About this tender
This is a notice of abandonment (publication #45066-03, dated 23.10.2026) for an open-procedure construction tender, 'Hochwasserschutz Dorf Alpthal - Vormassnahmen' (flood protection preliminary measures for the village of Alpthal), issued by Bezirk Schwyz - Abteilung Umwelt. The page does not contain the original scope, deliverables, or duration of the works; those details would be in the earlier invitations (#45066-01 and #45066-02), which are not included here. The buyer states that the tender is being abandoned because eligibility criterion EK1, a requirement for ISO 90001 certification, was wrongly demanded. A new tender for the same project is to be published on 16.10.2026 without the ISO 90001 requirement. All other conditions, requirements and documents are said to remain unchanged. The submission deadline moves to 16.11.2026 at 16:00. The notice also gives instructions on legal remedies: an appeal against the abandonment may be filed in writing with the Verwaltungsgericht des Kantons Schwyz within 20 days of this notice, under Art. 52 ff. IVöB. No court holidays apply. The notice has internal date inconsistencies. It is dated 23.10.2026 yet refers to a new tender published on 16.10.2026, which is earlier. The anchor closing date (2026-11-13) also differs from the 16.11.2026 deadline stated in the body. The body text is treated as the authoritative source here.
Bidder eligibility
Original eligibility criterion EK1 required ISO 90001 certification. The buyer states this was wrongly required and will be removed in the re-issued tender published on 16.10.2026. Other eligibility conditions are described as unchanged but are not listed on this page. (The standard is written as 'ISO 90001' in the notice, which may be a typo for ISO 9001.)
Key requirements
- Design and construction of sediment collectors (Geschiebesammler) with concrete intake and steel-reinforced outlet structures on four streams
- Channel widening and bed reinforcement using concrete-embedded blocks and threshold structures to increase flood-discharge capacity
- Terrain modification and deflection dam construction in upper forest reaches
- Utility relocation (water and spring-water pipelines) prior to main works
- Access road construction with gravel-grass surface for maintenance
