  • Abstract:
    As-built drawings are an essential part of construction project documentation. They capture changes made during construction, deviations from as-designed plans, and provide asset-specific information for use in the operations and maintenance (O&M) phase of roadway facilities. Traditionally, as-built drawings were presented as two-dimensional (2D) paper-based markups, later transitioning to paperless image-based scans and document-based Portable Document Formats (PDFs). While the paperless formats made the files more accessible, they were static representations of the as-built conditions. With technological advancements, digital as-builts (DABs) have emerged as a better alternative than traditional practices. Throughout the project lifecycle, the DAB serves as a central repository of asset information, continuously evolving as new data are collected, organized, and managed. Starting from the design phase, the DAB is enriched with as-built information during construction and then becomes a valuable resource for operations, maintenance, and asset management. With this information, DABs can provide a comprehensive representation of the physical built infrastructure using data-rich three-dimensional (3D) models. DABs also serve as a key information management link throughout the project lifecycle, from design and construction to operations, maintenance, and asset management.
