Drainage System Installation at School and Kindergarten Expansion

This tender concerns the installation of a drainage system for a school and kindergarten expansion in Delmenhorst, Lower Saxony, Germany. The project involves connecting rainwater drainage from the new classroom building (gutters, floor drains, and downpipes) to the existing rainwater drainage system. Wastewater connections are also required. A key aspect is the construction of a pumping station for sewage and the installation of a grease separator, likely for the school kitchen. The boundary for the plumbing work ends at the property's transfer shaft outside the building, encompassing the merging of the systems and the layout of the manholes. Further piping and structures in the outdoor area will be covered separately.

The project appears to involve both internal and external plumbing work, indicating a need for a contractor with expertise in both areas. The requirement for watertight and groundwater-resistant underground pipes and manholes points to a need for careful selection of materials and installation techniques. The inclusion of a pumping station and grease separator suggests a moderate level of complexity. The relatively short tender period (March 12 to May 12) implies a need for quick evaluation and efficient bid preparation.

The text provided seems to imply the drainage work inside the building stops at the junction box on the outside of the building. This implies that high-rise work (inside the building) will be more limited. The main focus seems to be on the external drainage on the property.
