Public BIM in infrastructure: how Europe demands it, in six portals
The data from six official portals of public infrastructure clients — federal Germany, state-level Spain, the Basque Country, Norway, Sweden and the Netherlands — was collected directly from the sources and compared to understand how each turns BIM into a procurement requirement. The distance between them is not one of political will: it is one of technological generation of the requirement itself.
The map
| Jurisdiction | Client | Instrument | Volume | Machine-readable |
|---|---|---|---|---|
| Germany | BMDV (federal) | LOIN (DIN EN 17412): object × phase × level | 3,439 LOIN | Full — open JSON API |
| Spain | CIBIM (Min. of Transport) | BIM requirements in pliegos | 29 reports 2017–2025 | Partial — quarterly PDF |
| Basque Country | BIM Euskadi | Project directory | 38 projects | Full — CMS API |
| Norway | Statsbygg | Requirements tree (Kravene) | 69 chapters | High — structured HTML |
| Sweden | Trafikverket | TDOK — regulatory documents | 77 documents | Low — index + PDF |
| Netherlands | Rijkswaterstaat | Data-eisen — data requirements | 10 sets | Low — interactive app |
Three generations of requirement
- Document generation. BIM enters as text in the tender documents and is counted by hand. The Spanish case: the CIBIM Observatorio has read pliegos one by one since 2017 and publishes in PDF.
- Catalogue generation. The requirement is a standardised, versioned document, referenced in the contract. Sweden (TDOK) and the Netherlands (Data-eisen) — the contract states which sets are mandatory.
- Data generation. The requirement is a record queryable by API: the German LOIN (by object, phase, purpose and requirement level) and the Norwegian SIMBA, which stands out for machine-verifiable requirements — the model can be validated automatically against the requirement.
Spain: from 215 to 1,232 BIM tenders in seven years
Since 2018, the number of Spanish public tenders with BIM requirements has multiplied by 5.7, and the associated investment by 9.6. Plan BIM made BIM mandatory across the Administración General del Estado and the leadership changed hands: until 2022 the regional level led, since 2023 it is the state level.
In the 2nd quarter of 2025, with fifteen months of mandatory BIM in the state administration, 356 tenders and €1,544M were added. The 2024 breakdown: €2,388M state, €735M regional, €974M municipal.
Germany: the requirement sits in execution and can be validated
The federal database (BMDV BIM-Portal) defines 3,439 levels of information need — one per combination of object type, phase (LPH 1–9) and requirement level (basic, AwF 100, AwF 120). 3,388 come from the roads; the railway and the waterways have barely entered.
The most specified phases are site supervision (LPH 8, with 822 LOIN) and detailed design (LPH 5, with 708) — the profile is 4D/5D: schedules, quantities and costs, coordination of disciplines, progress and quality control. A classification trio (object type, class and object group) appears in 3,407 of the 3,439 records, accompanied by 6,865 IFC mappings: the bridge to validating models automatically.
Norway, Sweden and the Netherlands
The Statsbygg SIMBA is the most complete requirements tree outside Germany: numbered chapters, role-by-role guidance — including the bidder — and a dedicated section of machine-verifiable requirements. Sweden publishes the specification as versioned TDOK (77 documents of strategy, requirements and information management); the Netherlands organise it into ten sets of data requirements, from CAD to topography, invoked directly by the contract. The Basque Country is the only one of the six to publish what happened — a directory of 38 projects with declared results, framed by its Plan BIM 2026–2030.
What it means for an Iberian bidder
- German market: the requirement concentrates in execution and can be validated by machine — a proposal gains substance by citing the exact LOIN per object and phase, all queryable in the federal database.
- Spanish market: BIM is mandatory in the state administration; what sets one apart is mastering the vocabulary of the pliegos — BIM uses, levels of information, deliverables — exactly the indicators the Observatorio measures.
- Nordics and the Netherlands: mature and stable requirements; the way in is to meet them to the letter, without translating them into a “BIM culture” of one's own.
European backdrop: the EU BIM Task Group publishes the reference handbook for public clients in more than ten languages, including Portuguese.

All numbers were extracted directly from the official portals on 3 September 2026 (open APIs, PDF and HTML); no value is estimated by us. The Spanish report for 2019 has an internal discrepancy between the annual total and the sum per administration — we kept both readings in our data.
