China's construction industry has experienced a sustained                      building boom. A rapidly industrializing economy, rural migration                      to the cities, intensive infrastructure development and the                      replacement of many obsolete buildings has fueled construction                      growth. Infrastructure investment is a key element of China's                      Tenth Five Year Plan (2000-2004), with a special focus on                      roads, rail systems, ports and airports, and energy. Continued                      massive infrastructure investment by the Chinese government,                      high economic growth rates, rapid urbanization and the awarding                      of the 2008 Summer Olympics to Beijing promise to foster continued                      growth in urban construction for years to come.
