About this file
This document appears to be a technical drawing and specifications for guard posts and related components for a federal contract opportunity. The drawing provides details on the construction of steel pipe sleeves, concrete bases, and reinforcement for guard posts in a non-security application. It includes specific dimensions, materials (steel pipe, HDPE pipe, concrete), and fabrication requirements. The drawing references a related federal contract opportunity for the Hyrum Dam Spillway Replacement project, which involves the construction of a new spillway and removal of the existing spillway, associated mechanical and electrical features, roadway realignment, and other civil works. The project is being procured by the Department of the Interior Bureau of Reclamation, with an anticipated performance period from March 2025 through January 2029.

Unless noted otherwise, galvanize pipe sleeve and lower bar after fabrication per ASTM A385.
Fabricated Metalwork:
Bars _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ASTM A36 Std. Steel Pipe _ _ _ _ _ _ _ _ _ _ _ _ _ ASTM A53, Grade B Rebar _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ASTM A615
HDPE Pressure Pipe: ASTM F405.
Unless noted otherwise, make all welds continuous and in the shop.
Unless noted otherwise, fabricator shall determine edge preparation and root opening for groove welds.
Arc-Welding Electrodes: Filler metal and required shielding gases or fluxes shall be per AWS D1.1 with filler metal for steel having a minimum tensile strength of 70,000 psi.
Rockfill per ASTM C33, Coarse Aggregate, Size No. 57.
