The construction of the extension of the Sofia metro was performed without a prepared or approved project, rails were laid without project, a non-certified concrete was used and a number of financial irregularities were also committed.

In addition, the municipal company Metropolitan which is a beneficiary of EU funding under the Operational Programme Transport (OPT) tried to add in the project costs for VAT amounting over BGN 2.6 million, which is unacceptable.

As a result, the contractors of the two intercepts of the way from Nadezhda quarter to Cherni Vrah Blvd (Lozenets quarter) - Metro Trace Group and the Turkish Doush Insaat Ve Ticaret will not receive nearly BGN 3 million from OPT.
