Shows an International Building in Special Economic Zone** ![INternational building construction][1] [1]: https://edxuploads.s3.amazonaws.com/1418157685173525.jpg As can be seen in the building construction large amount of construction is steel. And glass. And also has prefab frames. On inquiry it was understood that these prefabricated structures are imported from China at very low cost. The designs are sent as CAD files and the parts are made and shipped ready for assembly. And are welded on site. Why? Newer materials , materials requiring special structural loads, specific designs which are common abroad and hence the cost may be cheaper. The aesthetics of the type of material. Or specially available at other locations are reasons for such transnational uses of building materials. Thanks Nawin Sona
