This is a technical engineering drawing for a vertical and portable dock structure produced by Sun Shipbuilding & Dry Dock Co. The document contains detailed specifications and cross-sectional views for dock construction, including multiple sections (labeled as Section 3-A1 through Section 3-A5) that illustrate various structural components and assembly requirements. The drawing includes detailed measurements, material specifications, and design notes for cl-ridder components, backing bars, and structural connections. The blueprint shows the overall dock platform configuration with reinforced structural elements, mounting details, and various elevation views. The document appears to be a historical engineering specification, likely from the mid-20th century based on the drawing style and notation conventions. While this is a technical specification document rather than a federal contract solicitation document, it could serve as reference material or technical specification documentation supporting a government contracting opportunity related to dock construction, repair, or modification services. The drawing provides the detailed technical requirements that would typically be referenced in a contract performance work statement or statement of work for dock-related construction or manufacturing services.
