From the words of İzmir mayor Tunç Soyer (he also watched tender proposal openings online broadcast), lowest bidder is not automatically lowest bidder. He said he is happy with strong technical and financial structure of bidding companies. But he said there are bid differences between bids. He said they will ask companies the reasons for the bid price difference.

In past, İzmir has examples of not giving work to lowest bidder. Most recent example Fahrettin Altay - Narlıdere subway tunnel work. There work as awarded to company giving closest price to median price. Work was awarded to Gülermak.

But this time I feel lowest price will be awarded because Gülermak gave lowest. Gülermak wants to get İzmir work. Because in other parts of Türkiye work is awarded to companies close to Erdoğan's party in general. This time tender rules different. Because European Bank for Reconstruction and Development (EBRD) provide 125 (increased from 80) million euro credit for the 1 Billion 70 million cost project.  Because of this foreigners were allowed to participate in tender.

According to municipality website: "With deep tunnel method using Tunnel Boring Machine (TBM) and NATM 13,5km long tunnel 11 stations will build. Subway tunnels work automatic without drivers.
