The construction industry is big business. A recent study has predicted that global construction output will increase by more than 70%, to US$15 trillion per year worldwide, by 2025. The dominant sources of this growth will be three countries in particular, China, India and the U.S., with much of the remainder in the emerging markets.

This growth is a cause for celebration, but it will not come without challenges. Some of those countries where the highest growth is predicted are also perceived as having the highest levels of corruption.
