About this tender

The buyer, Pannon-Víz Zrt., is procuring no-dig rehabilitation (trenchless relining) construction works on its water and wastewater networks for 2026-2027. This notice covers Part 1 (1. rész), which is associated with the Győr Operations Engineering Unit (Győri Üzemmérnökség). Part 1 includes a second part referenced in the text, but its scope is not included in the extracted content. The works involve installing a cured-in-place liner with a hardening epoxy resin bonded to the existing pipe. Part 1 covers five sites in Győr with a total length of 2,692 running metres: 490 m of potable water mains (240 m of NA400 steel pressure main in the Holt Rábca floodplain and 250 m of the Nyugati főnyomó NA400 main) and 2,202 m of wastewater sewers. The wastewater scope includes NA350, NA400, NA30/45 and NA40/60 concrete sewers on the Szent István u. / Jókai u. / Benczúr u. section, the Szent István u. / Bisinger sétány / Aradi Vértanúk u. section, and the Zrínyi u. section. Sewer works include house connections, gullies (víznyelők) and roof-water drains, with 20 connections on one section and 52 on another, and 16 on the Zrínyi u. section. All affected pipes and sewers are within the urban built-up area. The specification prioritises minimising excavation, since no-dig execution depends on limiting on-site demolition. The notice warns that several sites have decorative paving, and that disturbing it could add unrealistically high costs. The notice does not state the contract duration or the individual delivery milestones.
