August the 20th, 2026 – As Zagreb invests over 3 million euros in tram track renovation, it seems that work to get them completed quickly will see boots on the ground at night, at weekends and even on holidays.
Poslovni reports that the procurement procedure also includes four stationary devices for lubricating tram rails, including their delivery, installation, commissioning and functional testing. For the repair of tram tracks, the City plans to allocate 3.1 million euros. A public procurement is being prepared for works on tram infrastructure, ranging from the replacement of damaged concrete elements and cover plates to the arrangement of tracks and surfaces along the rails. The work would be ordered successively over two years, depending on the condition of the tracks and needs on the ground.
The City of Zagreb plans to conclude a framework agreement with several economic operators, and when the need for a specific intervention is established, the contractor will receive a written request. Work must then begin no later than within 36 hours, and individual contracts may last up to 12 months.
The City is conducting the procedure for ZET, and the documentation provides for the possibility of carrying out works during the day, but also at night, from 22:00-06:00, with slowed or completely suspended tram traffic. Contractors must be prepared to work on weekends and holidays as well, while works may take place simultaneously at a maximum of three locations.
According to the bill of quantities, there will be no shortage of work. Planned, among other things, is the dismantling of around 2,800 reinforced concrete cover plates, while 3,300 are planned to be installed. The removal of 2,500 concrete elements and the installation of 2,000 new ones is also envisaged. The works include the renovation of elements along the rails, their fastening and levelling, after which the track will again be closed with reinforced concrete plates, asphalt concrete or crushed stone, Večernji list reports.
The interventions also cover surfaces between and along the rails. The removal of a total of 2,200 square metres of the existing base layer is planned, as well as the asphalting of 2,000 square metres of roadway surfaces and an additional 100 square metres of pedestrian surfaces. On sections of the tracks where the track is closed with concrete and asphalt, the removal of around 500 cubic metres of existing fill and the construction of a new one is planned. Works will also be carried out on the crushed-stone base and track fill, in a total quantity of 200 cubic metres.
The procurement also includes four stationary devices for lubricating tram rails, including their delivery, installation, commissioning and functional testing. The City notes that the quantities in the bill of quantities are indicative, so the actual quantities executed, as well as the final cost, may be higher or lower than planned.
It should also be recalled that works are currently entering the final phase at the intersection of Savska and Vukovarska streets, one of Zagreb’s busiest junctions. Since the beginning of July, tram switches and crossings have been being replaced there, and according to the City’s latest available data, the asphalt wearing course has been completed on the greater part of the intersection.
At the same time, a major reconstruction of the tram track in Zvonimirova Street is underway. According to the latest status from the construction site, all earthworks have been completed, around 50 percent of the new rails have been laid, and the concreting of the reinforced concrete slab is currently being carried out. This will be followed by backfilling with crushed stone and the continuation of laying the new track. In addition to the main section of Zvonimirova, works are also being carried out at the intersection with Šubićeva Street, where the reconstruction of the worn-out track structure, including the replacement of a tram switch, began in mid-July.
