November the 14th, 2026 – The City of Zagreb will finally get a brand new tram line, after over six months of “combing through” all of the submitted bids.
The powers that be in the City of Zagreb have once again selected GIP Pionir as the winner of the tender issued back at the beginning of July. Over two whole years after it was announced, the tender for works on the tram line along Heinzelova and Radnička streets can now proceed. Poslovni reports that the State Commission for the Control of Public Procurement Procedures (DKOM) rejected the appeals of two companies that participated in the public procurement procedure estimated at 48 million euros, so the selection of the contractor can finally be completed and preparations for the start of works can begin soon.
This finally brings to an end the long-running complication surrounding one of the capital projects that the City of Zagreb announced back in 2023 and officially launched in November 2024. The first tender for the contractor of works on 3.7 kilometres of new tram track was announced at the end of 2024, but as the bids received significantly exceeded the estimated amount of 48 million euros (excluding VAT, as with other amounts in the text), the City cancelled the tender and announced a new one in May 2025. The value of the project remained the same, and by July four bids had been received.
After a two-month evaluation, the job was awarded to GIP Pionir, and then the problems began. A consortium of bidders led by the company Texo Molior, which also participated in the tender, decided to lodge an appeal, and the State Commission for the Control of Public Procurement Procedures (DKOM) upheld that appeal in January this year. The Commission ordered the City of Zagreb, as the contracting authority, to go through all the bids again and decide on the best one, which they did this summer. This brings us to the new problem.
As can be seen on the Electronic Public Procurement Noticeboard (EOJN), the company had to send several explanations and supplements to its bid over the past six months. A few days later, however, another appeal against the selection decision arrived at DKOM. The procedure was initiated by the same consortium of bidders as the previous time, namely the companies Texo Molior from Cavtat and Zagreb’s Tigra. The City waited three months for the Commission’s decision in the first appeal procedure, the re-selection of the contractor lasted more than six months, and it has now waited almost another four months for the new DKOM decision. The appeal was rejected and the procedure can now continue.
The project, incidentally, in addition to laying new kilometres of track, also includes the reconstruction and protection of 1.4 kilometres of water supply infrastructure along Heinzelova Street and Radnička Road, as well as the reconstruction of sewer collectors built between 1920 and 1950. Only after these works are completed will it be possible, as the City of Zagreb previously explained, to start work on the new line with a total of nine tram stops.
