Infraestructures.cat
Adopted it as its own system in 2017, acts as its operator and acknowledges on its website that the classification is the work of the user groups.
Infraestructures.cat ↗GuBIMclass
The BIM classification system we created
A common language for classifying the information in a BIM project, created by GUBIMCat in 2017 and now managed by the Comissió BIM de Catalunya (CoBIMCat). The files to download are on the BIM Repository page; here we explain what it is, where it comes from and who contributed to it.
What it is and its principles
A common criterion for classifying BIM elements
GuBIMclass is a classification system for buildings: facilities, infrastructure and building services. Extending its scope to civil works and transport is precisely the aim of the review CoBIMCat is now carrying out.
It rests on three criteria: function, consistency and a common language. Leading international classification systems were analysed to define it: Omniclass, Uniformat, Masterformat, Uniclass 2015 and SfB.
History and governance
From volunteer project to institutional management
A full cycle: volunteer creation, building on the Infraestructures.cat base up to 2016; publication of version 1 in 2017; maturing use over the following years; and transfer of management to CoBIMCat, with the original authors' consent, following the agreement presented on 3 November 2025, so that its scope and depth can be reviewed beyond what a volunteer group can take on.

Where GuBIMclass is used
In Catalonia and the rest of Spain
Basque Government
The Libro BIM de Vivienda Pública of the Dirección General de Vivienda includes the GuBIMclass v1.2 table among the supporting documents that help bidders meet the BIM requirements.
Revit template annex ↗buildingSMART Spain
Its guide «Clasificación en los Modelos BIM» lists it among the four reference systems in Spain, and its information delivery manual uses it as the coding example.
Delivery manual ↗University teaching
The Máster Universitario en Metodología BIM at the University of Extremadura teaches it (2025-26 academic year) alongside Omniclass, Uniclass and UniFormat.
Course syllabus ↗Outside Spain
Outside Spain we have not found any public authority that requires it. What is documented is its use in research and as a reference for building national systems.
Brazil
Two papers by engineers from Palmas (Tocantins) use GuBIMclass v1.2 as the basis for their clash detection matrix, since Brazil has none of its own (CONTECC 2022; Revista Ingeniería de Construcción, PUC Chile, 2023).
Journal article ↗Colombia
The ColombiaClass proposal, presented at ISARC 2022 in Bogotá, compares its scope with GuBIMclass and cites it as an example of a system adapted to its country's language and building practice.
ISARC paper ↗Chile
The consultancy BuildBIM includes it in its comparison table of classification systems (2020), alongside Omniclass, Uniclass and Uniformat.
Comparison table ↗Co-authorship
The volunteer work of 21 people
GuBIMclass was born of the volunteer work of these original co-authors. This recognition is independent of who sits on the Coordinating Board today: it acknowledges a past fact, not a current position.
