This presentation will provide a case study on how the Metropolitan Transportation Authority – NY (henceforth MTA) approaches and implements BIM and Digital Twins, including valuable insights, lessons learned, and best practices. It will also examine the software stack on which MTA has standardized for BIM and Digital Twins, and describe data management practices employed for these technologies.

MTA owns and/or operates significant transportation assets in the NYC Metropolitan Area, including a subway and bus network within the city itself, commuter railroads out to the suburbs, and several vehicular bridges & tunnels. MTA has been implementing BIM on select capital projects for the last 15 years. Over the past few years MTA has started combining other digital data, such as point clouds, reality models, and photogrammetry with the BIM models, thus creating Digital Twins. Since 2022, BIM has been required on a greater portion of capital projects, thus accelerating the rate of implementation. Although MTA’s assets are primarily horizontal, early BIM projects focused on discrete, vertical facilities, such as passenger stations, fan plants, bus depots, and signal buildings. However, over the past few years MTA has also been modeling horizontal (civil) assets that are receiving capital work, such as tracks, bridges, and subsurface utilities.
