  • Abstract:
    Recognizing the imperative of enhancing efficiency, accuracy, collaboration, and adaptability, the New York State Department of Transportation (NYSDOT) acknowledges the necessity for a robust data management strategy. This strategy aims to facilitate the seamless exchange of information through digital-as-builts (DABs) during the transition to digital workflows. Currently, for design-bid-build (DBB) projects, NYSDOT generates designs in a three-dimensional (3D) model in-house, converts the model, and delivers the work as two-dimensional (2D) information. Contractors then use the 2D information to reconstruct the necessary 3D details. However, this process is challenging due to incomplete and inaccurate information during the 2D to 3D conversions. Consequently, NYSDOT is actively seeking ways to specify contractual work using various electronic file formats, such as DGN, XLS, XML, and PDF, with the potential to minimize or eliminate data loss during information transfer. In the past decade, and particularly following the implementation of a geographic information system (GIS) web-based and enterprise-level asset management system in 2011, NYSDOT has improved integration of DAB processes and construction as-built data. The significance of this advancement is underscored by the incorporation of Building Information Modeling (BIM), which brings additional layers of collaboration, visualization, and data-driven decisionmaking to further streamline and optimize the project lifecycle. This Technical Brief presents a comprehensive analysis of BIM delivery approaches in various project delivery methods, especially on DBB and design-build (DB) projects. Comparing BIM delivery approaches in DBB and DB is critical for informed decisionmaking, optimizing collaboration, identifying the best practices, and ensuring that BIM is used to effectively enhance the overall success of construction projects.
