About this asset

This Revit family provides a square void form used for creating waffle slab profiles in structural floor systems. The component is a square-shaped void former designed to create the recessed voids necessary for a ribbed waffle slab construction. It features a tapered profile with rounded corners and a flanged base, which allows for clean extraction from poured concrete. This geometric form is essential for reducing the overall dead load of deep slabs while maintaining structural rigidity through the resulting grid of concrete ribs. Its simple, clean geometry ensures it integrates seamlessly into complex structural models, providing accurate volume calculations for material take-offs and structural analysis within the BIM environment.

The download is a 502 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

In Revit, load this family into your project as a generic model or structural component. It is typically used in conjunction with in-place massing or floor slab families to cut the necessary voids. Ensure the family is hosted correctly to the structural level, and use the 'Join Geometry' tool to subtract the void volume from your primary slab. Adjust parameters as needed to align the grid spacing with your structural column layout and beam spans.

This void former is intended for use in the design of large-span structural floor systems, often found in commercial, industrial, or high-end residential projects where deep slab sections are required. It is particularly useful for engineers and architects working on complex structural floor plans that require precise void placement for material reduction and service integration. Use this in early-stage structural planning or detailed BIM coordination to ensure the waffle grid layout matches the intended structural performance and MEP routing requirements.
