This document is an architectural drawing set for a penthouse roof framing plan. The drawings provide detailed structural specifications for a multi-level residential or commercial penthouse project, depicting roof framing systems, opening details, deck configurations, and edge closure assemblies.

The design includes typical roof joists at 16-inch on-center spacing with specifications for fastening, bridging, and diagonal bracing. Key components detailed in the drawings are roof deck joist types (open and closed), beam reactions, column connections, closure angle framing around the perimeter, and various opening details for equipment access. The specifications address deflection tracking for architectural and mechanical drawings, equipment weight requirements, and structural tolerances. Multiple typical details are provided for small unframed roof openings, roof deck at columns, roof deck edge closures, and penthouse roof framing assemblies. The drawings include coordination notes regarding deck orientation, no-plate reinforcement requirements for small openings, and closure placement requirements. Architectural and mechanical notes specify minimum screw quantities, fastener types (including Hilti fasteners), and maximum spacing allowances. The document serves as construction documentation for steel deck contractors and structural engineers implementing the penthouse roof system.
