Summary

Machine-generated summary

The contract covers gardening works as part of the roof renovation of the slow filter facility South at SWW Lengg. The roof surfaces, totalling around 5,200 m2, must be completely stripped. This includes removing the existing green roof, including shrubs, trees and the existing soil substrate. Once the waterproofing and repair works are completed, the contractor will restore the roof surfaces and re-establish the green roof in line with current ecological requirements. The works combine demolition and clearance of the old planting with the new greening of the roofs.

Nach Abschluss der Abdichtungs- und Instandsetzungsarbeiten werden die Dachflächen wiederhergestellt und unter Berücksichtigung aktueller ökologischer Anforderungen neu begrünt.
