The planned Isimba Dam, with the force of the White Nile, would offer the much-needed electricity that the Ugandan government wants, since it could produce 183 megawatts but its reservoir will flood the area around the Kalagala Falls, which means that the ecosystem will be affected.
Construction has started on one of Manhattans newest skyscrapers. Located at 53 W. 53rd St. the MoMA Tower, designed by French architect Jean Nouvel, is to be completed sometime in 2018. Featuring a tapered profile with a roofline staggered across three irregular levels, the 1050-foot tall (82-storey) structure will house 139 apartments and is Nouvel’s first skyscraper in NYC. The tower will also have new public gallery spaces on the second, fourth and fifth floors, into which the neighboring Museum of Modern Art (MoMA) will expand its galleries.
This week San Francisco International Airport turns over its new control tower to the Federal Aviation Administration. The FAA will spend a year outfitting the 221-foot, torch-like, flared cylinder with its systems, testing them and training controllers. The concrete spine of the tower is tied, with steel cables, to a 7-foot thick mat foundation, which is supported by 140-foot deep piers that reach the bedrock below. The tower contains two dampers, each 37,400 pounds, which help the shaft to remain still in high winds and to withstand a magnitude 8 earthquake. The FAA provided the majority of the $120 million dollars needed for project.
