Get your SketchUp model ready for quantities and cost
Pick a type and a material for each group — the extension writes the IFC class and a name Constructio understands. It lists what cannot be measured yet, shows the quantities as you model, and exports the IFC file you upload to your project.

A model that looks right is not always measurable
Groups without a type
An unclassified group is invisible to a quantity take-off: the stair treads you drew are simply not counted.
Open solids
If a group is not a closed solid, its volume cannot be measured — concrete and blocks come out wrong.
Names nobody can read
“Group 2231” says nothing; “AAC block 20 exterior wall” tells the site the material, the thickness and that it is external.
Everything the take-off needs, inside SketchUp
Types, materials and names
Wall, slab, column, beam, lintel, stair, window, door, room, roof, storey, building and more. Choose the material, exterior or interior, the concrete class or the room finish; the name is written with the measured thickness, in the panel's language.
Outliner-style check list
The whole model as a tree: open a storey and see its walls. Each line shows whether the part is classified, a part of a window, a container group, unclassified or open; closed groups show how many problems they hold.
Show = isolate
“Show” enters the group and hides the rest of the model, so you see exactly the part you are fixing. Press Esc and everything comes back as it was.
Quick take-off while you model
Length, height, one face area, volume and block count for the selected part; walls, concrete, windows, doors and rooms for the whole model. It refreshes by itself when the model changes.
SketchUp's own materials
The chosen material is assigned to the group from SketchUp's material library — aerated concrete, brick, concrete, glass, parquet. If the library does not have it, a coloured material is created.
Colour tags by type
Every type gets its own coloured tag in a “Constructio” folder. Turn on “Color by tag” and walls, slabs, windows and doors stand out at a glance.
IFC export to your project
One button exports the IFC file. Upload it on your project's “Quantities from IFC” page and get the quantities, the cost and the 3D model with floor plans.
Local and undoable
The extension runs on your computer; it needs no account and sends nothing anywhere. Every “Apply” is a single step you can undo.
Three languages
English, Turkish and Estonian — chosen automatically from SketchUp or your system, or picked in the panel. Names are written in the chosen language and the site reads all three.
From SketchUp to the cost in four steps
Install
Download the .rbz file and install it from Extensions → Extension Manager. The orange “C” appears on the toolbar.
Define
Select a group, choose its type and material, press Apply. Several groups at once are named one by one with their own thickness.
Check
Open the check list, filter to problems, press “Show” and fix each one. The take-off updates as you go.
Send
Export IFC and upload it in your project under Cost → Quantities from IFC. Enter prices and carry the quantities to the work plan.
