A report by Goldman Sachs reveals Russia’s requirement for further infrastructure investment. The report, Russian Infrastructure and Construction, shows that investments in transport corresponded to 1.5-1.7% of GDP in 2005-2010. For Russia’s total infrastructure needs, including power networks and communications, spending equated to 3.7-4.3% of GDP. But the report shows Russia should allocate at least 3.5-4.5% of its GDP to infrastructure while maintenance of existing infrastructure should make up about 50%
