Infrastructure investing has taken a transformative turn over the past decade. Whereas the design, building and maintenance of projects was primarily in the hands of all levels of government (depending on the needs of the project), those projects have moved more into the hands of private investors, especially those of large institutional investors. According to a report by PwC and the Global Infrastructure Investor Association (GIIA), titled, Global Infrastructure Investment: The role of private capital in the delivery of essential assets and services, more than $200 billion has been raised by specialist funds since 2006, with at least the same amount allocated by pension funds and other direct investors.
