An article on Friday, Sept. 21 about faculty involvement with the MIT 2030 plan incorrectly stated that one of two new MIT building projects is an expansion of the Central Utilities Plant, replacing Building 41. That project is instead an Energy/Environment building at the corner of Mass. Ave. and Vassar St., adjacent to Building 41. Its infrastructure needs (along with other campus development) may lead to a future replacement of building 41 with an extension of the Central Utilities Plant.
