SOURCES SOUGHT/REQUEST FOR INFORMATION FOR

Radiographic Testing (RT) of a large aluminum weldment for Letterkenny Army Depot (LEAD)

The Army Contracting Command, Redstone Arsenal – Letterkenny Army Depot (ACC-RSA-LEAD) is issuing this Request for Information (RFI) and Source Sought announcement to gain information from industry and seek sources capable of and interested in providing radiographic testing (RT) of a large aluminum weldment, approximately 14x11x4 FT and thickness of weld joints 1.5-2.0” (more in some locations). All services will be expected to be performed at LEAD. Service provider will be expected to travel to LEAD within 24 hours notice to perform RT operations. Requirements could range in service timeline required and could be subject to daily needs or perhaps months-long gaps in service. Requirements will be expected to meet list of standards provided. Servicer will be responsible for bringing all required equipment for operation from taking images to evaluating them on-site.

Methodology whether film, computer, or digital is permitted and subject to contractor discretion and shot requirements. There will often be real-time need for results with asset production and welding being on-hold until RT is completed. Current production outlook is 18 cabs / units in total. 3 cabs will require 100% RT in compliance with print 12940852 E Redline to include all ~230 shots per cab, even those struck out by the redlines. The other 15 cabs will require RT in compliance with 12940852 E Redline as it is written, ~ 37 shots required per cab. There are provisions in the 12940852 print for sampling plans and rework outcomes which would require additional shots to be taken on failed cab and those that follow. The overall project is expected to span late 2026 through 2031.

The purpose of providing this information is to conduct Market Research and identify interested sources capable of inspecting these items.

Corporate Experience & Capability

5. Company Experience: Describe your company's experience over the last five years in performing radiographic testing (RT) on large aluminum weldments, particularly for military or aerospace applications. Please provide at least two examples of similar projects, including the scope, duration, and customer.

6. On-Site Operations: Detail your experience in setting up and conducting RT operations at a client's facility, specifically at a government or military installation like an Army Depot.

7. Turnaround Time: The requirement states a need for real-time results as asset production will be on hold. Describe your standard process for providing on-site image evaluation and delivering immediate results to production personnel. What is your typical turnaround time from image capture to providing a pass/fail determination?

Personnel Qualifications

8. Certifications: Confirm that all personnel who will perform and interpret radiographic tests are certified in accordance with MIL-STD-3057, ASNT CP-189, or NAS410. Please specify which certification(s) your personnel hold and their certification levels (e.g., NDT Level II, Level III).

9. Inspector Experience: Provide details on the qualifications and years of experience of the NDT Level II or Level III inspectors who would be assigned to this project. Specifically, detail their experience with interpreting radiographs of aluminum welds according to military standards like MIL-STD-2035A and MIL-STD-1895.

Technical Approach & Equipment

10. RT Methodology: The requirement permits film, computed, or digital radiography. Which method(s) does your company specialize in? Describe the advantages of your proposed methodology for this specific application (large aluminum structure, variable shot requirements).

11. Equipment: Provide a comprehensive list of the equipment you would bring on-site to perform all required tasks, from image capture to on-site evaluation. Include details on the radiation source (X-ray/Gamma-ray), imaging plates/film, processing/scanning equipment, and viewing/evaluation software and hardware.
