About this file
This technical drawing is a detailed schematic for Link Bar and Tube Assembly components for a Submergible Traveling Screen (STS) at the John Day Lock and Dam, part of a U.S. Army Corps of Engineers project in Oregon. The drawing (JDF-9-3-4A60_2) specifies precise manufacturing requirements for link bars, including material specifications (ASTM 500 tube, ASTM A36 plate), dimensional tolerances, welding guidelines, and specific fabrication instructions such as drilling .257" holes, creating 16 holes on 6" centers, and applying specific welding techniques.
The associated federal contract opportunity (Solicitation W9127N25QA020) seeks the procurement of 2,160 Standard STS Linkbars (16-hole) and 144 Master STS Linkbars (31-hole), classified under NAICS Code 332312 with a small business size standard of 100 employees. The solicitation is unrestricted, requires SAM registration, and calls for technical and pricing submissions including manufacturer details and technical specifications. Delivery is specified to the John Day Dam and Willow Creek Project in Rufus, OR, with quotes valid for 30 days from solicitation close and expected delivery by 04 April 2025.
