C--Provide Architect/Engineering (A/E) Professional Services - MACA Pre-design to Stabilize Retaining Walls

The contract awards professional Architecture and Engineering services to rehabilitate four retaining walls constructed during the Civilian Conservation Corps era at the Green River Ferry Crossing within Mammoth Cave National Park in Kentucky. These walls are critical structural components that support the riverbank and roadway serving as the sole vehicular access to the ferry landing; their failure due to ongoing degradation or a major flood could cause the boarding and disembarking areas to collapse into the river, permanently disabling ferry operations. Services encompass Pre-Design and Schematic Design phases to assess current conditions, develop mitigation strategies, and produce detailed plans for stabilization, ensuring the long-term integrity of this vital infrastructure. The work is being managed by the Department of the Interior through the Ser East MABO office in Atlanta, Georgia, with the primary point of contact being Edward Dingle, reachable via email and phone listed in the contract. Performance of the work will occur exclusively at the site in Mammoth Cave, Kentucky, with a solicitation number of 14PP5126F0005 and NAICS code 541330 indicating architectural and engineering services.
