Los 1: DN 100 - 250;

Lot 3: DN 100 - DN 1200 and egg profiles up to egg 1000/1500.

The aim of the award procedure is to bind a total of ten different contractors. For Lot 1 and Lots 2 and 3, uniform contract prices are formed. The selection of the companies to be invited to submit tenders for the respective lots takes place within the framework of the participation competition. In order to determine the contract prices, sample construction sites are calculated separately according to Lot 1 and Lots 2 and 3. The sample construction sites reflect typical individual orders, which in the majority of cases are the basis of the orders. The average value is calculated from the most economical unit prices determined in this way and rounded according to the mathematical rules.
