About this file
This document contains technical specifications for steel castings required under the solicitation for pier side repair of the USACE Dredge Yaquina. The specifications define the required chemical composition, physical properties, dimensions, and machining details for ASTM A148 Grade 90-60 normalized abrasion resistant steel castings. The castings must meet minimum tensile and yield strengths and be inscribed with finished weights. All patterns used will become government property and must be solid mahogany with identification plates. A rust preventative coating is required on all machined surfaces. The solicitation was issued by the USACE Engineering District Portland under opportunity number W9127N22Q0005 for repair of the dredge operated by the Corps of Engineers.
