The document, "Exhibit A – Dredging Extents," serves as an introductory exhibit within a government solicitation, likely for an RFP or grant related to dredging projects. Its primary purpose is to define and outline the approximate dimensions and extents of areas slated for dredging. The explicit note that "All dimensions and extents are approximate" is a key detail, indicating that the provided measurements are estimates and subject to change or further detailed engineering. This exhibit is crucial for bidders or grantees to understand the scope of work involved in a dredging project, providing foundational information for project planning and cost estimation within the context of federal, state, or local government procurement.

The U.S. Coast Guard Yard in Curtis Bay, Maryland, is undertaking the Shipyard Infrastructure Optimization Project (SIOP) to modernize its facilities for a new class of Cutters arriving by 2030. This initiative, partnered with USACE Baltimore District, involves two main projects: dredging the federal channel and extensive waterfront optimization. The latter includes the demolition and reconstruction of Pier 2, Pier 3, South Wharf, and Building 68, along with associated infrastructure. The project will follow a Design-Build to Budget approach, prioritizing innovation and "best solutions" over the "cheapest." The procurement process involves two phases: Phase 1 selects three offerors based on past performance, technical approach, and lead designer, while Phase 2 selects a single offeror through iterative proprietary meetings to refine design, schedule, and cost. Key considerations include minimizing operational disruption during construction and potential contractor procurement and installation of pier cranes. Construction is anticipated to be complete by CY 2030.
