Building Information Modeling Consulting - Reconstruction of Part of Second Avenue Subway - 63rd Street/ Lexington Avenue Station, New York, NY

This $167 Million subway infrastructure project is the 2nd largest project ever undertaken by the MTA NYCT. The first phase of the project involves constructing 4 miles of new subway line along the 2nd Ave in Manhattan, carrying more than 200,000 daily commuters. The 63rd Street/Lexington Ave Station is one of the major hubs and transfer points along this line, connecting the East and West side of Manhattan. The scope of work for this project involves the open-cut excavation for the construction of entrances and ancillary facilities, removal and upgrade of structural elements within the existing tunnels, and traction power connections. This complex project has an extensive variety of drawings from several disciplines including architectural, EnTech Project Number 11051 structural, mechanical, and electrical. Changes to part of existing structure as shown in contract drawings to achieve that goal, temporary steel structure will be installed and existing structure will be removed and then the proposed structure will be erected.

EnTech was the BIM consultant for this MTA project. EnTech duties included developing the 3D model for all areas including lower platform, upper platform and six (6) mezzanine levels in the Revit platform based on 2500 sheets of 2D contract drawings, developing structure model in Tekla, and creating steel demolition/erection sequences based on contract documents. EnTech linked labor resources for demolition and erection activities based on the contractor resources, and performed MEP and architectural coordination and clash detection. EnTech BIM team finished the 3D model in less than 3 weeks, which resulted in better understanding and coordination for the project team.
