Ambrus + Co

For many years we have been working exclusively and successfully with the data STLB-Bau and DBD-BauPreise in connection with the Bachmann AVA in the AVA area. The application is effective and makes a large contribution to the cost security of our construction projects. This is reflected in the satisfaction of our clients and contributes to the success of our services and our office. Competent support from the DBD Center is an integral part of our success-oriented cooperation.

DBD-KostenKalkül is an excellent tool for calculating the costs of new construction projects. Through the library of components, service items and costs operating in the background, we arrive at detailed, project-specific results quickly and clearly. Through the DBD Center, we have received individual support and comprehensive advice.

The data transfer from the CAD via IFC into cost calculation and then the export together with the price into my AVA program works well. An almost usable "LV" can be displayed, but it has to be checked again to be on the safe side and adapted/supplemented here and there.

All in all an enormous time and personnel saving. I am very satisfied with this solution.

We use STLB-Bau for the legally compliant description of subcontractor services according to the latest standards. It serves above all as a supplement to our own tender database. Because, let's be honest, which of us can be up to date in all building construction trades and describe them in a legally impeccable manner?

The standard service book is our proven instrument.

Plan A

For me, cost calculation is an instrument for internal quality assurance throughout the entire planning process.

In my office we use the cost calculation program from the first cost estimate. Its simple handling makes it possible to make very detailed statements about construction costs at a very early stage. Any potential savings can be easily explored by exchanging the components. But its great benefit lies particularly in the fact that this data can be easily updated over the subsequent work phases. If one also uses the cost elements and the STLB construction in this context, it is a small step with the corresponding AVA software to generate specifications from the cost calculation. By the possibility to generate own elements, this software offers a large flexibility. It can also be used in very special areas. I find the self-control particularly comfortable due to the integrated cost elements. This makes it almost impossible to forget special components, for example in connection details, when tendering and calculating costs, even under time pressure. A tool that offers you really continuous security in the planning process. The software is perfectly supported by the services of the DBD Center, which always helps you in a friendly way should any questions arise.
