This is an existing and demolition plan for an E-wing penthouse, drawn at a scale of 1/4" = 1'-0". The plan shows the floor layout of a penthouse space with key areas labeled and marked for either retention or removal. The document identifies an AC unit, HVAC system, E-wing penthouse structure, and control/sensor equipment positioned throughout the space. Various numbered reference points (18-21) are marked along the perimeter, with a north orientation indicator provided. Colored highlights indicate status zones: green markers denote areas or components designated for demolition or removal, while pink/red markers identify areas to be retained or preserved. The plan includes mechanical, electrical, and plumbing (MEP) elements such as PHL PCPA, PHL PRPA, sensors, and Honeywell PNL connections. Additional annotations reference BEMS WIRING and DMMD equipment on the eastern wall. The drawing appears to be a preliminary planning document used to guide renovation, reconfiguration, or demolition activities in the penthouse space.
