Att 1. VBS Mesh Spec Drawing.pdf

This is a supply contract sketch for the Lower Granite Lock and Dam project, consisting of technical drawings for VBS (Vertical Baffle Screen) mesh panels. The document presents detailed specifications for mesh panel fabrication across two figures: Figure 3 of 4 depicting mesh panels 1-7 (typical of 126 panels) and Figure 4 of 4 depicting mesh panel 8 (typical of 18 panels).

The drawings specify precise dimensional and material requirements for the mesh panels, including finished mesh widths of 19'-1" total, individual panel widths of 9'-2", and heights ranging from 2'-9¾" to 3'-5⅜" depending on panel location. Key specifications include 6x6 mesh construction measuring 19'-1" x 9'-4¾", vinyl edging strips of varying widths (3½" for side edges, 7" and 12" for top and bottom edges), and vinyl reinforcement strips with 9" minimum width finished. The panels feature vinyl edging strips finished on specific edges: side edges on panels 1-7, top edges on panels 1-7, and bottom edges on panel 8. The sketch was designed and drawn by CRP/JAH with the most recent date of 22 JUN 2017, referencing FRAC No. (Facility Reallocation Approval Code) documentation. The technical specifications provide contractors with precise fabrication requirements necessary for manufacturing these mesh screen components.
