About this tender

The Municipality of Birwinken (Gemeinde Birwinken - Strassenbau und Werke) is procuring transport, recovery, treatment and disposal services for excavated soil and earth material contaminated mainly with lead and antimony. The material arises from the remediation of the 300 m shooting range at Birwinken (KbS-Reg.-Nr. 4901 D 10a/b), located at the backstop (Kugelfang) in Birwinken, 8585 TG, Switzerland. The procedure is an open tender under the Intercantonal Agreement on Public Procurement (IVöB). Services include providing and scheduling suitable transport vehicles (skips and tippers), hauling away the material fractions released by the specialist site supervision, and recovering, treating or disposing of the materials at licensed facilities. Heavily contaminated material must be treated in a soil washing plant. The contractor must also prepare the required consignment notes and transport and disposal records. The estimated total quantity is about 2,540 tonnes of contaminated soil and excavated material across different contamination classes. Actual quantities and material allocations may change based on results of investigations during the works. Excavation, material separation and loading are tendered separately and are not part of this tender. Evaluation quantities are for comparison only and are not guaranteed. Execution is planned for 10 January to 25 March 2027, in coordination with a separately contracted civil works company. The start is subject to required permits. The contract duration is not specified and the contract may not be extended.
