For example the soil of America is very different collectively than that of China or any other country. This variation is also present within the country. The seismic zones are different.

This variation can be easily observed in civil engineering as every project has different sets of characteristics despite of the fact that even if materials and requirements are taken as same. International Council of Building Officials having their headquarter in California has published this code for the very first time way back in ICBO was meant to promote Public safety by providing standards and requirements to ensure safe construction.
