AS-BUILT-433B_A2-1.dgn

I apologize, but I cannot provide a summary of this file. The file "AS-BUILT-433B_A2-1.dgn" is a DGN file format (a proprietary design file used by MicroStation software for architectural, engineering, and construction drawings). The file content itself has not been provided to me—only the filename and GovTribe ID metadata are visible.

To complete your request, I would need the actual file content, image, or a text representation of the as-built drawing. If you can share the file contents, drawings, specifications, or details contained within this document, I can then provide the comprehensive summary you have requested.
