Chinese authorities are developing a 3D model of the Beijing City walls and building plans, but experts warn it could still be years before they can be built.
They are proposing to upgrade the walls to 3d, and have created a 3d rendering of their proposed construction plans which they hope will convince the world that this is the way forward.
“This is an extremely promising development,” said Professor Michael D’Andrea, from the University of Warwick.
In a blog post published on Thursday, the city government said the plan “could transform the architecture of the city wall in a matter of decades”.
The new plans would see a new concrete wall be built in the eastern sector of the walls, replacing the old concrete wall and the existing steel and concrete wall, with a glass wall in the western sector, with the same design and materials.
The project has been criticised by some quarters, who have argued that the existing structures are not ready for such a large scale construction, and that the current building works are a waste of money.
“The cost of this project is enormous, and it could be years from now before any of this is completed,” said Dr Sarah Fitch, of the Centre for Science and Society at Leeds University.
However, she added that the plans would “improve the overall condition of the building and will allow the new walls to be installed in a few months, with some major work needed before the completion of the project.”
Construction of the new 3D-printed walls is expected to start in 2018, with work to be completed in 2019.
