And it's all done by a Nanjing private enterprise.

If traditional technology is used to transform this unsafe bridge, the cost will be more than 150,000 yuan, and the construction duration will be at least 1 month. But now the use of 3D technology, it costs only about 50,000 to 60,000 yuan. It only takes 10 days from processing to installation. In addition to the benefits of cost savings, this technology is also environmentally friendly. The 3D technology will then be used in the construction of the southern new city.
