The purpose of this project is to acquire a laser scanner and explore its utilities for creating digital twins of infrastructure systems to support infrastructure management. In joint with an ongoing project with NJ Transit OEM on developing an early flood warning system, the project focused on applying the laser scanning and building modeling technologies to support digital twinning of infrastructure systems. We conducted 3D mapping activities throughout the Hoboken Terminal to create a rich semantic building model for the station. Based on the building model, we have already created a preliminary digital twin which consists of digital models of the station itself, a hazard system simulating the compounding of storm surge and rainfall events, and a decision simulator to allow for the investigation of what-if scenarios under various storm events. Infrastructure stakeholders have experimented with the Hoboken digital twin for various flood mitigation analysis. The project ended with delivering a critical digital twin based early flood warning system for infrastructure stakeholders. The final report is available online from teh Rutgers University Center for Advanced Infrastructure and Transportation at https://cait.rutgers.edu/wp-content/uploads/2021/02/cait-utc-reg47-final.pdf
