac:ProcurementProjectLot class per each lot.

The cac:ProcurementProjectLot class only requires to define the lot identifier and the name of the Lot. All the details on the lot are described as unstructured documents referred from the cac:AdditionalDocumentReference class.

The details of each lot are described using unstructured documents referred into the call for tenders

Call for Tenders with lots
<cac:ProcurementProjectLot>
        <cbc:ID>1</cbc:ID>
        <cac:ProcurementProject>
                <cbc:Name>First part of the works project</cbc:Name>
        </cac:ProcurementProject>
</cac:ProcurementProjectLot>
<cac:ProcurementProjectLot>
        <cbc:ID>2</cbc:ID>
        <cac:ProcurementProject>
                <cbc:Name>Second part of the works project</cbc:Name>
        </cac:ProcurementProject>
</cac:ProcurementProjectLot>

6.2. Description of the tendering process

The call for tenders describes some information of the tendering process.

The cac:TenderingProcess class contains the deadlines of the process and the codes describing the type of procedure, the type of presentation and the type of submission.

The example below describes an open procedure and the deadlines of the process. The cbc:ProcedureCode and the tender submission end date are required data elements.

Tendering process
<cac:TenderingProcess>
        <cbc:ProcedureCode listID="PR_PROC">1</cbc:ProcedureCode>
        <cbc:SubmissionMethodCode listID="BII_SUBMISSION">ELECTRONIC</cbc:SubmissionMethodCode>
        <cac:TenderSubmissionDeadlinePeriod>
                <cbc:EndDate>2017-10-20+02:00</cbc:EndDate>
                <cbc:EndTime>13:32:11.891+02:00</cbc:EndTime>
        </cac:TenderSubmissionDeadlinePeriod>
</cac:TenderingProcess>

6.3. Description of the attachment of documents

Using this transaction, the information of the tendering process and the details of the procurement project are described in unstructured files. The call for tenders reference the unstructured files so it is possible to access them through their URI.

The cac:AdditionalDocumentReference class contains references to all the files for the tenderers to prepare their bids. The mandatory cbc:ID element contains an identifier of the file, and the cac:DocumentStatusCode is used to inform the tenderer about the action that has to be done with the current document.

Find below an example on how to define a provided document reference based on the e-SENS pilot project.

In this example, the contents of the coded elements DocumentTypeCode and DocumentStatusCode have been defined following the e-SENS project coded values.

6.4. European Single Procurement Document (ESPD)

Article 59 of the new Public Procurement Directive 2014/24/EC introduced a new concept, the European Single Procurement Document (ESPD) which is a self-declaration document intended for preliminary evidence in a public procurement procedure. The main objective of the ESPD is to reduce the administrative burden and lead to considerable simplification of participation in public procurement procedures for buyers and suppliers. ESPD will reduce the burden by removing the need to produce a substantial number of certificates and documentation related to exclusion and selection criteria.

Documentation and services related to ESPD are provided by the European Commission. This is an overview of the currently available resources:

Implementers of this profile attach ESPD Request/Response by adding a DocumentReference. The transaction T004 does not prescribe the use of a specific ESPD version. The use of specific ESPD versions by the Contracting Authority may result into incompatibilities with the systems available to the Economic Operator. Thus, it should be described by the Contracting Authority in the Tendering Documents which ESPD version is used and how it can be returned by Economic Operators. Values to indicate that an ESPD is used as part of the Call for Tenders documents are:

cac:DocumentReference/cbc:DocumentTypeCode

6.5. Transport of encryption certificate via the Call For Tenders

6.5.1. Introduction

The Call For Tenders (CfT) business document is used by the contracting authority to provide an economic operator with the latest updated procurement documents. Besides transporting procurement documents it MUST be used to transport the encryption certificate needed by the economic operator to encrypt his tender for submission.

6.5.2. Encryption certificate

The encryption certificate MUST be transported as an attachment within the Call For Tenders ASIC. The Call For Tenders business document contains metadata regarding all attachments thus also for the tender encryption certificate.

This metadata is resembled by the UBL container cac:AdditionalDocumentReference. In the case of the encryption certificate this container MUST contain the elements and values mentioned in the table below.

To identify the encryption certificate, the UBL MUST contain exactly one AdditionalDocumentReference-container as described below. Any other container MUST NOT make use of this value combination.
