About this file
This document appears to be a set of engineering drawings and technical specifications for the replacement of hanger rod assemblies for the shutter structure at Shasta Dam. The drawings provide detailed dimensions and materials requirements for the replacement hanger rod assemblies, including box girders, shutter beams, and connection plates. The key details include:
The replacement hanger rods are to be 59'6" in total length, fabricated from ASTM A572 Grade 50 steel. The drawings provide specific dimensions and detail for the coupler, heavy hex nuts, and plate washers required. The replacement concrete for the connection areas is specified to be an ASTM C387/C387M packaged crack-resistant mix with a minimum 4,000 psi compressive strength. The drawings also note the required clearances, elevations, and layout of the hanger rod assembly in relation to the dam structure.
This document appears to be supporting a federal contract opportunity with Solicitation Number 140R2024Q0125, issued by the Department of the Interior's Bureau of Reclamation, for the NCAO Shasta Dam TCD Hanger Rod Installation project.
