IBN Frame Drawings Table 2026-06-15.xlsx

This is a drawing table document prepared for the University of Washington's request for qualified quotes (RFQQ 1230896) for IBN and TTM frame fabrication. The project requires the design, fabrication, testing, finishing, and delivery of 14 structural frames consisting of 12 IBN (Integrated Buoyancy Node) frames and 2 TTM (Tethered Test Module) frames. The delivery deadline is December 15, 2026, with earlier delivery acceptable. The drawing table specifies the complete bill of materials and components required for manufacturing, listing 24 distinct drawing numbers with corresponding part names, assemblies, and quantities needed to construct the frames.

The IBN frame components require 12 units of lower weldment assemblies, base plates, lower frames, and outboard/inboard side load supports, along with 14 units of upper weldment assemblies, lifting frame weldments, upper frame crossbars, upper frames, parking position parts, bail arm assemblies, and associated support and anode plates. The TTM frame configuration requires 2 units of lower weldment assemblies, base plates, TTM-specific lower frames, and side load supports. Additionally, 14 cable protector parts for the IBN frames are specified. This technical specification document serves as the engineering reference for bidders to understand the complete scope of fabrication requirements and material specifications necessary to meet the contract deliverables.
