# Italy's BIM mandate in 2025: 4,963 public works contracts above €2 million > We analysed ANAC open data for 2025: 4,963 public works lots fall within Italy's BIM mandate, 7% more than in 2024. Where they are and who tenders them. Published 2026-11-06 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.

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.
