About this file
This document is a Questions and Answers file for a federal contract opportunity for Wire Arc Additive Manufactured (WAAM) Parts. The Q&A addresses technical details about nondestructive testing, welding procedures, and manufacturing specifications. Key points include clarification that NDE (nondestructive evaluation) will only be required for manually welded components, with x-ray imaging performed according to AWS D.1.5 standards. The document confirms that inspections will occur once during the build process and once before component shipment, with a delivery location in Galveston, TX to be specified at award time.
Offerors are instructed to provide a cost breakdown for both as-printed parts with machining stock and final machining, including associated lead times. The solicitation is a 100% Small Business set-aside under NAICS code 333248, with proposals due by 1:00 PM CST on 23 June 2025. The procurement is being conducted by the US Army Corps of Engineers Engineer Research and Development Center (ERDC) Geotechnical and Structures Laboratory, with the intent to establish a Blanket Purchase Agreement (BPA) for recurring WAAM part procurement. Submissions should be emailed to Jennifer Hoben and David Ammermann, with technical and pricing evaluations determining the most advantageous offer.

The following questions and answers are provided for informational purposes only:
Question #1: Our engineering department is requesting clarification on the nondestructive testing. Can you please specify the required techniques and the procedural specification and acceptance specification for each technique?
Answer #1: NDE will only be required for manually welded components or splices. If the component is manually welded, the component will be subjected to x-ray imaging for defects according to AWS D.1.5.
Question #2: To further elaborate on the request, the SOW mentions both AWS D1.5 and AWS D20.1 for acceptance criteria. We would like clarification on what procedure and acceptance criteria are being applied and to what process step (i.e. is the reference to AWS D1.5 only application if the component is spliced?)?
Answer #2: ASME BPVC SEC IX article VI 'Material Manufacturing Using Wire-Additive Welding’ governs. AWS D1.5 and AWS D20.1 are only if the component needs to be manually spliced/welded. This particular component should be capable of being manufactured without a manual weld/splice and therefore would not need AWS D1.5 and AWS D20.1.
Question #3: While Galveston, TX is mentioned for estimating cost, will a more exact delivery address be provided at the time of award for logistical planning?
Answer #3: Yes, specific delivery location will be provided at time of award. Galveston, TX can be used for budgetary purposes.
Question #4: Are there any preferred time windows or protocols for Government inspection during fabrication, or will these be coordinated post-award?
Answer #4: Inspections will happen once during build, date to be determined after award, and once before shipment of component.
Question #5: Should we quote only the WAAM-printed part with machining stock, or is the final machined finish (as per 2D drawings) to be included?
Answer #5: Cost breakdown for as-printed with machining stock and separate final machining should be provided with associated lead times.
Question #6: Can you confirm the scale of the object to be around 40-50mm? What material is it made from?
Answer #6: All dimensions are provided in the drawing and all material specifications are outlined in the Description of Requirement (DOR) document which has also been provided.
