The contract is classified as a service and the portal identifies it as a single-provider framework agreement. The notice gives reference 6-1094-26 and names Novi Sad as the buyer location. It does not state an estimated value, technical service frequencies, qualification thresholds, or award scoring on the accessible public detail. The portal lists a submission cutoff of 27 October 2026 at 09:00 but provides no timezone; the feed timestamp conflicts with that displayed clock, so only the calendar date is reliable here. - Status: open - Country: RS - Buyer: ЈАВНО ВОДОПРИВРЕДНО ПРЕДУЗЕЋЕ "ВОДЕ ВОЈВОДИНЕ", НОВИ САД - Submission deadline: 2026-10-27 (date) - Original notice: https://jnportal.ujn.gov.rs/tender-eo/397721 - Source checked: 2026-10-14T18:32:52.655763Z ## Source-backed public facts ```json { "id": "8ebcce11-ece0-4884-9566-78a10e7a23d0", "revision": 2, "modifiedAt": "2026-10-14T18:37:55.040162+00:00", "sourceCheckedAt": "2026-10-14T18:32:52.655763Z", "stale": false, "url": "https://zephior.com/tenders/8ebcce11-ece0-4884-9566-78a10e7a23d0/central-heating-maintenance", "locale": "en", "title": "Maintenance of the central heating system", "summary": "The public procurement portal of Serbia lists an open procedure by Vode Vojvodine for maintenance of its central heating system.
