K3 calculation under ÖNORM B 2061, connected to offer and post-calculation

Construction Calculation Software

A calculation that disappears into a drawer after the offer helps nobody. Construction calculation software should compute and stay connected to offer, project, and post-calculation. Anexum delivers this with DoliConstruct, a construction ERP on Dolibarr: K3 under ÖNORM B 2061, without per-seat license costs.

What is Construction Calculation Software?

Construction calculation software determines the prices of a construction service from wages, material, equipment, and overhead, and forms unit and offer prices from them. Anexum's DoliConstruct calculates price determination under ÖNORM B 2061 (the K3 sheet) and keeps the calculation connected to the bill of quantities under ÖNORM A 2063, the offer, the project, and post-calculation in one data flow. The basis is the open-source Dolibarr, so there are no per-seat license costs and your data stays in your hands. This turns the calculation from a one-off offer step into a continuous basis all the way to billing.

Service scope

  • K3 calculation under ÖNORM B 2061 (wages, material, equipment, overhead)

Common questions

What is construction calculation software?
Construction calculation software determines the prices of a construction service from wages, material, equipment, and overhead, and forms unit and offer prices from them. Good calculation software stays connected to offer, project, and post-calculation, instead of ending as an isolated spreadsheet. DoliConstruct implements this on Anexum's construction ERP.
Does DoliConstruct calculate under ÖNORM B 2061?
Yes. Price determination follows ÖNORM B 2061 with the K3 sheet, and the bill of quantities works under ÖNORM A 2063. Both standards are anchored in the data flow, so the calculation forms the basis for offer, award, and billing.
Is the calculation connected to offer and post-calculation?
Yes. Calculation, bill of quantities, offer, project, and post-calculation share one data set. Material consumption is tracked per bill-of-quantities position, and post-calculation can be set against the original. This keeps it visible where a project deviates from the plan.
What does construction calculation software cost at Anexum?
DoliConstruct builds on the open-source Dolibarr, so there are no per-seat license costs. With Anexum you pay for EU hosting, rollout, and customization. Total cost depends on scope and the number of users, and is scoped in advance.
How does DoliConstruct differ from proprietary construction software?
Established Austrian construction software is comprehensive but proprietary and tied to per-seat license costs. DoliConstruct offers the core functions for SME construction companies on an open-source basis: no per-seat license costs, full data sovereignty, and extensibility through the custom directory.
Which businesses is DoliConstruct for?
DoliConstruct targets small and medium construction and finishing businesses in Austria that want to merge calculation, offer, time tracking, and material from separate systems into one data flow, without investing in an expensive proprietary suite.
