The solicitation seeks professional engineering assistance, including engineering studies and design, to advance the Foss Park Avenue Realignment Project and the associated Naval Station Great Lakes (NSGL) Base Access Analysis to construction-ready status. The project includes evaluating existing and future access at NSGL gates and identifying a preferred access strategy, with engineering plans, cost estimates, right-of-way documentation, and contract documents to support future implementation. The study area covers Foss Park Avenue, NSGL access gates, nearby transportation corridors, utilities, and surrounding properties, with attention to gate closures, emergency routing, transportation performance, and infrastructure resilience.
