This document is Exhibit 4 of the Rail Infrastructure Work Program (926DR012) for the Regional Transportation District (RTD) in Colorado. The exhibit presents the Southwest Corridor Alignment for the rail infrastructure initiative. RTD is seeking contractors with demonstrated expertise in full-depth reconstruction, interim repairs, and modernization preparation of the existing rail system while maintaining operational continuity. The RFI specifically excludes design professionals and is intended to collect industry feedback on the general project approach and methods to accelerate the project schedule. The document consists of eight pages containing technical alignments and infrastructure work program details for the Southwest Corridor component of the broader rail infrastructure initiative.

The document does not contain specific information regarding pricing terms, contract duration, renewal options, set-asides, incumbent contractors, funding sources, or budget amounts within the provided content. The exhibit focuses on the physical and technical alignment specifications for the Southwest Corridor project rather than procurement terms, financial arrangements, or contractual conditions. Interested contractors should review additional procurement documents and the primary RFI announcement for complete information regarding solicitation timelines, submission requirements, evaluation criteria, and funding mechanisms.
