Creating a Bill of Quantities: Structure, Sample, Rules and GAEB File
How a BoQ is structured, which item types exist, what VOB/A and the Austrian BVergG require, and how plans and a building description become a GAEB file.
Insights, news and knowledge about AI in construction.

How a BoQ is structured, which item types exist, what VOB/A and the Austrian BVergG require, and how plans and a building description become a GAEB file.

How a bid tabulation is structured, what it reveals, which rules apply when evaluating bids and how the AI agent builds it from PDF and Excel bids.

Take walls by material off the PDF floor plan, count doors and windows and take the quantities over as an Excel list. Plus the measurement rules for masonry and concrete in brief.

Take façade areas off the elevations by build-up and finish, handle openings correctly and take the quantities over as an Excel list. Plus the rules for ETICS, render and ventilated façades.

Take paved areas, gutters, sewers, manholes and trees off the site plan, keep new work apart from existing features and take the quantities over as an Excel list.

Calculate wall, ceiling, façade and plaster areas from the PDF drawing, marked on the plan and delivered as an Excel takeoff, with the rules of DIN 18363.

Detect drywall partitions on the floor plan, calculate wall areas for one side or both and check them against the rules of DIN 18340.

Calculate room areas automatically, take the floor build-up into account layer by layer and export the quantities to Excel.

Electrical and HVAC: count fixtures and fittings on the MEP plan, measure pipes, ducts and cable routes and take the quantities over as an Excel list.

Risk analysis, selection and award criteria, deadlines and pre-qualification: how an AI agent reviews tender documents – for contractors and designers in Austria, Germany and Switzerland.

Every project generates thousands of documents. Almost none of that knowledge survives to the next bid.

Most "AI agents" in construction are just chatbots. The real unlock isn't a better model — it's a better environment where agents and your most experienced people work side by side.
