Operational Impact
The use of a digital twin as the primary contract document revolutionized the East 138th Street Bridge replacement project. The digital twin allowed NYSDOT to accurately design and generate a 3D model that helped identify and resolve costly issues before construction. It also facilitated efficient collaboration with utility owners and the public, enabling stakeholders and the community to understand the complex project staging without having to review hundreds of traditional plan sheets. The digital twin also proved extremely helpful with prefabricating and installing the required modular deck beams, allowing the contractor to visually see the installation being specified in the contract while providing all the required design information electronically for the fabricator. The 4D simulation generated from the 3D model provided stakeholders a visual understanding of the project staging in just minutes, and the animated rendering of the construction process helped alleviate public concerns. The project sets new standards using a digital twin as the primary contract document, industrializing delivery of the East 138th Street Bridge. | |
Quantitative Benefit
The digital twin resulted in the winning bid being 15% lower than anticipated. | |
The 4D simulation saved stakeholders from manually sifting through over 200 pages of planning documents. | |
The digital twin will be continuously updated to reflect design changes and the as-built environment, providing a tool for asset management and bridge inspection. | |
