S2-1 Drawing.jpeg

This is an architectural drawing set containing structural design details for a penthouse roof framing system. The document presents multiple detailed plans and sections for a residential or commercial construction project, including a South Penthouse Roof Framing Plan, Center Penthouse section, grillage plan, and various connection details.

The primary structural elements depicted include roof framing specifications with timber joists and beams, grillage systems with detailed dimensions, moment connections between structural members, brace elevations showing diagonal bracing patterns, base plate details for column foundations, and rod connection specifications. The drawings include notation references to existing conditions such as concrete column locations and require field measurement of existing columns prior to fabrication. Key details address connections between new W10 base plates and existing concrete columns, with specifications for embedment and anchor rod placement. The plans contain multiple circled reference numbers (1-9) linking detailed sections throughout the document, and various notes regarding construction tolerances, existing conditions that must be verified, and fabrication requirements. This appears to be a design document prepared for structural steel fabrication and installation rather than a federal contract solicitation document.
