Reconstruction of the 15th century Berlin City Palace, located on Spree Island, sticks to the old design plans. Large quantities of formwork and scaffolding were necessary to ensure rapid construction. More than 109,000 cubic yards of concrete and 16,000 tons of steel were used during reconstruction.
The new building for the Berlin Palace-Humboldt Forum will keep the palace’s original height, depth, roof design, and arrangement of floors. External walls will be built as a solid masonry, keeping their original thickness and sculpted form.
System components made of aluminum, which were lightweight and flexible, saved time and money when forming slabs. Reinforced concrete slabs were formed by systematic shuttering operations.
PERI supplied formwork and scaffolding for the reconstruction of Berlin’s City Palace. On-site support provided by engineers ensured that all the requirements could be fulfilled while maintaining a tight construction schedule.
The outer shell of the Berlin City Palace is 590 feet long, 394 feet wide, and 115 feet high. A 230-foot-high cupola roof sits atop the building. Due to the PERI solution with external CB Climbing Platforms, no facade scaffolding for the shell construction was required.
With a budget more than $644 million, the reconstructed palace stresses the importance of the location in the center of Germany’s capital for the history and culture of the country.
Berlin’s new landmark will feature international collections and scientific/historical works under the control of the Humboldt Forum. A section of the Central and Regional Library will be located here as well.
The most important project is the reconstruction of the Imperial City Palace which was demolished due to the damage it sustained in 1945 during the war. German President, Joachim Gauck, laid the foundation stone for the Berlin City Palace on June 12, 2013. Exactly two years later, the topping out ceremony was celebrated.
Sustainability and energy efficiency are a top priority in the building project. The plans include a geothermal energy system that reduces the consumption of fossil fuels and consequently decreases CO² emissions by utilizing ground heat.
Not yet financed is the reconstruction of selected historic inner portals, including their corridors, or of the dome’s original decoration. Only the basic structure of the dome can be built within the strict cost framework. The decoration, from the lantern on the top down to the sandstone garlands around its base, cannot.
