Albert Einstein monument in Ulm
Customer: Stadt Ulm – Zentrales GebäudemanagementConstruction period: 1 month Year of construction: 2023
- Lifting up of the Einstein monument in Ulm by 48 cm, as it was wrongly positioned during a conversion of the place to make it handicapped accessible. Its symbolism – showing a 24-hour day – was lost because there were only 22 hours still visible. After the lifting up of the monument all 24 building blocks are visible again and the day has 24 hours again in Ulm.
- By means of 4 hydraulic presses with 16 t (10 cm uplift) each, as well as 8 further presses (with a larger surface but less uplift) for temporary load-bearing the monument was lifted up.
- Subsequently the horizontal adaptation to the existing building structures was carried out, so that all 24 building blocks with a height of 40 cm are visible again. The monument was put onto 6 bearers in horizontal position, a new concrete foundation was produced and the last 5 cm cast with poured concrete.
