In Simple Terms
In Shanghai, instead of demolishing an old school for new construction, engineers moved the entire building using robot legs. This innovative technique preserves historic buildings while allowing urban development to continue. It shows a smart way to solve the challenge of modernizing cities without losing their heritage.
A Revolutionary Move in Shanghai
In the fall of 2020, a unique event unfolded in Shanghai’s Huangpu district. Engineers decided to relocate an old school building rather than demolish it to make room for a new commercial complex. The building in question was the Lagena Primary School, constructed in 1935. Instead of using traditional methods like wheels or rails, the engineers employed a novel technique involving robotic legs to move the building.
The Technology Behind the Move
To accomplish this feat, a team from Shanghai Evolution Shift cut the building’s supporting columns and separated it from its foundations. They then lifted it using hydraulic supports that functioned like robotic legs. These supports carried the entire building, allowing it to be moved to its new location.
This technology is notable for its ability to move along curved paths, making it superior to traditional straight-rail methods. For instance, in 2003, the Shanghai Concert Hall was moved using a straight path, which wouldn’t have suited irregularly shaped buildings like Lagena School.
The Process and Timeframe
The relocation of the school took 18 days, covering a distance of 62 meters with a 21-degree rotation. The movement was slow and deliberate to prevent any damage to the building. Lan Wuji, the project’s technical supervisor, highlighted his company’s expertise in moving buildings along curved paths, a key advantage of this technology.
Why Move Instead of Demolish?
The decision to move the building rather than demolish it was driven by several factors, including the preservation of the city’s historical heritage and the potential cost savings of relocation versus demolition and reconstruction. Additionally, developers plan to transform the relocated building into a center that combines cultural education with the preservation of intangible heritage.
Conclusion
The relocation of Lagena Primary School in Shanghai serves as a pioneering example of addressing urban development challenges without sacrificing historical heritage. This innovative technique could pave the way for more projects that preserve old buildings while solving urban challenges in sustainable and intelligent ways.
