Spain's BIM mandate is now in force: what the 2026 thresholds mean for your project

Spain crossed a line this year that the whole construction sector saw coming for a decade: BIM is no longer optional in public procurement. The state Plan BIM, managed by the Interministerial BIM Commission (CIBIM), has been rolling out since April, and since January 1, 2026 the thresholds got serious.

The thresholds, in plain terms

• Contracts from €2M to €5.4M — require Initial BIM Level: a coordinated 3D model with structured information delivery.
• Contracts of €5.4M and above — require Medium BIM Level: deeper data integration including quantities and budgets (5D) and centralized information management.

Every ministry-dependent contracting body must now write these requirements into their tender documents. Regional and local administrations are following the same path.

Why this matters for renovation work

Most public building work in Spain touches something that already exists — schools, hospitals, stations, heritage. You cannot deliver a compliant BIM process on top of record drawings that describe what someone intended to build decades ago. Tenders increasingly demand a verifiable existing-conditions model: geometry captured on site, with documented accuracy, delivered in open formats.

That is exactly what Scan to BIM produces: laser capture with the Leica RTC360 (±2 mm point accuracy class), converted into Revit models at the LOD the tender requires, delivered as RVT + IFC + point cloud with a QA trail any reviewer can audit.

How bidders are adapting

• General contractors are locking in reality-capture partners before bidding, so the existing-conditions model is priced and scheduled from day one.
• Engineering firms are attaching point clouds to their deliverables to make coordination against existing MEP verifiable.
• Public owners are commissioning as-built models of their building stock ahead of tenders, so every bidder prices the same reality.

Don't confuse levels with LOD

The Plan BIM levels (Initial, Medium, Advanced) describe the process maturity of the contract. The LOD of your model (200/300/400) describes element reliability. A compliant bid usually needs both specified — our guide to LOD 200 vs 300 vs 400 explains how to write that line in a tender response.

The takeaway

If you bid Spanish public work in 2026, existing-conditions capture is no longer a nice-to-have — it is tender compliance. Getting it survey-grade, documented and in open formats is the cheapest insurance a bid can buy. Talk to us if you want a compliant capture plan for your next tender.
