Steel and Aluminum Bronze miter gate parts for Pittsburgh District, USACE

This government file details specifications for various construction components, primarily for horizontally framed miter gates, likely for projects managed by the US Army Corps of Engineers, Pittsburgh District. It includes technical drawings and material requirements for items such as miter contact blocks and quoin contact blocks, both made from ASTM A240 Type 304 stainless steel. The document also outlines critical instructions for other components (CLIN 003 to CLIN 012), including specific material requirements like A36 Structural Steel, welding electrodes (AWS A5.4, E309, E7018), and essential testing protocols such as destructive testing, NDT (Non-Destructive Testing), and welding submittal requirements. Tolerances, finishes, and specific assembly instructions, including the prohibition of all-thread rod and requirements for single-point threading, are emphasized. The document underscores the importance of precise manufacturing and assembly to ensure the functionality and safety of the final structures, with particular attention to how components fit together, such as the full engagement of a stud in a wedge pin and the proper installation of a gudgeon pin after a press fit.

This document outlines the specifications for manufacturing and supplying various miter gate parts, designated as MAX24 RESTOCK MITER GATE PARTS, for government use.
