A bill of quantities from IFC that holds up on every project

A one-off IFC export is not a complete, repeatable list built to your rules. Koto reads the model and builds the same bill of quantities, in your own column format, every project and every revision.

Every takeoff starts from zero

A bill of quantities from IFC is a quantity list derived directly from the BIM model, instead of from a manual takeoff. Each line refers to elements that actually exist in the model. Right now, your bill of quantities depends on who built it. One estimator counts differently from the next. A one-off export catches what is in the model, not what your rules say should be on the list. A missing item does not stay small: it becomes a back-order, and a back-order can stop a site. One incident like that easily costs €2,000 to €5,000. Construction failure costs run 5 to 15% of revenue, while margins run 2 to 3%. Work out how many missing lines that leaves room for.

A one-off export lists what is in the model, not what your ordering rules require.
Every estimator applies their own logic, so no two takeoffs match.
A forgotten item only surfaces on site, as a back-order and a stalled crew.

Bill of quantities: manual versus with Koto

Every bill of quantities starts from zero in ExcelThe pipeline fills the bill of quantities automatically from the model

One estimator counts and measures differently from the nextThe same rules apply to every bill of quantities, whoever opens it

A revision means starting the bill of quantities overThe list follows the model automatically on every revision

The column format depends on who formats the sheetYour own column format is built into the pipeline

How it works

Configure the rules once

Set up which elements, properties and categories belong on your bill of quantities, and in which column format you need them. This happens once per company.

Koto reads your model

IFC, the open EN ISO standard, or Vertex BD native. Revit models come in through IFC. No re-export, no manual reformatting.

The BOQ builds itself

Koto applies your configured rules to the model and generates a complete bill of quantities, in your own column format, ready for ordering or your ERP.

It repeats on every project

Configure once, then it runs automatically on every project. A new model or a revision produces the same list, built the same way, without redoing the setup.

See it on your own model

Koto runs live at construction companies today. In a demo we take your own model, run it through a pipeline and you watch your own bill of quantities come out. Real output, not slides.

Works with what you already have

Koto reads the model you already build. No new CAD, no new ERP, no lock-in.

Output in your own column formats. Your data stays yours: switch CAD or ERP, and your Koto pipelines keep working.

Questions about BOQ from IFC

Yes. The output format is part of the configuration: your column names, your units, your grouping. Export as Excel or CSV, or send it straight into Odoo.

Koto works with what the model contains. Missing or incomplete properties show up as gaps you can see and fix at the source, instead of silent errors further down the line.

A revision does not mean starting over. The same configured rules run against the new model, and the bill of quantities updates without extra setup.

You configure the rules once per company: which elements, which properties, which column format. After that, every project and every revision runs automatically.

Koto extracts the quantities that are in the model, and adds what isn't modelled through your own rules: fixings, consumables, accessories. That gives you a complete bill of quantities, in your own column format, instead of only what happens to be drawn.
