Nitsch Engineering provided land surveying services for the improvement of service and greater utilization of the Massachusetts Bay Transportation Authority (MBTA) Fairmount Branch. The Fairmount Branch currently travels 9.1 miles between South Station in Boston and its Readville terminus. The project will update the corridor with new and/or improved stations, tracks, and bridge crossings.
In addition to providing new project-specific mapping from aerial photography for approximately 7.4 miles of the corridor, Nitsch Engineering is providing bridge surveys to accommodate the design changes along the corridor. Some bridges will be replaced, while others will be re-decked to accommodate new track alignments and/or stations. In order to provide the designers with the data necessary to replace or renovate the aging structures, Nitsch Engineering is providing a detailed survey of the bridges that have granite abutments, including elevations, stone alignments, material types, and placement of beams, rails, and seats.
