This document is an architectural plan and photographic assessment for Congress Hall in Philadelphia, Pennsylvania, specifically an attic plan (A2-2.5) for a Building Monitoring Program at Independence National Historical Park. The plan is dated 05/20/98 and shows the layout of the attic space with detailed structural and mechanical components marked for monitoring or remediation.

The architectural drawing identifies thirteen specific areas of concern throughout the attic space, marked with numbered circles (1-13) on the plan. These areas correspond to photographic documentation on the second page showing existing conditions including structural elements, mechanical systems, chimney structures (labeled as Chimney 1 and Chimney 2), ductwork, piping, electrical components, and wood framing conditions. The notes on the plan reference existing conditions requiring documentation, including references to existing mechanical pipes and ductwork to be removed or relocated, new mechanical pipes and ductwork to be installed, new openings to be provided, sprinkler piping modifications, heat circulation requirements, and new guard rails. The documentation suggests this is part of a comprehensive building monitoring and remediation assessment for preservation and maintenance purposes at this historical property.
