Smarter infrastructure spending needed for growth: study

MGI estimated that the world needs to spend $57 trillion on infrastructure - the sinews of an economy - between now and 2030 simply to keep up with projected growth. That is nearly 60 percent more than the $36 trillion spent over the past 18 years.

Yet government budgets are tight and banks wary of lending, so wringing more out of each dollar of investment is imperative to sustain growth, jobs and development, MGI, the research arm of the consultancy McKinsey & Co, said in a report.

MGI estimated that extending the best practices it identified in 400 projects worldwide could lead to a 60 percent productivity improvement. In the United States, Japan and Germany, for example, construction workers have not increased their productivity in the past 20 years.

"Countries could deliver $48 trillion of infrastructure for only $30 trillion in investment and reinvest the savings," the report said.

Those savings would come from three main sources: selecting projects more systematically and delivering them more efficiently; making the most of existing airports, roads and ports; and managing demand by using tools such as road pricing and water metering.

"The practices that would yield this $1 trillion a year are already in place. We are not looking into the future to see what new technology might bring," Herbert Pohl, one of the report's authors, told Reuters.
