These are mechanical engineering design drawings for a mechanical system rehabilitation project at Steamtown National Historical Site in Scranton, Pennsylvania. The comprehensive set of 16 technical drawings details extensive mechanical upgrades across multiple buildings, including the History Museum and Locomotive Shop. Key scope elements include:

Mechanical system modifications involve demolishing and replacing existing infrastructure such as air handling units (AHUs), hot water and chilled water pumps, boilers, air separators, expansion tanks, and associated piping and electrical systems. The project includes two implementation options (Option 1 and Option 2) with specific requirements for equipment installation, gas line modifications, electrical panel revisions, and system reconnections. Proposed equipment includes new AHUs, pumps, chillers, and control systems, with careful attention to integration with existing infrastructure and preservation of the historical site's mechanical systems. The drawings provide detailed floor plans, flow diagrams, equipment schedules, and installation specifications for comprehensive mechanical system rehabilitation.
