Engineers price guides with example budgets
Price guides for engineering services, structural calculations, and project oversight.
Prices and Budgets for a Structural Calculation Project
The average cost of a structural calculation project is around 1.20 €/m². This price, however, can vary. Rates are adjusted for larger or particularly simple projects. However, they can increase if the geometry is complex.
Budgets and Rates for a Building Systems Engineer
A basic installations project for a residential property can cost on average around 1,000 € - 1,200 €. The price can be modified depending on the installations included and also if technical on-site assistance or certified projects are needed. The complexity of the work can also significantly increase the budget.
All prices shown are indicative ranges based on verified quotes. Detailed ranges become more complete as guides are normalized and published.
