Z--A250 Emergency Repairs to Pier 1

The National Park Service is seeking a contractor to perform emergency repairs to Pier 1 in the Charlestown Navy Yard of Boston National Historic Park. The work includes repairs to concrete encased steel beams, sinkholes, and concrete delamination, as well as repairs to the existing steel barge and the connection between an aluminum gangway and concrete deck platform. The estimated magnitude of the project is between $1,000,000 and $5,000,000. • The project requires the contractor to repair concrete encased steel beams, sinkholes, and concrete delamination. • The contractor must also repair the existing steel barge and the connection between an aluminum gangway and concrete deck platform. • The project has a tight schedule, with all work to be completed by the end of the period of performance, which is approximately 72 calendar days. • The contractor will need to work around existing utilities and other site constraints. • The project requires the contractor to reuse excavated soils as backfill, and to restore disturbed areas to their original condition.
