You can use the 'Search' function to display all prequalified companys of the official list of approved economic operators PQ-VOB. Using the individual search parameters, you can set both the individual service areas of the prequalified companies and the way the results are displayed. Special attention should be paid to the sorting of the results. There is the possibility of random display (without sorting) as well as various sorting options (alphabetical, descending/ascending, etc.).
