Overview
- Omid Nouripour says horizontally installed SML drainage pipes are corroding and generating sewer-like smells in the Reichstag plenary area and the Jakob-Kaiser-Haus.
- He says replacing the defective pipes is planned as part of remediation after earlier fixes to leaky roofs proved temporary.
- He faults original aesthetic choices, including flat roofs, for leaving the buildings prone to leaks and failures during heavy rain.
- Roughly two-thirds of Bundestag buildings need renovation over the next 20 years, affecting about 800 to 1,000 offices, according to his estimate.
- For the Luisenblock Ost 1 project, he warns costs may surpass €1 billion versus nearly €900 million previously, while an architecture competition for Luisenblock Ost 2 is underway this year.
