In 2025 Italy published 4,963 public works lots above €2 million, the threshold above which article 43 of Legislative Decree 36/2023 makes digital information management (BIM) mandatory. That is 7.1% more than in 2024, worth €53.1 billion, about 70% of the value of all works put out to tender.
We processed ANAC's open data on every works CIG (lot code) of 2024 and 2025 to see how many tenders the mandate really affects, where they are and who issues them. This is the first edition of the BIMON BIM Tender Observatory, and we will update it every year with the same method.
The numbers at a glance
| 2024 | 2025 | |
|---|---|---|
| Works lots published | 141,044 | 163,699 |
| Lots above €2 million | 4,632 | 4,963 |
| Value of lots above €2 million | €74.7bn | €53.1bn |
| Share of total works value | 80% | 70% |
| Lots between €2 million and the EU threshold | 2,912 | 3,449 |
| Lots above the EU threshold | 1,720 | 1,514 |
| Contracting authorities with at least one lot | 1,253 | 1,213 |
Few lots, most of the value. Lots above €2 million are only 3% of works lots, yet they hold 70% of the value.
The €2–5.5 million band is growing. This is where the mandate is newest, and in 2025 it rose 18.4%, from 2,912 to 3,449 lots. Many medium and small authorities tender here, often for the first time with BIM requirements.
The largest lots are fewer. Above the EU threshold lots fell from 1,720 to 1,514 (−12%). Part of the drop relates to recovery-plan tenders: lots above €2 million flagged as PNRR or PNC went from 858 to 682.
Where they are
| Region | Lots 2025 | Lots 2024 |
|---|---|---|
| Lazio | 695 | 658 |
| Lombardy | 573 | 498 |
| Campania | 374 | 368 |
| Marche | 361 | 251 |
| Sicily | 353 | 275 |
| Emilia-Romagna | 344 | 339 |
| Veneto | 332 | 360 |
| Tuscany | 287 | 244 |
| Piedmont | 273 | 333 |
| Apulia | 213 | 254 |
The strongest growth is in Marche (+44%, with much of the 2016 earthquake reconstruction) and in Trentino-Alto Adige, which went from 90 to 183 lots.
What kind of works
| Category (main CPV code) | Lots 2025 | Share |
|---|---|---|
| Roads, railways and networks | 1,844 | 37.1% |
| Buildings | 776 | 15.6% |
| Completion and renovation | 656 | 13.2% |
| Building services (MEP) | 330 | 6.6% |
| Hydraulic and maritime works | 282 | 5.7% |
| Bridges, tunnels and civil works | 220 | 4.4% |
| Other categories | 855 | 17.2% |
Buildings, renovation, building services and specialist building works together add up to 1,960 lots, 39.5% of the total. This is where BIM MEP design and clash coordination make the biggest difference on site.
Who tenders them
| Contracting authority (classified from its name) | Lots 2025 | Share |
|---|---|---|
| Networks, transport and utilities | 1,472 | 29.7% |
| Other companies and bodies | 1,004 | 20.2% |
| Municipalities and unions of municipalities | 832 | 16.8% |
| Regions and regional bodies | 496 | 10.0% |
| State, ministries and commissioners | 249 | 5.0% |
| Provinces and metropolitan cities | 239 | 4.8% |
| Healthcare | 133 | 2.7% |
| Universities and research | 99 | 2.0% |
| Others | 439 | 8.8% |
832 lots above the threshold come from municipalities, and 1,213 different authorities published at least one. For many of them a BIM tender is not yet routine.
What it means for authorities and contractors
Contracting authorities need a training plan, an organisational act, a common data environment (ACDat) and the digital process and data environment managers before their first tender above the threshold. Not every lot above €2 million is in scope: about one in four (1,317 in 2025) mentions maintenance in its subject, and ordinary and extraordinary maintenance is excluded unless the asset is already managed in BIM. To check a specific tender, use the BIM Mandate Checker.
Contractors and designers face almost 5,000 lots a year, 414 a month on average, that require an information management offer, verifiable models and a working common data environment. If you need a team to set this up with you, see our BIM management service.
Method and limits
- Source: ANAC, National Public Contracts Database (BDNCP), monthly CIG datasets from January 2024 to December 2025, licence CC BY-SA 4.0. BIMON's processed data is released under the same licence.
- Unit: the CIG (single lot) with "works" as main object, deduplicated, cancelled CIGs excluded.
- Scope: lot value above €2 million, the threshold of article 43 of Legislative Decree 36/2023 as amended by Legislative Decree 209/2024, in force since 1 January 2025. The law refers to the estimated cost of the whole intervention, which can span several lots.
- What we cannot measure: ANAC does not record whether a tender requires BIM. Maintenance and the higher threshold for listed heritage buildings cannot be applied reliably, and the transitional rules of article 225-bis exclude some procedures started by 2024.
- 2024 comparison: the general mandate was not yet in force in 2024; the comparison uses the same scope to measure tender volume.
- Classifications: region from the ISTAT code of the works location, category from the main CPV code, authority type from keywords in its name.
