Details

Popravilo kavitacijskih poškodb. Na opremi turbin (lopate gonilnikov, glave gonilnikov, kape gonilnikov, predvodilne lopatice, vodilne lopatice, lopatice razbremenilnikov, jeklene obloge sesalnih cevi, vratu turbine in razbremenilniki) vseh agregatov na DEM prihaja med obratovanjem do kavitacijskih poškodb, ki jih je treba sanirati. Sanacije se izvajajo v času revizijskih obdobij. Poškodbe se sanirajo z varjenjem (reparaturno varjenje, navarjanje), brušenjem in poliranjem. Sanacije poškodb se izvajajo v zaprtih in izpraznjenih pretočnih traktih turbin do višine približno 4 m od delovnih površin. Vključeno je tudi popravilo ostalih poškodb na vodooblivnih delih turbin. Ostala varilska dela. Na hidroelektrarnah imamo veliko jeklenih konstrukcij in opreme (vtočne rešetke, pomožne zapornice, žerjavi, čistilni stroji, razne druge jeklene konstrukcije in oprema), kjer se tudi pojavljajo poškodbe, razpoke, obraba, izvajajo manjše predelave in podobno. Popravila izvajamo z varjenjem. Sanacije poškodb se izvajajo v zaprtih prostorih, na prostem, ob ali nad vodo ter na raznih višinah (žerjavi). S predmetnim razpisom razpisujemo dela za popravilo kavitacijskih poškodb in ostalih varilskih delih na vseh objektih DEM za časovno obdobje 1. 1. 2027 do 31. 12. 2028. Na podlagi izvedenega razpisa bomo sklenili okvirne sporazume za obdobje 2 let, z odpiranjem konkurence po dejanskih potrebah.

Documents

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this facility management & cleaning opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
  • Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
  • Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
