Due to the complaints of the two non chosen bidders at the Slovenian highway company DARS d.d. the planned construction of the second tube in the tunnel will be delayed for some months. According to the original plan the first works in the tunnel should start within this month. In July 2018 the order for construction was given to the Turkish building group Cegniz Insaat, which was with its offer of 89,3 million Euros the cheapest among nine applicants.
Against this decision two companies made complaints, namely the Slovenian company Kolektor CPG and the Bosnian company Euro Asfalt.
The Austrian federal agency for motorways Asfinag chose among seven bidders the companies ARGE Swietelsky Tunnelbau GmbH & Co KG and Swietelsky Baugesellschaft m.b.H. with the most competitive offer in the value of 89,8 million Euros for the construction of 4,4 kilometers long Austrian part of the tunnel. In total the tunnel‘s length is 7,9 kilometers. The planned second tube of the tunnel is supposed to be finished in five years after the start of the works and should ensure a higher traffic safety, less traffic jams and a higher driving speed.
