Federal Councilor of Prussian Mansion

The Federal Council building in Leipziger Strasse in Berlin can look back on more than a hundred years of history: it was completed in 1904 under the direction of the architect Friedrich Schulze-Kolbitz for use by the Prussian manor house.

The three-wing complex was partially destroyed in the Second World War. In the post-war period until reunification, the building was used by various GDR institutions. In 1997, under the direction of the Schweger & Partner architecture office, the renovation work began for the Federal Council to move in, which has been meeting here since September 2000.

Today the building presents itself as a modern parliamentary seat and architectural sight.

Implementation of supply and disposal lines through existing walls (masonry) with wall thicknesses from 300 mm to 1650 mm and line diameters from 50 mm to 400 mm. The masonry was provided with a PMBC surface seal. The lines partly in stock and partly in a close arrangement. In addition, the line was close to the base of the building. The project planner's requirement was to create a clean separation between the building and pipe seals.

In such a renovation case, the surface sealing is usually connected by a fixed / loose flange construction or the line sealing is ensured by a casing pipe protruding from the wall. However, since the planner wanted the pipes to run through the entire wall structure in a casing, a special casing construction in the form of a Curaflex® 7006 material 1.4301 was necessary. Including upper and lower lengths for the casing (outside: 100 mm overhang, inside: wall thickness + 20 mm overhang) as well as sizes DN 100 - DN 500. In addition, various media feedthroughs / sealing inserts were installed according to the requirements of the cables.
