This document is a construction drawing set for modifications to Congress Hall and Old City Hall in Philadelphia, Pennsylvania. The drawings include site plans, floor plans, elevations, and detailed sections showing the proposed work to be performed.

The project involves modifications to an existing hall structure, with construction drawings depicting ramp and stair modifications, hall independence modifications, and structural details. The drawings include site location maps showing the buildings' positions within Philadelphia, multiple floor plan views with dimension annotations (measurements in feet and inches), elevation views showing the vertical profile of the structures, and detailed construction sections illustrating connections, materials, and assembly methods. The drawings are marked with sheet numbers 1 through 12, with multiple views per sheet including plan views, section views, and detail callouts referenced throughout the set. Construction details specify materials and methods for components such as stairs, railings, foundations, and structural supports. The drawing set appears to be for design or bidding purposes, providing comprehensive technical documentation of the proposed modifications necessary for the alteration work.
