Our mission at Qonic is to enable users to increase the level of development of a design faster and more consistently – taking the model LOD from a design intent model to a construction model.
In our previous posts, we highlighted the possibility to enrich imported IFC files. For example, in many design intent IFC models, classification information (like OmniClass, Uniclass, MasterFormat, or DIN277) might be wrong, inconsistent, or just missing. This makes the model unfit for the purpose of quantity take-off later. Qonic can be used to fix this missing classification information, or add/modify missing attributes.
Moreover, our solid modelling toolbox enables you to fully model designs to the highest detail, including real-life building systems (wall assemblies, manufacturable products, finish layers, etc.) and connections (details, sills, insulation stones, roof caps, etc.). For example, it will be possible to split generic building elements into material layer parts. The result are separate parts, kept together as an assembly, that can be classified, filtered, and manipulated individually – giving you more control over accurate model quantities.
At the end of this Qonic workflow, the IFC model will contain the level of development needed to support full detailing and accurate model quantities during tendering and construction.
Accurate quantity measurement
In Qonic it is possible to measure the elements that you need - quickly and accurately. This can be done according to industry standard structures (NRM2, VMSW, NLSfB, and others), or by building your own. The quantities are calculated based on the geometric characteristics of an object (rather than approximated based on properties or formulas):
- Lengths of beams and columns, walls, HVAC ducts and pipes, skirting, roof caps, etc.
- Areas of flooring, plaster finishes, painting, drywall systems, etc.
- Volumes of concrete, masonry, spaces and zones, etc.
- Count of windows and doors, furnishing elements, outlets, fixtures, etc.
To correctly measure the elements, we have defined several calculator algorithms, including gross and net quantities for volumes and areas, different ways to calculate the length (according to axis, or inner/outer dimensions), and even the possibility to ignore openings that are smaller than a given size.
For every element, it is possible to calculate multiple quantities. A typical example are concrete columns, where the volume of the concrete is measured, a part of the external surface area is measured for the formwork, and another part of the external surface area is measured for certain concrete treatments, and other activities.
In the video below, we measure the net volume of the concrete panel system, which is the gross volume of the wall minus the volume of the openings. Also, we measure the axis length of some beams in the model, and we measure the net area of the gypsum ceiling panels in the building.
In the next video below, we calculate the net area of a floor slab, so excluding openings in the slab, except when the opening is smaller than, for example, 0.5m2. This is a common calculation rule in many measurement standards, because smaller openings, penetrations, and rebates are often measured as separate activities.
Moreover, quantities can be easily verified in a visual way to make sure the calculated results are transparent and can be trusted. The results and schedules can then be shared with colleagues and third parties online, and reports can be exported to prepare bill of quantities, cost estimates, or cost plans.
