The new report, Global Construction 2025, from Global Construction Perspectives and Oxford Economics, states that developing countries will drive construction growth over the long-term. Although emerging markets are expected to lead the way, the report's authors cautioned that growth would be more measured than in the past. Overall, global construction output is expected to grow at 4.3 per cent a year over the next 12 years, compared to 3.5 per cent for GDP growth. Western European construction is expected to under-perform, with an annual average growth of just one per cent, the same rate as the developed countries of Asia-Pacific. Latin America is also expected to be below par, with 3.5 per cent annual construction growth. North American markets are expected to be more or less on the global trend at 4.2 per cent annual growth, while Eastern Europe (4.6 per cent) and the Middle East and North Africa (4.9 per cent) are expected to be ahead of the curve. The most robust growth is expected to be in sub-Saharan Africa (5.0 per cent) and emerging Asia-Pacific (+6.9 per cent). Of the 46 key countries surveyed, Qatar is expected to be the fastest growing construction market, with an average annual rate of +10 per cent.
