BIM adoption has transformed how project teams design, coordinate and document buildings. In 2026, 68% of AEC professionals have already integrated BIM into their design processes — and the trend is accelerating. But in many projects, the raised access floor remains one of the last systems to be properly integrated into the model — if it is integrated at all.

The result is always the same: coordination conflicts at advanced stages, plenum height decisions made with incomplete information and finish specifications that don’t align with the rest of the model.

Why the raised access floor needs to enter the model from the start

The raised access floor is not a finishing element added at the end of the BIM model. It is a system that conditions the coordination of all underfloor installations — electricity, data, HVAC, plumbing — and determines the usable clear height of every space in the building.

Introducing the raised access floor system into the BIM model from the schematic design stage allows:

• Detection of MEP coordination conflicts before they reach the construction site — avoiding costly changes at advanced project stages.
• Definition of the correct plenum height for each zone of the building based on the actual installations it needs to accommodate — not generic estimates.
• Coordination of accessory positions — diffusers, electrical boxes, access hatches — with the space layout from the very first sketch.
• Generation of precise technical documentation for the tender and construction process — reducing ambiguous interpretations that generate site changes.

GAMAFLOR in BIM: objects and technical documentation

Polygroup provides project teams with the technical documentation needed to integrate GAMAFLOR systems into BIM models — including CAD/BIM files available for direct download from the website for PAC, BANK and Full Steel systems.

This documentation allows architects and engineers to work with real system geometry and data — not generic approximations — from the design stage through to construction documentation.

BIM as a specification tool, not just a documentation tool

The value of BIM for raised access floor specification goes beyond graphic documentation. A correctly configured model allows simulation of system behaviour in the real project context — detecting height incompatibilities, installation conflicts and coordination problems that in a traditional design process only appear on site.

At Polygroup, we support architects and engineers in integrating the raised access floor system into the BIM process from the earliest stages of each project — providing the technical documentation, BIM objects and specification support needed to make the raised access floor part of the model from day one.
