Building Information Modeling - Construction of Part of Second Avenue Subway - 72nd Street/ 2nd Avenue Station, New York, NY

The Second Avenue Subway (SAS) project is New York City’s first major expansion of the subway system in over 60 years. The first phase of the SAS project will provide services from 96th Street as an extension of the existing Q Line train. The project improves subway access for Manhattan’s East Side, bringing transit service closer to those who walk a long distance to the Lexington Avenue Line. It also reduces overcrowding and improves reliability on the Lexington Avenue Line; the city’s most heavily used subway line. The SAS project improves subway access for people with disabilities, as all stations will be in compliance with ADA Act. The 72nd Street Station will have three new entrances, including 11 escalators and five street-level ADA accessible elevators at the southeastern corner of 72nd Street and Second Avenue. The current work in this area is a $250M contract and includes construction of mezzanine and platforms, ancillary structures, station entrances, and mechanical, electrical, and plumbing systems for the station.

EnTech was a subconsultant to Judlau Contracting. EnTech developed a building information model of the station in Bentley AECOsim Building Designer V8i in compliance with the MTA BIM requirements. Around 800 sheets of contract architectural and structural 2D drawings were turned into an integrated 3D Master Model in 8 weeks. The model contained the station cavern, structural slabs, beams, and columns in addition to all architectural features, including but not limited to walls, doors, claddings, pavements, stairs, railings, facades.
