Solibri ✓

Solibri is BIM quality-assurance software, now part of Nemetschek Group, built specifically to check IFC models against custom rules for clashes, standards compliance and data completeness -- rather than an authoring tool for creating a building model, Solibri's entire purpose is validating a model someone else has already built, making it a QA/QC layer that sits downstream of Revit, Archicad, or any other IFC-exporting BIM authoring platform.

IFC model visual inspection is the foundation everything else builds on: Solibri opens and renders IFC files with a level of native fidelity that general-purpose BIM viewers often don't match, reflecting the company's long-standing specialization in openBIM data validation rather than general 3D visualization. Automated clash detection runs on top of that, identifying geometric conflicts between disciplines (say, a structural beam intersecting a duct run) before they become an expensive field problem.

What sets Solibri apart from a basic clash-detection tool is custom rule-based model checking: firms can define their own rulesets -- covering anything from fire-egress distances to accessibility clearances to a client's specific BIM execution plan requirements -- and Solibri checks every model that comes through against those rules automatically, rather than relying on a human reviewer to manually catch every standard violation. That rule-based checking is Solibri's core differentiator versus more general-purpose model-review tools.

BCF issue management lets Solibri-flagged problems get exported as standardized BCF (BIM Collaboration Format) issues that other BIM tools and platforms can import directly, so a clash or rule violation Solibri catches becomes an assignable, trackable task in whatever project-management or CDE system a firm already uses, rather than a dead-end report nobody actively works from. Point cloud checking, available on the Advanced tier, extends the same rule-based validation logic to comparing a model against as-built laser-scan data.

Pricing runs from €1,428/year (Essential) to €2,109/year (Advanced), placing Solibri in the mid price band of this catalog -- a real cost, but one that's typically justified by the expensive field rework a well-run model-checking process prevents on larger, multi-consultant projects. Named customers on Solibri's own site include Copenhagen Airport, Remmers Bouwgroep, Hercuton and McLaren Construction, spanning major infrastructure, construction, and manufacturing organizations across Northern Europe and the UK.

Solibri's role in a typical project workflow is worth spelling out concretely: an architect or engineer models in Revit or Archicad, exports an IFC file at defined project milestones, and a BIM manager or QA specialist runs that IFC through Solibri against the project's established ruleset before it's shared with the wider team or submitted to the client. That checkpoint-based workflow is why Solibri tends to be owned by a dedicated BIM management or QA role within a firm, rather than something every modeler interacts with directly day to day.

As part of the Nemetschek Group alongside Archicad/Graphisoft, Vectorworks, Allplan and Bluebeam, Solibri occupies a distinct role in that portfolio: rather than competing for authoring market share against Revit, it's Nemetschek's answer to the openBIM quality-assurance layer that sits above whichever authoring tool a project team actually uses -- notably, Solibri checks IFC models regardless of which platform produced them, so it remains useful even on projects where the primary authoring tool is Revit rather than a Nemetschek product.

Editor’s takeBIM•STACK editor's take: Solibri earns a genuinely specific and valuable niche as the model-QA layer most BIM workflows are missing -- it's not competing with Revit or Archicad so much as sitting downstream of them, catching the standards violations and clashes that a purely visual review would miss. The honest caveat is that several collaboration and cloud-related fields are marked unconfirmed in this catalog's own feature data, so firms should verify Solibri's exact cloud/team-workflow capabilities directly rather than assuming parity with dedicated CDE platforms like Trimble Connect or Catenda Hub.

Solibri's learning curve centers less on basic navigation -- opening and visually inspecting an IFC model is fairly approachable -- and more on building an effective custom ruleset. Getting real value from Solibri means translating a firm's actual standards, a client's BIM execution plan, and relevant code requirements (egress, accessibility, clearances) into Solibri's rule-authoring system, which is a genuine skill that takes real investment to develop well, similar to how getting value out of Plannerly's BEP tooling requires upfront standards work.

Once a firm has built out a solid library of reusable rulesets, ongoing use becomes considerably more routine -- checking each new model submission against an established ruleset is a fast, repeatable process. That front-loaded investment pattern (steep initial ruleset-building effort, fast ongoing use) is common across rule-based QA tools generally, and Solibri is no exception.
