About this file
The provided document is Appendix B to a Request for Quotes (RFQ) for the reconstruction of the George Washington Memorial Parkway Mount Vernon Trail in Virginia. The RFQ is being issued by the Department of Transportation Federal Highway Administration (FHWA) under Solicitation Number 693C73-24-R-000018. This appendix contains bridge inspection reports for the project area. The RFQ does not provide details on the specific products or services required, response dates, award dates, pricing terms, set-asides, or other key information. This document appears to be a technical appendix to support the overall RFQ requirements, rather than addressing the core scope of work.
