Robinson Surveys provided land surveying services for the MTA/NYCTA Second Avenue Subway Project. This project is a major $16 Billion subway project running eight miles beneath Second Avenue in Manhattan from the financial district to 125th Street. The DMJM+HARRIS / ARUP Joint Venture sub-contracted the Aerial Mapping assignment to Robinson Aerial Surveys, Inc.
The Second Avenue Subway will reduce overcrowding and delays on the Lexington Avenue line, improving travel for both city and suburban commuters and improving access to mass transit for residents of the East Side of Manhattan. The project began in January 2002. The Metropolitan Transportation Authority and New York City Transit Authority have initiated the preliminary design for the full length of the project.
The Robinson team was responsible for land surveying services and obtaining low-altitude mapping photography (LAMP) at 1”=100’ scale to produce topographic mapping at 1”=20’ scale with one-foot contour intervals in MicroStation format. The photogrammetric base mapping was produced for the entire eight-mile project corridor centering on Second Avenue.
