Summary

Machine-generated summary

The tender covers building works at the SWW Lengg site. The planned renovation comprises the complete renewal of the waterproof roof sealing above the Slow Filter South basins, together with the professional repair of damaged ceiling and exterior wall joints. The aim of the measures is to sustainably ensure the watertightness of the structures and to protect the building fabric over the long term against moisture ingress and the resulting consequential damage. The works consist of civil and construction trades, including demolition and reinstatement of the roof covering layers and joint refurbishment, to be carried out on the existing water treatment structures in place.

Description

Die vorgesehenen Sanierungsmassnahmen umfassen die vollständige Erneuerung der Dachabdichtung über den Langsamfiltern Süd sowie die fachgerechte Instandsetzung der schadhaften Decken- und Aussenwandfugen. Ziel der Massnahmen ist die nachhaltige Sicherstellung der Dichtheit der Bauwerke sowie der langfristige Schutz der Baukonstruktion vor Feuchtigkeitseintritten und den daraus resultierenden Folgeschäden.
