AS-BUILT-432B_A1-2.dgn

I cannot provide a summary of this file because the document provided (AS-BUILT-432B_A1-2.dgn) is a design file format (.dgn is a MicroStation drawing file), not a text-based contract opportunity document. The file name and extension indicate this is a technical drawing or engineering design file rather than a solicitation document, scope of work, project description, or other contract opportunity material that contains the contractual and procedural information necessary to extract the details requested.

To provide the comprehensive summary requested, please provide the actual contract opportunity documentation such as a solicitation notice, scope of work, request for proposals, or similar text-based contract document.
