This is an architectural floor plan for the second floor interstitial space of Building 2 (South Building). The plan is not to scale and shows the internal layout of a facility with multiple rooms and spaces. The drawing includes a detailed representation of various rooms, corridors, mechanical or utility areas (indicated by the grid patterns), stairwells, and other architectural elements. The plan contains a title block indicating it is a second floor interstitial plan, with a north arrow and scale reference. The document is marked as "PHOTO/PHOTOED" and notes an update date of "8/14/25." The title block references "BUILDING 2 PHILADELPHIA" and includes fields for project title, date, photographer, and revision information. This appears to be a technical architectural document used for facility planning, renovation, or construction purposes rather than a federal contract solicitation document.
