RIO DE JANEIRO, April 25 (Xinhua) -- Rio's government launched on Monday an international competition to choose the project of the Olympic Park for the 2016 Games.
The area will host several sports facilities of the Olympic Games; 15 different competitions will be held at the Park. Some of the facilities will be permanent and others might be used for other purposes after the Olympics.
According to Rio's Economic Development Secretary, Felipe Goes, the projects will have to take into consideration the existing facilities built for the 2007 Pan-American Games, such as the Maria Lenk Aqua Park and the basketball arena. Rio's race track, however, will be demolished.
Goes also stressed that the environmental aspects of the project will be taken into consideration, such as the low water and energy use and the preservation of nearby lagoons.
"The chosen project must consider environmental concerns and avoid unnecessary governmental expenditures," he said.
Companies will have to present the projects by the end of June. The winning project will be known by mid-July.
