Extension of a retirement home complex
In the course of extensions to a retirement home complex in Hamburg, planning services for the outdoor facilities and drainage of a new building in addition to the existing rainwater and wastewater drainage were required.
The property of 2.5 ha, which is located on Schillingsbek, was fitted out with barrier-free outdoor facilities. The footpaths were constructed with low longitudinal gradients and crossfalls. Special concrete paving without bevels was selected for the surfacing in order to increase accessibility to residents with walking aids.
A rainwater retention system of 55 m in length was constructed for the draining the new building. The existing drainage to the existing buildings was extended using a reservoir infiltration ditch which had a retention function and relieved the outflow volume into the Schillingsbek. The basis of this was formed by the calculated rainwater outflow and dimensioning of the required retention volume. Planning services also included obtaining all the required building and water rights permits.
