Harvesting an abundance of oil and natural gas resources, the Middle East supplies nearly half of all exports to the global oil market. Middle Eastern countries Iran, Iraq, Kuwait, Qatar, Saudi Arabia and the United Arab Emirates are all members of the Organization of the Petroleum Exporting Countries (OPEC), which pumps roughly 40% of the world's oil, with Saudi Arabia leading the pack for the greatest amount of output. OPEC's crude oil production was 28.7 million barrels per day in the first half of 2009.
Civil engineering is the discipline dealing with the design, construction, and maintenance, typically of public works such as roads, bridges, canals and buildings. Civil engineers can be involved in nearly every stage of a construction project – from site selection, writing specifications for materials, reviewing bids, and supervising construction. They aim to design and build structures that meet requirements for safety, reliability, cost, and energy efficiency.
