New Kindergarten Roof and Foundation Waterproofing with Green Roof

This public tender in Riegelsberg, Saarland, Germany, focuses on roofing and waterproofing for a new kindergarten. The project requires installation of a 450 sq m flat bitumen roof system topped with an extensive green roof. Additional roofing work includes 90 meters of coping. The waterproofing component involves applying 26 sq m of horizontal waterproofing to the foundation slab. This suggests a need for experience with both traditional roofing materials (bitumen, coping) and green roof systems, including knowledge of drainage layers, growing medium, and plant selection suitable for extensive applications. The relatively small area of the foundation waterproofing suggests a focus on preventative measures during construction rather than remedial work. Absence of a published deadline necessitates immediate investigation to determine bidding eligibility. Furthermore, clarifying missing CPV codes will provide a clearer understanding of the specific material and performance standards required by the contracting authority.
