A basis from social housing
The technical framework most used in Flanders was developed by the regional social housing body, as a basis for the particular specifications of its own projects. Its use today reaches beyond its sector of origin.
Two characteristics follow.
Its original purpose is sectoral. It was designed for one specific type of programme, which explains some of its orientations, whereas the CCTB aimed from the outset at a general framework.
Its use has outgrown that frame. It is today regarded as the most up-to-date generally available neutral base text in Flanders, widely adopted outside social housing, and integrated by default into several professional tools.
It succeeds an older framework, of which it is a fully reworked and updated version. Continuity of numbering between the two is not guaranteed.
The fundamental difference: it is not a citation document
This is the point that structurally separates the two regions, and it is explicitly acknowledged by the body publishing the Flemish framework. The Flemish framework works by integrated text rather than by citation.
Under the CCTB, the particular specification cites. It names the framework and states only the clarifications, additions and derogations specific to the contract. The technical content remains in the framework.
Under the Flemish framework, the particular specification transcribes. When preparing a particular specification, one starts from the most recent version of the framework and all articles relevant to the project are transcribed in full into the document, which becomes self-contained.
This is not a matter of presentation but a transfer of responsibility. Under citation, updating the technical content is carried by the publisher of the framework. Under transcription, it is carried by the author of the particular specification, for their document, permanently.
What full transcription changes in practice
Four consequences for the author.
The document is longer. A self-contained particular specification holds all the articles retained, which lengthens it considerably against an equivalent citation document.
The text is frozen at the date of transcription. A later evolution of the framework does not propagate to the document already drafted. The particular specification ages with the project.
Responsibility for the content passes to the user. The publishing body expressly disclaims liability for any erroneous technical provisions, transcription of the texts taking place entirely under the responsibility of whoever transcribes them.
Choices must be settled within the text. The framework contains options left open, marked as such, which the author must resolve on transcription. A text transcribed without resolution leaves ambiguities in a contract document.
| Criterion | Walloon framework | Flemish framework |
|---|---|---|
| Mechanism | Citation document, referenced by index | Text integrated into the document |
| Size of the specification | Small, limited to indexes and additions | Large, full text reproduced |
| Update | Annual, cited by version | Tracked by the document's author |
| Main risk | Wrong version cited | Invisibly superseded text |
| Check to perform | Verify the applicable version | Compare reproduced text with the framework |
Where the risks sit
Three risks are specific to this method, with no equivalent under a citation document. All three stem from the presence of the full text within the document.
The invisibly obsolete text. A particular specification based on an old version of the framework does not announce it. Nothing in the document indicates that the transcribed prescription has since been amended.
Internal inconsistency. A long document assembled from articles may contain provisions that contradict one another, particularly where it was built by partial transcription from an earlier model.
Divergence from the bill of quantities. As under any framework, the bill must correspond to the prescriptions. Full transcription multiplies the volume of text to check, and therefore the checking effort. This point is covered in the article on matching specification and measurement.
What this means for a quantity surveyor
Four rules, for anyone receiving or preparing a Flemish document. They concern the version, the text reproduced and departures from the framework.
Check the version of the framework used. It is not always stated, and its absence is itself information.
Do not assume a transcribed article is current. The date of the document says nothing about the date of the text transcribed.
Spot the unresolved options. They are often marked by particular formatting in the source framework, but may survive transcription unresolved.
Do not transpose Walloon reasoning. Under the CCTB the question is "which version applies". Under the Flemish framework it is "is this text current and complete". These are not the same checks.
The method for reconciling the two logics is covered in the article on comparing a Walloon and a Flemish bill. The comparison is made there item by item.
This article reflects the position of professional frameworks at the date of checking and serves as orientation. It does not constitute legal advice and does not replace consulting the official source.
