Prefab proving fabulous in challenging environment

Finding building materials suitable for use on the "Roof of the World" has always been an engineering challenge - let alone actually putting them together.

So experts from Shanghai Jiao Tong University decided to do half the job elsewhere.

They are using prefabricated steel studs to construct inexpensive and environmentally friendly structures in the Tibet autonomous region. The materials can adapt to its cold and high-altitude environment with high seismic intensity.
