Loading, transport and recovery treatment of up to 3,000 tonnes of concrete railway sleepers

Summary

The tender covers the removal of up to approximately 3,000 tonnes of concrete railway sleepers from two stockpiles on the railway section between Kuartango and Urkabustaiz: around 2,500 tonnes at Zuhatzu Kuartango station and around 500 tonnes at Izarra station. The contractor must load and transport the sleepers to an authorised waste facility, arrange their treatment and handle the environmental documentation. The material is non-hazardous waste (LER code 17 01 01), and its treatment must include recovery rather than disposal. Work must proceed continuously at a rate of at least 200 tonnes per day. Payment is based on the actual tonnage treated and supported by documentation. Bidders must provide the required transport and waste-treatment authorisations and meet the technical, legal and submission requirements in the tender documents.
