The Pennsylvania Department of Transportation (PennDOT) aims to raise existing processes and standards from the Digital Delivery Directive (3D2025) initiative to the next level. This pilot project seeks to apply the use of an open data standard that will enable PennDOT and other State DOTs to free themselves from expensive proprietary technologies that make it difficult to exchange information between design and construction teams.
This project builds upon the efforts of the TPF-5(372) BIM for Bridges and Structures Transportation Pooled Fund, a multi-year collaborative effort to develop the first open data standards for the digital exchange of 3D models for conventional workhorse bridges in the U.S. using the Industry Foundation Classes (IFC) standard. This standard has been adopted by AASHTO but has never been used on a U.S. highway construction project. PennDOT will use the products from this national effort to demonstrate the value of open data standards and its practical application to replace conventional bridge plans with advanced 3D models - a practice that improves design accuracy and visualization that also streamlines bidding processes, adopting transparency and competitiveness among contractors. This shift not only enhances the sharing of information between stakeholders, but it provides the framework for small and disadvantaged businesses to access construction technology that until now has been out of reach due to the expensive nature of proprietary systems.
The project's ambitions extend beyond PennDOT's benefit, fostering collaborations with state and local governments in the world of digital as-builts. This approach envisions training initiatives throughout the pilot project. PennDOT, as host of utility data, provides accessibility for local and state entities, creating a comprehensive information library.
The open data formats produced by this project will be usable in all aspects of project delivery, including public outreach. For example, digital imagery can be used to provide a visual trajectory of project progress to help the public understand the complexity and challenges of bridge construction, forging a deeper connection with the public. This approach embodies our commitment to involving stakeholders and enhancing their understanding of our initiatives.
The project's vision extends beyond construction boundaries to environmental protection. Visualization technology comes to the forefront, enabling real-time evaluation of sensitive areas, leading to optimized decisions, and reduced ecological footprints. The versatility of 3D models empowers efficient equipment planning, regardless of project scale or complexity.
Regarding safety, the project adopts a pioneering approach. With digital technologies, the exposure of construction staff and traffic disruptions in work zones are minimized, improving safety while maintaining an efficient workflow. This commitment resonates with PennDOT's dedication to creating a safer working environment for all. These benefits are shared equitably across the entire community, ensuring that every member benefits proportionately. This commitment to fairness pushes inclusivity and shared success among all community stakeholders.
