City of Boston seeks a consultant team for a feasibility analysis and concept design of a 0.7-mile greenway over the Red Line tunnel between Ashmont station and Park Street in Dorchester.

The feasibility study includes site survey, structural analysis of the tunnel, mapping and title search of property ownership within the ROW, preparation of a low-cost, easy-to-implement “Quick Build” design, and preparation of a more capital-intensive, long-term concept design. Project requires close collaboration with the City, MBTA, and members of the Dorchester community. A separate consultant is under contract to plan the engagement process.

Timeline: "Ideally" the structural engineering, site survey, and ROW scope would be substantially completed within 12 weeks of Notice to Proceed, the Quick Build design would be completed by the end of 2024, and the concept design for the Long Term Plan would be completed by June 30, 2025. Budget is $600,000; contract is 14 months.
