Shanghai residents passing through the city’s eastern Huangpu district in October might have stumbled upon an unusual sight: a ‘walking’ building. An 85-year-old primary school has been lifted off the ground – in its entirety – and relocated using new technology dubbed the ‘walking machine.’
…Lagena Primary School was constructed in 1935…
…building was rotated 21 degrees and moved 62 meters…
In the city’s latest effort to preserve historic structures, engineers attached nearly 200 mobile supports under the five-story building, according to Lan Wuji, chief technical supervisor of the project.
The supports act like robotic legs. They’re split into two groups which alternately rise up and down, imitating the human stride. Attached sensors help control how the building moves forward, said Lan, whose company Shanghai Evolution Shift developed the new technology in 2018.
“It’s like giving the building crutches so it can stand up and then walk,” he said.
A timelapse shot by the company shows the school inching laboriously along, one tiny step at a time.
Workers had to first dig around the building to install the 198 mobile supports in the spaces underneath, Lan explained. After the pillars of the building were truncated, the robotic “legs” were then extended upward, lifting the building before moving forward.
Over the course of 18 days, the building was rotated 21 degrees and moved 62 meters (203 feet) away to its new location. The relocation was completed on October 15, with the old school building set to become a center for heritage protection and cultural education.
The project marks the first time this “walking machine” method has been used in Shanghai to relocate a historical building, the government statement said….
Should China move its historic monuments?
In the early 2000s, cities including Nanjing and Beijing — prompted by critics protesting the loss of old neighborhoods — drew up long-term plans to preserve what was left of their historic sites, with protections introduced to safeguard buildings and restrict developers.
