Based in Madrid, OHL has over 23,000 employees and an impressive average yearly growth rate of 20% since 2002. In the third quarter of 2010, its net sales amounted to over 3,4 billion Euros. At the same time, OHL is strongly committed to environmental responsibility and in 2003 produced its first Sustainable Development Report. As Juan-Miguel Villar Mir, the chairman of the board of directors and the author of the report, noted, mindful attention to the long-term health of the environment creates a "virtuous circle" that benefits the company, its clients and the globe. OHL's ecological diligence has served it well in Mxico, where strong government regulations are enforced to protect the environment. A presence in Mxico since 1980, OHL employs over 3,400 people there and has built highways, bridges, hotels and hospitals. The tourism complex at Mayakoba, which will eventually include two or three golf courses and six luxury hotels, is OHL's most ambitious hospitality project to date.
