A method for assembling an exhaust hood for a turbine is provided. The method includes providing a bearing cone that substantially circumscribes a rotor of the turbine; and positioning a guide radially outward from the bearing cone. The guide and the bearing cone are configured to channel fluid from the turbine. The method also includes extending a guide cap from the guide. The guide cap is oriented to facilitate preventing the generation of fluid vortexes within the exhaust hood.
