# Palätsch retaining wall replacement on the Peist-Langwies railway line

Rhätische Bahn AG is tendering the replacement of the damaged Palätsch stone retaining wall at kilometre 17.400 between Peist and Langwies. The existing railway-era wall is about 30 metres long and is in condition class 4. The notice calls for its removal and construction of an approximately 31-metre cast-in-place concrete gravity wall, with drainage, backfill and adjustment of the valley-side shoulder protection. Works are scheduled from 3 May to 15 October 2027. Variants are allowed; consortia and subcontracting are permitted, while partial offers are not. Qualification and award criteria are in the tender documents; no value is published.
