Attachment L - REF DWGS-B171-1999.pdf

This is a comprehensive set of architectural and engineering drawings for a roof and exterior repair project at Building 171 for the Norfolk Naval Shipyard (NNSY) in Portsmouth, Virginia. The project involves replacing the roof for Group II and includes detailed plans for demolition, new work, electrical systems, plumbing, and building sections across multiple floors. The drawings provide extensive technical specifications for roof replacement, including roof deck plans, exterior elevations, building sections, and various detailed technical drawings covering structural, mechanical, and electrical components. Key elements include roof demolition plans, new roof installation details, floor plans for multiple levels (first, second, third, mezzanine), electrical and plumbing layouts, and specific technical details for roof penetrations, drainage, and structural modifications.

The project documentation includes comprehensive notes, legends, and abbreviations that outline construction requirements, materials specifications, and installation guidelines. The drawings are meticulously drafted with multiple reference points, grid systems, and detailed annotations for each section and floor. The scope appears to be a comprehensive renovation of the building's roof and associated systems, with careful attention to existing conditions, structural integrity, and modern building standards. The drawings are prepared by an architectural and engineering firm, with the naval shipyard location suggesting this is a federal government infrastructure improvement project.
